4) What compiler version are you using? I found this possible fix by searching the error message, but of course there's no guarantee you won't get more errors compiling later. Since SCIRun on Arch is unsupported by SCI, you can start by following all the requirements listed on http://www.sci.utah.edu/cibc-software/scirun.html; if there are still problems you'll have to resort to the community.

5) Just download Qt 4 and install wherever you want, then point the build to that qmake rather than /usr/bin version. For instance, there is a package available at https://www.archlinux.org/packages/extra/x86_64/qt4/.

Hi,

I got errors when building SCIRun v4.x on Linux Arch. I tried several 4.x versions, as well as SCIRun linux and source packages, but all returned the same error shown below. The error seems to have do with tcl/tk. 

Also I got errors when building SCIRun v5. It seems that SCIRun requires Qt 4 whereas my computer is using Qt 5.

Any suggestions would be greatly appreciated. Thanks!

Cheers,
Dafang
