I recently started using Window Maker for my window manager and wanted to begin adding dockapps. The first one I choose to install is Temperature.app-1.4

Unfortunately, I got errors when attempting to build.

I'm afraid I'm not sure what these errors are, or how to go about correcting the situation(s) causing them. Has anyone else shared a similar experience with this particular dockapp, or has my inexperience with Linux caught me again?

Any help would be greatly appreciated. Thanks.

first thing is it appears you don't have the directory
/usr/include/X11
with the X headers in there
install the x developement package for your distribution

foo_bar_foo,

Thanks for the reply. I'll install the developer package when I get home tonight and give it another try.

Installed the development package for X and confirmed that headers are present in the /usr/include/X11 folder. Error warnings still show up when make command is issued as listed.

I was able to install the build and launch the dockapp successfully. I would, however, like to better understand, if not eliminate the warning messages from the process.

Thanks again for any and all help.
