12570,"b2 ignores Iconv and disabled boost-locale lib, even though has_iconv.cpp passed",hbadger@…,Artyom Beilis,"Building boost from sources git tag 1.62.0 (4f2bdeb93a4be13ba0dc5e9f44920a2bf67191fc)
I want to crossbuild it, on linux (ubuntu) host, for Mac OS X target.

Goal:
crossbuild the lib boost, with boost-locale

Result: boost says that locale needs either ICU or iconv, and it does not build library for locale.

Expected result: it would build the library for boost locale.

Error messages:

...
    - iconv (libc)             : no
    - iconv (separate)         : no
...
- Boost.Locale needs either iconv or ICU library to be built.
...
ls stage/lib/

Environment:

Crosscompiler and it's toolchain is built in /home/ubuntu/build/osxcross/target/bin/ and is proven to work (builds Mach-O executables, they work when copied ontop real Mac OS X).

Mac SDK is available in /home/ubuntu/build/macsdk/MacOSX10.11.sdk/
And it provides the iconv.h file ('''though I do not see any .a''' or other file for it - is that ok?)

find /home/ubuntu/build/macsdk/MacOSX10.11.sdk/usr/include | grep iconv
/home/ubuntu/build/macsdk/MacOSX10.11.sdk/usr/include/iconv.h


Executed command (in place where I downloaded boost, with needed submodules)

export WITH_ICONV=""/home/ubuntu/build/macsdk/MacOSX10.11.sdk/usr/"" &&  git clean -xdf ; git submodule foreach git clean -xdf; ./bootstrap.sh --with-icu &&   ./b2 headers  && export OSX_CPU_ARCH=""core2"" && export OSX_VERSION_MIN=""10.8"" &&  time   ./b2  --toolset=clang     --build-type=complete       --with-filesystem --with-system --with-program_options --with-thread --with-locale    cxxflags=-mmacosx-version-min=${OSX_VERSION_MIN} cxxflags=-march=${OSX_CPU_ARCH} target-os=darwin architecture=x86 address-model=64  --layout=tagged  link=static runtime-link=static  -sNO_BZIP2=1 --sNO_ZLIB=1       --prefix=/home/ubuntu/build/boost/build-osx/   threading=multi  boost.locale.icu=off boost.locale.std=off    boost.locale.iconv=on    -sICONV_PATH=""$WITH_ICONV""

Running strace debug (strace b2), I can confirm that Boost does try to build the has_ionv.cpp program, and it seems to work fine. All invocations I seen return with 0 exit code.

E.g:

[pid 22980] execve(""/home/ubuntu/build/osxcross/target/bin/x86_64-apple-darwin15-clang++"", [""/home/ubuntu/build/osxcross/target/bin/x86_64-apple-darwin15-clang++"", ""-c"", ""-x"", ""c++"", ""-march=core2"", ""-mmacosx-version-min=10.8"", ""-O0"", ""-g"", ""-fno-inline"", ""-Wall"", ""-g"", ""-fPIC"", ""-m64"", ""-march=core2"", ""-mmacosx-version-min=10.8"", ""-DBOOST_ALL_NO_LIB=1"", ""-I."", ""-I/home/ubuntu/build/macsdk/MacOSX10.11.sdk/usr/include"", ""-o"", ""bin.v2/libs/locale/build/clang-linux-3.8.0/debug/target-os-darwin/has_iconv_libc_ext.o"", ""libs/locale/src/../build/has_iconv.cpp""], [/* 22 vars */]) = 0

Repeating this test manually also works, creates the .o file, and it is indeed in Mach-O format.

No idea why then it still tells me that iconv was not enabled, and as result does not build locale.


This bug disallows me from at all using Boost until fixed.
