C compiler cannot create executables in Ubuntu 12.04
11,487
Solution 1
I had this same problem as the original poster in building xz-5.0.5.
It wasn't a problem with the CFLAGS arguments. The configure script was attempting to verify that the compiler was c99 compliant.
I needed to add CFLAGS option --std=c99 to enable it to get past this check in the configure script:
./configure CC=gcc CFLAGS="--std=c99 -O3"
Solution 2
It looks like gcc is being called with option -03
instead of -O3
, causing it to error out. Check any CFLAGS you may have specified.

I'm trying to configure cpuminer for litecoins and I get
checking whether the C compiler works... no configure: error: in `/home/username/cpuminer-2.2.3': configure: error: C compiler cannot create executables See `config.log' for more details
This is on Ubuntu 12.04 x64.
I am not sure what can be happening, but I have run updates and I have gcc installed. I read a number of articles, but they seem to be pointing to different things.
The output of the config.log is
This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
