GCC Error in chapter 5


I am working on a project 'Pendrive Linux' i.e making a boot/root pendrive linux from scratch.I am using Ubuntu 7.10 distro as my host distribution
While installing gcc from chapter 5 of LFS book after giving the make bootstrap command i get the following error:

libgcc/./unwind-dw2_s.o libgcc/./unwind-dw2-fde-glibc_s.o libgcc/./unwind-sjlj_s.o libgcc/./gthr-gnat_s.o libgcc/./unwind-c_s.o -lc && rm -f ./libgcc_s.so && if [ -f ./libgcc_s.so.1 ]; then mv -f ./libgcc_s.so.1 ./libgcc_s.so.1.backup; else true; fi && mv ./libgcc_s.so.1.tmp ./libgcc_s.so.1 && ln -s libgcc_s.so.1 ./libgcc_s.so
exec: 2: /media/ROOT/tools/i686-pc-linux-gnu/bin/ld: Permission denied
collect2: ld returned 2 exit status
make[2]: *** [libgcc_s.so] Error 1
make[2]: Leaving directory `/home/g25/lfstrial/gcc-build/gcc'
make[1]: *** [libgcc.a] Error 2
make[1]: Leaving directory `/home/g25/lfstrial/gcc-build/gcc'
make: *** [all-gcc] Error 2

I created a directory tools in the pendrive and for all prefix paths i give the path of my pendrive tools directory.

I installed binutils which got installed successfully.
Can any body help me with this.

Just a guess, but aren't you supposed to be building the chapter 5 programs under $LFS/tools ? Looks like your at /home/g25/lfstrial.

http://www.linuxfromscratch.org/lfs/...gtoolsdir.html

Maybe that's why your getting the permission denied as the lfs user does not have permissions for your home directory?

Actually i have to build the entire system in a pendrive. So i took a different way. I thought i would make the entire system in a directory and give prefix directory as my pendrive partition and install only the required packages.So i issued the commands as superuser (root). I dont think being the root it should give any error of premission denied.Or am i thinking the wrong way....!!!!

If you've never built a LFS system, to me it would make better sense to build the system per the instructions before deviating from them.

Question As you say

i Tried following the exact instructions in LFS by using a bigger size pendrive.
Still i got stuck up at installation of glibc in chapter 5.
Error i got after issuing make command of glibc-2.5.1:

/[^

Looks like your host mawk application is giving you problems. Doing a search of mawk problems with LFS, it appears your not the only one. If your distro has mawk installed as a separate package from gawk or awk, then uninstall mawk. Then if you didn't do it already, check your host system versions against what LFS needs.

http://www.linuxfromscratch.org/lfs/.../hostreqs.html

If after you've done these steps and your still stuck, I suggest you search or post a question on the FLS mailing list.

I don't know if you have found an answer yet or not, but here is what worked for me:
I modified line 19 of the scripts/gen-sorted.awk from sub(/\/[^/]+$/, "", subdir); to sub(/\/[^\/]+$/, "", subdir); it seems that the forward-slash within the square brackets needs to be escaped. This issue will crop up 2 more times in the script, around lines 60 and 64. After those modifications, the make command worked fine.

I'm building LFS 6.3 on an eMac (PPC) running Ubuntu 7.04 kernel 2.6.20-16-powerpc
