I'm in the process of migrating a C++ application from VC++ to GCC (running on Windows using Cygwin). My first problem now is that I cannot build the Boost libraries.
For example to build Boost.Exception with VC++ I would write:
b2 --with-exception variant=debug,release link=static runtime-link=static
and I would get the files libboost_exception-vc100-mt-s-1_51.lib and libboost_exception-vc100-mt-sgd-1_51.lib in my stage\lib directory.
However when I try the same using GCC form a Cygwin terminal I get errors. I found out that building only debug (or only release) like this works:
./b2 --with-exception variant=debug link=static runtime-link=static
It creates libboost_exception.a in my stage\lib directory for both cases (debug and release). So there seems to be a name conflict (same name for debug and release variant). Is this a bug in the boost build system or am I doing something wrong?
Edit:
The output of
./b2 --with-exception variant=debug,release link=static runtime-link=static
is:
