I wrote in qtopia_env
#/bin/bash!
echo hello
export QTDIR=$PWD/qt
export QPEDIR=$PWD/qtopia
then
$chmod a+x qtopia_env
but when i
$./qtopia_env
only echo hello works, i do not know why
but
when i change qtopia_env into
echo hello
export QTDIR=$PWD/qt
then
$. qtopia_env(the blank between . and qt is necessary)
all things works
strange!
