Compiling from source

Compiling from source on Arch system, getting stuck on the following....any help greatly appreciated

checking for tcl... /usr/lib/tclConfig.sh found
checking for tk... /usr/lib/tkConfig.sh found
checking for BWidget using /usr/bin/tclsh8.6... found
checking for BLT using tclsh8.5... not found
checking for img::png using /usr/bin/tclsh8.6... configure: error: not found

new to linux as well, I am thinking there will be a long list of dependencies to be met on arch.....

Excuse my ignorance but is that not for Debian/ubuntu?

No love for Arch?

Not really, if you are new to Linux and want to use Linuxcnc, is there some reason that you want to use Arch? Debian would be a saner choice.

For that matter where did you get the rtai kernel, or are you planning to run on a rt-preempt one?

Your problem is similar to those I have had in the past and revolves around tk / tcl version numbers
You appear to need both 8.5 and 8.6

checking for BWidget using /usr/bin/tclsh8.6... found
checking for BLT using tclsh8.5... not found

Trouble is I have no idea how Arch packages it or which version is default.
Linuxcnc builds on libraries available for Debian (and Ubuntu since that is just repackaged debian)
This may not be the end of your problems.

I do know that I have had to manually remove the config scripts for tk / tcl before now, because if one version was installed and that version is changed, the config script
still refers to the original version and causes all sorts of grief.

Debian being a saner choice.....agreed, but I like the challenge, from time to time. Hardware will be Mesa ethernet card, and from what I am gathering sounds like I will need the preempt kernel, thanks for the input.
