[Slackbuilds-users] [lramos.prof at yahoo.com.br: Re: Unison fails to build with OCaml 4.0]

Wed Oct 22 08:10:02 UTC 2014

Hello again,

I tried to redo this build, and it was successful.

However, I noticed a few problems in the file
01-change-ocamllibdir-for-ocaml-40.patch "inlined" in the mail body.
Mainly, the lines are truncated at some length, and this makes necessary
some work, because if the lines are simply extracted from the email, the
patch doesn't apply cleanly.

I remember to have hit problems with dllunix.so. I tried to simulate them
here again, but I couldn't, even reinstalling ocaml-4 again. My best bet
was that it was an issue of an ongoing move from 32 to 64; probably the
library which gave that error was a 32-bit version. I'm not sure about 
this, but it's my best guess.

I'll try to re-send those patches, but taking extra-care with maximum
line length. (Happen to need to learn how to do it with mutt/vi... yes, ":set textwidth=160")

Hello,

I'll check that, when some time is available.

I remember to have seen this message, and I did something to solve it.
Probably I concluded that it was a dependency issue, and didn't pay
much attention to it. But ultimately the package was built.

As a side note, I had some issues with unison version 2.40.63 (and
2.40.65) when trying to sync with other machines. As the other problem,
I don't remember the details, but what I found is that
the latest upstream version 2.4.102 solves this problem.

Please wait some more time and I'll check what I did to make to work
around that issue.


Thanks,

Luiz
