+ >Android NDK, Revision 9</a> <em>(July 2013)</em>
+ </p>
+ <div class="toggle-content-toggleme">
+ <dl>
+ <dt>Important changes:</dt>
+ <dd>
+ <ul>
+ <li>Added support for Android 4.3 (API level 18). For more information, see
+ {@code STABLE-APIS.html} and new code examples in {@code samples/gles3jni/README}.
+ <li>Added headers and libraries for OpenGL ES 3.0, which is supported by Android 4.3
+ (API level 18) and higher.</li>
+ <li>Added GNU Compiler Collection (GCC) 4.8 compiler to the NDK. Since GCC 4.6 is still
+ the default, you must explicitly enable this option:
+ <ul>
+ <li>For {@code ndk-build} builds, export {@code NDK_TOOLCHAIN_VERSION=4.8} or
+ add it in {@code Application.mk}.</li>
+ <li>For standalone builds, use the {@code --toolchain=} option in
+ {@code make-standalone-toolchain.sh}, for example:<br>
+ {@code --toolchain=arm-linux-androideabi-4.8}</li>
+ </ul>
+ <p class="note"><strong>Note:</strong>
+ The {@code -Wunused-local-typedefs} option is enabled by {@code -Wall}. Be
+ sure to add {@code __attribute__((unused))} if you use compile-time asserts like
+ {@code sources/cxx-stl/stlport/stlport/stl/config/features.h}, line #311. For more
+ information, see
+ <a href="https://android-review.googlesource.com/#/c/55460">Change 55460</a></p>
+ <p class="note"><strong>Note:</strong>
+ In the GCC 4.7 release and later, ARM compilers generate unaligned access code by
+ default for ARMv6 and higher build targets. You may need to add the
+ {@code -mno-unaligned-access} build option when building for kernels that do not support
+ this feature.</p>
+ </li>
+ <li>Added Clang 3.3 support. The {@code NDK_TOOLCHAIN_VERSION=clang} build option
+ now picks Clang 3.3 by default.
+ <p class="note"><strong>Note:</strong>
+ Both GCC 4.4.3 and Clang 3.1 are deprecated, and will be removed from the next NDK
+ release.</p></li>
+ <li>Updated GNU Project Debugger (GDB) to support python 2.7.5.</li>
+ <li>Added MCLinker to support Windows hosts. Since {@code ld.gold}
+ is the default where available, you must add {@code -fuse-ld=mcld} in
+ {@code LOCAL_LDFLAGS} or {@code APP_LDFLAGS} to enable MCLinker.</li>
+ <li>Added {@code ndk-depends} tool which prints ELF library dependencies.
+ For more information, see {@code NDK-DEPENDS.html}.
+ (<a href="http://b.android.com/53486">Issue 53486</a>)</li>
+ </ul>
+ </dd>
+
+ <dt>Important bug fixes:</dt>
+ <dd>

+ <li>Fixed potential event handling issue in {@code android_native_app_glue}.
+ (<a href="http://b.android.com/41755">Issue 41755</a>)</li>
+ <li>Fixed ARM/GCC-4.7 build to generate sufficient alignment for NEON load and store
+ instructions VST and VLD.

+ <li>Fixed {@code libc.so} and {@code libc.a} to support the {@code wait4()} function.
+ (<a href="http://b.android.com/19854">Issue 19854</a>)</li>
+ <li>Updated the x86 libc.so and libc.a files to include the {@code clone()}
+ function.</li>
+ <li>Fixed {@code LOCAL_SHORT_COMMANDS} bug where the {@code linker.list} file is
+ empty or not used.</li>
+ <li>Fixed GCC MIPS build on Mac OS to use CFI directives, without which
+ {@code ld.mcld --eh-frame-hdr} fails frequently.</li>
+ <li>Fixed Clang 3.2 X86/MIPS internal compiler error in {@code llvm/lib/VMCore/Value.cpp}.
+ (<a href="https://android-review.googlesource.com/#/c/59021">Change 59021</a>)</li>
+ <li>Fixed GCC 4.7 64-bit Windows assembler crash. (Error: {@code out of memory allocating
+ 4294967280 bytes}).</li>
+ <li>Updated {@code ndk-gdb} script so that the {@code --start} or {@code --launch} actions
+ now wait for the GNU Debug Server, so that it can more reliably hit breakpoints set
+ early in the execution path (such as breakpoints in JNI code).
+ (<a href="http://b.android.com/41278">Issue 41278</a>)
+ <p class="note"><strong>Note:</strong>
+ This feature requires jdb and produces warning about pending breakpoints.
+ Specify the {@code --nowait} option to restore previous behavior.
+ </p>
+ </li>
+ <li>Fixed GDB crash when library list is empty.</li>
+ <li>Fixed GDB crash when using a {@code stepi} command past a {@code bx pc} or
+ {@code blx pc} Thumb instruction.
+ (<a href="http://b.android.com/56962">Issue 56962</a>,
+ <a href="http://b.android.com/36149">Issue 36149</a>)</li>
+ <li>Fixed MIPS {@code gdbserver} to look for {@code DT_MIPS_RLD_MAP} instead of
+ {@code DT_DEBUG}. (<a href="http://b.android.com/56586">Issue 56586</a>)</li>
+ <li>Fixed a circular dependency in the ndk-build script, for example: If A->B and
+ B->B, then B was dropped from build.
+ (<a href="http://b.android.com/56690">Issue 56690</a>)</li>
+ </ul>
+ </dd>
+
+ <dt>Other bug fixes:</dt>
+ <dd>
+ <ul>
+ <li>Fixed the {@code ndk-build} script to enable you to specify a version of Clang as a
+ command line option (e.g., {@code NDK_TOOLCHAIN_VERSION=clang3.2}). Previously, only
+ specifying the version as an environment variable worked.</li>
+ <li>Fixed gabi++ size of {@code _Unwind_Exception} to be 24 for MIPS build targets when
+ using the Clang compiler.
+ (<a href="https://android-review.googlesource.com/#/c/54141">Change 54141</a>)</li>
+ <li>Fixed the {@code ndk-build} script to ensure that built libraries are actually
+ removed from projects that include prebuilt static libraries when using the
+ {@code ndk-build clean} command.
+ (<a href="https://android-review.googlesource.com/#/c/54461">Change 54461</a>,
+ <a href="https://android-review.googlesource.com/#/c/54480">Change 54480</a>)</li>
+ <li>Modified the {@code NDK_ANALYZE=1} option to be less verbose.</li>

+ <li>Fixed a problem where {@code stlport new} sometimes returned random values.</li>
+ <li>Fixed {@code ndk-gdb} to match the order of {@code CPU_ABIS}, not {@code APP_ABIS}.
+ (<a href="http://b.android.com/54033">Issue 54033</a>)</li>
+ <li>Fixed a problem where the NDK 64-bit build on MacOSX choses the wrong path for
+ compiler.
+ (<a href="http://b.android.com/53769">Issue 53769</a>)</li>
+ <li>Fixed build scripts to detect 64-bit Windows Vista.
+ (<a href="http://b.android.com/54485">Issue 54485</a>)</li>
+ <li>Fixed x86 {@code ntonl/swap32} error: {@code invalid 'asm': operand number
+ out of range}.
+ (<a href="http://b.android.com/54465">Issue 54465</a>,
+ <a href="https://android-review.googlesource.com/#/c/57242">Change 57242</a>)</li>

+ <li>Updated {@code ld.gold} to enable the {@code --sort-section=name} option.</li>
+ <li>Fixed GCC 4.4.3/4.6/4.7 to suppress the {@code -export-dynamic} option for
+ statically linked programs. GCC no longer adds an {@code .interp} section for statically
+ linked programs.</li>
+ <li>Fixed GCC 4.4.3 {@code stlport} compilation error about inconsistent {@code typedef}
+ of {@code _Unwind_Control_Block}.
+ (<a href="http://b.android.com/54426">Issue 54426</a>)</li>
+ <li>Fixed {@code awk} scripts to handle {@code AndroidManifest.xml} files created on
+ Windows which may contain trailing {@code \r} characters and cause build errors.
+ (<a href="http://b.android.com/42548">Issue 42548</a>)</li>
+ <li>Fixed {@code make-standalone-toolchain.sh} to probe the {@code prebuilts/}
+ directory to detect if the host is 32 bit or 64 bit.</li>
+ <li>Fixed the Clang 3.2 {@code -integrated-as} option.</li>

+ <pre>clang: for the -arm-enable-ehabi option: may only occur zero or one times!</pre>
+ </li>
+ <li>Fixed build failure when there is no {@code uses-sdk} element in application
+ manifest. (<a href="http://b.android.com/57015">Issue 57015</a>)</li>
+ </ul>
+
+ </dd>
+ <dt>Other changes:</dt>
+ <dd>
+ <ul>
+ <li>Header Fixes
+ <ul>
+ <li>Modified headers to make {@code __set_errno} an inlined function, since
+ {@code __set_errno} in {@code errno.h} is deprecated, and {@code libc.so} no longer
+ exports it.</li>
+ <li>Modified {@code elf.h} to include {@code stdint.h}.
+ (<a href="http://b.android.com/55443">Issue 55443</a>)</li>
+ <li>Fixed {@code sys/un.h} to be included independently of other headers.
+ (<a href="http://b.android.com/53646">Issue 53646</a>)</li>
+ <li>Fixed all of the {@code MotionEvent_getHistorical} API family to take the
+ {@code const AInputEvent* motion_event}.
+ (<a href="http://b.android.com/55873">Issue 55873</a>)</li>
+ <li>Fixed {@code malloc_usable_size} to take {@code const void*}.
+ (<a href="http://b.android.com/55725">Issue 55725</a>)</li>
+ <li>Fixed stdint.h to be more compatible with C99.
+ (<a href="https://android-review.googlesource.com/#/c/46821">Change 46821</a>)</li>
+ <li>Modified {@code wchar.h} to not redefine {@code WCHAR_MAX} and
+ {@code WCHAR_MIN}</li>
+ <li>Fixed {@code <inttypes.h>} declaration for pointer-related {@code PRI} and
+ {@code SCN} macros. (<a href="http://b.android.com/57218">Issue 57218</a>)</li>
+ <li>Changed the {@code sys/cdefs.h} header so that {@code __WCHAR_TYPE__} is 32-bit
+ for API levels less than 9, which means that {@code wchat_t} is 32-bit for all
+ API levels. To restore the previous behavior, define the {@code _WCHAR_IS_8BIT}
+ boolean variable. (<a href="http://b.android.com/57267">Issue 57267</a>)</li>
+ </ul>
+ </li>
+ <li>Added more formatting in NDK {@code docs/} and miscellaneous documentation fixes.
+ </li>
+ <li>Added support for a thin archive technique when building static libraries.
+ (<a href="http://b.android.com/40303">Issue 40303</a>)</li>
+ <li>Updated script {@code make-standalone-toolchain.sh} to support the {@code stlport}
+ library in addition to {@code gnustl}, when you specify the option
+ {@code --stl=stlport}. For more information, see {@code STANDALONE-TOOLCHAIN.html}.</li>
+ <li>Updated the {@code make-standalone-toolchain.sh} script so that the
+ {@code --llvm-version=} option creates the {@code $TOOLCHAIN_PREFIX-clang} and
+ {@code $TOOLCHAIN_PREFIX-clang++} scripts in addition to {@code clang} and
+ {@code clang++}, to avoid using the host's clang and clang++ definitions by accident.
+ </li>
+ <li>Added two flags to re-enable two optimizations in upstream Clang but disabled in
+ NDK for better compatibility with code compiled by GCC:
+ <ul>
+ <li>Added a {@code -fcxx-missing-return-semantics} flag to re-enable <em>missing return
+ semantics</em> in Clang 3.2+. Normally, all paths should terminate with a return
+ statement for a value-returning function. If this is not the case, clang inserts
+ an undefined instruction (or trap in debug mode) at the path without a return
+ statement. If you are sure your code is correct, use this flag to allow the
+ optimizer to take advantage of the undefined behavior. If you are not sure, do not
+ use this flag. The caller may still receive a random incorrect value, but the
+ optimizer will not exploit it and make your code harder to debug.</li>
+ <li>Added a {@code -fglobal-ctor-const-promotion} flag to re-enable
+ promoting global variables with static constructor to be constants. With this flag,
+ the global variable optimization pass of LLVM tries to evaluate the global
+ variables with static constructors and promote them to global constants. Although
+ this optimization is correct, it may cause some incompatability with code compiled
+ by GCC. For example, code may do {@code const_cast} to cast the constant to mutable
+ and modify it. In GCC, the variable is in read-write and the code is run by
+ accident. In Clang, the const variable is in read-only memory and may cause your
+ application to crash.</li>
+ </ul>
+ </li>
+ <li>Added {@code -mldc1-sdc1} to the MIPS GCC and Clang compilers. By default, compilers
+ align 8-byte objects properly and emit the {@code ldc1} and {@code sdc1} instructions
+ to move them around. If your app uses a custom allocator that does not always align
+ with a new object's 8-byte boundary in the same way as the default allocator, your app
+ may crash due to {@code ldc1} and {@code sdc1} operations on unaligned memory. In this
+ case, use the {@code -mno-ldc1-sdc1} flag to workaround the problem.</li>
+ <li>Downgraded the event severity from warning to info if {@code APP_PLATFORM_LEVEL} is
+ larger than {@code APP_MIN_PLATFORM_LEVEL}. The {@code APP_PLATFORM_LEVEL} may be lower
+ than {@code APP_PLATFORM} in {@code jni/Application.mk} because the NDK does not have
+ headers for all levels. In this case, the actual level is shifted downwards. The
+ {@code APP_MIN_PLATFORM_LEVEL} is specified by the {@code android:minSdkVersion} in
+ your application's manifest.
+ (<a href="http://b.android.com/39752">Issue 39752</a>)</li>
+ <li>Added the {@code android_getCpuIdArm()} and {@code android_setCpuArm()} methods to
+ {@code cpu-features.c}. This addition enables easier retrieval of the ARM CPUID
+ information. (<a href="http://b.android.com/53689">Issue 53689</a>)</li>
+ <li>Modified {@code ndk-build} to use GCC 4.7's {@code as/ld} for Clang compiling.
+ <p class="note"><strong>Note:</strong>
+ In GCC 4.7, {@code monotonic_clock} and {@code is_monotonic} have been renamed to
+ {@code steady_clock} and {@code is_steady}, respectively.</p></li>
+ <li>Added the following new warnings to the {@code ndk-build} script:
+ <ul>
+ <li>Added warnings if {@code LOCAL_LDLIBS/LDFLAGS} are used in static library
+ modules.</li>
+ <li>Added a warning if a configuration has no module to build.</li>
+ <li>Added a warning for non-system libraries being used in
+ {@code LOCAL_LDLIBS/LDFLAGS} of a shared library or executable modules.</li>
+ </ul>
+ </li>
+ <li>Updated build scripts, so that if {@code APP_MODULES} is not defined and only static
+ libraries are listed in {@code Android.mk}, the script force-builds all of them.
+ (<a href="http://b.android.com/53502">Issue 53502</a>)</li>
+ <li>Updated {@code ndk-build} to support absolute paths in {@code LOCAL_SRC_FILES}.</li>
+ <li>Removed the {@code *-gdbtui} executables, which are duplicates of the {@code *-gdb}
+ executables with the {@code -tui} option enabled.</li>
+ <li>Updated the build scripts to warn you when the Edison Design Group (EDG) compiler
+ front-end turns {@code _STLP_HAS_INCLUDE_NEXT} back on.
+ (<a href="http://b.android.com/53646">Issue 53646</a>)</li>
+ <li>Added the environment variable {@code NDK_LIBS_OUT} to allow overriding of the
+ path for {@code libraries/gdbserver} from the default {@code $PROJECT/libs}.
+ For more information, see {@code OVERVIEW.html}.</li>
+ <li>Changed ndk-build script defaults to compile code with format string protection
+ {@code -Wformat -Werror=format-security}. You may set
+ {@code LOCAL_DISABLE_FORMAT_STRING_CHECKS=true} to disable it.
+ For more information, see {@code ANDROID-MK.html}</li>
+ <li>Added STL pretty-print support in {@code ndk-gdb-py}. For more information, see
+ {@code NDK-GDB.html}.</li>
+ <li>Added tests based on the googletest frameworks.</li>
+ <li>Added a notification to the toolchain build script that warns you if the current shell
+ is not {@code bash}.</li>
