C fatal error: 'Xm/Xm.h' file not found , motif installed

Hello,
i have installed open-motif -2.3.8_1 X11 Toolkit on freebsd32bit machine.
wanna compile a little script. script is ok. already compiled on other machine (linux)
the message is as follows
Code:
cc -o button button.c -lXm -lXt -lX11
button.c:3:10: fatal error: 'Xm/Xm.h' file not found
#include <Xm/Xm.h> /*Motif include file*/

1 error generated
$

How can this be possible if open-motif is correct installed ?
there are only two other motif packages.
1. linux-c6-openmotif
2. linux-c7-motif
but that are onlylibraries for linux support.
normally the main motif library from UNIXBSD should run.
freebsd32bit is up to date.
xorg installed. xfce desktop is working.
i only want to compile this damn C - Motif script. nothing else
Then Coffee and Relax.
The Xm/Xm include file is the main include file in Every script.
Impossible to be not there.

Attention : i found another error on a different compilation.
X11/Intrinsic.h NOT FOUND

if it gets put in the includes on FBSD then try this on your line
Code:
cc -L/usr/local/lib -I/usr/local/include -o button button.c -lXm -lXt -lX11
 
hey man , yes that works. i checked out on two scripts.
how do you know that ?
what can i do more to fix my motif installation ?
have i done something wrong in the installation ?

many thanks.

I do not think so, I had to find this out too, coming from Linux. I just add that to my command line and makefiles when I compile in FreeBSD to what little I do, and it works.
 
userxbw ,
yeah i want to program in C with Motif on native unix. not Gnu-Linux.
The original System-V unix.
Have some code ready and it works.
I stay on freebsd. nothing else.
 
I do not know all of the nuts and bolts of how to with clang and FreeBSD. All I've ever done is take my stuff I wrote in Linux, and someone else's source code for some stuff I use and made it work in FreeBSD too.
If you just stick with FreeBSD then of course over time will/should get to know what to do to get your C code to work. for that one partt just remeber to add your -L/usr/local/lib and -I/usr/local/include and what ever else and if everything is written as it should be then it will work.
 
Ports and packages in FreeBSD are installed to /usr/local.

So it makes sense that includes are in /usr/local/include and libs are in /usr/local/lib.

By default the compilers do not include these paths by default (similar that on Solaris, suncc doesn't include things from /opt/csw, /usr/sfw, etc).

The -L/usr/local/lib -I/usr/local/include compiler flags simply add these two directories to search for libs and includes respectively.

if you use CMake or Autotools, this isn't necessary because these tools include these paths.
