Experimental Physics and Industrial Control System
I'm trying to build the EPICS 3.12.2 Channel Access Client on Sun4, and I'm
having a problem I hope someone can help me with.
When I compile access.c, I get the following error message on line 3474:
'vprintf' undeclared (first use in this function)
Line 3474 actually accesses epicsVprintf, which is #define'd to vprintf in
epicsPrint.h. The problem appears to be the assignment statement that
treats vprintf (a Unix function) as a function pointer. When I rewrote the
code to do the same thing without the assignment statement, it compiled
fine; but that allowed several similar (vprintf) problems to be found, and
they couldn't all be fixed so easily.
The thing is, the same code compiles fine on the HP700 machine, leading me
to think it's a difference in the gcc platforms (both compilers are gcc
2.7.2). I'm assuming that many people compile the CA client on Sun4, so I'd
appreciate any insight that can be shared.
Thanks for any help.
