Bernhard you are right i should send the code...and make a debug...so I did
this...
I compile a hello world:
#include <stdio.h>
int main(int argc, char **argv) {
printf("\nhello world\n");
}
with this command:
/usr/src/openwrt/fon/openwrt/build_dir/mipsel/OpenWrt-SDK-fonera2n-for-Linux-x86_64/staging_dir/toolchain-mipsel_gcc4.1.2/bin/mipsel-linux-uclibc-gcc-4.1.2
/home/chechu/Documentos/hello.c -o hello
and it works. But when I compile the same program with the sqlite librarie
it hangs. I use this command:
/usr/src/openwrt/fon/openwrt/build_dir/mipsel/OpenWrt-SDK-fonera2n-for-Linux-x86_64/staging_dir/toolchain-mipsel_gcc4.1.2/bin/mipsel-linux-uclibc-gcc-4.1.2
-L staging_dir/mipsel/usr/lib/ -lsqlite3 hello.c -o hello
thanks
