It looks like you are not picking up the type definitions from the /usr/include/security/pam_appl.h file.

What do you mean--I am not a "C" guy.

It looks like everytime there is an * in a declaration, gcc doesn't like it--the following is an excerpt from pam_modules.h

extern int
pam_sm_authenticate(
pam_handle_t *pamh,
int flags,
int argc,
const char **argv);

gcc is not complaining about the "*". It's complaining that it doesn't know what a "pam_handle_t" is. This structure is defined in the /usr/include/security/pam_appl.h file.

If you are using a Makefile, then try and find a line in it that contains the string "-I /usr/include" and append "-I /usr/include/security" to it.

If you're running gcc from the command line, then try,

# gcc -I /usr/include/security -Wall -fPIC -c pam_radius_auth.c -o pam_radius_auth.o

Richard,

Can you point out which line is #19 in the pam_modules.h snippet that you included?

I believe that Jim is suggesting that the pam_handle_t typedef isn't being defined prior to it use in pam_modules.h.

So you'll have to find which header file defines pam_handle_t and make sure that it gets included before pam_modules.h.

I wish I could be more help, but I haven't built this package myself.

Line 19 is:

pam_handle_t *pamh,

from the above snippet.

Jim,

I added the -I/usr/include/security and got the same results.

Ok, try this then:

Modify /usr/include/security/pam_modules.h
by adding on line 5 the following,

#include

*** Caveat, this modification is unlikely to be supported by HP, but I think it should work to get the needed type definitions.

Unfortunately, you may need to go back to wherever you got this source code in order to "fix" your remaining problems. I don't have any experience with programming the PAM stuff, and the remaining errors appear to be syntax related.

I would imagine that the source code you're trying to compile came with several different README's and maybe an INSTALL file. I would look through these carefully to see if they have any pointers on compiling your source under HP-UX.

Jim:

Thanks for trying. Unfortunately, I got the source from freradius.org and they said that the only thing it had been used on was Red Hat and Solaris. No one was interested in HP-UX.

Hi!

I don't know if it will work, but you can try this.
Change following part in pam_radius_auth.h:
#ifdef sun
#define PAM_EXTERN extern
#define CONST
#else
#define CONST const
#endif
---->
#define PAM_EXTERN
#define CONST

Hope this helps a little bit,

Thomas
