Cannot find gcc-debuginfo.x86_64 package

[fdumoulin]

Hi,

Trying to analyse OpenMP regions using Intel VTune Amplifier, I follow the prerequisites on this page https://software.intel.com/en-us/node/712270.

libgomp.so.1.0.0 doesn't contains any symbol so I tried to install gcc-debuginfo.x86_64, but I got the following message :

Code: Select all

$ yum install gcc-debuginfo.x86_64
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: centos.mirror.fr.planethoster.net
 * epel: ftp.heanet.ie
 * extras: centos.mirror.fr.planethoster.net
 * updates: centos.mirror.fr.planethoster.net
No package gcc-debuginfo.x86_64 available.
Error: Nothing to do

How can I get debug information on my Centos 7.3 ?

Thanks,
Fred

Is there anything else to do ?

Thanks,

Debuginfo packages give you separate files like /usr/lib/debug/usr/lib/gcc/x86_64-redhat-linux/4.8.2/libgomp.so.debug
