Bug Description

Binary package hint: lcdproc

I've installed g15tools and I tried to use the g15 output in LCDd : Could not open driver module /usr/lib/lcdproc/g15.so: /usr/lib/lcdproc/g15.so: cannot open shared object file: No such file or directory

How to reproduce it :
install g15 tools, by compiling it. Namely and in this order
- libg15
- lig15render
- g15daemon
- g15composer
These are not packaged yet

modify LCDd.conf to use g15 driver (supported since lcdproc 5.2)
# The following drivers are supported:
# bayrad, CFontz, CFontz633, CFontzPacket, curses, CwLnx, ea65,
# EyeboxOne, g15, glcdlib, glk, hd44780, icp_a106, imon, IOWarrior,
# irman, joy, lb216, lcdm001, lcterm, lirc, MD8800, ms6931, mtc_s16209x,
# MtxOrb, NoritakeVFD, picolcd, pyramid, sed1330, sed1520, serialPOS,
# serialVFD, sli, stv5730, svga, t6963, text, tyan, ula200, xosd
Driver=g15

restart LCDd : /etc/init.d/LCDd restart

check syslog :

Confirmed, this is also true in the upcoming Hardy release, even less excuse there as the G15 tools are available as packages from the Hardy repositories.

I think what is happening is that the package maintainer does not have the G15 build dependencies satisfied as lcdproc will just skip any driver libraries it can't build because of missing development packages.

With the missing G15.so file taken from a complete build of lcdproc, everything works as expected.

g15daemon etc are included in the Ubuntu repositories as of Hardy. Does the problem still occur with Hardy or Intrepid? Thanks in advance.

Not sure about Intrepid, but g15.so is still missing from the Hardy 64bit packages (and I believe the 32bit ones as well).

As I mentioned I think the issue is that the maintainer did not have the libg15 dev packages installed when they built lcdproc. This being the case the lcdproc configure script skips creating the g15 driver library.

Just to confirm this still appears to be the case in Intrepid (8.10)

I can't see g15.so in the Debian lcdproc package either, but it's there in libg15-dev. Marking triaged.

This bug could be fixed by build-depending on libg15daemon-client-dev and libg15render-dev.

I experienced the problem too, the solution is to simply add the dependencies libg15daemon-client-dev, libg15render-dev and libg15-dev to the debian control file. Then the driver compiles fine. The attached diff output contains the changes I made.
This is my first contribution, so I hope everything is correct :-)

Here the whole diff file again, now including the changelog entry.

I'm not sure about the version number, I hope it is correct like that.

Uploaded. Thanks for your contribution!

I just had to fix the changelog entry :-) Using dch is recommended to avoid having problem with it ;-)
