HI

I'm working on LFS(7.2), I got struck up while compiling GCC. Let me brief you this. I started with the basic of creating partitions, users and other things. I successfully configured binutilities and It got compile without error. In the case of GCC I untared all the three files (mpfr,gmp,mpc) and I configured as specified in the book, without any error. While compiling GCC it got compiled for 30 mins and then it throw me an error as.

I need to resolve this please guide me.

I can only give you a general answer when it comes to this error (configure: error: cannot compute suffix of object files: cannot compile): Remove all you've done in chapter 5 and start again.

I've seen this error a few times in other threads and none of those have a specific solution. Those people that did start again reported success afterwards, which would point to a typo or misunderstanding of the commands in the first run.

Drunna Thank you for your valuable comment.
Drunna it was resolved after examining the conflog file the actual issue is the absents of some packages in primary OS, the packages like g++,CC++,lex and some other's too. I came to know these package's are "not found" state in the conflog file, I just installed all those packages in my primary OS after that I did "make clean" and "make" It was done successively. I'm not sure this is the perfect way to resolve this or not, But this was working for me.

You shouldn't have to deviate from the book. If you do have to install extra's or edit contents to get things working then there is a fairly big chance something is wrong. You'll find out if that is true in the upcoming chapters.

BTW: The version check output looks almost correct, one entry might give problems: gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2
From the book: I haven't tried building LFS on top of the newest Ubuntu, so I do not have any personal experience yet with this.
