Thanks, but this fix is not correct.

Your change patches a correctly generated Makefile.in, which means that your changes will be overwritten next time someone runs automake, and it's not something that could be accepted upstream.

The real bug here is that the output of "pkg-config --libs libdaemon" is assigned to btnx_LDFLAGS in src/Makefile.am. This should be btnx_LDADD instead, and then the linker flags will be ordered correctly in src/Makefile.in

[Dave Walker (davewalker)]

As discussed with Tarun, as the Natty toolchain has reverted the "ld --as-needed" option - this package no longer FTBFS. However, when the next development cycle opens - this will be an issue. The patch has been submitted to Debian, which will hopefully be applied - and we can sync next cycle.

unsubscribing ~ubuntu-sponsors.

Thanks for your work Tarun!

Dave: *Has* This patch been submitted to Debian? I don't see it in the BTS...

Unfortunatly this patch isn't enough for it to build. It's now running into unused-but-set:

x86_64-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I.. -Wall -Werror -W -Wunused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual -Wswitch -Wcast-align -Wchar-subscripts -Winline -Wnested-externs -Wredundant-decls `pkg-config --cflags libdaemon` -Wall -g -O2 -MT uinput.o -MD -MP -MF .deps/uinput.Tpo -c -o uinput.o uinput.c
uinput.c: In function 'uinput_init':
