Hi,
I noticed the following in release notes for flex 2.6.{3,4}, which may
be relevant to this bug.
2.6.3:
"""
A new configure option --disable-bootstrap changes the behavior of
the build system when building flex. The default
"--enable-bootstrap" behavior is to build flex, then to use that
flex to build flex again. With --disable-bootstrap, the scanner is
simply built by sedding the scanner source. This is friendlier to
cross compilation.
The compatibility functions in lib/ are no longer built as a
library. Instead, they are built as $(LIBOBJ) objects. This is
simpler and friendlier to cross compilation.
It is now possible to build flex without building the accompanying
libfl. This is friendlier to cross compilation. See the
--disable-libfl option to configure. Resolves #99.
[...]
the distributed man page is only rebuilt when the relevant source
files change or when the binary doesn't exist. In particular, this
is friendlier to cross compilation. Resolves #108
""""
2.6.4:
"""
Flex can be cross compiled.
"""
I.e. this looks like it is now solvable by upgrading to a newer version
of flex (and passing the proper flags to configure during cross building).
Thanks,
~Niels
