Openmotif toolkit!

Applications Programming
1

I'm using ubuntu 9.10 as OS and i installed a toolkit of widgets: openmotif.
The packages are: libmotif3, libx11-dev, libxp-dev, libxt-dev, x-dev. How can I compile a program including the MOTIF toolkit?

I tried:

gcc <my_file.c> -L /usr/lib/

It doesn't work

I don't know very much the linking process of C, and I'm not an expert of GUI creared by this wonderful programming language, but i want to learn.

Someone help this poor newbie! Thanks for all answer! :slight_smile:

-L only tells it where, not what. Try -lXm

I wonder what does that mean? What do the error messages say?
How does your code look like?
I guess you include Xm.h and/or XmAll.h header files?
Those should be located in /usr/include/Xm
You'll want to check the Programmer's Guide too:
Open Motif - Documentation Supplement

Excuse for the late answer..... :o

I solved! I have to add -lXm (as you said) and -lXt -lX11
I can compile the programs now.

I'm off-topic, but i did not open a new thread....

Where can I found documentation about motif? I downloaded the manuals, and i'm learning some ancients tutorial that I found; but I havn't a complete guide.

Where you learned motif? Can you suggest me a book

Thanks in advance for any reply! :slight_smile:

no.
documentation is very scarce.

the man pages aren't too bad.
you will need to get used to trawling through the header files too.
there are lots of typedefs.

e.g: man XtIntervalId will say:

   XtIntervalId XtAddTimeOut(unsigned long interval, XtInputCallbackProc
              proc, XtPointer client_data);

what the hell is the correct prototype for an XtInputCallbackProc? I hear you cry. So you need to
grep the header files until you find the typedef

Intrinsic.h on my BSD

typedef void (*XtInputCallbackProc)(
    XtPointer           /* closure */,
    int*                /* source */,
    XtInputId*          /* id */
);

there are some design aids for building the interface:
there is Xdesigner which used to come with the
Sun Studio, though i never got it to work on linux.
and dtcreator used to exist on solaris for
the CDE environment.
but all pretty much ignored.

I gave up on X because designing interfaces is boring without a graphical tool.
I can recommend fltk which has fluid as a lightweight X environment
for knocking up nice little apps without massive Qt GTK dependencies.

Thanks! I'll try what you suggested!

Thanks again! :slight_smile:

PS: Other suggestions are welcome!

EDIT:

What do you think about wxMotif?

THANKS!

never tried wxmotif.

it looks worth a look to me though.
it makes life easier having a form designer.
it's very tedious doing it by hand.

why motif particularly?
motif is a bit of a backwater now, in this millenium.
