General installation

How do I install the package that I downloaded?

If you downloaded the .tgz version, unpack it on the command line with "tar -xzf file_name.tgz" and then follow the simple instructions in the top level README file. Each archive within the package contains a lib directory with libraries that need to be installed in order to run the program. The README file explains the best place to put these libraries.

If you downloaded the .rpm version, unpack it on the command line with "tar -xzf file_name.tgz", log in as root, and either use an RPM Manager program or install the package(s) with "rpm -i --force file_name.rpm". If the installation fails because it cannot find the appropriate version of libstdc++, run "rpm -i --force --nodeps *.rpm".

Can I install the RPM on Linux systems other than RedHat?

Yes. Caldera, Corel, Mandrake, and SuSE all support it directly. If the RPM does not work on your system, please try the tar package.

For Debian, do the following:

1. Download the Linux-Intel binary.
2. Run "alien" on the .rpm file.
3. Run "dpkg -i --force-overwrite" on the resulting .deb file.

I just downloaded and installed the rpm. Where is the binary?

Run "rpm -qlp" on the .rpm file to list the files that it installed.

The binary that I downloaded doesn't work on my system. Does this mean that I have to obtain the source?

General configuration

When I type in an input area in a dialog window, buttons and checkboxes get activated. How do I avoid this?

We are not sure what causes this. We think that it may be the result of strange bugs in particular window managers. What is happening is that the program is somehow being told that the Meta key is pressed. Apparently, if you hold down the Meta key, this toggles the setting, i.e., turning the Meta key off, so that you can type normal characters. The best solution is to switch to a different window manager.

Where is the Meta key?

On Linux-Intel, it is usually labeled Alt. The default on Debian Linux running on a UK keyboard apparently maps Meta to the Windows Logo key. On other UNIX machines, Meta is sometimes labelled with a diamond. If you can't find it by trying the various strangely labelled keys on your keyboard, please ask your system administrator.

Why don't the Meta menu shortcuts work?

Add the following command to your ~/.xinitrc file:

xmodmap -e "keysym Alt_L = Meta_L Alt_L"

If you are using TightVNC, run vncserver with the -compatiblekbd option.

Why doesn't Meta-click work?

Your window manager is probably grabbing the mouse click so the program never gets it. Most window managers provide a configuration file that you can change so the mouse click isn't grabbed. If your window manager doesn't allow this, ask the developers to add this feature!

If you are using Enlightenment, holding down both Meta and Control will get around this problem.

With KDE, go to their control panel LookNFeel/Window Behavior/Actions and set "Modifier Key + Left button" to "nothing".

Why does the backspace key delete the character to the right instead of the character to the left?

This is a problem with your X server configuration. Somehow, your backspace key is generating Delete instead of BackSpace. On UNIX, the problem can be solved by adding

xmodmap -e "keycode 22 = BackSpace"

to your ~/.xinitrc file. If you are using an X server for Microsoft Windows®, please consult the appropriate documentation.

When I iconify (minimize) a window on the Gnome desktop, the window doesn't redraw when I deiconify it. How do I fix this?

Switch from using the Sawfish window manager to the Enlightenment window manager. This is a preference somewhere in the Gnome configuration editor.

When I used XVision, the Meta key doesn't work. How do I fix this?

Make a copy of the appropriate XVision key mapping file in <XVision installation directory>\System\keymap and then modify it to change the description on the first line (DESC) and to map the desired Windows virtual key code (usually VK_MENU) to the X keycode "0xffe7 (Meta_L)". Save this file and then run <XVision installation directory>\Xkg.exe. From this application's File menu, open the key mapping file you just created. This compiles your .txt file into an .xkg file. Choose "Save" from the File menu and quit the application. Now open the XVision properties dialog and choose the Devices tab. Your new keymap should appear in the Keyboard Map drop down list, based on the change you made to the first line of the .txt file. Select it and then let XVision restart.

Thanks to Ian Wakeling for figuring this out.

JX Development Suite installation

I tried compiling the JX tutorials, but it failed. What do I do?

You must first compile JX itself.

I tried compiling the JX source, but it failed. What do I do?

License issues

What restrictions are imposed on the code that I develop with the JX Application Framework?

You are allowed to distribute software that is statically linked with the JX libraries. You are not allowed to distribute the source code.

Software

There is a separate FAQ for each of our programs:

Miscellaneous

I don't use Linux. Can I still use your software?

Yes, we are willing to work with you to get our code to compile on any UNIX system. We are also interested in porting our software to MacOS X, by running inside their X server. Please contact us directly.

Is there a Windows® version?
