You didn't link in the math library:

gcc -lm -osunmo sunmo.c

 

[godhelp]

gcc -lm -osunmo sunmo.c

I didn the ablve; still I am getting same problem. I have crosschecked mrelated lib files and confirmed ok.

any clue...

Are you trying to compile a Seismic UNIX program? That is the only place I find any information on some of the funtions you have listed. If so, there are special libraries used for this software. Is there a "Makefile" that goes along with your software package? If so, instead of running gcc on the program sunmo.c, run the command "make". You may have to modify the make file to use the gcc compiler instead of cc. If there isn't any makefile, you may have to set an environment variable called "LD_LIBRARY_PATH" with the library paths for this specific libraries in the software package.

Compiler command lines are order sensitive.
It's normal to list libraries AFTER source and object files.
[tt]gcc -osunmo sunmo.c -lm[/tt]

No luck..

we are in the process of creating another source..

Look in your software package directory for an include directory or a directory that contains header files (.h). Add the path to the include or header file directory in your path environment setting.
