Probably easiest to pass $(TCC) to the shell script as an argument I
guess. It needs -B and -I flags to work correctly from uninstalled paths
and the Makefile sets that up correctly.
Does that mean I should use ${TCC} without quotes in the shell script?
No, it's currently not exported from make, so not available in the
environment. What I meant is something like this: extend the script to
take an optional compiler-with-arguments argument, so that it can be
called like:
% ./the-test-script.sh -c "../tcc -B.. -I.. -whatever-else"
and then use it with that argument in the makefile like so:
snip
mytarget: the-test-script.sh
./the-test-script.sh -c "$(TCC)"
snap
Do I need $(TCCFLAGS), too?
The Makevariable $(TCC) should contain everything that's needed.
Still, even the above might be overdesigning it a bit :)
(I see you also access the tcc-tok file directly, so that might further
complicate things from the tests/ Makefile, so don't bother if that gets
you into the rabbit hole too far)
Ciao,
Michael.
