Need help compiling ansi c program on RedHat unix

Hi,

We are moving from a HP-UX system to a Linux RedHat system.

We have some ansi C / proC programs running and I have troubles to get them compiled on the new system.

To get it compiled I had to remove some flags and commands because they are not available on the new compiler like:
gcc +s option
-D_HPUX_API_LEVEL=20040821 option
chatr +s enable ctpdb
-lsql11 became -lsqlplus

One error remains but I get it compiled eventually:
ctp_str.h:69:5: error: unknown type name ‘BOOLEAN’
BOOLEAN ctp_maintain_gcns;

Eventually I get them compiled, but they crash every time the programs use a function that is extern (so not in the own *.pc member)
e.g. extern void ctp_gen_setup_test_flags
At runtime it just gives "memory fault"
Probably because I have no alternative for the chatr command and the +s flag...

Please advice on how I can get it compiled and running so that it is able to call the functions in external member.

I attach the original makefile that compiles the code on HP-UX, but not on linux, so that you can advice how the new makefile should look like.

Regards and thank you in advanced,
Tim

Ok fixed the ctp_str.h:69:5: error: unknown type name ‘BOOLEAN’ error by adding this to ctp_str.h:

#define BOOLEAN int
#define TRUE 1
#define FALSE 0

So only the external calling issue remains...

the makefile was not attached. please attach it between code tags.

extern void ctp_gen_setup_test_flags

void type is only valid as return value of a function prototype. so i assume the expression was not complete.

if a function is declared as extern, you need a second c source where the function is defined (... has an implementation). then both c files must be compiled and linked together. if the function comes from an external library, you must link against the library. also you should make sure that the ansi-c compiler was used for both your source and the object file or object library where the function was implemented. if one of those was compiled with a c++ compiler, it would not work. at least not without some wrappers that are matching c++ mangled function names to pure c names.
