LFS

E-Kami · 07-18-2012, 01:51 AM

Hello everyone.
I'm actually trying to compile GCC 4.6.2 with the source from LFS website ftp server.
Following LFS book version 7.1, I applied the patch given with the packages but I'm having some issues

.
I compiled each gmp, mpc and mpfr separately and thus, I gave their full path while running the configure command as follow:

Code:

./configure --target=$LFS_TGT --prefix=$LFS/build/gcc-build --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --disable-libquadmath --disable-target-libiberty --disable-target-zlib --enable-languages=c --without-ppl --without-cloog --with-mpfr-include=/mnt/LFS/temp/mpfr-build/include --with-mpfr-lib=/mnt/LFS/temp/mpfr-build/lib --with-gmp-include=/mnt/LFS/temp/gmp-build/include --with-gmp-lib=/mnt/LFS/temp/gmp-build/lib --with-mpc-include=/mnt/LFS/temp/mpc-build/include --with-mpc-lib=/mnt/LFS/temp/mpc-build/lib

But once I run:

Code:

make -j4

I get the following error:

Code:

checking for suffix of object files... configure: error: in `/mnt/LFS/source/gcc-4.6.2/x86_64-lfs-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1
make[1]: Leaving directory `/mnt/LFS/source/gcc-4.6.2'
make: *** [all] Error 2

I'm using gcc 4.6.3 (I know that it is not recommended but it is the default version of my host). I also tried to find the error in the config.log file but without success =/. Someone already had this problem? Someone can help me? Thanks in advance.

Hi Did u make the gcc-build dir and cd in to before running configure command. Also why deviatd from the book. Post output of version check

E-Kami · 07-18-2012, 03:26 AM

Hello,
Thanks a lot for you quick answer. The reason I deviated from the book was because the command it gave did not work:

Code:

../gcc-4.6.2/configure \
    --target=$LFS_TGT --prefix=/tools \
    --disable-nls --disable-shared --disable-multilib \
    --disable-decimal-float --disable-threads \
    --disable-libmudflap --disable-libssp \
    --disable-libgomp --disable-libquadmath \
    --disable-target-libiberty --disable-target-zlib \
    --enable-languages=c --without-ppl --without-cloog \
    --with-mpfr-include=$(pwd)/../gcc-4.6.2/mpfr/src \
    --with-mpfr-lib=$(pwd)/mpfr/src/.libs

At the end I had something like "missing mpg and/or gmp".
So as you suggested, I tried to run the configure command from the gcc-build dir without using the --prefix argument which gave me... another error:

Code:

configure: error: building out of tree but /mnt/LFS/source/gcc-4.6.2 contains host-x86_64-unknown-linux-gnu.
Use a pristine source tree when building in a separate tree

And echo $LFS_TGT give me:
x86_64-lfs-linux-gnu
So now I'm totally lost >.<.
For version check output are you meaning this?

Hi Have a look in the preface chapter host system Requirements

Note

There are frequent misunderstandings about this chapter. The procedures are the same as every other chapter
as explained earlier (Package build instructions). First extract the gcc tarball from the sources directory and
then change to the directory created. Only then should you proceed with the instructions below.

Hello E-Kami and everybody,

Of course do what you think is best, but I think it was a mistake to change the book's steps. There is nothing wrong with them. You botched something; probably during the untarring of those three packages that were missing (GMP, MPFR and MPC) and the subsequent renaming of their folders. From there, well, you went off on a wild goose chase IMO.

I would stop, back up, delete the untarred folders in your source directory, gather up the four tarballs again, and follow the book's steps without thinking about them. Put all four tarballs in your source directory. Untar gcc. Change directories to the gcc-4.6.2 directory just untarred. Start copying and pasting the book's commands into your terminal. It will work.

All of the above was meant in the kindest possible way. Feel free to completely ignore me and press on with what you are doing.

I wouldn't ignore stoat's remarks, this from your first post:

That is the earliest indication that you did something which is not in the LFS Book and the probable cause of the problems that followed.

A tip: I see you use the -j 4 option, which is fine but be careful when using this flag when running the make test/make check steps in chapter 6. A few tests fail due to this flag (some (sub)test aren't meant to be run in parallel).

E-Kami · 07-18-2012, 10:57 PM

Thanks a lot for your answers guys. But I followed the book, step by step... 3 times... and it didn't work either.
I'll try again. I hope it will work :s . I'll update this post if I get some errors again. But do you think the errors
can come from my missing packages and/or my 4.6.7 version of gcc? Thanks again

Bad news, I switched to bash, followed EXACTLY the same steps as those on the book and I still get:

It seems yes.

spiky0011 · 07-19-2012, 04:17 AM

So the error with mpfr,gmp

E-Kami · 07-19-2012, 04:24 AM

It seems to be with libgcc but... what cause the error?
