Problems installing dependency piqilib 0.6.6

[ghost]

Hi,

I was following the installation instructions using debian testing with ocaml 4.02.3 and wasn't able to build piqilib. I did a opam switch 4.02.1 and retried, but still no luck.

I'm currently stuck with the following error:

### stdout ###

there is already an outstanding bug at https://github.com/alavrik/piqi/issues/52, also someone else had the problem with BAP & piqi (https://github.com/BinaryAnalysisPlatform/bap/issues/323), the piqi project does not seem active anymore?

Any other version of ocaml I can switch to to get this working?

Thanks!

Hi,

I'm using Ocaml 4.02.3. But I have piqilib version 0.6.12 (and piqi in 0.7.4, opam 1.2.2). You seem to have piqilib in version 0.6.6. Could you try to update your version of piqilib ?

Regards

Ok, switching back wasn't possible since caml.inria.fr is unreachable, so I just removed ~/.opam and started fresh with the dist-ocaml 4.02.3. opam install piqi requires piqilib 0.6.6, I aborted that and went with opam install piqilib first, which gave me 0.6.12, and then installed piqi itself. Now I can proceed with gueb ;-)
