The problem is the -I with no directory after it. That causes the -MM to be ignored.  There is probably a USR_INCLUDES with an undefined macro.

Hello tech-talkers,

I am trying to install MEDM on CentOS for the first time but I get an error on the process. I have downloaded the tar file corresponding to the version 3.1.11 and unzipped it in the EPICS/extensions/src directory. Then I do make from the extensions directory and get the following error:

Am I missing any step in the installation process? I haven't find any installation manual so it is possible I am missing something obvious.

Thanks,
