By default, the source distribution of cppunit is installed under /usr/local. When you run autoreconf -if, you get an error like this:
$ autoreconf -if configure.ac:37: warning: macro `AM_PATH_CPPUNIT' not found in library configure.ac:37: warning: macro `AM_PATH_CPPUNIT' not found in library configure.ac:37: error: possibly undefined macro: AM_PATH_CPPUNIT If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/local/bin/autoconf failed with exit status: 1
This is because cppunit.m4 is installed under /usr/local/share/aclocal, but aclocal only looks at /usr/share/aclocal-$VERSION and /usr/share/aclocal assuming it was configured with --prefix=/usr. There are 3 ways to specify additional paths.
1. Set ACLOCAL.
ACLOCAL="aclocal -I /usr/local/share/aclocal" autoreconf -if
2. Set ACLOCAL_PATH.
ACLOCAL_PATH=/usr/local/share/aclocal autoreconf -if
3. Set ACLOCAL_FLAGS.
ACLOCAL_FLAGS="-I /usr/local/share/aclocal" autoreconf -if
Apparently older versions of autoreconf don't respect ACLOCAL_PATH or ACLOCAL_FLAGS, so using ACLOCAL is probably the best way to fix it. I'll update src/c/README to document this.
