SSE4

@ArekPiekarz I've tried to follow your steps, but got different error: ``` boost_python/1.66.0@bincrafters/testing: WARN: Trying to remove corrupted source folder boost_python/1.66.0@bincrafters/testing: WARN: This can take a while for big packages...

okay, this one was trivial - MSYS2 has updated to python 3.7, so I've edited your **conanfile.txt**: ``` cat > conanfile.txt [requires] boost_python/1.66.0@bincrafters/testing [options] python_dev_config:python=python3 boost_python:python_version=3.6 [generators] cmake ``` after...

found a fix, will try to apply it: https://github.com/boostorg/python/commit/660487c43fde76f3e64f1cb2e644500da92fe582#diff-467cabb22a6c637452d730accca26d2e

after applying the patch, the error is: ``` gcc.link.dll bin\python\build\540357c0269b1fe8294ca49f2ddb13be\libboost_python3.dll.a C:/msys64_conan/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lpython37 collect2.exe: error: ld returned 1 exit status "g++" -L"C:\MSYS64~1\mingw64\lib" -Wl,-rpath -Wl,"/C:/msys64_conan/mingw64" -Wl,-rpath -Wl,"/C:/msys64_conan/mingw64/lib" "-Wl,--out-implib,bin\python\build\540357c0269b1fe8294ca49f2ddb13be\libboost_python3.dll.a" -o "bin\python\build\540357c0269b1fe8294ca49f2ddb13be\libboost_python3.dll"...

okay, now issue seems to be completely clean: boost generator sets python library directory (**-L** option), but doesn't override python library name for some reason - it's just ignored for...

@grafikrobot do you have an idea how to specify python library name for boost? according to the https://www.boost.org/doc/libs/1_68_0/libs/python/doc/html/building/configuring_boost_build.html, 3rd parameter must be `the path to Python library binaries`. however, you...

@solvingj nope, I was able to get it working with boost package (non-modular one), I just need to merge my changes

reproduced with latest build (1.69.0): ``` gcc.link.dll bin/python/build/91f4860ef2a4c64e13a521917e650b61/libboost_python36.dll.a /usr/lib/gcc/x86_64-pc-msys/6.4.0/../../../../x86_64-pc-msys/bin/ld: cannot find -lpython3.6 collect2: error: ld returned 1 exit status "/usr/bin/g++" -L"/usr/lib" -Wl,-rpath -Wl,"/usr/lib" "-Wl,--out-implib,bin/python/build/91f4860ef2a4c64e13a521917e650b61/libboost_python36.dll.a" -o "bin/python/build/91f4860ef2a4c64e13a521917e650b61/libboost_python36.dll" -Wl,-h -Wl,libboost_python36.dll -shared -Wl,--start-group...

@ArekPiekarz I was able to fix the issue, fixes are in `1.69.0` branch (testing/stable), please give an another try

weird, it have successfully found python library: ``` D:/dev/app/msys64/mingw64/lib/libpython3.7m.dll.a ``` but tries to link with `-lpython37` for some reason. the path look a bit weird for MSYS, but I think...
