I am trying to use cross platform version of the aspose library:
PackageReference Aspose.Slides.NET6.CrossPlatform 23.11.0
To create self-contained linux package
dotnet publish -r lin> ux-x64 -o …//linux-x64 -c Release --self-contained true -p:PublishSingleFile=true
Build process is outputing native linux library:
libaspose.slides.drawing.capi_x86_64_libstdcpp_libc2.23.so
But Running the self-contained library is failing with the next error:
System.DllNotFoundException: Unable to load shared library ‘libaspose.slides.drawing.capi_x86_64_libstdcpp_libc2.23’ or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibaspose.slides.drawing.capi_x86_64_libstdcpp_libc2.23: cannot open shared object file: No such file or directory

NOTE: library is search the liblibaspose.slides.drawing.capi_x86_64_libstdcpp_libc2.23.so
→ liblibaspose instead of libaspose
Adding path the library path export LD_LIBRARY_PATH=/home/site/wwwroot/tools/linux-x64 is not solving the problem.
