x64 debug build does not work at all.

[joycepg]

multiple issues. to reproduce, run settings.bat "BUILD_TYPE=Debug" "SKIP_FAILED_PATCH=true" "FASTBUILD=0" scripts\build I had to add the skip failed patches to even get started.

• zlib build failed on the masm step. I had to download a pull request off zlib github site for vc14.
• libpng build failed. i had to run path C:\Users\Paul\Documents\windows-builds\packages\zlib;%path% before running build.bat so libpng build would find zlib.dll
• i have sent a pull request for a fix to build_freetype.bat
• the .sln for expat has win32 references all through the x64 target, eg, it builds to ..\win32\bin\Debug\libexpat.dll. here is the warning from the build C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppBuild.targets(1189,5): warning MSB8012: TargetPath(C:\Users\Paul\Documents\windows-builds\packages\expat\lib...\ x64\bin\Debug\expat.dll) does not match the Linker's OutputFile property value (C:\Users\Paul\Documents\windows-builds\packages\expat\ win32\bin\Debug\libexpat.dll).
• gdal build fails, looking for win32 Release version of libexpat. double fail! here is the link command: link /nologo /dll /INCLUDE:OGRFeatureStylePuller /INCLUDE:OSRValidate /INCLUDE:OPTGetProjectionMethods /INCLUDE:OGR_G_GetPointCount /INCLUDE:OGRRegisterAll /INCLUDE:GDALSimpleImageWarp /INCLUDE:GDALReprojectImage /INCLUDE:GDALComputeMedianCutPCT /INCLUDE:GDALDitherRGB2PCT /INCLUDE:OCTNewCoordinateTransformation port.obj gcore.obj alg.obj frmts\o.obj ogr\ogrsf_frmts\ogrsf_frmts.lib ogr\ogr.lib legacy_stdio_definitions.lib "C:\Users\Paul\Documents\windows-builds\packages\expat"\win32\bin\Release\libexpat.lib "C:\Users\Paul\Documents\windows-builds\packages\libtiff\libtiff\libtiff_i.lib" C:\Users\Paul\Documents\windows-builds\packages\sqlite\sqlite3.lib odbc32.lib odbccp32.lib user32.lib ws2_32.lib gcore\Version.res /out:gdal200.dll /implib:gdal_i.lib /debug LINK : fatal error LNK1104: cannot open file 'C:\Users\Paul\Documents\windows-builds\packages\expat\win32\bin\Release\libexpat.lib' NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\link.EXE"' : return code '0x450'

@joycepg Debug builds are not maintained anymore (haven't cleaned up the scripts yet).

We've switched to "Release with debug symbols", as keeping up with the combinations of Debug/Release * x86/x64 * VS2013/VS2015 became too much of a hassle.

FYI: VS2013 support is also going to be dropped soon, as the tools (mapnik, node-mapnik, osrm, libosmium, ...) we build these dependencies for, use C++11 which isn't supported by VS2013.

ok, yes windows builds are way too complicated in general (static/dll, runtime static/dll, debug/release, x86/x64). fyi, i did get the x86 debug build to work ok. you have a pull request with the few minor changes if you want.

I'd rather not accept the pull request now, as I'm lacking bandwidth to support it properly.

However, I've created a ticket with ideas for further improvements.

Feel free to add anything you consider useful to add in future iterations: https://github.com/mapbox/windows-builds/issues/59
