+ Android NDK, Revision 7b (February 2012)
+
+
+
+This release of the NDK includes fixes for native Windows builds, Cygwin and many other + improvements:
+ +-
+
- Important bug fixes: + +
-
+
-
+
- Updated {@code sys/atomics.h} to avoid correctness issues + on some multi-core ARM-based devices. Rebuild your unmodified sources with this + version of the NDK and this problem should be completely eliminated. + For more details, read {@code docs/ANDROID-ATOMICS.html}. +
- Reverted to {@code binutils} 2.19 to fix debugging issues that + appeared in NDK r7 (which switched to {@code binutils} 2.20.1). +
- Fixed {@code ndk-build} on 32-bit Linux. A packaging error put a 64-bit version + of the {@code awk} executable under {@code prebuilt/linux-x86/bin} in NDK r7. +
- Fixed native Windows build ({@code ndk-build.cmd}). Other build modes were not
+ affected. The fixes include:
+
-
+
- Removed an infinite loop / stack overflow bug that happened when trying + to call {@code ndk-build.cmd} from a directory that was not the top of + your project path (e.g., in any sub-directory of it). +
- Fixed a problem where the auto-generated dependency files were ignored. This + meant that updating a header didn't trigger recompilation of sources that included + it. +
- Fixed a problem where special characters in files or paths, other than spaces and + quotes, were not correctly handled. +
+ - Fixed the standalone toolchain to generate proper binaries when using
+ {@code -lstdc++} (i.e., linking against the GNU {@code libstdc++} C++ runtime). You
+ should use {@code -lgnustl_shared} if you want to link against the shared library
+ version or {@code -lstdc++} for the static version.
+
+
See {@code docs/STANDALONE-TOOLCHAIN.html} for more details about this fix.
+
+ - Fixed {@code gnustl_shared} on Cygwin. The linker complained that it couldn't find + {@code libsupc++.a} even though the file was at the right location. +
- Fixed Cygwin C++ link when not using any specific C++ runtime through + {@code APP_STL}. +
+
-
+
- Other changes: + +
-
+
-
+
- When your application uses the GNU {@code libstdc++} runtime, the compiler will
+ no longer forcibly enable exceptions and RTTI. This change results in smaller code.
+
If you need these features, you must do one of the following:
+-
+
- Enable exceptions and/or RTTI explicitly in your modules or + {@code Application.mk}. (recommended) +
- Define {@code APP_GNUSTL_FORCE_CPP_FEATURES} to {@code 'exceptions'}, + {@code 'rtti'} or both in your {@code Application.mk}. See + {@code docs/APPLICATION-MK.html} for more details. +
+ - {@code ndk-gdb} now works properly when your application has private services + running in independent processes. It debugs the main application process, instead of the + first process listed by {@code ps}, which is usually a service process. +
- Fixed a rare bug where NDK r7 would fail to honor the {@code LOCAL_ARM_MODE} value + and always compile certain source files (but not all) to 32-bit instructions. +
- {@code stlport}: Refresh the sources to match the Android platform version. This
+ update fixes a few minor bugs:
+
-
+
- Fixed instantiation of an incomplete type +
- Fixed minor "==" versus "=" typo +
- Used {@code memmove} instead of {@code memcpy} in {@code string::assign} +
- Added better handling of {@code IsNANorINF}, {@code IsINF}, {@code IsNegNAN}, + etc. +
For complete details, see the commit log.
+
+ - {@code stlport}: Removed 5 unnecessary static initializers from the library. +
- The GNU libstdc++ libraries for armeabi-v7a were mistakenly compiled for + armeabi instead. This change had no impact on correctness, but using the right + ABI should provide slightly better performance. +
- The {@code cpu-features} helper library was updated to report three optional + x86 CPU features ({@code SSSE3}, {@code MOVBE} and {@code POPCNT}). See + {@code docs/CPU-FEATURES.html} for more details. +
- {@code docs/NDK-BUILD.html} was updated to mention {@code NDK_APPLICATION_MK} instead + of {@code NDK_APP_APPLICATION_MK} to select a custom {@code Application.mk} file. +
- Cygwin: {@code ndk-build} no longer creates an empty "NUL" file in the current + directory when invoked. +
- Cygwin: Added better automatic dependency detection. In the previous version, it
+ didn't work properly in the following cases:
+
-
+
- When the Cygwin drive prefix was not {@code /cygdrive}. +
- When using drive-less mounts, for example, when Cygwin would translate + {@code /home} to {@code \\server\subdir} instead of {@code C:\Some\Dir}. +
+ - Cygwin: {@code ndk-build} does not try to use the native Windows tools under + {@code $NDK/prebuilt/windows/bin} with certain versions of Cygwin and/or GNU Make. +
+ - When your application uses the GNU {@code libstdc++} runtime, the compiler will
+ no longer forcibly enable exceptions and RTTI. This change results in smaller code.
