Re: [asterisk-users] Problems with Dahdi 2.3.0.1 trying to load OSLEC
Hi Tzafrir, Maybe I did not understand very well your answer, but just in case, doing a 'locate dahdi_echocan*' on the Asterisk box, gives me the following output: ... r...@slackbox:~# locate dahdi_echocan* /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_kb1.ko /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_mg2.ko /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_sec2.ko /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_oslec.ko /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_sec.ko /lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_jpah.ko ... Is there something I should change/add somewhere before/post compiling? The documentation on the OSLEC website does not give deeper details about this. Any idea where else should I looK?

Re: [asterisk-users] Problems with Dahdi 2.3.0.1 trying to load OSLEC
Hello Jose. I've found the same problem on some servers and I solved it renaming (or deleting) the echo.ko driver already present in the binary kernel distribution: In my system is something like: /lib/modules/2.6.27.45-0.1-default/kernel/drivers/staging/echo/echo.ko Hope this helps you.

Re: [asterisk-users] Problems with Dahdi 2.3.0.1 trying to load OSLEC
Hi Signorini, I looked for the 'echo.ko' file and is not present but the file 'dahdi_echocan_oslec' is. At compile time, I see this: ... WARNING: oslec_create [/root/dahdi_linux-SlackBuild/dahdi-linux-2.3.0.1/drivers/dahdi/dahdi_echocan_oslec.ko] undefined! WARNING: oslec_free [/root/dahdi_linux-SlackBuild/dahdi-linux-2.3.0.1/drivers/dahdi/dahdi_echocan_oslec.ko] undefined! WARNING: oslec_update [/root/dahdi_linux-SlackBuild/dahdi-linux-2.3.0.1/drivers/dahdi/dahdi_echocan_oslec.ko] undefined! ... I got sure to follow the instructions of the 'README' file of dahdi-linux, but still get this error. Tzafrir Cohen mentioned something about not having the 'echo' or 'oslec' module. In this case it seems that the problem is that the 'echo' module is not present either in the Kernel (built in) or as a loadable module. What I did not see in the README file was a reference about how to make dahdi compile the 'echo' module. I think it might be necessary to compile it separately. I'll google it around to see what I can find. Marco Signorini wrote: Hello Jose.
