Hello, I'm interested in fiddling with YHC, maybe helping out from time to time whenever I get free time, so I tried to install it from darcs today. Everything went well (got the source from darcs, downloaded SCons) until I did the configure script (error below). The scons output tells me that it can't find a C compiler. I have one on this computer via MinGW (which has executables named "gcc.exe" and "cpp.exe"). Not knowing SCons, I still took a shot in the dark at the configure script, changing the 'env' line to: env = Environment(ENV=os.environ, CPPPATH=["#.", "C:\\MinGW\\bin\\"]) but that didn't work, either. Should I go with an entirely different compiler? I don't remember why I installed that one, but I'm not sure I even used it, so I'm not even sure if it works. I guess I'm mostly appealing to the last line of the output below, "If so then please contact the Yhc developers for help." (smile) Any help would be appreciated!
