Dear PPL developers,
The PPL library requires a recent version of GNU m4, but this isn't documented anywhere as far as I can tell, certainly not here: http://bugseng.com/products/ppl/requirements http://bugseng.com/products/ppl/portability
Dear Jeroen,
thanks for the report. You are right, of course, about the web page on PPL requirements: we will amend it. The need for a recent version of M4 is documented in README.configure, though.
In particular, it fails to configure on OS X 10.4:
$ ./configure checking build system type... powerpc-apple-darwin8.11.0 checking host system type... powerpc-apple-darwin8.11.0 [...] checking for GNU M4 that supports accurate traces... configure: error: no acceptable m4 could be found in $PATH. GNU M4 1.4.5 or later is required; 1.4.11 is recommended
$ m4 --version GNU m4 1.4.2
Do the m4-generated files depend on the architecture? If not, you could simply ship them with PPL and not require m4.
They depend on the configure options used for building the PPL from its sources. Kind regards,
Roberto
