Hello, I am trying to install the newest monetdb system with the single bootstrap/configure on my Mac. This does not work as good as it used to be. First when I do ./bootstrap I get the message that the libtoolize cannot be found. This is not installed on Mac OS, the default here is glibtoolize (version = 2.2.4). When using a package managers like fink libtoolize may be already installed in /sw because other packages need it. My solution was to temporary change the bootstrap file. The next problem is that it cannot find the libiconv package. I have libiconv installed in the monetdb prefix but i get the message: configure.ac:2255: error: possibly undefined macro: AM_ICONV When I remove this macro from bootstrap I get the message: configure.ac:152: error: possibly undefined macro: AC_MSG_ERROR This is a hard one because this is a standard macro, What could be wrong here?
