Hi,
I'm recompiling the amqssuba.c for use with MQI, with the following command as documented in q028350_.htm:
cc -maix64 -o subc amqssuba.c -I /usr/mqm/inc -L /usr/mqm/lib64 -lmqic
But I got the error: "collect2: library libmqic not found".
What is wrong here? All the paths are explicitly specified.
Thanks for sharing any insight.

| libmqic is part of the client install. |

Might also be worth noting that even if you want to run the application as a client (which we assume you do since you are attempting the link using mqic) that with newer versions of MQ (>= 7.1) you can link with mqm and make the decision in the code with MQCNO_ options (or just allow the MQ code to try local first and then client).
As Jeff hints, check that libmqic is indeed present, in case for some reason you don't have the client installed.
Cheers

thanks Jeff. I checked the installation, MQ Client is installed. Also the /usr/mqm/lib64 has all the libmqic*.a files. Even stranger is the same compile command using lmqm gets the same error, this time for libmqm:
"collect2: library libmqic not found".
I'm really lost by this. It seems something simple is missing.

Wow, this would be fantastic. Thanks for sharing this great new feature!
But first I have to figure out the cause of the current issue.

Are you sure you are using the XLC compiler? I thought "-maix64" was a gnu compiler flag.

Yes, -maix64 is for XL C compiler.
It turned out the documentation has a mistake in the syntax, there should be no space between the option -L and the library path.
cc -maix64 -o subc amqssuba.c -I /usr/mqm/inc -L/usr/mqm/lib64 -lmqic
It seems the space between '-I' and include path doesn't matter, but the one between '-L' and library path prevent the compiler from finding the path.
