Hello,
I habe a problem using a recent libvirt-Version (0.4.4) (installed from
backports.org) in my own programms.
I had used an older Version a while ago, but I think something might
have changed in the API(?), since the old code has the same problems
now.
I include the headers
#include <libvirt/libvirt.h>
#include <libvirt/virterror.h>
but when linking, I'll get errors like
XSSserver.o: In function `XSSserver::XSSserverinitializeService(void*)':
/root/rsplib-2.5.0/rsplib/XSSserver.cc:68: undefined reference to
`virInitialize'
/root/rsplib-2.5.0/rsplib/XSSserver.cc:72: undefined reference to
`virConnectOpen'
here is the function:
bool XSSserver::XSSserverinitializeService(void* userData)
{
if ( virInitialize() != 0) {
puts("WARNING: vir Initializew failed\n") ;
return false;
}
virCon=virConnectOpen(NULL);
if (virCon != NULL ) {
return true;
}
puts("WARNING: Initialisierung misslungen") ;
return false;
}
Any hints what I've done wrong/how to debug that problem?
regards Johannes

Hi,
I guess You are missing linking libvirt.
If not, Please check libvirt library by using nm command.
Thanks

What do you mean, would it be autmoticaly linked like other librarys in
/usr/lib? (sorry, I'm not a c/c++ expert)
If not, Please check libvirt library by using nm command.
# nm /usr/lib/libvirt.so.0.4.4
nm: /usr/lib/libvirt.so.0.4.4: no symbols

including

So the libary itself should be ok, and I have only some stupid errors in
the makefile?

Thanks for the hint, after a bit "googeling" setting LDFLAGS and runnig
the ./configure script solved the problem.
