Re: [Pharo-project] LibGit2 bindings with TalkFFI (was: Screencast: Creating C library bindings with TalkFFI for libgit2)

by Ciprian Teodorov

Its strange because with the checkout of libgit2 that I did yesterday I did not have this messages. I was having some - type not found. You should not take the compilation results as reference, since the makefile will have all compile options set correctly, and probably it will use GCC for compilation. You should try to see what are the options that need to be passed to clang, when compiling the header. Looking at the makefile can be a good starting point. I'll try to have a look at this, to identify the correct options.

Indeed, this looks like an issue with my libclang mapping. Version 1.3 of talkffi does not have this problem since the clang diagnostics are not used.

If ZnUrl is fantastic, and general, and permits separate packages to add capabilities (supporting SIP URIs, for instance), then it sounds like just the thing to take as the gold standard.

Who know maybe you and Igor turn out to be best friends. I had a physical fight with my best friend and we have been unseparable ever since for 19 years now and till this day he has the art of annoying me deeply :D But there is more to people that meets the eye, a lot more.
