[SOLVED] Meaning of "-gcc"

michanux · 04-06-2015, 05:14 AM

Hello
second pass of "binutils" failed at LFS book
http://www.linuxfromscratch.org/lfs/...ils-pass2.html
"configure" breaks with the issue

Code:

checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln works... yes
checking whether ln -s works... yes
checking for a sed that does not truncate output... /bin/sed
checking for gawk... gawk
checking for gcc... -gcc
checking for C compiler default output file name... 
configure: error: in `/mnt/lfs/sources/binutils-build':
configure: error: C compiler cannot create executables
See `config.log' for more details.

config.log

Code:

configure:3981: checking for gcc
configure:4008: result: -gcc
configure:4237: checking for C compiler version

| /* end confdefs.h.  */

A "/mnt/lfs/tools/bin/i686-lfs-linux-gnu-gcc" is present. Does "configure" looking for this "-gcc"?

The gcc compiler has not been found.

Why?

Hi

post the output of version check script to start with

If you carefully examine the configure command used by binutils pass 2, you can notice the following line:

CC=$LFS_TGT-gcc

If for some reason $LFS_TGT is empty (and it is in your case), the CC variable would just be set to -gcc, which is why you see that. Check your environment.

Yes the variable $LFS_TGT was empty. After a reboot the compiler worked fine. I had checked $LFS_TGT before I started the new compiling process. Thank You.
