Hi Jason! [building from the CVS snapshot] > In bl I am missing the macro AM_ACLOCAL_INCLUDE You can just edit the configure.in in the subdirectory bl to remove this AM_ACLOCAL_INCLUDE line. I got rid of this a little while back (after the snapshot, unfortunately!) because it is a pain -- sometimes it seems to be AM_ACLOCAL_INCLUDE, sometimes it's AC_ACLOCAL_INCLUDE. Anyways, it isn't really needed, so you get rid of this line and this will hopefully make everything happy. > I am also getting the errors: > configure.in:40: [[error: [[[backquotes and double quotes should not be backslashed in: [[configure: error: [Couldn't find the python config makefile. Maybe you are > missing the development portion of the python installation]]]]]]] > ]configure.in:40: /usr/bin/m4: Non-numeric argument to built-in `m4exit' Hmmm, I've never really seen this, but it seems like the problem might be indicated in this last message. I think many linux systems come with python pre-installed, but do not include the headers and things, which you'll need to compile piper since it builds C++ extensions to python. You can check for the headers in some place like /usr/local/include/python2.0/ or /usr/include/python1.5 or something, depending on your version and the install prefix. If you don't have them I believe there is a python-dev rpm for linux systems that you'll need to install. If you do have them, then I'm kind of stumped why configure is complaining so much... Let me know if this helps. Brad
