I try to compile the 3.9.44 Atlas with LAPack (full LAPack) under Windows. The build under Cygwin works (32 Bit, shared libs). Now I would try to to build Atlas without the Cygwin library and Visual Studio interface. I set the options "-Si nocygwin 1 -C ic cl". The configure show the error:
gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler.
I have installed the mingw compilers (gcc, g++, gfortran) under Cygwin and try to setup the --host, --build or --target to the configure but I can't tell the configure to use the mingw compiler. How can I tell the configure script to use the mingw compiler toolset? I hope that my question is not off topic.
