[fpc-pascal] Implementing AggPas with PtcGraph

[James Richters]

>How did you build/get freetype.dll?

I don't know how it was built, I swiped it from the AggPas24-rm3.zip file and it seemed to work.
I did find msvcr71.dll by searching my entire development pc hard drive and found it in C:\Program Files (x86)\StarWind Software\StarWind V2V Image Converter\lib\ and  Transferred it to my laptop and put it in the same directory as my test program and now it's running fine.

Thanks for the advice, I will check it out.

How did you build/get freetype.dll? If it was built using Visual Studio, freetype.dll might have been linked against a newer C++ runtime such as msvcr71.dll that is not shipped with windows by default. You clearly need to deploy C++ runtime libs as well with your product.
You may benefit from such tool as a dependency walker (https://en.wikipedia.org/wiki/Dependency_Walker).
On linux you can just use ldd.

Hope this helps,

Stefan
