Well, if you're falling through the for() loop below, it means
that your font name isn't matching. In the builtin case, its
not supposed to be a path, just a simple text string. Stick
some printfs in the loop to see why the match isn't matching.
Make sure your name is specified in genfont.c.
Also, you could always return &pf[0] rather than 0 in the
non-match case, that will get you the first builtin font.

Perhaps I'm misunderstanding this but for these fonts, which are fixed size,
I assume the
height will be 0. correct? as in
GrCreateFont(FONTNAME, 0, NULL);
I'm getting a segfaule because the GdCreateFonts returns 0 at :
/* check builtin fonts first for speed*/
if (!height && (fontclass == MWLF_CLASS_ANY || fontclass ==
MWLF_CLASS_BUILTIN)) {
for(i = 0; i < scrinfo.fonts; ++i) {
if(!strcmpi(pf[i].name, fontname)) {
pf[i].fontsize = pf[i].cfont->height;
pf[i].fontattr = fontattr;
EPRINTF("1 createfont: (height == 0) found builtin font %s
(%d)\n", fontname, i);
return (PMWFONT)&pf[i];
}
}
/*
* Specified height=0 and no builtin font matched name.
* if not font found with other renderer, no font
* will be loaded, and 0 returned.
*
* We used to return the first builtin font. If a font
* return needs to be guaranteed, specify a non-zero
* height, and the closest builtin font to the specified
* height will always be returned.
*/
}
Any size I use returns "not found". Am I using this correctly?
