+Below are install instructions for os/390 2.5 & below and
+for os/390 2.6 & above. The basic reasons for exporting
+the LIBS and CFLAGS variables is to get the configure
+script to run properly under os/390. configure, when
+checking for X, attempts to compile a program something like
+
+ int main() {
+ XtMalloc()
+ ; return 0; }
+
+using 'cc -o conftest conftest.c -lXt'. However this results
+in a number of linkedit messages such as:
+
+ IEW2456E 9207 SYMBOL xcatd UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE
+ DESIGNATED CALL LIBRARY. NAME SPACE = 3
+ IEW2456E 9207 SYMBOL XrmQGetResource UNRESOLVED. MEMBER COULD NOT BE INCLUDED
+ FROM THE DESIGNATED CALL LIBRARY.
+ IEW2456E 9207 SYMBOL XrmGetDatabase UNRESOLVED. MEMBER COULD NOT BE INCLUDED
+ FROM THE DESIGNATED CALL LIBRARY.
+
+The only way I can get this program to compile and link is to
+use 'cc -o conftest conftest.c -lXt -lX11 -lSM -lICE'.
+With os/390 2.6 and above, IBM has provided X functions in dlls;
+this is the reason for the separate install steps. In fact,
+trying to use the X archive files (eg -lX11) when linking xterm
+results in an abend0C1 in low storage when X tries to call the
+initialize function (at least on my system). This has something
+to do with the calling X routine thinking it has a function pointer
+descriptor (c++) when it actually has just a function pointer (c).
+Unfortunately, I have been unable to recreate the problem in a
+simple testcase, so I haven't reported it to IBM. Anyway, for os/390
+2.6 and above, configure will build a Makefile with the following line:
+
+ 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
+
+The '-lXaw -lXext -lXmu -lXt -lSM -lICE -lX11' should be manually removed;
+this isn't strictly necessary, but will reduce the size of the executable
+by about 4M.
+
+The '-Wl,EDIT=NO' causes the Binder to produce a non-editable executable,
+dramatically reducing the size of the executable file.
+
+Good Luck!!

+ cd xterm
+ export LIBS='-lXt -lX11 -lSM -lICE'

+------------------------------------------------
+ gunzip xterm.tar.gz
+ pax -o from=ISO8859-1,to=IBM-1047 -rf xterm.tar
+ cd xterm
+ ./configure # LIBS, CFLAGS, and CC are defined by configure for os/390 2.6.
