OpenCPN on Gentoo Linux

[Muhlemmer]

Hi all,

Ebuild for gentoo
For all that like to know: there is a ebuild available in the sunrise overlay. If you are not familiar with Gentoo overlays, you need to do something like this

USE="cvs git subversion" emerge layman
layman -a sunrise

add the following line to your /etc/make.conf:
source /var/lib/layman/make.conf

finaly: emerge -av sci-geosiences/opencpn
Optional: if you want to use any GPS device connected to your box: set USE=gpsd.

Current version in the overlay is 2.1.624 and is tested to compile on my x86_64 system. In a few hours 2.3.1, which is now pending on review by gentoo-sunrise Devs.

Gentoo bug report for feature request of this ebuild: Bug 334283 – New Package: sci-geosciences/opencpn

Maybe above instructions can be included in the installation docs of openCPN?.

Not all options in CMakeLists.txt work correctly
Basicly, the only option we can disable is gpsd in the latest stable, hence the USE flag. Enable of wifi does not work in stable, but it seems to work in GIT/latest beta. Wifi USE flag will be added in ebuild for newer version. For now I'm experimenting with it, before I will commit it to sunrise.

Disabling of s57 and garminhost is not possible. So no USE flags for now.
See bug report: FS#437 : Not all options in CMakeLists.txt work correctly

Why would I like to play with those option.
1. Well, first of all they are noted to be optional, so it should be working like that.
2. That's the point of compiling yourself (and thus Gentoo). Include only (or kick out) anything you do(n't) need, keeping things compact and fast as possible.

Feature requests
I would like to see NMEA interface to be optional. There are plenty users out there that do not use NMEA. (Eg, installed to laptop with only a GPS device, for which we can use GPSD)

Split up languages to be optional to be compiled in.
