[DRBD-user] Compile 8.2.6 against kernel 2.6.26.6

[Adrian Chapela]

Hello!

I have installed this kernel on my test machine and I am trying to 
compile drbd 8.2.6 against this kernel and it fails with next output:

make clean all
rm -rf .tmp_versions
rm -f *.[oas] *.ko .*.cmd .*.d .*.tmp *.mod.c .*.flags .depend .kernel*

Calling toplevel makefile of kernel source tree, which I believe is in
KDIR=/lib/modules/2.6.26.6/build

test -f ../scripts/adjust_drbd_config_h.sh && \
KDIR=/lib/modules/2.6.26.6/build O= /bin/bash 
../scripts/adjust_drbd_config_h.sh
/lib/modules/2.6.26.6/build /usr/src/drbd-8.2.6/drbd
/usr/src/drbd-8.2.6/drbd

Using unmodified drbd_config.h

Have you a solution ?

I found a solution in this web: http://winux.tistory.com/tag/DRBD . I 
have changed the lines in the code and drbd compilation works well.

Thank you!
