 |
|
Hi
We have a software which apparently requires libgfortran.so.1.0.0
As far as i could find out, this used to be installed with gcc-4.1.2
But when i try to emerge gcc-4.1.2 this fails with | Code: |
/var/tmp/portage/sys-devel/gcc-4.1.2/work/gcc-4.1.2/gcc/config/i386/crtfastmath.c:1: error: bad value (native) for -march= switch
/var/tmp/portage/sys-devel/gcc-4.1.2/work/gcc-4.1.2/gcc/config/i386/crtfastmath.c:1: error: bad value (native) for -mtune= switch
|
(i have gcc-4.7.1 as active compiler)
Indeed, my make.conf contains "native" | Code: |
CFLAGS="-march=native -O2 -pipe"
CXXFLAGS="${CFLAGS}"
|
What should i use for CFLAGS to make gcc-4.1.2 compile?
After emerging gcc-4.1.2, can i go back to the original value of the CFLAGS?
Or is there another way to get libgfortran?
Thank You
Jody |

| Code: | | echo "int main() { return 0; }" |LANG=en gcc -march=native -v -Q -x c - 2>&1 | tr " " "\n" | grep -m1 "^-march" |
?

Thank You for the information.
Is there perhaps another way to get libgfortran.so.1.0.0?
