在Mac OS X Lion 下编译Android 源码出现的一个问题
出错原因：
./external/elfutils/config-compat-darwin.h:42: error: static declaration of ‘strnlen’ follows non-static declaration
/usr/include/string.h:143: error: previous declaration of ‘strnlen’ was here
make: *** Error 1
解决方案：参考别人些的文章
http://blog.sephiroth.it/2011/10/17/compiling-android-source-on-mac-lion/
modify ./external/elfutils/config-compat-darwin.h.
replace:
static inline size_t strnlen (const char *__string, size_t __maxlen)
{
int len = 0;
while (__maxlen-- && *__string++)
len++;
return len;
}
with:
#if 0
static inline size_t strnlen (const char *__string, size_t __maxlen)
{
int len = 0;
while (__maxlen-- && *__string++)
len++;
return len;
}
#endif
Well, at the end of the process I just edited the Android.mk makefile into external/skia adding a new entry for BUILD_STATIC_LIBRARY and the next command was simply:
mmm external/skia
which produced the required libskia.a file to be linked in my project.
第二个问题：
warning: ignoring file out/host/darwin-x86/obj/STATIC_LIBRARIES/
libSDL_intermediates/libSDL.a, file was built for archive which is not
the architecture being linked (i386)
Undefined symbols for architecture i386:
Do this by commenting out all lines in
external/qemu/Android.mk
The toolchain problem stems from the fact that Android actually supports the mac toolchain from Snow Leopard and onwards. So put homebrew path LAST in $PATH, so that it uses the Mac toolchain first.
When building DevNull/Oxygen ROM you in addition to the steps above also need to make a symlink in /usr/local/bin from sed to gsed, since they explicitly call gsed at one point. Also you have to disable WITH_DEXPREOPT like so:
make -j8 ［devnull］ WITH_DEXPREOPT=false
