Hi: When I run the java under linux system, using the javac , java command, the error message resulted: Segment fault, SIGSEGV 11* Segmentation violation ...... So, I need update the libXt.so.6.0, I followed the URL listed on the installation guide: http: // www.blackdown.org/java-linux/downloads/libXt.tar.gz But, I can not enter the URL, web page, Is this address changed? Or How can I do the updating in another way. Thank you Michael
