is related toDAHLIN-00261 Not enough info in README about successfully building OSLEC echo canceller
Environment:Attachments:( 0) enable_oslec.patch
( 1) oslec_auto.diff
Description:Current way isn't so simple... You have to manually build echo.ko


****** ADDITIONAL INFORMATION ******

To build dahdi & oslec, you have 3 ways:

1. make MODULES_EXTRA="dahdi_echocan_oslec" SUBDIRS_EXTRA=../staging/echo CONFIG_ECHO=m

2. enable oslec in drivers/dahdi/Kbuild
enable echo.ko {
 in /staging/echo/Makefile
 or in kernel's .config
 or "make CONFIG_ECHO=m AND make install CONFIG_ECHO=m"
}
3. with patch (see the attachment)
This will build dahdi_echocan_oslec.ko and echo.ko as simple as possible.
You should simple comment or uncomment 2 lines.

And this assumes you actually have drivers/staging/echo ?

Hmm.. maybe make it build so if those files are present. Look at drivers/dahdi/xpp/Kbuild for ugly inspiration (the way it checks in a very ugly way if a certain patch was applied - BRISTUFF)

A simpler patch. You'd still need to:

  echo 'obj-m += echo.o' > drivers/staging/echo/Kbuild

I'd rather not commit it just yet and wait for next version.

"next version" is published :-)

>   echo 'obj-m += echo.o' > drivers/staging/echo/Kbuild
Thus, the user will have to:
1. copy files from kernel-source
2. path Kbuild file

with
obj-$(DAHDI_BUILD_ALL) += ../staging/echo/echo.o
included, he will have to do only step #1...

I would be interested in testing this, are there any updates or ideas for 2.3.0 and 2.4.0 of DAHDI?
