memory exhausted error while compiling gcc.But I have 1 gb ram and 8 gb swap file. Is there any other way to work around this problem?

used a lower version of gcc. Now the error is different:

checking for MPFR... no
configure: error: libmpfr not found or uses a different ABI.
make[1]: *** [configure-mpc] Error 1
make[1]: Leaving directory `/mnt/lfs/sources/gcc-build'
make: *** [all] Error 2

Installed libmpc-dev libmpfr-dev libgmp-dev from the debian repositories in the host system.
Now the compilation of gcc is going on.

Problem with gcc refuses to be solved.


gcc: internal compiler error: Killed (program cc1)

with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions.

OK. Finally got past gcc. Had to add 1 gb ram more !!!

RAM...
It's just good stuff.
;)

now proceeding with further completion of the lfs build... No errors so far. Passed second phase, now finalising the system...

Have you checked your host system requirements to make sure that you have the correct tools to build lfs

Eddy1... Yes. I am almost finished with compilation of the basic system. All the initial errors were due to low ram (1gb) and I also had to enable swap file.

Also, I am now using debian sid instead of wheezy, to take advantage of the newer libraries (didnt get any gmp, mpc and mpfr error this time)...

Basic system took 24 hrs and xorg is expected to take 36 hrs :) And The kernel is yet to compile which will take another 5 hrs. Samsung 148N plus netbook. Intel atom processor 1GB ram

Make sure you follow the guide exactly and take it slow. It's easy to skip sections accidentally if you're rushing yourself trying to finish quickly. The first few times I had trouble building was because I ignored warnings thinking they weren't a big deal (i.e. the ones found in the version checker script at the start of the book). If you take the requirements seriously, and follow the instructions exactly you will end up with a working system, guaranteed.

basica: I tried building lfs manually. Too tedious and prone to human errors :) So I resorted to lfscript. first attempt failed due to error in my kernel config file. Now rebuilding again. So far so good !!!

There's no point in automating it, takes all the learning out of it if you're a newbie! :)

Basica: Now college has started (I am studying law). Will build a proper lfs system manually after I have gained enough experience (and have made enough mistakes :)) using this automated script. But certainly I am going to build my very own linux one day... First let me get a feel of what an lfs system works and how many new unforeseen problems I have to deal with.

A good news is that today my basic system is installed and it has been detected by the update-grub command. Now the xorg environment is being compiled. Expected to finish tomorrow.
