Hi I am trying to compile scipy svn (r1676) with gcc 4.1. One of gfortran's developers suggested me to use gcc 4.1 instead of 4.0.2 because this release is supposed to be much more stable and fast. After building numpy successfully, also from svn, the scipy compilation fails when tries to build the dfftpack library. It seems that distutils fails to find the fortran compiler. I'm a bit perplexed about this because it has been able to build all the previous fortran subpackages... ... customize IntelFCompiler customize LaheyFCompiler customize PGroupFCompiler customize AbsoftFCompiler customize NAGFCompiler customize VastFCompiler customize GnuFCompiler customize CompaqFCompiler customize IntelItaniumFCompiler customize Gnu95FCompiler customize G95FCompiler customize GnuFCompiler customize Gnu95FCompiler customize GnuFCompiler customize GnuFCompiler using build_clib building 'dfftpack' library compiling Fortran sources f77(f77) options: '-Wall -fno-second-underscore -fPIC -O2 -funroll-loops -fomit-frame-pointer -malign-double' compile options: '-c' f77:f77: Lib/fftpack/dfftpack/dcost.f sh: f77: command not found sh: f77: command not found error: Command "f77 -Wall -fno-second-underscore -fPIC -O2 -funroll-loops -fomit-frame-pointer -malign-double -c -c Lib/fftpack/dfftpack/dcost.f -o build/temp.linux-i686-2.4/Lib/fftpack/dfftpack/dcost.o" failed with exit status 127 I am not specially interested in building scipy with gcc 4.1 but I thought that the resoults would have some interest. guillem -- Guillem Borrell Nogueras WEBSITE http://torroja.dmt.upm.es:9673/Guillem_Site/ BLOG http://torroja.dmt.upm.es:9673/Guillem_Borrell/ EMAIL guillemborrell_at_gmail.com (personal) guillem_at_torroja.dmt.upm.es (CFD Lab.
