wcs2kml / cygwin64 / compile error /need Help

[Jean-Paul Godard]

Hi all,

I'm trying to compile Wcs2kml with gflags 1.5 on a cygwin64 environment ...

remains following errors (after some update for deprecated statements )

Any Hint?

make[4]: Entering directory '/opt/wcs2kml/src/google'

/bin/sh ../../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I../../src -I../../src -I../../src/google -I../../src/google/libwcs -g -O2 -Wall -MT pngimage.lo -MD -MP -MF .deps/pngimage.Tpo -c -o pngimage.lo pngimage.cc

I vaguely recall having problems with wcs2kml -- IIRC I had to get the svn / hg / whatever development version?

I made some modifications in :

pngimage.cc

stringprintf.cc

to fix the problems:

1 - As specified in libpng manual:

The png_info structure is designed to provide information about the PNG file. At one time, the fields of png_info were intended to be directly accessible to the user. However, this tended to cause problems with applications using dynamically loaded libraries, and as a result a set of interface functions for png_info (the png_get_*() and png_set_*() functions) was developed, and direct access to the png_info fields was deprecated..

2 - Adding #include <cstdio> to stringprintf.cc fixes problems.

Updated files  are attached for help.
