OpenGL Font in 64-bit application

[dannycat]

I am have difficulty in getting OpenGL to display text in the 64-bit version of a program. They are fine in the 32-bit version. In a previous post I mentioned that the fglCallLists routine was not yet defined correctly in ifopngl module and Steve L provided a workround by defining a custom interface. See font.f90. Unfortunately this does not seem to work as the text is displayed as strange, mostly non-text type, symbols. The gp%fbase contains the result of the fglGenLists() function. Either the string is not being passed correctly or the base address is incorrect (or something else even). I have not changed any variables from default integer*4. Should fglGenLists return a integer(HANDLE) rather than integer*4?

Any help would be appreciated.

fglGenLists returns a "UINT" which is integer(4), so whatever the problem is, it isn't the return value. It isn't the type of the argument, either, which is a GLSizei or integer(4). In OpenGL, the display list identifiers are just integers, not address-sized handles.

Where are you passing strings? Can you show some sample code?

Hi Steve, Can you open the attached font.f90 file (It is within the body of text)? This includes the workround you suggested previously when I was simply getting the code to compile and gets called whenever I want to output a string of text.

Sorry, I didn't realize that was the sample program.

Is that definition of oglCallLists really what I provided you? If so, my apologies as it is not correct. Please replace this:

integer(K_GLVoid),dimension(*) :: lists
!DEC$ ATTRIBUTES NO_ARG_CHECK,IGNORE_LOC :: lists

with this:

integer(K_GLVoid) :: lists

Thanks Steve, that works now.
