I'm compiling InterViews 2.6 with gcc2.2.2 using sun's
assembler on a Sun4/110 with SunOS4.1.1.
I have no problems with the compiliation until the link stage. The
InterViews libraries compile and archive successfully, but when I
compile application code and try to link with these libraries I get
undefined symbols. After looking around at the object files and the
source, I found that the symbols that are reported as undefined are
each delcared as private or protected static variables of classes in
the libraries.
The output from the link looks like:
ld: Undefined symbol
__8WorldRep$_host
__6Sensor$maxchannel
__6Sensor$channels
The delcarations in the source look like:
class Sensor : public Resource {
public:
//...
protected:
static unsigned channels;
static int maxchannel;
//...
};
and...
class WorldRep {
public:
//...
private:
static char _host[100];
//...
};
Are there options that I should be specifying to gcc to
correct this?
Thanks,
Rick Jesse
