Re: Mainframe C Link Step Error - using pthread (POSIX)
LE pthread functions are mapped to names starting with @@PT*. You can see this by browing pthread.h and checking the #pragma map(pthread, ... ) statements. I would suggest that you are calling a pthread function that is not declared. Because you're using the pre-linker you should check to pre-linker output to see what the unresolved symbol is. Binder error messages are practically useless if you use the pre-linker.

Re: Mainframe C Link Step Error - using pthread (POSIX)
The IEW2456E says module not in SYSLIB/SYSLIN. I checked the C and LE libraries and could not find PTHREAD@ (lots of refs in the COMPILER/RUN TIME LIB docs). This can most likely be fixed in one of 2 ways depending on what is desired. If you really want PTHREAD@ hard-linked in you LMOD, I would suggest using the pre-linker to see if this resolves the issue. (actually the pre-linker might be needed in either case. Not sure.) If you don't want PTHREAD hard-linked, then add NCAL to LPARM=. This will force a dynamic call to PTHREAD@. If PTHREAD still cannot be found, you will get an execution error (S0C4, S0C1) which will show up as a U4038/9 error and an LE dump. I presume you are familiar with the trade-offs between hard-linking and dynamically calling a module.

Re: Mainframe C Link Step Error - using pthread (POSIX)
We believe this module needs to be dynamically linked for the purposes of utilizing sockets. If you don't mind, could you briefly explain hard-linking (static?) versus dynamic-linked with regard to this?
