LFS 7.2 GCC First pass: undefined reference to `GNU_USER_TARGET_OS_CPP_BUILTINS'

Hi guys.

When compiling my GCC in first pass follwing the LFS book, I got this error information:

Quote:

c-family/c-cppbuiltin.o: In function `c_cpp_builtins':
/home/sumz/Downloads/sources/gcc-build/gcc/../../gcc-4.7.1/gcc/c-family/c-cppbuiltin.c:918: undefined reference to `GNU_USER_TARGET_OS_CPP_BUILTINS'

make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory `/home/sumz/Downloads/sources/gcc-build'
make: *** [all] Error 2

Here is my version-check:

Anyone has idea how to solve this problem?

Although your version-check output looks OK, I do see something that doesn't look right:

/home/sumz/Downloads/sources/gcc-build/gcc/../../gcc-4.7.1/gcc/c-family/c-cppbuiltin.c:918: undefined reference to `GNU_USER_TARGET_OS_CPP_BUILTINS'

Why are you building in /home/sumz/Downloads and not /mnt/lfs? It also looks liike you are doing this as user sumz and not as user lfs.

You might want to re-read 1.1. How to Build an LFS System and 2. Preparing a New Partition

I had this problem too. And I found that it was because of gcc/config/linux.h and gcc/config/i386/linux.h and linux64.h didn't work exactly.
The LFS book says "
for file in \
$(find gcc/config -name linux64.h -o -name linux.h -o -name sysv4.h)
do
cp -uv $file{,.orig}
sed -e 's@/lib$64$\?$32$\?/ld@/tools&@g' \
-e 's@/usr@/tools@g' $file.orig > $file
echo '
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig
done
" so hard to follow.
In my opinion,I do it step by step ,
just
sed -e 's@/lib$64$\?$32$\?/ld@/tools&@g' -e 's@/usr@/tools@g' those .h and copy display to those .h
then use kwrite to add
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
at the end of those .h ,then it worked.
I hope those above could help you.

But it worked okay for me though.

Well, that's one of the great things about LFS... everybody can do whatever they want. But I recommend future readers just follow the book. The 7.2 book can be considered mature at this point. Many people have built it. The errata do not mention anything about section 5.5.
