I am getting some errors building 1.8 on RHEL6. I tried autoreconf as suggested, but it failed for the same reason. Is there a minimum version of m4 required that is newer than that provided by RHEL6?
Thanks aclocal.m4:16: warning: this file was generated for autoconf 2.69. You have another version of autoconf. It may work, but is not guaranteed to. If you have problems, you may need to regenerate the build system entirely. To do so, use the procedure documented by the package, typically 'autoreconf'. configure.ac:40: error: m4_defn: undefined macro: _m4_divert_diversion configure.ac:40: the top level autom4te: /usr/bin/m4 failed with exit status: 1 [bloscel@head openmpi]$ autoreconf configure.ac:40: error: m4_defn: undefined macro: _m4_divert_diversion configure.ac:40: the top level autom4te: /usr/bin/m4 failed with exit status: 1 aclocal: autom4te failed with exit status: 1 autoreconf: aclocal failed with exit status: 1
