Unable to Load Shared Library ‘libaspose.slides.drawing.capi_x86_64_libstdcpp_libc2.23’

Aspose.Slides Product Family

We are also having problem running Aspose 23.2 or 23.3 (eg, a version after .NET 6 support was added).

With 23.1 and earlier we’ve used the following docker file to run our aspose.slides application (not relevant parts of the file missing in the example below):

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS runtime
RUN apt-get update -y && apt-get install -y apt-utils
RUN apt-get install -y libgdiplus && apt-get install -y libc6-dev

… other docker related things here not relevant to the issue

When using 23.2 or 23.3 we get the following run time error:

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 using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable:

HI @andrey.potapov
Using version 23.4, for some ppt files, this problem still seems to exist (.net 6.0 platform), in Linux environment (windows has no problem).

@Kyrie,
Our developers have investigated the case and found that the Docker image is missing some libraries (libfontconfig.so.1, libfreetype.so.6, libexpat.so.1, and libpng16.so.16) that are used by Aspose.Slides. These libraries can be installed with the following packages: libfontconfig1, libfreetype6, libexpat1, libpng16-16.
Here is an example command for the Dockerfile:

#Install the necessary libraries for Aspose.Slides under .NET 6.0 and .NET 7.0, which may be missing in the Docker image
RUN apt-get update && apt-get install -y \
 libfontconfig1 \
 libfreetype6 \
 libexpat1 \
 libpng16-16

Please add these commands to the Dockerfile to ensure that the necessary libraries are installed.
