C++ compiler cannot create executables (solution)

Just thought I would put this question out and supply the answer since I had trouble with it.

While compiling rsyncrypto-1.11, I got the error C++ compiler cannot create executables.

I hadn't installed gcc-c++ AND the extracted file was not chowned to root.

So, if you get this error, check that gcc-c++ is actually installed (rpm -qa |grep gcc) and then change rights on the source code directory (chown -R root:root <path to source directory>).

Yeah, usual Fedora and Red Hat installs won't include gcc, you have to specify it. Also, it's not always needed to change the source directory to root:root. Usually during compile time you're installing as root if you want the program system wide and not for an individual user account, etc.

NEVER compile as the root user!

Presumably you were not compiling. You were running ./configure.

What extracted file?

The first part is correct, but you should NOT be changing the source code to be owned by root. NEVER compile as the root user! You should do the autoconf, ./configure, and make as a normal user, and then do the make install, and ONLY the make install as root.
