[Q]rfc c library compile error

Question

Hello!
I am establishing the IVR call to the SAP.
The IVR machine is SUNOS 5.6.
IVR should use the library, librfc.a,
but when I compile with this library,
I got the compile error like below.
The error message is
undefined first reference
symbol in file
select_large_fdset ./lib/librfc.a(cpictlib.o)
ld: fatal: Symbol referencing errors. No output written to saprfccl
I compiled with the below option,
/opt/SUNWspro/bin/cc -Xc -xcg92 -I ./include -L ./lib
saprfccl.c -o saprfccl -lrfc -lsocket -lnsl -ldl -lm -lw.
librfc.a is the library referencing the function, select_large_fdset.
but I don't have the program source because it is only provided as .a by the SAP.
It looks that the standard library in this OS version does not have this function, select_large_fdset,
according to my company technical support investigation.
Are there any ways to get the library with this function without server upgrades?
Thanks

Answer 1

Thanks for your help.
librfc.a is provided by SAP.
I put this library in ./lib directory.
and used the -L option to link with it.
Anyway I put this path to LD_LIBRARY_PATH,
but it is same.
The problem is
that librfc.a is referencing the function, select_large_fdset.
This function is normally in the standard c library, libc.so.
But because the SUNOS that I am using is so low, ver.5.6,
libc.so in the standard c library does not have this function, select_large_fdset.
So my question is how can I use this library, librfc.a without the server upgrade to the upper version
that has the standard library that has function,select_large_fdset.
Is it not possible?
Please tell me yes.
