encfs @1.9.5: clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.0'

[astir13 (Stefan Pielmeier)]

I encountered a failing encfs build on big sur (other ports like e.g. xclock nicely build and install):

sudo port install encfs

--->  Some of the ports you installed have notes:
  libpsl has the following notes:
    libpsl API documentation is provided by the port 'libpsl-docs'.

checking the logs provides:

clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.0'

A workaround I found:

• go into the build directory: cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_fuse_encfs/encfs/work/build
• and run command cmake
• then make
• then make install
• worked for me, I have a working encfs now ;-)

Replying to astir13:

clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.0'

This means your command line tools are out of date (are for a version of macOS older than macOS 11). There is a bug in macOS that does not update the command line tools automatically so please update them manually. See ProblemHotlist#reinstall-clt.

A workaround I found:

• go into the build directory: cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_fuse_encfs/encfs/work/build
• and run command cmake
• then make
• then make install
• worked for me, I have a working encfs now ;-)

When you did this, cmake and make and make install did not run with the arguments and environment variables that MacPorts would have set, so what you have now installed is probably different than what would have been installed by MacPorts, so we cannot support such an installation.
