numerous gcc installations
Yes, the gcc ports are used partly because the Fortran compiler was removed from the base system. (They might have been used anyway, to take advantage of the improvements in later versions of gcc. ) bsd.gcc.mk fixes the specific compiler used via the value of the WITH_FORTRAN variable in a port Makefile. This is done intentionally, as there are substantive differences between the available compilers -- the compilers are not considered to be interchangeable. The fact that some ports continued to use gfortran42, which gerald@ and maho@ deprecated in the recent round of changes, was a mistake that has been or will be corrected. If you want to use it, don't use the WITH_FORTRAN knob; or patch bsd.gcc.mk. I agree that this probably should have been mentioned in UPDATING, but they were probably too busy fixing the many small problems that arose after the changes.

Go ahead and erase the gcc-4.2 compiler - create the gcc-4.3 compiler, and everything after that will be fine. 1) What is the realtionship between this gcc and the gcc used to compile the system? 2) Do you know why this isn't noted in /usr/ports/UPDATING? Answers: 2) You make a good point. Why don't you raise this on po...@freebsd? This should be corrected. In fact, I am going to copy this to po...@freebsd. 1) I think that in most cases, the only reason why gcc is brought in is because the gcc that is in the base system does not include a fortran compiler. So any port that uses fortran (e.g. lapack, etc) has to install a fortran compiler. Having said all this, why doesn't bsd.gcc.mk first check to see if gfortran42 was already installed, and then only install gfortran43 if a fortran is needed? But I have the impression that quite a few changes have been made to bsd.gcc.mk recently, so some mistakes are understandable.

Fortunately you can find precompiled blas, scipy and numpy (pkg_add -r py-numpy works). But i was out of luck with matplotlib, which required pkg_adding gcc-42 and then compiling tons of stuff. One of them (agg, i think, requires DISPLAY to be set and accessible in the configure script !!!) hence breaks the build for matplotlib. -- Michel TALON ___ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
