Hi all,
i wold like to try something like this
http://wiki.pinguino.cc/index.php/Interfacing_with_Lua
but having some truble crosscompilig lualibusb...

I can compile lualibusb on my host machine (ubuntu 10.04)

i tried to crosscompile lualibusb following this tutorial:
http://wiki.openwrt.org/doc/devel/crosscompile

but while compilig i have this error:
mipsel-openwrt-linux-uclibc-ld: cannot find -lusb

i think there's some problem linking lusb that i guess stay for libusb (am i wrong???)

here all the message from the compiler:

pippo@clodoveo:~/lualibusb$ make CC=mipsel-openwrt-linux-uclibc-gcc LD=mipsel-openwrt-linux-uclibc-ld
mipsel-openwrt-linux-uclibc-gcc -Wall -D_GNU_SOURCE -I/usr/include/libusb-1.0/ -I/usr/include/lua5.1 -fPIC -o lualibusb lualibusb.o -c -fPIC -fno-stack-protector
mipsel-openwrt-linux-uclibc-gcc: warning: lualibusb.o: linker input file unused because linking not done
mipsel-openwrt-linux-uclibc-ld -shared -soname libluausb.so.1 -o lualibusb.so -lusb lualibusb.o
mipsel-openwrt-linux-uclibc-ld: cannot find -lusb
make: *** [so] Error 1

Can sombody help me??
Tnx

Finally i got it !
libusb.so was not in the righr place.. it had to be inside
<build root dir>staging_dir/ toolchain-mipsel_r2_gcc-4.6-linaro_uClibc-0.9.33.2/lib/

but after package/libusb/compile it was inside <build root dir>staging_dir/target-mipsel_r2_uClibc-0.9.33.2/lib/

coping libusb.so in the right place solved the issue.

Just to let you know ... cheers!
