[gdal-dev] Can we build CSharp Bindings in GDAL v3.9.3 or later with DOT NET FRAMEWORK 4.8?

[Parveen Sharma]

Hello tamas

I am trying to build with these options

<arg value="-DBUILD_CSHARP_BINDINGS=ON"/><!-- C# Bindings-->
<arg value="-DCSHARP_LIBRARY_VERSION=netstandard2.0"/>
<arg value="-DCSHARP_APPLICATION_VERSION=netstandard2.0"/>


However, I am getting errors wrt to finding the executables like OGRInfo.exe etc among others

[INFO]      [exec]   -- Installing: C:/workarea/Source/gdal/build_Debug/install/share/csharp/OgrInfo/OgrInfo.deps.json
[INFO]      [exec]   CMake Error at swig/csharp/cmake_install.cmake:152 (file):
[INFO]      [exec]     file INSTALL cannot find
[INFO]      [exec]     "C:/workarea/Source/gdal/build_Debug/swig/csharp/OgrInfo/OgrInfo.exe":




My question : If I set CMAKE OPTIONS as shown to "netstandard2.0" then do i expect to see the EXEs getting generated as I understand that .NET STANDARD is just specification and not any runtime. Will these make any difference?

Best regards,

Hi,

You can let cmake to build the csharp libs for netstandard2.0  ("-DCSHARP_LIBRARY_VERSION=netstandard2.0") which makes it compatible with both the netframework and netcore versions.

Best regards,

Hello

I am trying to build GDAL CSharp bindings from v3.9.3 branch<https://github.com/OSGeo/gdal/tree/v3.9.3/swig/csharp>.

The documentation for v3.9.3<https://gdal.org/en/stable/api/csharp/csharp_compile_cmake.html#net-build-toolchain> states that it needs .NET 5.0 OR Mono

[cid:ii_1956ab8f04dcb971f161]

Question : Is it possible to build GDAL source v3.9.3 using DOT NET Framework 4.8 or less? I am using below flags BUT it seems the build process is attempting to look for only .NET SDK and not the DOT NET FRAMEWORK

      <arg value="-DBUILD_CSHARP_BINDINGS=ON"/><!-- C# Bindings-->
      <arg value="-DCSHARP_LIBRARY_VERSION=4.8"/>
      <arg value="-DCSHARP_APPLICATION_VERSION=4.8"/>


Does GDAL still support building CSharp Bindings with .net framework?

Please let me know.

Best regards,
Parveen
