G'day all,

I am trying to complile the coreutils in chap 5.17 and have encountered 2 errors so far relating to GMP.

In the fist instance gmp.h was missing, so I copied one from the host system /tools/include directory and this fixed the problem. But now when I try to compile I get the following error:

So I run myself and get an error that it is unable to load shared library libgmp.so.10.

I did a search in /tools/ for anything GMP related and found nothing. I am guessing that nothing for GMP has installed. However in the previous 2 passes of the GCC build, we had to extract and rename the gmp tarball directory and place in the gcc-4.7.2 directory before building GCC. Should this have given the appropriate GMP libraries? The instructions don't say to build the GMP source on it's own until chapter six. I'm not really sure how to proceed now.

Any help would be greatly appreciated.

Thank you

Tyson

Hi again,

Upon reflection I came to the conclusion that maybe the GMP libraries were not supposed to install with the GCC builds, but were just placed in the directory as referrence for the actual build process. Is this correct?

Had another read of ./configure --help and found a --without-gmp option. Added this to my ./configure and compiled and it now compiles fine! Hope this information is useful to anybody in my position.

hi

gmp is included in the gcc build you dont have to change anything

Are you saying that after pass 2 of the GCC build in chapter 5, I should have the gmp libraries in /tools/lib ?

Hi

well I have never had to deviate from the book and not had any errors
Did you untar gcc cd into gcc-dir then run 1st command about
untaring mpc mprf gmp etc that part would of satisfied the gcc error

That was a bad idea, IMO. I didn't have to do that.

Had a chat with some people on #lfs-support channel today and was advised that coreutils normally builds without gmp libraries for an lfs build in chapter 5. There should be no trace of gmp after the gcc-build I was told. For some reason, probably because I didn't delete the gcc-build directoy after compiling, the coreutils configure file thinks I have gmp installed. This was confirmed in a log file. So compiling with --without-gmp would build coreutils as it should at this point.

I have gone back anyway and am rebuilding everything from the start and will this time delete each build directory after each build and see if this makes a difference. I'll let you know how it goes.

And yes spiky, I did that as the book said. The only thing I have done different from the book, as far as I can tell, was not deleting each build directory as I progressed.

Hi all,

Rebuilt and compiled from the start, this time deleting all directories as I went, and coreutils built no problems this time.

Line 493 of configure script for the original unsucessful build:

Seems to indicate what I said above.

Thanks for the help input everyone.

Hope this helps anyone silly enough not to follow the book correctly.
