[uClibc]buildroot can build a uClibc development system

[Erik Andersen]

FYI...  buildroot can now build a uClibc only development system.
Its been a long time in the making, but it now works.  Building
things withing such a standalone system should avoid all of the
painful cross-configuration problems that have caused us such
grief.

So now that I have built a standalone uClibc development
system...  Anybody know how to setup a Debian autobuilder?  :-)


[andersen at dillweed buildroot]$ cp hello.c build/root/tmp/
[andersen at dillweed buildroot]$ sudo chroot build/root/

[root at dillweed /]# cd /tmp/
[root at dillweed bin]# which gcc
/usr/bin/gcc
[root at dillweed bin]# ldd /usr/bin/gcc
        libc.so.0 => /lib/libc.so.0
        /lib/ld-uClibc.so.0 => /lib/ld-uClibc.so.0
[root at dillweed tmp]# gcc -Wall -Os -s hello.c -o hello

[root at dillweed tmp]# ./hello 
hello world
[root at dillweed tmp]# gcc -Wall -Os -s hello.c -o hello -static
[root at dillweed tmp]# ldd ./hello
        not a dynamic executable
[root at dillweed tmp]# ls -l ./hello
-rwxr-xr-x    1 root     root         5276 Nov 14 11:41 ./hello
[root at dillweed tmp]# ./hello 
hello world
