[gentoo-dev] another kdemultimedia bug?

[Grant Goodyear]

When emergeing kdemultimedia-2.2.1 the compile failed with 
motif_p.c: In function `motif_pipe_error':
motif_p.c:58: `errno' undeclared (first use in this function)
motif_p.c:58: (Each undeclared identifier is reported only once
motif_p.c:58: for each function it appears in.)
make[3]: *** [motif_p.o] Error 1
make[3]: Leaving directory `/var/tmp/portage/kdemultimedia-2.2.1-r1/work/kdemultimedia-2.2.1/kmidi/TIMIDITY'

I hacked motif_p.c by adding a "#include <sys/errno.h>" line at the
top, and it went merrily along its way until crashing out at the
now-well-known alsa bug (although I had to hack lines 429, 435, 
459, and 469 to get them to work).  Has anybody else seen the first
error?  My USE variables are 

USE="slang readline gpm berkdb gdbm tcpd pam libwww ssl
    lm_sensors lvm pcmcia-cs alsa
    nls mmx mitshm
    esd lcms gif sdl vorbis ogg
    gnome gtk X qt kde motif opengl mozilla
    perl python tcltk objprelink tex"

Thanks,
Grant

This same error was reported by chadh recently, thread "KDE Problems", but 
remains unresolved. I (the primary kde packager) haven't encountered it, so 
there's little I can do.

Suggestion: post diff for your mods that bypassed the problem. Let chadh test 
it and see if it helps, and I can test it to see it doesn't create any 
problems where there aren't any. If everything's OK, we can add the diff to 
portage.

However, it'd be much nicer to find out what's actually causing this. ;-)

The kdemultimedia ebuild has optional fnuctionality for the folloing USE 
flags: alsa, nas, esd, motif, gtk, slang.
I have these on: motif, gtk, slang
You: alsa, esd, motif, gtk, slang

So it might well be due either to alsa or to esd optional functionality.

[gentoo-dev] A cuople of questions

[Jake Bishop]

When I try to emerge anything from  gnome-extra, mc for instance,I get ebuild
gnome-extra/mc-4.5.55 not found ( possibly blocked by package.mask).Also I am
trying to get alsa working.I think the docs on the Web sight are out of date?. I
am using 1.0-rc6-r9 with the 2.4.10 kernel. I have sound compiled into the
kernel.
I have emerged all the Alsa pkges - drivers,utils and libs.Other than that
everything is great with Gentoo.
Thanks

Okay, I have the same problem Grant has.  It is probably related to Alsa.  I 
modified the motif _p source file to include sys/errno.h.  The later errors 
are as follows:

alsa_a.cpp: In function `int set_playback_info(void *, uint32 *, uint32 *, 
const long int *)':
alsa_a.cpp:287: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
alsa_a.cpp:429: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
alsa_a.cpp:435: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
alsa_a.cpp:451: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
alsa_a.cpp:459: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
alsa_a.cpp:469: ANSI C++ forbids implicit conversion from `void *' in 
argument passing
make[3]: *** [alsa_a.o] Error 1

I'm an RPG programmer on the AS400.  I can pursue this further, but I am 
hoping someone else may know what the problem is.

Found the problem.  kdemultimedia compiled on my box and the multimedia 
components work now.  The problem is a known KDE bug -  
http://bugs.kde.org/db/27/27332.html.  After putting in the fix, everything 
compiled well.  The two fixes are:

  Grant's motif_p.c fix - Add #include <sys/errno.h> to the top of motif_p.c

  KDE's fix is to modify line 257 of alsa_a.cpp
  Replace static int set_playback_info (void* handle__, .......  )
  with       static int set_playback_info (snd_pcm_t* handle__, ....... )

I'd give you a diff, but have never done one and figured you would probably 
want to run through this one anyway.

Thanks for a great distribution.

[Dan Armak]

Hi again,

I'll put in the fix, do a test compile, and commit it. Thanks for the pointer.

BTW, the motif_p.c fix is already in cvs.
