Support for libgdiplus on linux Ubuntu 18.04

[tecnike.net]

Hello

I'm trying to use Spire.PDF for .NET standard on Ubuntu 18.04 docker.

At the start of the Dockerfile I issue the following commands:

RUN apt-get install -y libgdiplus
RUN ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll

and I've already checked that libgdiplus is present in /usr/lib.

The project references the following nuget packages:

<PackageReference Include="Spire.PDF" Version="6.9.0" />
<PackageReference Include="System.Drawing.Common" Version="4.7.0" />

When I try to set the Text of a PdfTextBoxFieldWidget I receive the following error:

Unable to load shared library 'libdl' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibdl: cannot open shared object file: No such file or directory.

Do you have a solution to suggest?

Thank you in advance

Hello again

I already solved the issue by adding libc6-dev to the initial installs. The Dockerfile now contains the following lines:

RUN apt-get install -y libgdiplus libc6-dev
RUN ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll

And everything seems to work correctly.

Best regards
