Hello,
I am having a new problem when attempting to install apps from source. Installing ebuilds is working fine, but when installing tarballs I get the following error when running the configure script:

Code:

checking whether the C compiler (gcc  ) works... no
configure: error: installation or configuration problem: C compiler
cannot create executables.


It's probably something simple, but I have never had this before.

Anyone?

Hrmm.. strange that searching the forums I came up with a bunch of unrelated stuff, but did not find that thead ;(

..anyway my CFLAGS from make.conf:
CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"

They are as I have had them set for a while now. I need to change them?

your flags are fine, but your the CFLAGS environment variable must have gotten screwed up somehow do this:

Code:
sh /etc/make.conf

Installing ebuilds is working fine, but when installing tarballs...

Are you stating that emerging ebuilds work, but if you try to compile anything else it does not, right?

If you are not using an ebuild, the flags in /etc/make.conf do not get read. Therefore, they shouldn't be the problem.

try to compile the following code (save it as test.c):
Code:

#include <stdio.h>
void main(){
     printf("Hello world\n");
}


Use the following command line to do so
Code:

gcc test.c -o test
./test


to see if it works.

EDIT Almost forgot it, moving to Portage & Programming.

Well that one I forgot to ask, are you using gcc-3.2.1-rc6?

Yes, gcc-3.2.1-r6.
and for the test:
Code:

# /usr/i686-pc-linux-gnu/gcc-bin/3.2/gcc test.c -o test
test.c: In function `main':
test.c:2: warning: return type of `main' is not `int'
# ./test
Hello world


Hrmm... was there a link to gcc in my path that is no longer installed?

I'll tell you the same thing I've told to rommel:

Quote:

Yes, I've read here and there that this version may cause some problems and it is more a version for developers (it even puts an advisory about it when you emerge it).

I am running gcc-3.2.1 without problems, may I suggest you to try it? Maybe you'll need to download a tarball and copy the binaries of gcc if you aren't able to emerge it using your current version.


His thread is here.
