Hi Brian,
thanks for your reply.
I didn't change PFNFYLEVEL. May be it's a chance.
What I did was the following.
I tracked down the calls until request of DSOs. All seems to work
correctly. But if the _pfdFindConverterDSO trys to get the addresses of
the loader functions it gets only NULL-pointers.
My extension to libpfdu doesn't change any original code. There's only a
function added which returns the ability of a certain converter to
load/store files.
For all that I believe that there must be a difference between my compiled
libpfdu and the original delivired.
I have verified my guess with simple test code:
#include <Performer/pfdu.h>
#include <Performer/pfdb/pfflt.h>
// ***** main *****
// main function
int main(
int argc,
char **argv)
{
if (argc < 2) {
cerr << endl << argv[0] << ": Missing argument." << endl
<< "Usage: > " << argv[0] << " <model_file>" << endl;
return 1;
}
pfInit();
pfdInitConverter("flt");
pfdConverterMode("flt", PFFLT_FLATTEN, FALSE);
pfConfig();
pfNode *pPfNode = pfdLoadFile(argv[1]);
}
This application works fine when linked against default libraries but
fails when linked (statically) against my extended libpfdu.
All sounds very weird, doesn't it?
Version mismatch? Wrong compiler version?
BTW, I use this code on IRIX/Pf2.2.7 since beginning of this year without
any problem.
Best regards,
Dirk.
P.S.: "Couldn't initialize model loader..." is thrown by my own
code.
But before "PF Warning" appears, also.
