I have written a pli. the tasks which the system calls of my
application are declared in some .h file. i have also defined some
macros in the header file.

i wrote two pli that refer to diffrent functions declared in the same
header file. but two plis behave differently. the task to one pli is
available but not to the the other. although the macros are also
available to both PLIs
it flashes the folloing error at run time

ncsim: error while loading shared libraries: \
/home/monika/flexlm/flexlm/v9.2/machind/libpli.so: undefined symbol: \
lp_checkout

the lp_checkout is defined and resides in some binary files.

can any body help me to resolve the issue ??

Thanks and regards

Not sure if this answers your question, but this does not look like
a PLI issue per se. Check:

- Have you #include-d your .h files inside the C application file?
Strictly speaking, header files should not contain code, but mostly
macros or function prototypes.

- Have you compiled all the files containg your C functions?

- In the final compilation command, are you using a -lpli or similar
linking option for all of your libraries?

Thanks for your response
I think you are right. It seems that i am missing some file in the
linking process.
Following is the response to your suggestions

> - Have you #include-d your .h files inside the C application file?

the header file contains only the function prototypes and macros

>

The C-code resides only in the file that contains the source-code of
the pli routine

Wat do you mean by "final compilation command"? Moreover
I have used pliwiz to generate the PLI and am using NC-simulator. I
dont see any '-lpli' option in either NC or the makefile generated by
PLIWIZ.

Thanks once again

It seems you are compiling your code into a shared library
(/home/monika/flexlm/flexlm/v9.2/machind/libpli.so) by linking all
object files togther (this ist the 'finale compilation command). If the
shared lib is missing some symbols while loading at run time, you may
have forgot to add the .o file containing the definition of lp_checkout.
If you need further help to resolve the problem, drop me an email.

I have added all the required .a file. I am able to use some of the
tasks declared in some .h file, But for some of tasks the libpli.so
file fails.
