Hi folks,
I've found a bizarro error that may in fact relate to
Cygwin/bash. I'm using the latest version (ran setup and refreshed
just yesterday).
In the linux kernel configuration process, there is a rule in
/linux-2.4.x/makefile that looks like this:
dep-files:
scripts/mkdep -- `find .....` > .hdepend
The find command returns a huge list of header files, from which
dependencies are derived.
After some digging I've found that it fails when the length of the
string returned by `find...` exceeds about 32K characters. It doesn't
seem to matter how many file names are returned, just the total length
of the string that contains them all.
This may be a bug in the mkdep utility, but I suspect more that it
might be a limitation in Cygwin or bash. Is there some fundamental
limitation to the length of the argv[] array when launching programs
under Cygwin/bash?
I created a workaround by doing
dep-files:
rm -f .hdepend
find .... | xargs scripts/mkdep -- >> .hdepend
But this means I need to patch over the standard linux build
distribution before doing anything under Cygwin.
Can anyone confirm or deny?! :)
Cheers,
John
