I'am trying to use cppunit 1.8.0 with SunOS 5.8 and gcc 2.95.2.
I've already spent few hours to get it working - unfortunatelly with static linkage only. Now I stuck in bigger problem. Static linkage disqualifies using pthreads because it has only dynamic library. But even when I do not use pthread library explicit when linking, but only declaring -D_PTHREADS, linker has problems with cppunit. What's going on? On linux it works, on Solaris not. Using followind main.cpp file defined as:

#include <cppunit/ui/text/TestRunner.h>
int main( int argc, char **argv)
{
  CppUnit::TextUi::TestRunner runner;
  runner.run();
  return 0;
}

when compiled this way, everything is ok:
$ g++ -c -o main.o main.cpp
$ g++ -o test main.o -lcppunit

but doing such thing, is not:
$ g++ -D_PTHREADS -c -o main.o main.cpp
$ g++ -o test main.o -lcppunit
Undefined                       first referenced
symbol                             in file
CppUnit::TextUi::TestRunner::run(basic_string<char, string_char_traits<char>, __default_alloc_template<true, 0> >, bool, bool, bool)main.o
ld: fatal: Symbol referencing errors. No output written to test
collect2: ld returned 1 exit status

Any ideas? It seems that Java is better solution, especially in such problems like this :/

Second problem is that I'am not fluent in low-level updates. I have read about problems with exception handling (ld does not support building shared libraries with exception suport because it is designed for C not C++) which causes abort (and core dump) on assert which raises exception. What should I do? Do I need replace ld linker to allow dynamic binding C++ libraries at runtime? Keeping in mind I need pthreads it looks like only way. What is minimal change on development server? I do not want begin revolution on this SunOS host.
Thanx for any advice.
