won't compile gcc

ph0t0n1st · 04-10-2014, 12:14 PM

Hi i am building CLFS on Fedora 20 x64. It went smooth so far however it fails when i make gcc

Code:

checking for x86_64-unknown-linux-gnu-gcc...  /clfs/gcc-build/./gcc/xgcc -B/clfs/gcc-build/./gcc/ -B/cross-tools/x86_64-unknown-linux-gnu/bin/ -B/cross-tools/x86_64-unknown-linux-gnu/lib/ -isystem /cross-tools/x86_64-unknown-linux-gnu/include -isystem /cross-tools/x86_64-unknown-linux-gnu/sys-include   
checking for suffix of object files... configure: error: in `/clfs/gcc-build/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make: *** [configure-target-libgcc] Error 1

and the config.log is here

I can't figure out. Please help me out

As i recall fedora is on the list of OS's NOT TO USE !

install Debian stable
Then build LFS on that platform

I see, as a novice to LFS i didn't expect or know that. The reason i get into LFS/CLFS(since i have x64 machine) is i want to learn linux without struggling on bash,error reports and google,or LQ on most errors i get. But i guess on fedora and Which distro can i use for LFS?

I am on x64 host. I removed fedora and installed mint since its debian based and debian is suitable for LFS/CLFS as i heard. But however i am on 64 bit system. Is that a problem? What distro(even live distro) you would recommend for latest LFS(7.5) and CLFS (2.1.0) I really want to learn to build linux to learn linux but that distro problems cause lots of problems for 3 days and nights for me. So much googling,mail list reading etc. It really would be nice if you could guide me for it.

Thank you

then LFS is the wrong os to try to LEARN on
it is 100% all about using the terminal
and SOLVING errors

it sounds like what you want is a windows XP or 7 "point and click" replacement

that is NOT LFS

it sounds more like you want Linux Mint 16 ( or 13 LTS)
or
Ubuntu 13

you might want to Download or buy the current LFS BOOK
http://www.linuxfromscratch.org/lfs/download.html
--- a bit OLD -- 7.5 is the current version
http://www.amazon.com/Linux-From-Scr.../dp/1300019832

and study it, like you would for a 400 level collage class
and i do mean take a full semester to STUDY the LFS text book

Isn't that the fun of using LFS?

LFS, Gentoo, Slackware, and CRUX are all about back-to-basics GNU/Linux which uses a lot of command-line stuff.

If you want to build LFS, we've recommended one distribution only for this. I suggest you backtrack through posts here, and then go learn that distribution before you continue onward with LFS. You have to actually know how to use GNU/Linux core functions in order to really utilize LFS.

I'm not real familiar with cross-lfs, but it looks like you've either got a dangling connection to the previous toolchain or a needed static library wasn't built. From what I saw in searching, at least 1 page in the CLFS book explains that libstdc++ must test okay or you could end up with character/language issues.

Did you miss a sed somewhere that was supposed to force g++ to compile without dynamic links? I say this cause there is a call to /bin/ld and it can't find it. Check your tools directory for .a files.
