[avr-libc-dev] [bug #17728] Errors building documentation in MinGW

[Joerg Wunsch]

Follow-up Comment #1, bug #17728 (project avr-libc):

If this is really the log from a pristine run (i. e. after a
"make clean"), there are several things fishy here:

make[4]: Entering directory `/c/avrdev/avrlibc/avr-libc/doc/examples/demo'
make[4]: Nothing to be done for `dox'.

(etc. pp.)

That's where the EPS versions of these image files are supposed
to be created.  Here's the extract from my log:

gmake[4]: Entering directory
`/home/joerg/src/avr-libc/doc/examples/largedemo'
jpegtopnm largedemo-setup.jpg |\
pnmtops -noturn -dpi 180 -equalpixels \
> largedemo-setup.eps
jpegtopnm: WRITING PPM FILE
pnmtops: writing color PostScript...
jpegtopnm largedemo-wiring.jpg |\
pnmtops -noturn -dpi 180 -equalpixels \
> largedemo-wiring.eps
jpegtopnm: WRITING PPM FILE
pnmtops: writing color PostScript...
jpegtopnm largedemo-wiring2.jpg |\
pnmtops -noturn -dpi 180 -equalpixels \
> largedemo-wiring2.eps
jpegtopnm: WRITING PPM FILE
pnmtops: writing color PostScript...
gmake[4]: Leaving directory
`/home/joerg/src/avr-libc/doc/examples/largedemo'

These Makefiles in the example subdirectories are static
ones, i.e. not created by automake.  Somehow, make must
have got the opinion everything has already been done.
Do these files (like largedemo-wiring.eps) exist at all,
maybe just in a different directory?

Otherwise, you probably have to run make in that directory
with debugging enabled, in order to see what it is going
to evaluate, and why it comes to the conclusion nothing
were to be done.

There's another strange detail in your log.  Doxygen starts,
and eventually spits out a number of messages like this one:

Generating page index...
Error: source ../../doc/examples/demo is not a readable file or directory...
skipping.
Error: source ../../doc/examples/largedemo is not a readable file or
directory... skipping.
Error: source ../../doc/examples/stdiodemo is not a readable file or
directory... skipping.

Maybe that's related?
