Bug 31337 – alsa-driver: compilation stops due to redefinition of PDE with kernel 2.4.23_pre7-gss

• Status: RESOLVED DUPLICATE of bug 29965
• Product: Gentoo Linux

[Description Miroslav Šulc 2003-10-17 00:51:40 UTC]

Compilation ends with error because PDE is defined both in adriver.h
(alsa-driver) and in proc_fs.h (kernel 2.4.23_pre7-gss):

In file included from ../alsa-kernel/core/memalloc.c:27,
                 from memalloc.c:28:
/usr/src/linux/include/linux/proc_fs.h:213: redefinition of `PDE'
/var/tmp/portage/alsa-driver-0.9.2/work/alsa-driver-0.9.2/include/adriver.h:111:
`PDE' previously defined here
make[1]: *** [memalloc.o] Error 1
make[1]: Leaving directory
`/var/tmp/portage/alsa-driver-0.9.2/work/alsa-driver-0.9.2/acore'
make: *** [compile] Error 1

!!! ERROR: media-sound/alsa-driver-0.9.2 failed.
!!! Function src_compile, Line 59, Exitcode 2
!!! Parallel Make Failed


Reproducible: Always
Steps to Reproduce:
1. Install kernel 2.4.23_pre7-gss and create link from /usr/src/linux to this
new kernel
2. emerge -v alsa-driver

Actual Results:  
Compilation for alsa-driver failed

Expected Results:  
Shouldn't fail ;-)

I solved the problem by commenting the PDE definition in adriver.h and
compilation finished successfully.

This bug has been fixed in alsa-driver cvs, so the next release after 0.9.7c
should fix it.
This is the fix being used in the alsa-driver cvs: -
