Hi Greg,
thank you for your post. I have to say after you explained how complex the
blit support with a screen driver for 0.92 would be I tried to write one for
the Snapshot version. I used MWPF_TRUECOLOR565 and got it to work! The
samples work just as they did before with 0.91.
On the other hand, could you please explain how to get the printf, dprintf,
eprintf, fprintf commands to write to a file? If these would print/write to
STDOUT, I could redirect them on the start of the program. The changes I
tried in the error.c files did not seem to work.
I also tried to set HAVE_FILEIO=1 but that did not seem to cause a file to
be opened and the messages were still send to the screen. What is the name
of that file and how do I open it?
When should I set -DHAVE_FPRINTF=1?
Georg
