Re: Tn5250 compile under IBM Aix 5.3

Hi again!
I've updated and configured again my PASE on the Iseries (V5R4M0) with GCC
4.0.0 (got from Yip)
So , compiling TN5250 i am having the same problems with snprintf etc..etc..
as shown before from James Rich.
I will try to find GCC 4.1.1 binaries, and then i will try again to compile
it.
There are any extra steps to follow? As i've already told it could be really
interesting to have it working on the Iseries PASE :-)
Ciao.
ALberto.

hi James,

My changes aren't exactly huge, so it probably doesn't matter which
method we use. I figured people would rather keep the structure
intact.

Seems to me, the problem is that we used pointers in our structure that
were the same name as the system APIs (accept and connect). When the
macro runs, it renames accept to naccept and connect to nconnect, and then
our code doesn't work anymore.

How else would you fix that? If you disable the macro, then it's calling
the wrong system API, right? Otherwise, you'd have to be careful to have
it enabled in some places and disabled in other places... which seems a
lot more complicated than renaming the pointers.

conf.c: In function 'tn5250_config_replacedata':
conf.c:716: warning: incompatible implicit declaration of built-in
function 'snprintf'

Hmm... I didn't get any snprintf, strncpy, strlen, strcpy or vsyslog
errors.

I did get this malloc one that you also describe:

ld: 0711-317 ERROR: Undefined symbol: .rpl_malloc

Do you have any of these errors? Did you pass any options to
./configure?
Do you have the following line in config.log or config.h:

#define malloc rpl_malloc

This appears to be caused by the fact that the AIX malloc() function is
not 100% compliant with the GNU malloc function. So autoconf creates that
macro to rename malloc to rpl_malloc with the anticipation that we (the
tn5250 project) will provide a function called rpl_malloc() that replaces
malloc() to make it GNU compatible.

As far as I can tell, the only difference between the GNU malloc() and the
AIX one is what happens when you try to call it as malloc(0). And tn5250
never does that -- so the difference doesn't matter to us.

So I just commented out that macro in config.h.

Maybe getpwuid() isn't working as expected?

No... it turns out my problem with .tn5250rc (which, I'm ashamed to say,
took me _hours_ to figure out) was due to the fact that my .tn5250rc was
in EBCDIC and of course PASE programs only understand ASCII.

But, tn5250 was reporting a spurious error of "file not found" instead of
telling me the actual problem. So... it took longer than it should've to
discover.

But at this point, I _do_ have tn5250 running successfully in PASE.
Well... sort of, anyway. It doesn't seem to accept any keyboard input,
and I don't know why. But it doesn't give me errors, and it displays the
sign-on screen without problems.

I'm running GCC 4.1.1 compiled for AIX 5.2. I don't remember exactly
where I got it, I've had it on i for years and years.. I probably
originally got it from UCLA's AIXPDSLIB.
