x64
I am a software engineer with a passion for older home computers, and just recently started writing some simple programs in assembly for the C64.
I downloaded VICE and cc65, and compiled the sample programs. Most work well, except for the ones that make use of the TGI driver.

https://github.com/cc65/cc65/blob/maste ... /tgidemo.c

If DYN_DRV is set to 1, the program complains about not being able to load the driver. I suspect that I need to somehow make the driver’s object file available to VICE, but I don’t really understand how.

If I set DYN_DRV to 0, it runs just fine. I assume the driver is being linked into the final executable.

Can you help me figure out how to run TGI with a dynamically linked driver?

(I can't help - but welcome!)

The documentation is hard to follow for Dynamic drivers. It does look like you need a TGI driver file to be on your disk drive. That has to be compiled in a previous step but I could not find specific info on how to build that.

From what I can see, its an o65 formatted file with the TGI sources compiled.

There a copy of that file here:
https://sourceforge.net/p/cc65/activity ... 12560e4dd6

Look for the "TGI-preview-0.0.1.zip" file. The o65 file is labeled c64-hi.tgi

My SBC-3 had a custom TGI library but I used it statically. I never tried the dynamic load feature.

Good luck!

Sorry, I missed this!

Thank you for pointing me in the right direction!

I actually did not know about d64 files at all. I was just invoking the emulator as "x64 path/to/prg/file", which seems to implicitly create a d64 file with just that PRG.

Building my own d64 image with both files did the trick. Thanks again!

I'm glad I could help and that you got it working!
