[OMPI devel] centos-7 / rhel-7 build fail (configure fails to recognize g++)

[olivier . lahaye1]

Hi, 

On centos-7 beta, the configure script fails to recognize the g++ compiler. 
checking for the C++ compiler vendor... unknown 
checking if C and C++ are link compatible... no 
** 
* It appears that your C++ compiler is unable to link against object 
* files created by your C compiler. This generally indicates either 
* a conflict between the options specified in CFLAGS and CXXFLAGS 
* or a problem with the local compiler installation. More 
* information (including exactly what command was given to the 
* compilers and what error resulted when the commands were executed) is 
* available in the config.log file in this directory. 
** 

Solution: doing: 
yum -y install libtool-ltdl-devel 
autoreconf -if 

=> And it works. 
./configure FC=gfortran CC=gcc CXX=g++ --with-verbs=/usr --with-tm=/opt/pbs 
--with-slurm --enable-oshmem --with-libltdl 

NOTE: that during reconfigure I get a lot of: "config/opal_get_version.sh: No 
such file or directory." 
Build doesn't seem to be affected though. 

./config/ contains both opal_get_version.m4 and opal_get_version.m4sh, but no 
.sh file. 
Doing make opal_get_version.sh restarts a full reconfigure with some warnings 
about FF and other obsolete variables buf don't know how to build 
opal_get_version.sh 

Hope this helps. 

Best regards,

This is a bad idea to remove the %{?dist} IMHO.

To generate a generic src.rpm, you should use the following command:

rpmbuild -ts tarball --define 'dist %{nil}'
or
rpmbuild -bs openmpi.spec --define 'dist %{nil}'

This can be put in the main Maikefile:

srpm: tarball_bz2
rpmbuild -ts openmpi-$(VERSION).tar.bz2 --define 'dist %{nil}'


And you should keep the %{?dist} is the release tag so when built, the rpm
is clearly identified for a specific distro.

My 2 cents.

Best regards,

PS: By the way, %{?dist} is not the arch, it's the distro tag.
AFAIK, the values for main distros I know are:
rhel6 => .el6
rhel7 => .el6
centos6 => .el6
centos7 => .el7.centos
fedora-# => .fc#
Mandriva => .mdv.r when .r is the release such as 2013.1
Mageia => ?
