Hello, here is a quick answer to some of your problems: Please use aclocal19, you won't get any reasonable support for the older releases, and the latest libtool probably works best with Automake 1.9. aclocal uses two directories, with the following default locations: /usr/local/share/aclocal-1.9 ... the version specific one, contains macros which are part of the Automake package, as the aclocal script itself. /usr/local/share/aclocal ... a directory for third party macros; each package installs a few *.m4 files. Run the command: grep ^.acdir /usr/local/bin/aclocal19 to find out what is the general aclocal directory for the script. Let's suppose it'll be /usr/local/share/aclocal. (Then /usr/local/share/aclocal-1.9 is the version specific one.) But it seems that some packages, for example libtool, installed their macro files to /usr/local/bin/aclocal, which means that aclocal19 cannot find them. Then use echo /usr/local/bin/aclocal >/usr/local/bin/aclocal19/dirlist to tell aclocal19 about the other directory. > My build commands are as follows: > libtoolize15 --copy --force > aclocal19 > autoconf259 > automake19 This looks fine. Make sure that these programs are using GNU m4 (installed as gm4, probably) and not the BSD m4. If any problem remains, please post another question. The questions 1) and 2) in your mail seem to be libtool problems; if the remaining problems still are about ltmain and such, it might be best to post a new question to libtool@xxxxxxx, they will help you more.
