I'm getting segfaults after building with the version of QT; 4.7.3 fwbuilder: segfault at 8 ip 00007f770307686b sp 00007fffc7ea4430 error 4 in libQtGui.so.4.7.2 I've met the requirements, using #2 below. Hope that was correct. 1. Qt SDK: Complete Development Environment : Qt SDK for Linux/X11 64-bit** (23 MB) 2. Qt: Framework Only : Qt libraries 4.7.3 for Linux/X11(204 MB) Also, I'm wondering… is there a method to double check if Firewall Builder is generating iptables correctly? For example, I've installed your binary: fwbuilder_4.2.0.3530-ubuntu-natty-1_amd64.deb on "Debian Testing"… It hasn't crashed yet, and the Firewall generated seems to be logical and OK. I really don't have a choice if I want the latest Firewall Builder (I do) on Debian Testing… I don't know which is a better choice… a.) Use the Ubuntu version b.) Use the 'alien' program to convert a .rpm version May I ask for some feedback please. If you would like to refer to this comment somewhere else in this project, copy and paste the following link: Mike Horn - 2011-05-04 Also, I'm wondering… is there a method to double check if Firewall Builder is generating iptables correctly? For example, I've installed your binary: fwbuilder_4.2.0.3530-ubuntu-natty-1_amd64.deb on "Debian Testing"… It hasn't crashed yet, and the Firewall generated seems to be logical and OK. There are a few ways to verify the iptables configuration. 1) You can use the "Inspect Generated File" option that is shown after the Compile is completed that will open the script file (iptables commands are towards the end). You can also open the generated script (.fw) in a text editor to review. 2) You can use the "Compile Rule" command to see what fwbuilder will generate for a specific rule. Select the rule and either press "X" key on your keyboard or right-click on the rule and select Compile Rule option. There is a short video tutorial about this on our website here http://www.fwbuilder.org/4.0/videos2.html About the segfault, we'll need
