hi, building drbd-8.2 from git for the long maintained 2.6.27 kernel series results in the following error: > /usr/bin/make -C drbd KERNEL_SOURCES=/root/src/linux-2.6.27.13 MODVERSIONS=detect \ > KERNEL=linux-2.6.27.13 KDIR=/root/src/linux-2.6.27.13 2>&1|less > make: Entering directory `/usr/src/modules/drbd/drbd' > > Calling toplevel makefile of kernel source tree, which I believe is in > KDIR=/root/src/linux-2.6.27.13 > > test -f ../scripts/adjust_drbd_config_h.sh && \ > KDIR=/root/src/linux-2.6.27.13 O= /bin/bash ../scripts/adjust_drbd_config_h.sh > make: [kbuild] Error 1 (ignored) > /usr/bin/make -C /root/src/linux-2.6.27.13 SUBDIRS=/usr/src/modules/drbd/drbd modules > make[1]: Entering directory `/root/src/linux-2.6.27.13' > CC [M] /usr/src/modules/drbd/drbd/drbd_buildtag.o > CC [M] /usr/src/modules/drbd/drbd/drbd_main.o > In file included from /usr/src/modules/drbd/drbd/drbd_main.c:52: > include/linux/swab.h:47: error: redefinition of ‘___swab16’ > include/linux/byteorder/swab.h:65: error: previous definition of ‘___swab16’ was here > include/linux/swab.h:58: error: redefinition of ‘___swab32’ > include/linux/byteorder/swab.h:69: error: previous definition of ‘___swab32’ was here > include/linux/swab.h:69: error: redefinition of ‘___swab64’ > include/linux/byteorder/swab.h:75: error: previous definition of ‘___swab64’ was here > In file included from /usr/src/modules/drbd/drbd/drbd_main.c:52: > include/linux/swab.h:109:1: warning: "__swab16" redefined > In file included from include/linux/byteorder/little_endian.h:12, > from include/asm/byteorder.h:79, > from include/asm-generic/bitops/le.h:5, > from include/asm-generic/bitops/ext2-non-atomic.h:4, > from include/asm/bitops.h:451, > from include/linux/bitops.h:17, > from include/linux/kernel.h:15, > from include/linux/cache.h:4, > from include/asm/pda.h:7, > from include/asm/current.h:19, > from include/asm/processor.h:15, > from include/linux/prefetch.h:14, > from include/linux/list.h:6, > from include/linux/module.h:9, > from /usr/src/modules/drbd/drbd/drbd_main.c:29: ... the reason for this is a commented define in drbd_config.h since [1][2] > //#define HAVE_LINUX_BYTEORDER_SWABB_H which *should* get fixed by a call to ../scripts/adjust_drbd_config_h.sh which was commented out of ./debian/rules:108 way back in 2006 (or so). for me, living on debian, simply uncommenting this line resolved the module-assistant build issue. maybe there is a more elegant way to handle this (e.g. passing some CFLAGS). i just spend some time on searching for the cause - so hopefully i can save the time of others.. cheers, raoul [1] http://git.drbd.org/?p=drbd-8.2.git;a=commit;h=a241f2bdf8dc903d5afcb656dd265bea82afec61 [2] http://git.drbd.org/?p=drbd-8.2.git;a=blobdiff;f=drbd/linux/drbd_config.h;h=4cd5733ba48a2a646e6fca3e3d1d8f1a02e5a98a;hp=80c636e62403e9ce810d7c55ef7c354c87756114;hb=a241f2bdf8dc903d5afcb656dd265bea82afec61;hpb=859d57e2d2791be9e6e027f6812cdb4ecc517e40 -- ____________________________________________________________________ DI (FH) Raoul Bhatia M.Sc. email. r.bhatia at ipax.at Technischer Leiter IPAX - Aloy Bhatia Hava OEG web. http://www.ipax.at Barawitzkagasse 10/2/2/11 email. office at ipax.at 1190 Wien tel. +43 1 3670030 FN 277995t HG Wien fax. +43 1 3670030 15 ____________________________________________________________________
