(6.17. GCC-4.6.2) Is it safe to continue after these libmudflap errors?

neohexane · 06-30-2012, 04:46 AM

The LFS 7.1 book says that it's not safe to move on if you have had errors that differ vastly to this after doing "make -k check" for GCC. Would you say that my errors differ a lot from the errors in the link, and is it safe for me to move on? I'm building on openSUSE latest version 32-bit KDE.

Hi

I have googled and havn't found alot to help out, I know this dosn't help
Did you use the part

Code:

ulimit -s 16384

I did find alot of reports about libmudflap failiure acceptable but to what extent no one sayes.
Maybe rebuild gcc again, remove the gcc-4.6.2 dir and gcc-build dir and start again see if the same failures appear.
Did you copy and paste the commands to build gcc?
I hope someone can come along and give a positive ans If not I might be inclined to carry on.

I'm working the book right now, and that list looks very much like what I got on the gcc tests, and also very much like the list the online book says to check against:

Results can be compared with those located at http://www.linuxfromscratch.org/lfs/build-logs/7.1/ and http://gcc.gnu.org/ml/gcc-testresults/.

This list is from the first link:

I am proceeding with my build.

Ah, it's okay. I went through the rest of the book as normal, and I successfully booted the system with no errors. I just thought that there were too many of those libmudflap errors, even though they looked similar.

Hi

Glad it all worked out ok
