Re: [Mingw-cross-env-list] cmake unable to find boost_thread

[Brad Pitcher]

Well, the libs are located in ...
/mingw-cross-env/usr/i686-pc-mingw32/lib/libboost*
Specifically, boost_thread is named libboost_thread_win32-mt.a

Maybe cmake looks for a different name with different conventions. You
may try to create a symlink to this file and name it
libboost_thread-mt.a, or libboost_thread.a. Also, cmake may be looking
for a shared lib, as libboost_thread is usually linked as shared.

If you link to the boost_thread static lib in mingw-cross-env, you'll
have to define -DBOOST_THREAD_USE_LIB while building your app.
Otherwise, thread local storage cleanup may cause linker errors or
even runtime problems.

Good call! All I had to do was set _boost_COMPILER to "_win32" and add the following pattern to the checked patterns:
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_COMPILER}${_boost_MULTITHREADED}

Now I have another issue to debug:
[ 33%] Building CXX object src/CGAL/CMakeFiles/CGAL.dir/all_files.cpp.obj
In file included from /home/brad/Downloads/CGAL-3.8/src/CGAL/assertions.cpp:24:0,
                 from /home/brad/Downloads/CGAL-3.8/src/CGAL/all_files.cpp:20:

make[1]: *** [src/CGAL/CMakeFiles/CGAL.dir/all] Error 2

make: *** [all] Error 2

Fortunately, a web search reveals a plethora of other folks with the issue although I'd doubt if any of them are using mingw-cross-env. I will begin to wade through the results, but if you've seen this before or have any ideas, please speak up.

Thanks,
Brad
