It's not simple, but it's not complex neither:
First install some packages:
sudo aptitude install build-essential autopoint subversion gdb valgrind
I don't think some are missing, but it's not easy to test...
svn co https://foundry.supelec.fr/svn/luatex/trunk
./build.sh --debug --make
Here it might output errors, if it does it means you should install more
packages, please tell me the errors if there are some.
sudo cp /usr/bin/luatex /usr/bin/luatex-old
sudo cp build/texk/web2c/luatex /usr/bin/luatex
fmtutil --byengine luatex
then go in the directory where luaotfload-tool.lua is, run
to know it.
valgrind -v --leak-check=full texlua luaotfload-tool.lua 2>report.log
And see how it goes... It should create a report.log file with things
you can paste us... If it's just never ending, then it's a dead end, and
I'm not sure I can teach you C debugging with gdb in this email... If
it's a dead end, I could try directly on your machine if you have a ssh
access (meaning a public IP address) or teamviewer (works fine for Linux).
Please tell me how it goes!
