Hi Mark,

the executables in base and asyn are all sucessfully built.
I've used makeBaseApp.pl to create the Makefiles and other stuff for building my IOC application. This two seems to work.


The application builts for linux-x86 target. Only for linux-cris_v10
I get the error.

Florian,

Can you confirm that you successfully built some executables, like the ones in base (caput, caget) and the ones in asyn (testAsynPortDriver). Look in the bin/linux-x86 directories there. If so, then we need to figure out why it is failing to build your IOC appplication, which it built other programs OK. Is it just the size of the resulting program or something else?

What happens if you use makeBaseApp.pl to build the example IOC applicaton? Does that build OK?

Mark

PLT seens to mean "procedure linkage table". The compiler source code is
here:
https://www.calcforge.org/trac/emu-tigcc/browser/tiemu/trunk/src/core/gdb/bfd/elf32-cris.c?rev=1818

Of course, that does not mean that I have any clue what caused the error.

Well Mark,
Peter Zumbruch posted the same error some time ago on 28th of June (subject: No PLT for relocation)
At that time nobody responded ...
We also still have no solution, it seems to be a linker problem with the cris-gnu stuff.

I have never seen an error like that.

What type of system are you building for, an embedded IOC or a
workstation?

You are using asyn R4-10 which is quite old, and was tested with EPICS
3.14.8, but I don't think that is the problem.  Could you be running out
of memory on the target system?

It did build the executables in the asyn test directories OK, right?  So
the linker can build executables, just not your IOC executable?

Mark

Ok, now I was able to build synApps (Stream, Asyn, Calc, and sscan). But

still I can't build my IOC application
