[SOLVED] Building Mesa 17.3.4 on Blfs 8.2 systemd failed

rabidlinux · 03-19-2018, 07:12 AM

Hi to all,

After being sucessful building 8.1 Systemd thought I would dig into 8.2.
Things went well to I got to X and Mesa.

Here is a copy of configure fail.
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/sources/mesa-17.3.4':
configure: error: C compiler cannot create executables
See `config.log' for more details
I looked at the configure.log and have no idea what I'm looking at.
Thankful for any help.
Have a good Day

You have mistyped something, most likely in the first line of the configuration:

Code:

./configure CFLAGS='-O2' CXXFLAGS='-O2' LDFLAGS=-lLLVM

I bet you put -0(zero)2 instead of -O(Oscar)2. It's an easy mistake to make. "O" represents the level of optimisation in the resultant code.

Thanks Hazel,
I will give it a shot when I return

Hey Hazel,

I tried what you suggested but didn't work.
Thanks anyway.

How are you entering your instructions? For anything really complicated like this mesa build, you should copy and paste, not type by hand. That particular error after a string of successful builds always indicates that you have told gcc to do something silly or illegal.

The best part of config.log to look at is the last part. Post the last 20 lines if necessary, between code tags.

Hello Hazel,
I cut and paste all instructions. Will look at config.log to see if something looks weird.
Thanks

Decided to start with x and see if it was there
