Dear Richard, with cln 1.1.4, `make install' ends up as follows ... make[1]: Leaving directory `/usr/local/distrib/objdir/doc' /usr/bin/install -c cln-config /usr/local/bin/cln-config /usr/bin/install -c -m 644 cln-config.1 /usr/local/share/man/man1/cln-config.1 /usr/bin/install -c -m 644 cln.m4 /usr/local/share/aclocal/cln.m4 /usr/bin/install: cannot stat `cln.m4': No such file or directory make: *** [install] Error 1 Notice that I am building the library in a separate directory. The problem seems due to the fact that cln.m4 is looked for in the build directory instead of the source directory. The easy workaround is in fact to copy cln.m4 from the source directory to the build directory just before issuing `make install'.
