Hi,

My system is RHEL 6.8. In building MED 3.2.1 for Code_Saturne 5.0.4, it encountered the following problem. Why does it happen and how to get around it? Thanks.

Hello,

Which directory are you installing from ? Did you create a directory as root, or using sudo, or did you only use you standard account (which is the recommended option) ?

Hi Yvan,

Thank you for reply. I installed it from my Downloads directory with my standard account (without using sudo or su). It is a cluster machine, and I don't have the super user right anyway. Now, I checked the permissions of the reported file and the directories "./med-3.2.1_SRC/doc/jpg/xmdump4.jpg". They are as the following:
drwx------ 9 fanf4 leads 600 Nov 7 2016 med-3.2.1_SRC
drwx------ 8 fanf4 leads 190 Nov 7 2016 doc
drwx------ 2 fanf4 leads 266 Nov 7 2016 jpg
-r--r--r-- 1 fanf4 leads 121849 Apr 14 2016 xmdump4.jpg

I also installed the same downloaded Code_Saturne-5.0.4 package on a Ubuntu workstation. Again, from my Downloads directory and using only standard account right. This time, the med-3.2.1 package was successfully installed. Checked permissions of the file and the directories:
drwxrwxr-x 9 ffan ffan 4096 Oct 13 09:50 med-3.2.1_SRC
drwxr-xr-x 8 ffan ffan 4096 Nov 7 2016 doc
drwxr-xr-x 2 ffan ffan 4096 Nov 7 2016 jpg
-r--r--r-- 1 ffan ffan 121849 Apr 14 2016 xmdump4.jpg

Apparently, the Ubuntu installation gave more permissions to group and other, but they both were installed with user account and to user directory.
