linker problems

[Joerg Schaber]

Hi,

I'm trying to compile and link a cpp-file with  the following 
commandline  options:

g++ -I/libpath/ -lmylib  p.cpp

the compiling step succeded, but the linking step fails with  this error 
message:

/tmp/ccqLyDUW.o(.text+0x124): In function `main':
: undefined reference to `CVersion::CVersion()'
/tmp/ccqLyDUW.o(.text+0x147): In function `main':
: undefined reference to `CVersion::setVersion(long, long, long)'
/tmp/ccqLyDUW.o(.text+0x18e): In function `main':
: undefined reference to `CVersion::~CVersion()'
/tmp/ccqLyDUW.o(.text+0x1a7): In function `main':
: undefined reference to `CVersion::~CVersion()'
collect2: ld returned 1 exit status


I checked with this line "nm -C libmylib.a | grep CVersion",  whether 
the function "CVersion" is contained in the ibmylib.a.
Is it, but the linker won't find it anyway ...

I got a hint, that there's a command line option which forces the linker 
to search multiple times through the libraries instead of one time, but 
I can't find it.
Has somebody a idea which is the command line option I need? Or maybe 
another  solution?

Thanks a lot
