Hi all
I am trying to port some open source C code that compiles fine on both Windows C and gcc. I am trying to port it into native z/OS C.
I compile using:
//STEP1 EXEC EDCCLG,CPARM2=SOURCE
The compiler is:
15647A01 V2 R10 OS/390 C
Concatenated header library:
//SYSLIB DD
X/SYSLIB DD DSNAME=&LIBPRFX..SCEEH.H,DISP=SHR
IEFC653I SUBSTITUTION JCL - DSNAME=CEE.SCEEH.H,DISP=SHR
// DD
X/ DD DSNAME=&LIBPRFX..SCEEH.SYS.H,DISP=SHR
IEFC653I SUBSTITUTION JCL - DSNAME=CEE.SCEEH.SYS.H,DISP=SHR
// DD DSN=ZATLAS1.DEV.H,DISP=SHR

In the source code I have
#include "regex.h"

which I checked and is effective and recognized. Specifically I added at a certain point this code:
#if defined REG_DUMP
static int zatest (int c)
{return c;}
#endif

and then I did
int zosprivate = zatest(1);

with no issues whatever. The errors below must be because of some incompatible usage, but I do not know where to look (my C is pretty rusty and I am trying to improve it . Please see the errors and suggest where should I go from here.
Thanks
ZA

I get these errors:

Hello,

Where ae they defined/declared? They don't appear in the code

The headers are in the //SYSLIB DD, 3rd concatenation as I've mentioned

The relevant code in regex.h (or the REGEX member) looks like this:
/* regcomp() flags */
#define REG_BASIC 0000
#define REG_EXTENDED 0001
#define REG_ICASE 0002
#define REG_NOSUB 0004
#define REG_NEWLINE 0010
#define REG_NOSPEC 0020
#define REG_PEND 0040
#define REG_DUMP 0200

Hello,

Is it possible that the member is in one of the datasets earlier in the concatenation?

Thank you.
You were correct. I do not know how could I've overlooked this simple possibility.

Hello,

I do not know how could I've overlooked this simple possibility

Because you were so close to it. . .

Good to hear it is resolved. Thanks for the follow up
