SQLite Forum

How do create the neat flow diagrams for SQLite?
I downloaded the tarball and got the source. I am on W10 so not unix. I installed Linux Ubuntu package, so I have bash. Now I'm trying to build your stuff so I can see how it works (it's not simple). I get an error on the build no matter what make target I use:

$ make schema
make: *** No rule to make target '../sqlite/src/test_md5.c', needed by 'tclsh.docsrc'.  Stop.

Where is test_md5.c?
