Hello,

I have to compile libpng (libpng-1.5.14) which is required for WRF. I end up on this error:

make all-am
make[1]: Entering directory `/home/wrfcomp/WRF.3.4.1.ARW.pgi/libpng-1.5.14'
source='png.c' object='libpng15_la-png.lo' libtool=yes \

libtool: compile: pgcc -DHAVE_CONFIG_H -I. -DPNG_CONFIGURE_LIBPNG -g -c png.c -MD -fpic -DPIC -o .libs/libpng15_la-png.o
PGC-S-0240-Unmatched #endif (./pngpriv.h: 1740)
PGC/x86-64 Linux 13.1-1: compilation completed with severe errors

I checked the .h and i can't find any unmatched #endif

Neither gcc/gfortran (4.4.6) or intel (13.0.1) fail on this compilation.

Plateform is linux centos 6.2 x64

Any idea ?

Regards,

Arnaud

Hi Arnaud,

The problem here has to do with how the file "pnglibconf.h" is getting generated. Our preprocessor will put a space between a "*" and "/" unless it's the end of a comment. The authors aren't expecting this, hence when they preprocess the following line from "scripts/pnglibconf.dfa"

Thanks for the quick answer. I will try to report back to libpng people and try to find a fix.

Thanks.

Arnaud
