Re: [Discuss-gnuradio] error

[Martin Dvh]

Problem seems to be in the use of cppunit.
All the failures with gcc-3.4 are one the first invocation of
TextTestRunner.addTest()

my cppunit version is:
cppunit 1.10.0-5

But I suspect this is the one which needs to be compiled with gcc-3.4 in stead 
of gcc-3.3.
Does anybody know if it is possible to have multiple gccunit versions installed 
(and how do I use them this way)?

I runned all tests under gdb.
they all fail on a line containing someTextTestRunner.addTest(sometest)

The problem for gcc-3.4 seems not to be in test_vmcircbuf.
This one gets a SIGBUS but this is caught. This is the only test that runs to 
completion.
All other tests fail on the first .addTest(...)
