| 3 | Below are install instructions for os/390 2.5 & below and |
|---|
| 4 | for os/390 2.6 & above. The basic reasons for exporting |
|---|
| 5 | the LIBS and CFLAGS variables is to get the configure |
|---|
| 6 | script to run properly under os/390. configure, when |
|---|
| 7 | checking for X, attempts to compile a program something like |
|---|
| 8 | |
|---|
| 9 | int main() { |
|---|
| 10 | XtMalloc() |
|---|
| 11 | ; return 0; } |
|---|
| 12 | |
|---|
| 13 | using 'cc -o conftest conftest.c -lXt'. However this results |
|---|
| 14 | in a number of linkedit messages such as: |
|---|
| 15 | |
|---|
| 16 | IEW2456E 9207 SYMBOL xcatd UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE |
|---|
| 17 | DESIGNATED CALL LIBRARY. NAME SPACE = 3 |
|---|
| 18 | IEW2456E 9207 SYMBOL XrmQGetResource UNRESOLVED. MEMBER COULD NOT BE INCLUDED |
|---|
| 19 | FROM THE DESIGNATED CALL LIBRARY. |
|---|
| 20 | IEW2456E 9207 SYMBOL XrmGetDatabase UNRESOLVED. MEMBER COULD NOT BE INCLUDED |
|---|
| 21 | FROM THE DESIGNATED CALL LIBRARY. |
|---|
| 22 | |
|---|
| 23 | The only way I can get this program to compile and link is to |
|---|
| 24 | use 'cc -o conftest conftest.c -lXt -lX11 -lSM -lICE'. |
|---|
| 25 | With os/390 2.6 and above, IBM has provided X functions in dlls; |
|---|
| 26 | this is the reason for the separate install steps. In fact, |
|---|
| 27 | trying to use the X archive files (eg -lX11) when linking xterm |
|---|
| 28 | results in an abend0C1 in low storage when X tries to call the |
|---|
| 29 | initialize function (at least on my system). This has something |
|---|
| 30 | to do with the calling X routine thinking it has a function pointer |
|---|
| 31 | descriptor (c++) when it actually has just a function pointer (c). |
|---|
| 32 | Unfortunately, I have been unable to recreate the problem in a |
|---|
| 33 | simple testcase, so I haven't reported it to IBM. Anyway, for os/390 |
|---|
| 34 | 2.6 and above, configure will build a Makefile with the following line: |
|---|
| 35 | |
|---|
| 36 | LIBS = -lXaw -lXext -lXmu -lXt -lSM -lICE -lX11 /usr/lib/Xaw.x /usr/lib/SM.x /usr/lib/ICE.x /usr/lib/X11.x -lcurses |
|---|
| 37 | |
|---|
| 38 | The '-lXaw -lXext -lXmu -lXt -lSM -lICE -lX11' should be manually removed; |
|---|
| 39 | this isn't strictly necessary, but will reduce the size of the executable |
|---|
| 40 | by about 4M. |
|---|
| 41 | |
|---|
| 42 | The '-Wl,EDIT=NO' causes the Binder to produce a non-editable executable, |
|---|
| 43 | dramatically reducing the size of the executable file. |
|---|
| 44 | |
|---|
| 45 | Good Luck!! |
