Daniel, when I want to compile from windows using vcpkg I do: cd d:\Github\gdal <-- whereever you have the gdal code cmake -B build -S . -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Debug cmake --build build --config Debug
and make sure your environment variable PROJ_DATA is pointing to C:\dev\vcpkg\vcpkg\buildtrees\proj\x64-windows-dbg\data (perhaps there are other things) I hope it helps. ________________________________ De: gdal-dev <gdal-dev-boun...@lists.osgeo.org> de part de Andrew Bell via gdal-dev <gdal-dev@lists.osgeo.org> Enviat el: dilluns, 2 de juny de 2025 16:01 Per a: Daniel Perez Rodriguez <dpr.1...@gmail.com> A/c: gdal-dev@lists.osgeo.org <gdal-dev@lists.osgeo.org> Tema: Re: [gdal-dev] Linking issue in Windows Hi Daniel, Symbols that start with "__" are reserved for system libraries. It appears that you're not linking the C++ standard library or are linking with an incompatible version. GDAL requires C++17 support.

My name is Daniel (first message here) from Spain so I hope I can explain my problem properly. I am working in a C++ project, using gdal in Windows and getting it from vcpkg, using cmake and Visual Studio 2022. From the last days, after an update of my development machine I am having a blocking issue compiling the project, to be a bit more precise: a linking issue. Here is my configuration and at the end I will put the errors: DEVELOPMENT ENVIRONMENT: Microsoft Visual Studio Professional 2022 Version 17.13.6 VisualStudio.17.Release/17.13.6+35931.197 Microsoft .NET Framework Version 4.8.09032 Installed Version: Professional Microsoft Visual C++ 2022 ASP.NET<http://ASP.NET> and Web Tools 17.13.124.35287 Azure App Service Tools v3.0.0 17.13.124.35287 C# Tools 4.13.0-3.25167.3+73eff2b5de2ad38ec602c0a9e82f9125fb85992b C# components used in the IDE.
