Mixing ANSI C and aC++ compilers

[Mixing ANSI C and aCC c]

If anyone has linked a shared library with the C program using ANSI C compiler on HP-UX and getting following types of errors while running the executable created

To resolve this type of error, check if shared library you are using is created using aCC compiler. If libraries are created using aCC compilers then there are three ways to solve the problem.

1. Use aCC compiler for the linking.
2. If you still want to continue with the ANSI C compiler then

a.out must be linked with the HP aC++ runtime libraries in the following order:
-lstd -lstream -lCsup -lm -lcl -ldld

To better understand read the following link http://docs.hp.com/en/4311/distributing.htm

3. Use LD_PRELOAD command to preload the libraries mentioned in option 2 (lstd -lstream -lCsup -lm -lcl –ldld

). But LD_PRELOAD option if set in .profile may affect other programs. So better use it while running the program creating problem.

Hi ??

Welcome to the OpenVMS forum, the forum that deals with the most wonderful OS on the world!

Now, in VMS that would be an easy question, but you asked:

>>>
If anyone has linked a shared library with the C program using ANSI C compiler
!!!
on HP-UX
!!!
<<<

and I think the answers you will get in the HPUX forum would be much more specific to your situation!

Proost.

Have one on me.
