[gdal-dev] About installing EXPAT

[Abel Pau]

Hi Stefan,
thanks for your answer.

I’ve installed vcpkg as you recommend. I followed the instructions of the web.
After I installed packages you comment.
It’s been needed to install phyton3 again cause some recent issues. (error: while looking for phyton:x64-windows: error: while loading phyton: error: phyton does not exist)
vcpkg install phyton3 works fine (it seems)

I Open Gdal CMakelists.txt in Visual
I add next two lines below (ODBC is not in vcpkg?)
list(APPEND CMAKE_PREFIX_PATH "C:/dev/vcpkg/vcpkg/installed")
set(ODBCCPP_INCLUDE_DIR "D:/GitHub-repository/odbc-cpp-wrapper/src")

It seems that all is fine. Visual detect it and execute the configuration.
1> [CMake] -- The following RECOMMENDED packages have been found:
1> [CMake]

After that i try to build the project and...

I have to install setuptools? At the end I don’t get the GDAL project rebuilded and I don’t know what is happening.
I’m new at that kind of things.
Thanks again for any help!

Hi Abel,

I can recommend vcpkg (https://vcpkg.io/) if you’d like to build GDAL on Windows with Visual Studio or Visual Studio Community Edition.

vcpkg builds packages from sources and can build the mandatory dependencies of GDAL (and a lot of optional ones). You get a working starting set via

vcpkg --triplet=x64-windows install curl expat geos lerc libdeflate libgeotiff libiconv libpng libxml2 openssl proj qhull sqlite3[rtree] xerces-c zlib

You can then open GDAL’s CMakeLists.txt file in Visual Studio via File -> Open -> CMake… After configuration, you can just start the build:

>------ Build All started: Project: gdal, Configuration: x64-Debug ------

  [2/1351] Building C object frmts\zlib\CMakeFiles\libz.dir\trees.c.obj
  [3/1351] Building C object frmts\zlib\CMakeFiles\libz.dir\uncompr.c.obj
...

  [1351/1351] Linking CXX executable fuzzers\tests\test_osr_set_from_user_input_fuzzer.exe

Build All succeeded.

vcpkg builds debug and release versions of the packages. As the packages are built from source, you can even debug into the dependencies because the source code is on your machine. That can be really helpful from time to time.

I’d recommend starting from a clean environment though. I guess you tweaked quite a lot to get GDAL building.

Cheers,
Stefan
