In the netcdf package for mingw-w64, a patch is applied to the CMakeLists.txt file. To improve visibility of the changes involved, I am submitting the patch for inclusion in the netcdf source distribution.
Here is the original patch from MINGW-packages.
I have removed the definitions for variables
HAVE_WIN_TEMPandHAVE_WIN_SSCANF, which were used by other patches that are not required with the current netcdf master branch. I have also enabled the test formkstemp, which is provided by the current mingw-w64 header files.I have added the definition of preprocessor macro
__USE_MINGW_ANSI_STDIO, which enables support for ANSI standard format specifiers inprintfand related functions, so that tests ofncdumpandncgendo not fail with incorrectly formatted output.I have also added a compiler flag (where supported) so that
__FILE__macros are converted to relative paths. Packages for mingw-w64 are required to be relocatable, and warnings are produced when building packages that refer to the absolute location of the build directory. The warnings are avoided by using relative paths in compiled objects. (Absolute paths in text files are replaced as part of the mingw-w64 package creation step).
