VIM: Configure script patch for IBM z/OS <<< gvim motif build procedure << motif 1.2 vs motif 2.1 <<

[Bovy, Stephen]

Author : Stephen Bovy

Background >>

Problems

1) The CFLAGS setting had syntax errors during the configure process ( need to remove "escapes" {\\} )
2) The configure process did not correctly detect missing header files {need to add option to force error on missing .h files haltonmsg(3296) }
3) New default Motif 2.1 support does not compile (need to externally change lib search paths ) (no change needed ) (see notes below )
4) New Default Motif 2.1 header detection creates compile and link errors ( need to remove most {Xm} headers )
5) configure CFLAGS value can-not be used for final config.mk

Here is the diff >>

After the above fixes vim can be built on z/OS using configure / make with (cc) (although the lib paths need to be changed )
I probably need to update the os-390 read-me and I also need to update config.in

Here are my .profile changes to the lib path ( to use old motif 1.2 files ) (with cc ) >>

tcpip=/usr/lpp/tcpip
xpath=$tcpip/X11R6
xsamp=$xpath/Xamples

export _CC_LIBDIRS="$xpath/lib $_CC_LIBDIRS"
export _CC_INCDIRS="$xpath/include $_CC_INCDIRS"

The final config.h output should look like this >>

If we can figure out how to get things working for motif 2.1 it would be really great, because then we

IBM supporting documentation >>

The X Window System toolkit includes files that define two macros for obtaining the offset of fields in an X Window System Toolkit structure, XtOffset, and XtOffsetOf. Programs written for, or ported to, z/OS UNIX MVS(tm) must use the XtOffsetOf macro for this purpose.

Porting Motif applications to z/OS UNIX MVS

Some Motif widget and gadget resources have the type KeySym. In an ASCII-based system the KeySym is the same as the ASCII character value. For example, the character 'F' has the ASCII hexadecimal value 46 and the KeySym hexadecimal value 46.

However, on z/OS UNIX MVS, the character value of 'F' is hexadecimal C6, while the KeySym hexadecimal value is still 46. Remember to use true KeySym values when specifying resources of type KeySym, whether in a defaults file or in a function call.

In some cases, an X Window System server may have clients that are not running on z/OS UNIX MVS. If a z/OS UNIX MVS X Window System application sends nonstandard properties that contain text strings to the X Window System server, and these properties might be accessed by clients that are not running on z/OS UNIX MVS, the strings should be translated. The translation should be to the server default character set before transmission to the server and to the appropriate host character set when retrieved from the server. This translation is an application responsibility.

Compiling and linking Motif and X Window System applications

The z/OS UNIX c89 or make commands should be used to compile and link X Window System and Motif programs. The following example shows how to use the c89 command to compile an X Window System program, xxx, which uses the Athena widget set, and create the executable file xxx. All code that uses the X Window System and Motif libraries must be compiled with the DLL option even if static linking is used.

Can you please make a context diff with diff -c or diff -u ?
Otherwise there might be mistakes.

I'm glad you managed to make it work. I wonder what the existing
configure lines were for. I assume your system is more recent, I don't
think these lines have been changed for several years.

Updating the os_390.txt file would also be very helpful for z/OS users.

[Bovy, Stephen]

The syntax error with (\\) was probably not-critical because setting the "float" option is probably not required.
The actual error was not detected because no one bothered to examine the configure script log.

There was one critical error False Detection of (xpm) {xpm] is not a Posix standard, therefore ibm does not support it
I added the header detection error flag to fix [xpm] { haltonmsg(3296) }

As I mentioned in previous emails the majority of { Xm } headers are Motif 2.1 which IBM previously did not support

I am not sure exactly when they added this new 2.1 support in ( I am currently using z/OS 1.10 or 11 )

Unfortunately IBM made Motif 2.1 the new default which requires using a much higher level of c standards compliant code

Compiling with the new motif 2.1 headers generates a boat-load of errors

So I inserted the old 1.2 headers back to the front of the bus (but that does not hide the new Xm headers )

So the configure script detected all these wonderful new Xm headers (some of which generated compile errors ) and after I hacked the code
To fix those errors I ended up with link errors because I was not and can-not link with the new motif 2.1 xm libs

So I added a new check to exclude the new Xm headers

Finally the configure script compile options are unique to the needs of the configure script and should not be used for the actual build process
Therefore I added a few new lines to set the correct options to be written to the make-file

Here is the diff you requested >>

The next challenge is to try to fix things so we can use the new 2.1 headers and the new 2.1 libs
