1 Hi all,
2
3 GCC 4.1 will be unmasked this week. A major consequence for scientific
4 users is the switch from g77 to gfortran.
5
6 Things you can do to help make the switch easier for everyone:
7
8 Developers: Check all your Fortran packages to ensure they work with
9 gfortran from sys-devel/gcc-4.1.1_pre20060517. If they're C/C++, it's
10 also worth testing your packages because GCC 4 is tougher on compliance
11 than GCC 3.
12
13 Users/Testers: Unmask and install GCC 4.1 with `echo
14 "=sys-devel/gcc-4.1*" >> /etc/portage/package.unmask` and `emerge gcc`.
15 Switch to it with gcc-config (Use `gcc-config -l` to list available
16 compilers). Install portage-utils and run `emerge --oneshot $(qlist -I
17 -C sci*/)`. This will reinstall all your sci-* packages using your new gcc.
18
19
20 When you come across a broken package, file a bug for it.
21
22 Packages I know don't work:
23 {blas,cblas,lapack}-reference -- I have patches for these
24 apbs
25 numarray
26
27 Thanks,
28 Donnie
