after commit 501cf77d4dabd4393a7de202f16f1b5a3537c479 everything is broken about bsc HOT 5 CLOSED

Before that, the repo contained source for tcl/tk and itcl/itk, which were built and used. After that commit, these sources were removed and it became a requirement that users install tcl/tk and itcl/itk first. The failure you're seeing is because itcl is not found. What OS are you building on? If you're on Debian or Ubuntu, you'll need to install the itcl3-dev and itk3-dev packages (which commit aba212e added to the README file).

installing those does not help

from bsc.

There was a commit (d3f81bf) an hour ago that introduced a new requirement, the split library. If you look at the changes to the README file by that commit, you'll see that you now need this:
apt-get install libghc-split-dev

from bsc.

The untracked src files are because those directories were deleted in later commits that you pulled in, but there were generated files in those directories and they are still around. You can safely delete those directories.

ok,,checking README file now all the time and not just splitdev but mtl libraries pop up there
thank all good for now
