 Posted: Sat Jul 12, 2003 4:46 pm Post subject: ebuild and ${D} |
 |
|
I'm trying to make my first ebuild, and I have basically modified an old one to support a new(and renamed) version of a program.
My ebuild works, if it is installed into root directory. In the end there is however a line that I imagine would break things if someone tried to install this elsewhere. If I change the line(see comment below), the ebuild program tries to link a file in the temporary sandbox dir, and not the final destdir.

} |
My question: how can I resolve this to work in every case, or is it good as it is? |

Is the problem that your link will get erased if the /var/tmp/portage/cdemu* gets cleaned, right?
If so, how about this:

Thanks for the help, and the nicely cleaned SRC_URI 
| Quote: | | Is the problem that your link will get erased if the /var/tmp/portage/cdemu* gets cleaned, right? |
Yes.
However, I propably wasn't specific enough.
| Code: |
into /opt/cdemu/
dobin cdemu
|
If I understand right this will copy the executable(cdemu) to /opt/cdemu/bin. What I wanted to do was get cdemu and libcdemu.py(who need to be in the same directory to work AFAIK) to some directory(/opt/cdemu/) and only link the executable(cdemu) to a directory in the PATH(/usr/bin/).
Of course it would be optimal if someone could figure out how to separate the cdemu and libcdemu.py into two separate directories. |

Is there a reason you're putting it in /opt? The reason I ask is because Gentoo only wants binary-only packages there.
If its just going to be a personal ebuild thats fine, but if you're submitting it to Gentoo I think it might make sense to put libcdemu.py in /usr/lib/python-n.n.n/site-packages/ and cdemu in /usr/bin
Would that work? That way cdemu would find libcdemu, no symlinks needed. |

No. I wasn't aware of the gentoo policy on /opt.

Works!
But then, how can I determine the python-n.n.n directory on a specific users machine?
This one is most likely going to be just a private ebuild, but I want to do it well, so maybe one day I can make submittable ones  |

There may be a better way, but you could use something like:
| Code: | | PY_PRE=`python -c 'import sys;print sys.path[1]'` |
This would give:
/usr/lib/python-2.2 |
