Hi, I hope you can help me with this issue:

I am running 4.7.2-1-ARCH 64bits and all the host requirements are met, except the three libraries .la (although I don't think this should be an issue, as these libraries are included and built with GCC when following the book's instructions). I get the following error when running the make command in pass 1 of GCC:

Thanks in advance!

ok arch is to new to build lfs-7.9, try building lfs-7.10
http://www.linuxfromscratch.org/lfs/view/7.10-rc1/

"GCC-4.7 including the C++ compiler, g++ (Versions greater than 5.3.0 are not recommended as they have not been tested) " from host system requirments

hi

i run arch as primary os, and first time i got similar issue in gcc, searching i found a lot dep missing you need install headers for arch.equivalent for 'build essential' in debian. i didnt want bother whit this in arch, beacouse you need to install bunch of staff to have all deps sadisficte. i installed debian in qemu, after install only install build-essential and it will work.

Okay, I will give 7.10 a shot then. Thanks!
