[Log4cplus-devel] log4cplus and undefined symbol with Sunstudio

[Jeremy C. R. <re...@re...>]

Using Sunstudio CC: Sun C++ 5.10 SunOS_sparc 2009/06/03

$ /usr/bin/CC  -I/udir/jreed/opt/log4cplus/include -L/udir/jreed/opt/log4cplus/lib -llog4cplus ~/l1.cc 
Undefined                       first referenced
 symbol                             in file
log4cplus::Logger::~Logger()        l1.o
log4cplus::Logger log4cplus::Logger::getInstance(const std::string &) 
l1.o
ld: fatal: Symbol referencing errors. No output written to a.out


Here is example code:

$ cat ~/l1.cc 
#include <log4cplus/logger.h>

int main ()
{
 using namespace log4cplus;
 Logger logger = Logger::getInstance("main");
 return 0;
}

Using g++ for this compiles/links fine. I think Sunstudio is more 
strict by default.

Note that the installed log4cplus was builting using g++ (GCC) 3.4.3 
(csl-sol210-3_4-branch+sol_rpath).

So the installed header and the logger.cxx code has:

  static Logger getInstance(const log4cplus::tstring& name);

  getInstance (const log4cplus::tstring& name)

But nm shows:

[2134]  |    251340|      48|FUNC |GLOB |0    |227    |log4cplus::Logger::getInstance(std::string )

Notice that the "const" and the "&" (ampersand) is gone.

As for the other undefined symbol, I don't know.

$ nm ~/opt/log4cplus/lib/liblog4cplus.so | c++filt | grep log4cplus::Logger::~Logger
[1852]  |    251568|     104|FUNC |GLOB |0    |227    |log4cplus::Logger::~Logger()
[2116]  |    251136|     108|FUNC |GLOB |0    |227    |log4cplus::Logger::~Logger()
[1369]  |    251460|     108|FUNC |GLOB |0    |227    |log4cplus::Logger::~Logger()


I had this problem with 1.0.4 and with code from subversion (I am at 
revision 1535).

This may not be a log4cplus problem, but maybe someone here recognizes 
this or has some ideas?

Thanks,
