have you try to put qtopia-core-opensource-src-4.1.4 at /tmp
then tar xvfz qtopia-core-opensource-src-4.1.4
because when my friend try to extract not at /tmp directory he got error.

i am success to configure for embedded arm
# ./configure -embedded arm -little-endian

but i am still stuck at gmake step
