Compile warnings (Suse 10, cpp 4.0.2, *1.2.1, chan_cap_cm 0.6.1)

[loek]

L.S.

Pleas forgive me for asking this question in English, in highschool I allways had a 3 for German (in Holland the scale goes from 1 to 10 with a 10 for perfect...)
But please feel free to answer in (Hoch)Deutsch.

After compiling with this shipload of warnings chan_capi.so is created, using it withing asterisk will give the error "no capi found" as mentioned in earlier postings. I wonder if these two are related? Anyway, i like to know where these warnings come from.
BTW: compiling the Junghanns version gives the same warnings..

TIA,
Loek

I had the same problem once. I tried to update to a CVS-Version after *1.2.1 had been released. Please try the CVS-Version of chan_capi (or 0.6.2). Pver here it now works fine.

This is not related. The warnings come from a buggy compiler I think.
Do you have CAPI installed? Which modules? Which card? Firmware loaded (if necessary)?

BTW: chan_capi-cm CVS HEAD already contains changes for development. The latest version is chan_capi-cm-0.6.2 and fixes will be in CVS branch V0_6

This is just an information.
I have the same warning messages but everything is working fine.
I use:
gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.0.2/configure --prefix=/usr --libexecdir=/usr/lib --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++,objc
Thread model: posix
gcc version 4.0.2

Problem solved: buggy usb connection!

Hi,

You sometimes have those things that one time it works and the next time it doesn't. This time it turned out that the USB cable to the Fritzcard-USB seemed to have a bad contact.
So I checked lsmod, capiinfo etc and it was looking good, and a moment later I checked in *-console and no capi was found. Then you start changing all kind of variables in which process you break all kind of dependencies, and get further from home...

Those compiler warnings indeed have no impact. It is plain vanilla Suse10, so I don't dare to call it a buggy compiler.

If one needs my help on a setup with Suse10/Fritzcard-USB/Asterisk the he/she can call me at +31152568536. It works now

Thanks for all the info,
Loek

Okay, it's not really a buggy compiler, but I think warning about a difference in signedness of pointer types of gcc 4 is not necessary. There has been another compiler used by another SuSE version which is known for a buggy warning.

Anyway, I will clean up the code to remove the warnings (some already done in CVS).
