I am trying to install Open MPI 2.1.0 version on our CentOS machine. I followed these steps:

tar -xvf openmpi-*
cd openmpi-*
./configure --prefix="/home/$USER/.openmpi"

*** C compiler and preprocessor
checking for gcc... (cached) gcc
checking whether we are using the GNU C compiler... (cached) yes
checking whether gcc accepts -g... (cached) yes
checking for gcc option to accept ISO C89... (cached) unsupported
checking whether gcc understands -c and -o together... (cached) yes
checking for gcc option to accept ISO C99... unsupported
configure: WARNING: Open MPI requires a C99 compiler
configure: error: Aborting.

I searched for same problems like this and tried to install C99 and whatever missing. and no progress. Do you have comment or solution?

What version of `gcc` is installed? – Kusalananda Mar 22 '17 at 08:31
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-15) – Abolfazl Mar 22 '17 at 08:33
Well, that's definitely a C99 compiler (and C89). Could you add the part from `config.log` where it fails to compile the last test? (or put the whole `config.log` on http://pastebin.com or somesuch place and link to it?) – Kusalananda Mar 22 '17 at 08:47
I provided it in my [dropbox](https://www.dropbox.com/s/6whn7bn9pv6s0o7/config.log?dl=0) – Abolfazl Mar 22 '17 at 08:55
It looks like `gcc` is acting like a C++ compiler... I don't know why. You didn't link `gcc` to `g++` or something similar? – Kusalananda Mar 22 '17 at 09:03
As far I know and checked the `bashrc` I did not. – Abolfazl Mar 22 '17 at 09:07
CentOS 6.8 comes with gcc 4.4.7. Does your gcc come from a special repository, such as one of the Software Collections? – Mark Plotnick Mar 22 '17 at 16:18
I don't know. It's a shared machine. But I have root access. do you suggest to update or replace the gcc compiler? – Abolfazl Mar 22 '17 at 16:32
No, don't change the installed compiler; that can break other things. I see from your logs that it's from devtoolset-2; I'll see if I can reproduce your compilation errors with that. – Mark Plotnick Mar 23 '17 at 14:09
