[elrepo] nvidia-x11-drv-340xx-340.107-2.el7_6.elrepo.x86_64 conflicts ocl-icd

[Oscar Conchillo-Solé]

Hi all

I'm having a strange problem that probably you know the solution

I had gromacs and nvidia-x11-drv-340xx (nvidia from el repo) packages 
installed up until now without a problem, but now in one computer, when 
I update the nvidia drivers it says it conflics with ocl-icd.

ocl-icd was installed as a requirement for gromacs. I guess the conflict 
is that both provide "/usr/lib64/libOpenCL.so.1"

However, in another computer which has almost identical installation 
(almost the same packages) but different nvidia graphics card (uses 
nvidia-x11-drv-390xx instead of the previously mentioned) when I install 
gromacs I have no clonflict problem and ocl-icd does not appear as a 
requirement.

Another thing that I'm not sure I understand is that the package that 
provides "/usr/lib64/libOpenCL.so.1" is not nvidia-x11-drv-390xx or 
nvidia-x11-drv-340xx but nvidia-x11-drv-390xx-libs or 
nvidia-x11-drv-340xx-libs which are not the ones reported to conflic.

I find it strange that having both cases the library 
"/usr/lib64/libOpenCL.so.1" installed by a elrepo nvidia package in one 
case it requires another package to provide it (ocl-icd) and in another 
don't.

here is my output of "yum install gromacs" in the computer with the 340 
driver installed and updated:

  You could try using --skip-broken to work around the problem

PS: I have other computers with require also the nvidia 340 driver, I 
have it installed from "elrepo" and no probmels until today, however now 
when I try to update it it reports a conflict with ocl-icd and does not 
allow the update:

Could you please help me to keep installed and updated version of 
nvidia-x11-drv-340xx and gromacs at the same time as I have always have 
it without problems or as I still have in the computer that I can use 
nvidia-x11-drv-390xx?

thank you very much
