Hello Tomas,
I continued yesterdays work by taking the path of building xcircuit
using a mingw64 gcc compiler.
It is rather untested but works better than my previous build. (Can now
add more than 30 caps:) I know at least one error: Can't import a
background ps-picture.
The background postscript rendering has always been flaky at best. I
have long ago stopped using it and instead convert to a graphics image
and import, because it's more reliable. So it is not necessarily a
porting issue.
It's flaky enough that I should probably separate out the feature
with #ifdef...#endif blocks and disable it by default in the configuration.
I will try out some tutorials and then come back with some info. At
least this build process is far simpler then the one using the Windows SDK.
That's good to know.
Perhaps the 64-bit target is a too big step to take at the moment.
Perhaps the mingw32 environment is simpler. I have spotted a potential
issue with casting (void*) into (int). This is ok when (void*) is
32-bits but...
Patch to 3.7.37 is attached.
Most of xcircuit should be 64-bit clean, because I regularly compile
and run on my 64-bit systems (Intel Xeon and Core). Only in occasional
spots may the casting be dependent on a value not being outside of the
32-bit range, as with the "clientdata" pointer in events.c that was at
the top of your patch (which should be okay; it just casts the
32-bit integer "keywstate" into space occupied by a pointer, and then
casts it back again. The only reason for it is to conform to the
clientdata record used by XtAppTimeOut in the Xt library, or
Tcl_CreateTimerHandler in Tcl/Tk.
I tested your patch and added a test for "unsigned long long" in
configure.in, or else your patch breaks the standard Linux "make"
process. Otherwise, the patch looks okay, and I uploaded it to
the git repository on opencircuitdesign.
