Make boost build

[dmc]

We need to get boost libraries (​http://www.boost.org/) built for Android. Some start information on how to do that can be found there: ​http://groups.google.com/group/boost-list/browse_thread/thread/ce2144a2ee9e47f9/f75844dc37f8fd4c

user-config.jam for building

[alan]

I have had some success building boost 1.39 with the attached user-config.jam. I am running bjam with the following command:

bjam --without-python --without-math --without-mpi --without-iostreams toolset=gcc-android4.4.0 link=static runtime-link=static target-os=linux --stagedir=android stage

patch for boost 1.39

[alan]

I havent tried running the boost unit tests but have run unit tests for my application which is using boost

[pelya]

​https://github.com/MysticTreeGames/Boost-for-Android - Boost 1.45, compiles without any issues with official NDK r5c, however to use boost::spirit you'll need wide chars support and CrystaX NDK r5.

[dmc]

Thanks, I know this project. It's good and I got some ideas from there. However, it's not enough to get boost compiled; unit/regression tests must be passed too and this is the main problem as of now. There is many parts where boost unit tests failed on android. My goal is to fix such places and release fully working boost distribution for android.

[ybereza]

Could you tell me which of boost libreries does not pass unit/regression tests?

Milestone r6-crystax-3 deleted

This is how I got boost to build, using Google NDK r7,

Compiler
Map the active NDK compiler to Google, using junction or ln

Windows –
junction c:\android-ndk c:\android-ndk-google

Mac OS –
ln –s /android-ndk /android-ndk-google

WCHAR_T

Edit /android-ndk-google/sources/cxx-stl/gnu-libstdc++/include/string
Add the following code to the end of the file,

#if defined(ANDROID)
namespace std
{

typedef long unsigned int wint_t;
typedef basic_string<wchar_t> wstring;

inline int iswspace(wint_t c) { return ::iswspace(c); }
inline int iswpunct(wint_t c) { return ::iswpunct(c); }
inline int iswprint(wint_t c) { return ::iswprint(c); }
inline int iswcntrl(wint_t c) { return ::iswcntrl(c); }
inline int iswupper(wint_t c) { return ::iswupper(c); }
inline int iswlower(wint_t c) { return ::iswlower(c); }
inline int iswalpha(wint_t c) { return ::iswalpha(c); }
inline int iswdigit(wint_t c) { return ::iswdigit(c); }
inline int iswxdigit(wint_t c) { return ::iswxdigit(c); }
inline int towlower(wint_t c) { return ::towlower(c); }
inline int towupper(wint_t c) { return ::towupper(c); }
inline size_t wcslen(const wchar_t *c) { return ::wcslen(c); }

inline size_t wcsxfrm(wchar_t* ws1, const wchar_t* ws2, size_t n) { return ::wcsxfrm(ws1, ws2, n); }
inline long int wcstol(const wchar_t* nptr, wchar_t endptr, int len) { return ::wcstol(nptr, endptr, len); }
inline wchar_t* wcscpy(wchar_t* dest, const wchar_t* src) { return ::wcscpy(dest, src); }
inline int wcscmp(const wchar_t* dest, const wchar_t* src) { return ::wcscmp(dest, src); }

}
#endif

ARMEABI-V7A Support

At the time of writing this Google made a mistake, setting the armeabi-v7a floating point compiler options to “fpvv3”, instead of “fpvv3-d16”, so search and replace all instances of “fpv” in –

• /android-ndk-google/*.mk
• /android-ndk-google/*.sh
• /android-ndk-crystax/*.mk
• /android-ndk-crystax/*.sh
