[vlc-devel] vlc build problem ... recompile with -fPIC ??

[Lyndon Brown]

Hi,

I've been taking a break from VLC dev work for some months now, but as
I have a moment to spare, your mail and a lack of responses managed to
catch my eye, and some/most/all of the other devs will likely be taking
a short break themselves over this Christmas period, I'll jump in with
a little advice.

Firstly, as I learned the hard way myself not so long ago, it's not a
great idea to build in the root of the project directory; create a
'build' subdirectory, `cd` into it, then issue your `../bootstrap`,
`../configure` and `../make` (or `../compile`) commands from there.
You'll run into fewer issues this way, and it's also much easier to
nuke the build files and start over if you ever want/need to. However,
having already used build commands at the root, you'll want to reset
the project directory back to a fresh state first, which you could do
most easily either by deleting the entire project and re-cloning, or by
deleting everything in the project directory EXCEPT the (hidden) '.git'
folder and then opening the git tools and undoing all listed changes.

Secondly, why have you chosen to use `--enable-static`; it isn't
necessary for Linux. The main use of that, I believe, is for the
Windows build. I'm a Linux dev myself and I've never used `--enable-
static`; you might find that building simply works successfully if you
drop it. Use of this on Linux is possibly a rarely tested
configuration, thus you're more likely to run into unnoticed/unresolved
issues.

The error you've encountered looks to me like a bug in the vlc build
system. Bug reports are appreciated and should be submitted via the vlc
gitlab instance.

Good luck.
