LFS Chapter 5.10: GCC 7.2.0 PASS 2 ERROR CANNOT COMPUTE SIZEOF(long long) PLEASE HELP!!
 

Hi I'm really new to linux, I was thinking of posting this at the newb section, anyways I have been following the book and everything was going smooth until I get to chapter 5.10, wherein the error happens when I make/compile the gcc 7.2. It says:
checking size of long long... configure: error: in `/mnt/lfs/sources/gcc-7.2.0/build/gcc':
configure: error: cannot compute sizeof (long long)
See `config.log' for more details.
Makefile:4186: recipe for target 'configure-gcc' failed
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory '/mnt/lfs/sources/gcc-7.2.0/build'
Makefile:902: recipe for target 'all' failed
make: *** [all] Error 2

I really need help right now, the deadline for our project submission is on friday. Your help will be greatly appreciated.

This is the config.log file. hope this helps:

sizeof (long long) ? on a 32-bit host?

Try a 64-bit live cd.

There will be problems when trying to cross compile for a
different ABI. If you are running on a 32-bit host with a
64-bit cpu some configure scripts will fail.

The CLFS book will show you how to build a proper 32-bit
target.

you need to tell us what you are using as a host, the results of the version check script and please dont use so many capitals its the forum equivelent of shouting, and wont get an answer any quicker.
also what version of the book you are using.

A newbie shouldn't even be using LFS. I suggest that you read the prerequisites page of the LFS manual, especially the first paragraph.

I am using 32bit Ubuntu on a virtual machine.
2gb ram
4cores single cpu
1gb VRAM
25gb hdd
