I am trying to build myself a new version of rsync 3.1.1 under Mac OS 10.10.3, as the mac comes with an older version, and the project does not distribute binaries.
I followed this simple script but it hiccups on gcc. (I am not sure why — though I removed XCode to save disk space, I have the command line tools, incl. gcc in /usr/bin etc.) I would try to build it with clang instead, but how exactly shall I do that?
Here is the error from the script:
configure.sh: Configuring rsync 3.1.1

By the way, I know I could have just stuck with Homebrew, but now I want to learn.
clang
would be irrelevant here.gcc --version
show Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)gcc
that comes with Xcode is actuallyclang
. :) I'd trybrew uninstall gcc
, thenxcode-select --install
, then try./configure
again. Your system just appears to be a bit confused right now.
