Hello,
I was using Graphviz 2.38 that has allready build exe-files.
I want to use the new realase, and saw that I have to build it myself.
I downloaded visual studio community 2019, and wanted to build it, but no succes…
Alway’s errors. I already set the include-file-directory, but is it only one?
Is it possible with 2019, or do I have to use 2014?
I’m not used to use visual studio, because I normaly create programs with BCC.
Thanks in advance

Hi,
I downloaded Visual Studio 2015. Also the files via the Git.
I folowed the instruction from [http://www.graphviz.org/\_pages/doc/winbuild.html](http://www.graphviz.org/_pages/doc/winbuild.html)
I still can’t build the dot.exe file. Do I have to do anything else?

Hi Marc. What errors are you getting? When you say you can’t build, what exact step is failing?
To set expectations, I think none of the maintainers of Graphviz have a Windows box or much experience with Windows, but we can perhaps walk you through debugging it?

Hello,
I want to build the dot.exe file.
If I build it with visual-studio, I get this error.
