I've decided to try building Mercury from the "release of the day" source on MinGW-w64 via MSYS2. I am using the MinGW-w64 version of GCC. Unfortunately, this approach has problems of its own. When I run $ ./configure --host=x86_64-w64-mingw32 --with-cc=gcc --enable-minimal-install I get a warning: checking return values of system... no configure: WARNING: Unable to interpret return values from system The script does successfully terminate; however, when I run make it usually fails. I have included the output of ./configure in a text file. From what I can gather, either I am missing some libraries that allows C to communicate with the terminal, or those commands are not making it to MSYS2. Any suggestions? Best wishes, Noah G. P.S. Once again, thank you all so much for taking the time out to help me. </body> </html>
