esqlc or cc compilation error : _abi_...grent Undefined in /usr/lib/libnsl.so
Hi, I have installed SQL 7.20.UD7 IDS 7.30.UC8-1 CLIENT SDK 2.20 ESQLC 9.2 on NCR os MPRAS 3.02 ( or may be 3.20) The client has some C and Esql/c programs that I am not aware of. The only thing that I know is executing make should take the Makefile and give me the new executable. While executing the make file I get the following Fatel error and I don't know what to do further. Undefined Symbols first referenced in file _abi_getgrent /usr/lib/libnsl.so _abi_endgrent /usr/lib/libnsl.so _abi_setgrent /usr/lib/libnsl.so I have been working with the Makefile for one full day and now I have some idea as to what it contains. At first I had a lot of undefined symbols but after changing the Makefile and including many other libraries I have come to 3 errors. I am not sure which file has this objects defined. If anybody else has any idea then email it to me. Thanks, Sunil Thakkar. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
If this is a recent upgrade you may have older objects in libraries that were compiled with earlier ESQL/C which had a different library layout and so will not link with the new code. Recompile all library code when upgrading ESQL versions. Art S.

If it does not -- if it uses either the C compiler or the loader directly -- then the odds are that the library list has changed and the makefile hasn't. Moral: always, but always, use the esql script to link programs. Otherwise, go poking through all the libraries in /usr/lib and /lib and find out which, if any, defines the _abi_* functions; not just the group entry ones which you're missing, but any such functions. This will probably give you the necessary info. If no library defines any of the _abi_* functions, then you've somehow got the wrong version of libnsl.so on your machine. If some library defines a bunch of _abi_* functions but not the ones you are missing, then there is still, probably, an o/s installation problem. And if you find a library which defines the three missing functions, you know you need to add that to the list of libraries (probably in the esql script, after the -lnsl entry) so that they are picked up. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
