Ah - I'd say there was a near zero chance to even guess that.

Could you please try to add notes about this in gdb's configure.ac (a 
note on --enable-gdbtk about both the project Insight and about "only 
for using GDB as Insight submodule" - would help a lot) and possibly on 
GDBs mode options docs (something along "-w  start GDB in GUI mode 
(Insight)") and help output, too?

How to get the files without git (newest insight + GDB [12.1] I've 
already on the harddisk)? Is the build info [1] still up-to-date that I 
need to build it with a specific tcl/tk version?


https://sourceware.org/insight/downloads.php seems to be quite outdated, 
too (ftp links don't work here, instead of git web frontend it points to 
cvs)

Thanks, just checking for the necessary source files (before even 
checking tcl/tk), then abort looks most reasonable to me.

I guess this is all rooted in the mentioned TODO 2

 > Get Insight integrated and accepted into the GDB mainline.

Question on that: Is it likely that this will happen someday?

Thanks again for taking the time to answer!
