hi, it seems neither mingetty nor rungetty is available in T2. Maybe someone can point me to it ? thanks Tobias Gruetzmacher wrote:

Hi I'm sending this to T2 and mms http://forum.mymediasystem.org/ http://forum.mymediasystem.org/ , I hope we can solve the problem together. Below an example for a g++ command causing the problem "cannot find -lz". Note there is always a "-Wl,-nostdlib" and a "-L/usr/local/lib". So I copied manually the libz.a (static lib) to /usr/local/lib. This makes nobody, except ld, really happy, although it worked. Note also: ldd /usr/lib/mms/plugins/lib_output_sdl.so libz.so.1 => /lib/libz.so.1 (0xb7f03000) So it seems ld is happy to find a static lib, but does not use it ? Is the command line wrong or the way g++ interprets it ? Gerd example: g++ -I/usr/local/include -L/usr/local/lib -I/usr/include/ -I. -pthread -pipe -O3 -ffast-math -funroll-loops -fomit-frame-pointer -funit-at-a-time -D_GNU_SOURCE -isystem/TOOLCHAIN/src.mms.mindesk.20081001.142917.825.localhost/mms-1.1.0-rc8/libs -I../ -I../../ -I../../../ -I../../feature/ -I../../input/ -fPIC -shared -Wl,-nostdlib -o lib_output_sdl.so sdlout.o sdlout_pl

Why it failed before I do not know off handeither. /opt/*/lib... are not searched by default, which is why there are the pkg-config files (or the old -config scripts) for packages to obtain the correct pathes on a distribution - which varies between releases, vendors (Fedora, Debian, etc.) and in T2 even between configurations. If the package configure does not include any support you would have to patch it in (or use T2 automatics to inject it), but the configure script might have a --with-imlib option to specify the patch.

Re: .eh_frame error

gx-turbo — 2008-10-02T15:18:36

The main problem is the missing lib(s), probably due to confused search path and/or different lib locations (/lib, /usr/lib ?) on different systems. In Makefile I found only -L/usr/local/lib. How does ld or gcc find libs ? seems it looks in /usr/lib, but not in /lib. To make progress, I copied *.a from /lib to /usr/local/lib /which was empty before). Now all errors disappeared. I really would like to know why this package has this library problems. You may remember there is also the pending imlib2 problem. Should not be that big rocket science to fix it, or ? What is your recommendation how to solve it ? regards Gerd gx-turbo wrote:

hi, there is another problem with all gcc/binutils: /usr/lib/gcc/i486-t2-linux-gnu/4.2.2/../../../../i486-t2-linux-gnu/bin/ld: cannot find -lz I found this also with a native compile on a T2 system, but here without the eh_frame error. libz I found in /lib seems to be a problem with ld search path ?

Re: VIA UniChrome X11 driver

René Rebe — 2008-10-01T17:11:11

Hi, I think the openchrome tree has video output and XVideo acceleration - maybe even mpeg, but I have not checked. I think the mostly only missing area is open source 3d for those chips (but we have not used it for video output, so YMMV). You might have to manually edit the xorg.conf to list the openchrome driver. gx-turbo wrote:

Great!, I have not noticed the openchrome in T2. Will try this one asap. Problems are typically video output, mpeg-acceleration. Any experience on that ? A "good" x.conf file ? Is the installer aware of it ? Gerd René Rebe wrote:

PostgreSQL 8.3 - init script

2008-10-01T07:48:37

Hi All, I am not expert in postgres. However trying to make it work (T2 8.0 trunk, rev 29913) I found that the init script (/etc/init.d/postgresql) refers to the postmaster link which is working for manual start, but since it does not give back the terminal command line it prevents the whole system to finish booting if used as init script. I have found that pg_ctl instead of postmaster works better, but in this case I do not manage to restart the Postgres server. I am sure the answer can be found on the internet, but if there could be anyone in the know how to solve this, it may spare a lot of time for me, and (in the case the T2 SDE init script for postgres can be improved) also for others. (I have already "waste" some time in searching) Thanks in advance! helasz

hi sorry, have to bother you again with my mms ... With the latest trunk it did not build, although some weeks before it did. Now I get a couple errors from .../bin/ld, like: error in .../output.o (.eh_frame); no eh_frame_hdr table will be created A quick look in google let me think this is NOT something like a missing library, but could be a binutils or gcc problem. any idea what can help ?

The cause is that the new pango requires a newer cairo, which I did not yet update as it was an interim development version and as I had the old cairo backend for pango on my system the new gtk+ did not fail.

hi, I did a loop through versions back and forth and then made a new svn trunk. Now I'm back at the original 2.14/1.22/2.18 and now gtk+ 2.14 is built.
