First of all, thanks for porting xview. It will be very useful for some old Solaris applications that we still use in our lab.
I'm having trouble compiling any xview applications, however. I get the following error message with all of the programs I've tried so far:
gcc -O2 -I/usr/openwin/include -L/usr/openwin/lib -I/usr/X11R6/include -L/usr/X11R6/lib -g -DLINUX -c disp.c
In file included from /usr/include/sys/ucontext.h:31,

/usr/include/ucontext.h:48: error: parse error before '}' token
*** Error code 1
Stop.

I assume that there is a simple workaround, but I haven't been able to figure it out.
Thanks.

You're welcome.
A significant financial contribution for the Xview work was made by member benker.
The "-DLINUX" shouldn't be used (you're not on a Linux machine).
I'd suggest adding "-D_ALL_SOURCE" to your compiles.
That will clear this up since 'stack_t' is guarded by _ALL_SOURCE.
I've built several Xview applications that do include <xview/xview.h>
which is at the head of the include file cascade the error output has.
These apps are the ones that are part of the Xview toolkit and others (i.e. jove).
There wasn't a problem as you have quoted when "-D_ALL_SOURCE" is used.

The -DLINUX was an artifact from when the code was ported from Solaris to Linux. I've removed that to avoid confusion.
The -D_ALL_SOURCE fixes the problem, but I still get a link error at the end:
> g++ -o disp disp.o bilinear.o event.o panel.o files.o help.o image_procs.o io.o -O2 -L/usr/openwin/lib -L/usr/X11R6/lib -D_ALL_SOURCE -lxview -lolgx -lX11 -lm

/usr/openwin/lib/libxview.a(ndet_loop.o)(.text+0x3f8):ndet_loop.c: undefined reference to `_svc_fdset'
/usr/openwin/lib/libxview.a(ndet_loop.o)(.text+0x45f):ndet_loop.c: undefined reference to `_svc_getreqset'
collect2: ld returned 1 exit status
Should I be linking to some other library to resolve these two symbols?

You need to link with the RPC library: "-lrpclib"
All of the svc API's are in the RPC library. You can read about them on
the "rpc" manual page (man rpc).
