It's been a while since I installed MinGW-w64 so I can't remember the
specific installation options selected (thread models, etc), or if that
is relevant.
I've been able to compile a few relatively simple C and C++ programs.
Using the MSYS2/MINGW64 shell for program compilation. Installed boost
for using pacman under the MSYS2 shell (not MINGW32 or MINGW64).
pacman -Ss | grep boost
mingw32/mingw-w64-i686-boost 1.63.0-1 [installed]
mingw64/mingw-w64-x86_64-boost 1.63.0-1 [installed]
I'm able to compile and run a "simple" boost example (simple.cpp.txt [1]
attached) without errors using:
g++ simple.cpp -o simple
However, when trying to compile the program_options "first" example
(po_first.cpp.txt attached), I get a lot of errors (po_first.log.txt).
g++ po_first.cpp -o po_first
I don't know if I set up MinGW-w64 correctly, or if I need to specify
includes or libraries to link to on g++ command line. Any tips appreciated.
