GCC Final Pass Error...

LinuxNoob75 · 07-30-2007, 02:36 PM

Hello.
-I'm now using the LFS LiveCD from about a month ago, along with the book and sources that came with it.
-I haven't received any other error messages to boot, and have followed the LFS book closely.
-I'm installing LFS 6.2 on a x86 Dell XPS. I have to configure X when I run it on the Live CD using the method on the CD's documentation.
-When I've installed all packages up to GCC- final pass(6.12.1), I've copied the package's source directory in $LFS/sources(where I originally had extracted all the sources files), and pasted the directory into $LFS.(or in to $LFS/package-build when necessary). I've then cd'ed into the copied directory, followed the instructions for the package, completed it successfully, and then gone to $LFS and deleted the copied directory. When installing the package for the second time, I'd copy the directory from sources and do it all over again. I executed every command, without any errors at all.
Until I got to GCC- 6.12.1 I copy the GCC-4.0.3 directory from sources into $LFS/gcc-build, run the sed commands successfully, prepare GCC for compilation, and then the make gives me this error:
Note: I only copied the important sections.

Code:

Warning: "Flex" is missing on your system. You should only need it if you modified a '.l' file. You may need the 'Flex' package in order for these modifications to take effect.........

Later:

Code:

gcc:gengtype-lex.l:No such file or directory
gcc: no input files
make[1] ***[build/gengtype-lex.o] Error 1
make[1] Leaving Directory '/gcc-build/gcc-4.0.3'
make ***[all-gcc] Error 2

What could be wrong?

Should I get and install this flex package?

should I be installing gcc-4.3.0 in gcc-build in /?(of the chroot enviorment)

Hi,

I personally think that you are doing it (copy/paste directories) the hard way.

Put all packages into $LFS/sources

Unpack/untar the package you need:

tar jxf package-1.1.2.tar.bz2 (or tar zxf package-4.3.2.tar.gz or ..... )
cd package-1.2.3

The above 2 steps are assumed by LFS.
Most of the time the commands given in the book are based on where you are standing now, in this case that would be: $LFS/sources/package-1.2.3

For most of the chapters all is done from here, but for some (gcc being one of those) it is needed to create a building dir (the source directory they talk about is the directory you are in at the moment). You do that as follows:

mkdir -v ../package-1.2.3-build
cd ../package-1.2.3-build

Now you are in the freshly created, empty directory ($LFS/sources/package-1.2.3-build), the actual files should still be in $LFS/sources/package-1.2.3 (!)

If you copied all the files into the build directory you are probably in trouble. The first time you had to use a build directory was in chapter 5 (5.3. Binutils)........ This is one of those moments I'm hoping I misunderstood you

Anyway, hope this helps.

OK. I re did my LFS as you said, and no errors. HOWEVER I DIDN'T run any un-mandatory test suites.
Now, at the same make command of gcc's final pass, I get:

Code:

In file included from /sources/gcc-build/gcc/include/syslimits.h:7,
                 from /sources/gcc-build/gcc/include/limits.h:11,
                 from ../../gcc-4.0.3/gcc/tsystem.h:108,
                 from ../../gcc-4.0.3/gcc/crtstuff.c:64:
/sources/gcc-build/gcc/include/limits.h:122:61: error: limits.h: No such file or directory
In file included from ../../gcc-4.0.3/gcc/crtstuff.c:64:

make[1]: *** [crtbegin.o] Error 1
make[1]: Leaving directory `/sources/gcc-build/gcc'
make: *** [all-gcc] Error 2

And my testsuite summaries are:

Code:

 === gcc Summary ===

# of expected passes            21685
# of unexpected failures        6943
# of unexpected successes       2
# of expected failures          67
# of unresolved testcases       6349
# of untested testcases         42
# of unsupported tests          339
/sources/gcc-build/gcc/xgcc  version 4.0.3

Finally, I would like to add that after every successful package that needs a build directory I delete the build directory. However, I don't delete the un-zipped source directory, and use that same one for the next installation of that package.(Hence I only un-zip each package once, which was before I started building my LFS, as a different user)
What could be wrong?

Hi,

And the answer is in the LFS book:

Quote:

Important

After installing each package, delete its source and build directories, unless specifically instructed otherwise. Deleting the sources prevents mis-configuration when the same package is reinstalled later.

Here's the link to that quote.

The problem you describe (error: time.h: No such file or directory) could be related to not removing the directories. It could also point to other problems, although I doubt it.

But that is water under the bridge, if you did not remove the directories after build/install, you do need to start over again. If you are lucky you probably need to redo from the beginning of chapter 6, but I really don't know if removing the build dirs in chapter 5 was enough (and the warning in the LFS book is there for a reason.....).

Hope this helps.
