[SOLVED] where are crt1.o, crti.o, ........

michanux · 03-15-2015, 08:06 AM

Hello

on page
http://www.linuxfromscratch.org/lfs/...r05/glibc.html

I did the glibc test. "$LFS_TGT-gcc dummy.c" breaks with the issue:

Code:

/mnt/lfs/tools/bin/../lib/gcc/i686-lfs-linux-gnu/4.9.1/../../../../i686-lfs-linux-gnu/bin/ld: cannot find crt1.o: No such file or directory
/mnt/lfs/tools/bin/../lib/gcc/i686-lfs-linux-gnu/4.9.1/../../../../i686-lfs-linux-gnu/bin/ld: cannot find crti.o: No such file or directory
/mnt/lfs/tools/bin/../lib/gcc/i686-lfs-linux-gnu/4.9.1/../../../../i686-lfs-linux-gnu/bin/ld: cannot find -lc
/mnt/lfs/tools/bin/../lib/gcc/i686-lfs-linux-gnu/4.9.1/../../../../i686-lfs-linux-gnu/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status

My LFS installed these missing files in
"/mnt/tools/lib/"

It should have been installed in /tools/lib and because of symlink in /mnt/lfs/tools/lib.

Hello
Sorry I told the wrong path to you.

This is my path too. But the problem does not disappear. I catched the issues of "$LFS_TGT-gcc dummy.c" by "strace"

It does not look to "/mnt/lfs/tools/lib/..". So I linked "/mnt/lfs/usr/lib" to "/mnt/lfs/tools/lib". Now all things works fine and I receive the message "[Requesting program interpreter: /tools/lib/ld-linux.so.2]"
This is not the way the LFS book describes it. Have you a hint to get out of this troubles?

Try finding the file in fs tree by:

Code:

find /tools -name "crt1.o"

Report where it is present. Have you setup your environment variables correct?

The answer of:

Code:

find -L /tools -name "crt1.o"

is
"/tools/lib/crtl.o"

"/home/lfs/.bashrc"

Code:

set +h
umask 022
LC_ALL=POSIX
LFS=/mnt/lfs
LFS_TGT=$(uname -m)-lfs-linux-gnu
PATH=/tools/bin:/bin:/usr/bin
export LFS LC_ALL LSF_TGT PATH

What build commands have you used for building binutils and gcc pass1.

I cut this from "/home/lfs/.bash_history"

Code:

../binutils-2.24/configure --prefix=/tools  --with-sysroot=$LFS --with-lib-path=/lfs/tools/lib --target=$LFS_TGT --disable-nls --disable-werror

Code:

../gcc-4.9.1/configure --target=$LFS_TGT --prefix=/tools --with-sysroot=$LFS --with-newlib --without-headers --with-local-prefix=/tools --with-native-system-header-dir=/tools/include --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libatomic --disable-libgomp --disable-libitm --disable-libquadmath --disable-libsanitizer --disable-libssp --disable-libvtv --disable-libcilkrts --disable-libstdc++-v3 --enable-languages=c,c++

You have given a wrong path. This might be the cause of problem.

Sorry, this is not the solution.

I am look for another trace. This Issue from above indicates this line:

Code:

access("/mnt/lfs/usr/lib/crtn.o", R_OK) = -1 ENOENT (No such file or directory)

ch_ld-gcc
The "usr" should be a "tools".

This is the page on LFS book
http://www.linuxfromscratch.org/lfs/...gcc-pass1.html
In this page there are words like this: "...while the second one replaces hard-coded instances of “/usr”." It deals of the sixth line in the following
file "ch_ld-gcc". Replacing "usr" by "tools".

Code:

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 STANDART_STARTFILE_PREFIX_1
#undef STANDART_STARTFILE_PREFIX_2
#define STANDART_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDART_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig

Maybe there is a mistake in this or the "sed" function does not work. Path is "/bin/ch_ld-gcc" in Debian. Activating this file it only shows the copies of the first, second and third line.
How can I check the performance of the last lines?

How you know unless you test it.

The problems arises with use of 'ld' command; part of binutils. And you given wrong arguments while building it. Particulary the default library path it looks for.

michanux · 03-26-2015, 04:01 PM

Code:

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 STANDART_STARTFILE_PREFIX_1
#undef STANDART_STARTFILE_PREFIX_2
#define STANDART_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDART_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig

After the last line I add the command "done". So this troubles disappear!
