[gdal-dev] GDAL conda build

[Jon Morris]

I've been trying to build a Windows conda package for GDAL 3.1.4, but am having problems with the poppler headers. I'm using the conda-forge recipe, which includes a line in the build script to detect the poppler version.

FOR /F "tokens=1,2 delims=." %%a IN ("%poppler%") DO (
  set POPPLER_MAJOR_VERSION=%%a
  set POPPLER_MINOR_VERSION=%%b
)
https://github.com/conda-forge/gdal-feedstock/commit/320e66064c1288d582a3cadd8b573c863af654d6#diff-6f4a4b77035617ba53fd8a4d15347c44bb89f09d8086a0ffc1a5fca230ae2ed5R16

This doesn't seem to be working, as when we get to compiling the pdf driver, the headers are missing.

(gdal314) %SRC_DIR%\frmts>cd pdf   && nmake /nologo /f makefile.vc   && cd ..   || exit 1
        cl   /nologo /MP4 /MD /EHsc /Ox /FC /D_CRT_SECURE_NO_DEPRECATE /D_CRT_NONSTDC_NO_DEPRECATE /DNDEBUG /W4 /wd4127 /wd4251 /wd4275 /wd4786 /wd4100 /wd4245 /wd4206 /wd4351 /wd4611  /DHAVE_SSE_AT_COMPILE_TIME /DHAVE_SSSE3_AT_COMPILE_TIME -I..\..\port -I..\..\ogr -I..\..\gcore  -I..\..\alg -I..\..\ogr\ogrsf_frmts  -I..\..\gnm -I..\..\gnm\gnm_frmts -I..\..\apps /DHAVE_AVX_AT_COMPILE_TIME -I..\vrt -I..\mem -I..\..\ogr\ogrsf_frmts\mem  -DPOPPLER_MAJOR_VERSION=0 -DPOPPLER_MINOR_VERSION=23 -DHAVE_POPPLER    -DGNM_ENABLED  -DGDAL_COMPILATION -DNOMINMAX /c pdfdataset.cpp pdfio.cpp pdfobject.cpp pdfcreatecopy.cpp ogrpdflayer.cpp pdfwritabledataset.cpp pdfreadvectors.cpp pdfcreatefromcomposition.cpp

c:\bin\anaconda3\conda-bld\gdal_1604943770331\work\frmts\pdf\pdfsdk_headers.h(54): fatal error C1083: Cannot open include file: 'goo/gtypes.h': No such file or directory (compiling source file pdfdataset.cpp)

In pdfsdkheaders.h we can see it's the wrong poppler version that's causing the error:

#if !(POPPLER_MAJOR_VERSION >= 1 || POPPLER_MINOR_VERSION >= 73)
#include <goo/gtypes.h>
#else
typedef unsigned char Guchar;
#endif

The installed version of poppler is 20.11.0, so I don't know why I'm getting major version set to 0 and minor version set to 23.

I'll also ask over at conda as this is most likely a conda build problem, but I thought I would also ask here if anyone has successfully built a conda package and knows how to get this recipe working.

Many thanks!
