Hello,
Last weekend a friend and I were trying to build double-precision vanilla Pd (Pd-double) with MinGW. After many troubles not to mention here I remembered about makefile.mingw which is in the src/ dir of the distributions. This gave us a build of Pd-double. But it could not start because of missing standard c or cpp libs. I had seen that before when compiling [soundtouch~] with MinGW. There's flags -static-libgcc and -static-libstdc++, or you can include .dll's. Anyhow, I did 'make -f makefile.mingw clean' and compiled again, but now suddenly missing files.... Those files must have been there while the first build succeeded, no? I'll give it another try soon.
