we try to compile EPICS for a ETRAX multichipmodule

What kind of CPU is the "32 bit RISC CPU core" on this device? Is it an
ARM, and x86 derivative, or something more exotic? I can't find
anything on that website that hints the answer to this question.
Porting EPICS to a new OS and/or CPU family will probably require you to
do some work.
In order to get an base-3.14.7/src/libCom/osi/os/cris-AXIS directory we
copied the stuff from base-3.14.7/src/libCom/osi/os/Linux
We created the necessary configfile: CONFIG.Common.cris-AXIS at
base-3.14.7/configure/os/.

If you're building this for Linux, your target architecture should be
named something like linux-XXXX where the XXXX part is as generic a CPU
name as is possible. The OS_CLASS for this target architecture as named
in configure/os/CONFIG.Common.linux-XXXX would be "Linux" and there
should be no need for you to have copied the osi/os/Linux directory
contents since this code should work on all Linux systems. If you do
copy the osi/os/Linux directory then if we need to make any changes to
the Linux code in the future, your copy is likely to stop working.
On the other hand if you're really building for a new OS called 'cris'
then you may have some porting work to do - the src/libCom/osi/os code
is OS-specific, and unless the OS is posix compliant you can expect to
have to understand the src/libCom/osi directory and to write your own
implementations of some of these routines.
Compilation stops due to the following error:
make[3]: Entering directory
`/share/home/marc/hades_ETRAX/devboard-R2_01/apps/base-3.14.7/src/libCom/O.cris-AXIS'

/usr/local/cris/bin/g++-cris -c            -DUNIX               -DUNIX

What version of GCC is this?
../../../src/libCom/cxxTemplates/epicsOnce.cpp
In file included from ../../../src/libCom/osi/epicsThread.h:200,
                 from ../../../src/libCom/cxxTemplates/epicsSingleton.h:26,

../../../include/os/cris-AXIS/osdThread.h:19: parse error before `)' token
make[3]: *** [epicsOnce.o] Error 1
It looks like a "real" error in the osdThread.h file.

It works fine on all the Linux boxes we've tried it on. You're going to
have to chase this a bit more by yourself since we have no way or
replicating your results. I wish I could help, but so far I have
nothing much to go on.
