Ok, I changed the topic to reflect the new attempt. MacPorts has been uninstalled as per instructions, and reinstalled. I am now attempting to run https://trac.macports.org/wiki/LibcxxOnOlderSystems in order to support software that may be written according to C++11 standard.
I ran step 2 as corrected. No error reported. I ran step 3.1. No error reported at either step (3.1.1 and 3.1.2). Edited /opt/local/etc/macports/macports.conf as per step 3.2: The beginning of the file now looks like: cxx_stdlib libc++ buildfromsource always delete_la_files yes default_compilers macports-clang-3.4 macports-clang-3.3 gcc-4.2 apple-gcc-4.2 gcc-4.0 # $Id: macports.conf.in 117120 2014-02-17 00:55:33Z j...@macports.org $ […] Then step 3.3. Received: Error: No ports matched the given expression I assumed it was normal since this is a fresh installation, no port has been inactivated by step 3.1.1. Then step 3.4: was long and noisy, but received no error. Then step 3.5: no error Then step 3.6: no error Then step 3.7: It says to edit /opt/local/etc/macports/macports.conf again ; mine now looks like cxx_stdlib libc++ buildfromsource always delete_la_files yes default_compilers macports-clang-3.7 macports-clang-3.4 macports-clang-3.3 gcc-4.2 apple-gcc-4.2 gcc-4.0 # $Id: macports.conf.in 117120 2014-02-17 00:55:33Z j...@macports.org $ As I understand it, this is the last step. Then I tried to install Xsane, but it failed; I will open another thread so as to keep this one clean.
