Hi
I'm having trouble with the new versions of libpng (I think) my grabby
project (webcam utility) here http://tinyurl.com/2ulm8pw
It builds fine for 11.2 and SLE11 SP1, but I cannot figure out if it's a
code issue or a png.h issue. I'v removed all the Makefile items to
exclude the debug build.
Could someone look at the build log http://tinyurl.com/3xraaj7 and maybe
enlighten me as to where/what to do?

Ok,pngconf.h is included by picio.c on line 5, and then fails with
usr/include/pngconf.h:371:21: error: expected '=', ',', ';',
'asm' or
'__attribute__' before '.' token
Qquestion is what that line says exactly ? post your findings.

Hi
libpng12-devel-1.2.43-3.2 pngconf.h Line 371 says;
__pngconf.h__ in libpng already includes setjmp.h;
So as per the INSTALL doc referred to, I added a patch before png.h to
skip this check (#define PNG_SKIP_SETJMP_CHECK) and it now builds. I'm
no coder, so I guess I need to rtfm some more ;)
Thanks for the pointer :)

Something else is including setjmp.h , workaround looks fine to me, but
it is better remedy the root cause.

Hi
I did an fgrep on the src files and found no reference to setjmp? So it
must be calling from an picio includes?
picio.c:#include <stdio.h>

I changed the CFLAGS as suggested as well :)

if you stick a big "gcc -M picio.c" somewhere during %build you will
get the header dependency list.
anyway .. png.h looks quite hackish and this can be a bug.
Unless you app breaks in a fairly obscure way, I suggest to leave it as
is, ;)

passing -DPNG_SKIP_SETJMP_CHECK in CFLAGS will also help in case a
workaround patch is not what you want.
