Unknown conversion type character 'z' in format about dans-gdal-scripts HOT 5 CLOSED

Joshua,

Type this:
CPPFLAGS="${CPPFLAGS} -D__USE_MINGW_ANSI_STDIO=1"
and then do "./configure" and "make". Let me know if that works.

I have not been able to reproduce this on my machine since I've been
unable to install GDAL under MinGW. Is there an easy way? The
instructions on the GDAL page are quite lengthy.

When compiling on Windows 7 (using mingw32) I get several warnings
like this:

|gdal_landsat_pansharp.cc:205:65: warning: unknown conversion type character 'z' in format

Once compiled the programs function normally, except where there
should be numbers in the output strings, eg:

|Output size is zd x zd x zd

Dan,

I didn't need to do anything special to build GDAL, other than using pre-compiled binaries for the Boost library. http://stackoverflow.com/questions/9598416/boost-binaries-for-mingw/9599214#9599214

Using -D__USE_MINGW_ANSI_STDIO=1 doesn't seem to have any effect, even though it looks to be the right thing to do. http://article.gmane.org/gmane.comp.gnu.mingw.user/27539/

From a small test program (I still haven't compiled GDAL), it seems
that with |-D__USE_MINGW_ANSI_STDIO=1 the warnings persist but the
program works properly. You can add the "-Wno-format|" flag to silence
the warnings if you wish.

Also, from what I read online (haven't tried it), MinGW-w64 fixes the
whole issue. If using the 64-bit compiler is an option then I would
highly recommend it. Large files (over 2GB) will not work properly with
the 32-bit version.

Let me know if these comments still do not solve the problem.

I had assumed the flag would prevent the warnings. You are correct - the program works correctly despite the warnings persisting.

Yeah, one would think. I discovered this only through experimentation.

Regardless of whether it works now, I still recommend MinGW-w64 if you
will be using files over 1GB in size. Unfortunately this would require
also recompiling GDAL and everything else connected to it as 64 bit.
