Ralf,

I think the problem is that TestFunc.o remains after you make C version
DLL. When you try to build C++ version, it confuses that TestFunc.o is
already built. Do 'make -f Makefile clean' before you make C++ version.
It should work fine.

$ makecint -p -mk Makefile -dl testfunc.dl -h TestFunc.h -C TestFunc.c
$ make -f Makefile clean
$ make -f Makefile

$ makecint -p -mk Makefile -dl TestFunc.dl -H TestFunc.h -C++ TestFunc.C
$ make -f Makefile clean
$ make -f Makefile

About garbage in /tmp directory,
Cint is supposed to delete them when program termination. It is done in source
file src/end.c line 591. Temp files are left only when cint is terminated
abnormally. I could not find any clean solution to this. If temp files always
remain, there must be some problem.
