A packaging error put a 64-bit version + of the {@code awk} executable under {@code prebuilt/linux-x86/bin} in NDK r7.</li> + <li>Fixed native Windows build ({@code ndk-build.cmd}).

The fixes include: + <ul> + <li>Removed an infinite loop / stack overflow bug that happened when trying + to call {@code ndk-build.cmd} from a directory that was <em>not</em> the top of + your project path (e.g., in any sub-directory of it).</li> + <li>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.</li> + <li>Fixed a problem where special characters in files or paths, other than spaces and + quotes, were not correctly handled.</li> + </ul> + </li> + <li>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. + + <p>See {@code docs/STANDALONE-TOOLCHAIN.html} for more details about this fix.</p> + </li> + <li>Fixed {@code gnustl_shared} on Cygwin.

(recommended)</li> + <li>Define {@code APP_GNUSTL_FORCE_CPP_FEATURES} to {@code 'exceptions'}, + {@code 'rtti'} or both in your {@code Application.mk}.

It debugs the main application process, instead of the + first process listed by {@code ps}, which is usually a service process.</li> + <li>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.</li> + <li>{@code stlport}: Refresh the sources to match the Android platform version. This + update fixes a few minor bugs: + <ul> + <li>Fixed instantiation of an incomplete type</li> + <li>Fixed minor "==" versus "=" typo</li> + <li>Used {@code memmove} instead of {@code memcpy} in {@code string::assign}</li> + <li>Added better handling of {@code IsNANorINF}, {@code IsINF}, {@code IsNegNAN}, + etc.</li> + </ul> + <p>For complete details, see the commit log.</p> + </li> + <li>{@code stlport}: Removed 5 unnecessary static initializers from the library.</li> + <li>The GNU libstdc++ libraries for armeabi-v7a were mistakenly compiled for + armeabi instead.
