Hello,

May I ask what kind of Linux that has support for VME devLib? Can I install some software to make a normal Linux support VME devLib?

Unfortunately, I am not aware of anything I would describe as "normal"
about VME support in Linux.  You may have a lot more work than you
expect here.  :(

To start with, can you describe your hardware?  What sort of VME cards
are present in your crate(s) ?

I would like to build mca/lib/liunx-x86_64/libSIS38XX.a. According to the notes in mca/mcaApp/SISSrc/Makefile:

# If your version of Linux has support for VME devLib uncomment following line
#LIBRARY_IOC_Linux += SIS38XX

In my $EPICS_BASE/include directory, and I find files of:
devLib.h
devLibVME.h
devLibVMEImpl.h
But that seems not enough, and the make of mca with option of "LIBRARY_IOC_Linux += SIS38XX" has errors of:
../drvSIS3820.h:208:3: error: ‘DMA_ID’ does not name a type

My system:
EPICS_base-7.0.7
mca-R7-9
linux_x86_64: Ubuntu 22.04.2 LTS
devLib2-2.12

Also tried:
EPICS_base_3.14.12.8
mca-7-8
linux-arm; RHEL
(no devLib2)

Thanks a lot,
Rong
