Not able to compile C program on z/OS (USS)
Hi,
I having an issue while compiling a C program in USS (z/OS) machine.

I was able to create objest files (.o) from source (.c) files but when I try to create a binary file from the object files I am getting the below error.

Code:
$ cc util.o sock.o app.o -lnsl -o ptf
FSUM3067 The archive library nsl (libnsl.a) cannot be found.

Thanks,
Madhu.

It means what it says, it doesn't have -lnsl.

Do you really need -lnsl?

Hi,
Thanks for the reply.

Sorry, I am not much familiar with -lnsl is. I used it because, the same option is used while compiling the program in other unix boxes too.

When I remove the -lnsl option, I get the below errors

Code:
$ cc util.o sock.o app.o -o ptf

Hi,
I have added the arpa/inet.h header file and removed the -lnsl option.

Now, I am left with the below errors

Code:

Hello Madhu,

From the error, its obvious that you need the libnsl.a because code links against some routines from that lib. What I would suggest is that find that library (using find) and explicitly specify the lib in the compile option (with -L) to see if it works.

Code:
find / -type f -iname "libnsl.a"

From this if you get any results then do
Code:
$ cc util.o sock.o app.o -lnsl -o ptf -L<YOUR_RESULT>

If you are not able to find libnsl.a then locate it from similar architecture of compile it on your machine.

Thanks and Regards,
Gaurav.

Hi,
I was able to compile the code now.

I have removed "-lnsl" and included "arpa/inet.h" header file, which fixed the issue related to library.

By removing the "-o ptf" remaining issues were also resolved. But this created the binary as a.out and I have renamed it to ptf.


Thanks,
Madhu.
