It's not really that I'm doing anything: gnulib seems to detect MSYS as being a POSIX platform. > Try configuring with --enable-threads=windows, as documented in > > https://www.gnu.org/software/gnulib/manual/html_node/Gnulib-multithreading.html > > If that works fine and you want to make it the default, add an invocation > of > gl_AVOID_WINPTHREAD to your configure.ac file. > Thanks very much for the hints. In the end I tried something a bit different, which was to reduce the number of gnulib modules I was using, as for the code I'm writing it seemed reasonable to assume C99 and POSIX.1-2008. I ran into another minor problem while doing this. My module list was: bootstrap filenamecat-lgpl getline getopt-gnu manywarnings pathmax relocatable-lib-lgpl relocatable-script strcase On Windows, I got a link error when linking against libgnu, as the dependencies of the modules above cause gnulib's stdlib.h to be installed, and on Windows, rpl_free is defined, but free.c was not compiled into libgnu. Adding the free-posix module fixed my problem, which looks therefore like a missing dependency. -- https://rrt.sc3d.org
