Re: FD_ZERO in lirc_client causing impossible constraint in 'asm'

[Jeff S. <jef...@gm...>]

Ok I figured it out :-)

there was a problem with the -I flags that the Makefile in the tools
directory was passing.
I saw -I/usr/include it should have been ${prefix}/include
now I have X errors when I don't even have X

fpu/root//include   -O2 -g -Wall -c `test -f irxevent.c || echo './'`irxevent.c
irxevent.c:88:22: error: X11/Xlib.h: No such file or directory
irxevent.c:89:23: error: X11/Xutil.h: No such file or directory

I'll see if I can't pass a better option to ./configure

here is what I did to setup

export \
CC=/root/gumstix-verdex-buildroot-1370/build_arm_nofpu/staging_dir/bin/arm-linux-gcc

./configure \
--prefix=/root/gumstix-verdex-buildroot-1370/build_arm_nofpu/root/ \
--host=arm \
--with-driver=iguanaIR

I'm thinking I need --with-out-X
What else would I need to cross compile
