Hi, So this Mandriva guy tells me gfortran can't compile Scilab, and he is right! Scilab is a pretty important piece of Fortran that many people use, so it is a shame that gfortran can't build it right now. But the reason why it can't is not really a Fortran problem (at least I haven't found any yet ;-) but a compatibility problem with the library wrt. what g77 had (libU77?)...
Scilab uses some kind of C <-> Fortran compatiblity layer where they have a getarg.c that calls C2F(getarg), with a line in one of the included header files that says "#define C2F(name) name##_". The same thing happens with iargc, so the gerarg.o object that the linker sees ends up calling getarg_ and iargc_. This worked Just Fine with g77, and apparently it works with g95 as well. It does not work with gfortran, because we have instead gfortran_getarg_i4 and so on. I'm looking for suggestions for how to fix this in libgfortran. I would fix this in Scilab, except that if gfortran is to be a drop-in replacement for g77, then we shouldn't have this kind of rather silly compatibilty issues. Thoughts? Gr. Steven
