[SOLVED] LFS project help

Toroso · 03-22-2015, 07:11 AM

I'm using LFS 7.7 to build a Linux system. I'm having issues getting the GCC to compile successfully on pass 1. Would love to chat with others who have experience here.

Thanks!

What error messages are you getting? And in which step.

Toroso · 03-22-2015, 07:41 AM

This is at the tail end, I don't see any errors in the output but I can only go back so far in terminal.

Code:

checking whether the C compiler works... no
configure: error: in `/mnt/lfs/sources/gcc-build/gmp':
configure: error: C compiler cannot create executables
See `config.log' for more details
make[2]: *** [configure-stage2-gmp] Error 77
make[2]: Leaving directory `/mnt/lfs/sources/gcc-build'
make[1]: *** [stage2-bubble] Error 2
make[1]: Leaving directory `/mnt/lfs/sources/gcc-build'
make: *** [all] Error 2

It says here that there is a configure error in gmp. In the config.log the only error I see refers to isl
which I don't see mentioned anywhere in the LFS book.

Do you have gcc installed on your host system? See by running 'gcc -version'.

Yes, 4.8.2

Please post the output of the version.sh script a lot of these gcc/glibc/binutils erros are because of a non complient host.

What is your host system by the way.

As produced in error output, you should see config.log file. It is little difficult to understand it at start/newbie.

hi

You have built LFS already and it is a good base to build another. You know lfs will build I would go back and remove all and start again that was mentioned in the other thread as well.

Generally this can be source of problem while building LFS. Try replacing dash with bash for sh symlink.

veerain · 03-23-2015, 05:19 AM

Also make dummy c file and compile with gcc to see if it works.

Code:

echo "int main () { return 0; }" > test.c
gcc -o test test.c
./test
echo $?

Also reading the exact error by looking at config.log file generated by configure command.

OK, I'm not familiar with that at all. Can you provide more info?

Thanks

I've done that as part of the LFS guide and it did not work.

It says there is an issue with gmp configure, but there is no config.log in the gmp directory.

Have you fixed the dash symlink issue?
what chapter are you on?

I'm a Linux n00b, not quite sure how to do that.

At work now...

I'm on chapter 5 of LFS 7.7. Just running pass1 on GCC.
