Hi all, I had download the PJProject1.0.1 version tar ball and install it. However, after I ./configure make dep make sudo make install The whole process is run smooth. However, my application seem like cannot find all the header file sucha s pjlib-util... Then When I look in the folder /usr/local/include , I found that all the headers' permission of access is set to "none". So how can I solve this? My OS is Ubuntu 7.10.
