Well, you didn4t miss something. But this problem is a generell
one, not a special XForms one. I did the following to solve this
problem and make it portable to other directory structures at
distribution time.
(1) I defined a default XPM path, relative to the binaries location
(2) I created an environment variable MY_XPM_PATH which, if set,
is used instead of the builtin default
(3) I created an application parameter "-p path" which overwites
the two previous settings, if given.
-----------------
Some code follows
-----------------
...
#include <getopt.h>
#define XPMPATH_VAR "XPMPATH"
#define XPMPATH "./xpm"
main()
{
int c;
char xpmPath[NAME_MAX];
...
/* If 'XPMPATH_VAR' is set in the environment, get it! */
strcpy(xpmPath, getenv(XPMPATH_VAR)?getenv(XPMPATH_VAR):"");
...
while ( (c = getopt(argc, argv, "b:d:D:hp:s:")) != EOF ) {
switch (c) {
...
case 'p':
/* If pixmap path is given as an option, get it! */
strcpy(xpmPath, optarg);
break;
...
} /* switch */
} /* while */
...
/* If neither the environment variable 'XPMPATH_VAR' */
/* nor the option "-p xpmpath" was given, use the default */
if ( !(xpmPath[0] != '\0') ) {
strcpy(xpmPath, XPMPATH);
}
...
} /* main */
HTH,
