[app-misc/fzf]: ebuild request

[rdnetto]

Hi,
I'd appreciate it if you could add an ebuild for fzf. I've had a go at doing so myself, but it doesn't seem to follow the normal package layout for Go (the source is in a src subdirectory), and I didn't know enough about Go to make it half-work without some truly terrible hacks.

[Dr-Terrible]

Sure thing. I'll give a try right now.

[Dr-Terrible]

There is now a preliminary ebuild with commit 596320e.
Let me know if there are missing parts, or if the ebuild needs to be further tweaked for specific features ;)

[rdnetto]

Awesome, thanks for that. It doesn't seem to be compiling for me though - looks like linking against ncurses:6 fails.

Hi @rdnetto.

I tried to reproduce your compilation issue, but without success. I don't have a file called /lib64/libtinfo.so.6 in any of my Gentoo/Linux systems, which is quite suspicious.

Please, can you paste me the output of this command?

qfile /lib64/libtinfo.so.6

and if qfile pinpoints a specific package, can you paste me the output of emerge --info <add here the name of pkg reported by qfile> too? Thank you.

[rdnetto]

Sure:

$ qfile /lib64/libtinfo.so.6
sys-libs/ncurses (/lib64/libtinfo.so.6)

$ emerge --info sys-libs/ncurses

sys-libs/ncurses-6.0-r1::gentoo was built with the following:
USE="cxx gpm static-libs tinfo unicode -ada -debug -doc -minimal -profile -test -threads -trace" ABI_X86="32 64 -x32"
CFLAGS="-O2 -march=x86-64 -pipe"
CXXFLAGS="-O2 -march=x86-64 -pipe"

[Dr-Terrible]

Thank you, I'm now able to reproduce the issue; it's due to the USE tinfo of sys-libs/ncurses.

As a temporarily solution you could disable that USE flag for sys-libs/ncurses only, if you don't have other packages explicitly depending on it (tinfo is a relic of a very old ncurses API/ABI not supported any more). Meanwhile, I'll work out a fix with upstream.

[rdnetto]

Awesome, thanks a bunch! :)

[bpinto]

This would be an awesome package to have on gentoo's main overlay. :)
