Unfortunately, we want to support old versions > of the autotools, so i will have to check that the m4 macro are not too > recent. Most of the m4sugar macros I referred to are quite old. The nice thing about git development is that it is easy to find when something was introduced. For example, m4_toupper was only mentioned in two commit messages: $ git log --pretty=oneline --abbrev-commit --grep=m4_toupper lib/m4sugar/m4sugar.m4 | cat 987a333... Another round of regex avoidance. b60b89e... * m4sugar.m4: (m4_tolower, m4_toupper): New macros. * acgeneral.m4 (AC_PREFIX_PROGRAM): Use m4_toupper(). * aclang.m4 (AC_F77_FUNC): Use m4_toupper()/m4_tolower(). Then you can determine which versions those correspond to: $ git describe --tags b60b89e post-exp-merge-1999-10-31-794-gb60b89e $ git describe --tags --contains b60b89e autoconf-2.50~531 So m4_toupper has been around 531 commits before autoconf 2.50. > > For me, ifelse([$2], [no], [part1], [part2]) executes part1 if $2 is the > same than the string "no", and executes part2 otherwise.

Could you post a snippet where you are actually invoking ECORE_CHECK_MODULE, to make sure there aren't any obvious typos in how you called it? > and what to do with m4_pushdef if i want to transform - to _. For example, I use this: > > pushdef([UP], translit([$1], [-a-z], [_A-Z]))dnl > pushdef([DOWN], translit([$1], [-A-Z], [_a-z]))dnl [m4_]translit expands its result, so the safest approach is to double-quote the first argument in preparation for the later expansion. I would write this as: m4_pushdef([UP], m4_translit([[$1]], [-a-z], [_A-Z]))dnl - -- Don't work too hard, make some time for fun as well!
