I'm attempting to build udhcp and haserl and having
some...complications...that may be beyond me.
When I attempt to make udhcp, I can tell that it's using the host gcc
instead of the target gcc ($CLFS/cross-tools/<target arch>-gcc).

************end of output****************
I looked at the Makefile and noticed that just about everything is
defined--prefix, CC, LD, STRIP--thus not using the environment variables
passed from the shell (right?).
I commented out all of the lines that specify anything already defined
in the environment (CC, LD, STRIP). When I tried to make it again, I get
a metric ton of undefined references to regular functions like socket
and printf.
When I attempt to make haserl, this is the output:
[root /mnt/vj/sources/haserl-0.9.16]# ./configure --prefix=$CLFS/usr
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes

checking for gcc... i486-pc-linux-uclibc-gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
[root /mnt/vj/sources/haserl-0.9.16]#
If I create a dummy.c file with something like "int main(){return 0};"
in it and compile it, it works fine, but obviously I can't run it
because my host environment is different (host is i686 glibc, target is
i486 uclibc).
Relevant lines from config.log:
configure:2357: i486-pc-linux-uclibc-gcc -V >&5
i486-pc-linux-uclibc-gcc: '-V' option must have argument
configure:2360: $? = 1

configure:2481: $? = 127
configure:2490: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
I know that there is probably not anything wrong with my build
environment variables or permissions or the like, because I built
dnsmasq just fine just now.
Ideas?
