Error: cannot find a working diff3 library program

Question

While compiling rcs on AIX I got the following error:

# ./configure
creating cache ./config.cache
checking diff basename... diff
checking for diff... /usr/bin/diff
checking diff success status... 0
checking diff failure status... 1
checking diff trouble status... 2
checking diff options for RCS... -n
checking diff -L... no
checking diff3 -m... no
checking diff3 library program... configure: error: cannot find a working diff3 library program

Answer 1

I noticed that when I did a which diff3 the program was located here: /usr/bin/diff3.

So to fix, I changed this line in configure:

for i in /usr/*lib*/*diff3*; do

to this:

for i in /usr/*bin*/*diff3*; do

I have not fully tested, but it did compile.
