Description Pierre Blavy 2012-10-25 14:48:37 UTC 
Description of problem:
When using the mingw version of boost libraries, linking with -lboost_xxx do not work.

How reproducible: always


Steps to Reproduce:
1. install mingw-boost
2. make a C++ program, link it with boost, compile with mingw
 i686-w64-mingw32-g++ main.cpp -o /tmp/test -l boost_regex
  
Actual results:

Linking fail
ld: cannot find -lboost_regex

but lib exists
find /usr/i686-w64-mingw32 | grep boost_regex
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-mt-1_48.dll.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-mt-d-1_48.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-d-1_48.dll.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-mt-1_48.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-mt-d-1_48.dll.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-d-1_48.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-1_48.a
/usr/i686-w64-mingw32/sys-root/mingw/lib/libboost_regex-gcc47-1_48.dll.a
/usr/i686-w64-mingw32/sys-root/mingw/bin/boost_regex-gcc47-1_48.dll
/usr/i686-w64-mingw32/sys-root/mingw/bin/boost_regex-gcc47-mt-1_48.dll
/usr/i686-w64-mingw32/sys-root/mingw/bin/boost_regex-gcc47-mt-d-1_48.dll
/usr/i686-w64-mingw32/sys-root/mingw/bin/boost_regex-gcc47-d-1_48.dll


Expected results: linker should link with the last working boost lib.
Maybe a symlink pointing to it is missing.


Additional info:
Workaround : link with -lboost_regex-gcc47-1_48
