I've been having the same issue using 3 different distress, my latest one being Salix 14.01 LXDE Live x86_amd64.

In a nutshell it asks for libraries that resides under /tool/lib that it can't find inside other directories. Here's an example.

make[2]: *** No rule to make target '/sources/glibc-2.23/build/rt/librt.a', needed by '/sources/glibc-2.23/build/conform/symlist-stdlibs-ISO'. Stop.
make[2]: Leaving directory '/sources/glibc-2.23/conform'
Makefile:214: recipe for target 'conform/tests' failed
make[1]: *** [conform/tests] Error 2
make[1]: Leaving directory '/sources/glibc-2.23'
Makefile:9: recipe for target 'check' failed
make: *** [check] Error 2

... libra.a does exist under /tools/lib. So I ended up doing a symlink like this to resolve it:

ln -s /tools/lib/librt.a /sources/glibc-2.23/build/rt/librt.a

Basically this happened for a total of 5 times. So I had to do those as well...

ln -s /tools/lib/librt.so /sources/glibc-2.23/build/rt/librt.so
ln -s /tools/lib/libmvec.so.1 /sources/glibc-2.23/build/mathvec/libmvec.so.1
ln -s /tools/lib/libpthread.so /sources/glibc-2.23/build/nptl/libpthread.so
ln -s /tools/lib/libdl.so.2 /sources/glibc-2.23/build/dlfcn/libdl.so.2

... And at the end it compiled successfully.

Did I do something wrong that make this not finding the right libraries at the right place?

Thx....

I would say something went wrong at ch 6.6 The 1st part, If you read the discription "The purpose of each link".

... Thx for your answer.

I checked /usr/lib and this is what i have....

/usr/lib/libmvec.so.1 doesn't exists
/usr/lib/libdl.so.2 doesn't exist...
/usr/lib/librt.so exists, but it's a symbolic link to points to ../../lib/librt.so.1 but that file doesn't exists.
/usr/lib/libpthread.so exists. (???)

If you check chapter 6.6, there is no mention to have those files copied over.

I checked more the logs, and i saw this....

/bin/ginstall -c /mnt/lfs/sources/glibc-2.23/build/nptl/libpthread.so /tools/lib/libpthread-2.23.so.new

first.... I only have in /bin those files: bash, cat, echo, pwd, sh and stty. I did a find / -name 'ginstall' and found nothing. Should i create a symlink /bin/ginstall that points to /tools/bin/install (which actually exists)?

Second, why is it /mnt/lfs/sources/.../? Isn't supposed to be straight /sources/.../?

The /tools/lib portion is right though... Weird.

Is that the problem?

Thx...

If you are seeing /mnt/lfs anything your not in the chroot enviroment

... That's the thing. I am in it.

Oh well. My symlinks did the job and the others are compiling fine so... Case closed.

Thx.
