vstr build failure with clang: ld: duplicate symbol _vstr_ref_del in .libs/fix.o and .libs/assert_loop.o

[djcc04@…]

On running sudo port install vstr, I receive an error linked to a duplicate object in the build. Find the output in the terminal below. I have attached the main.log file.

Hi Ryan,

I installed macports clang, and added the modification to the Portfile. I still get a build error. It is still the duplicate object, however it is reported by clang. I've added my Portfile below the break to make sure I've added the lines correctly.

:info:build ld: duplicate symbol _vstr_ref_del in .libs/fix.o and .libs/assert_loop.o for architecture x86_64
:info:build clang: error: linker command failed with exit code 1 (use -v to see invocation)

Portfile:

new main.log of vstr

Sorry, I committed the wrong block in r89327. Fixed in r89343.

You don't need to manually modify your Portfile, nor install a MacPorts clang port (unless you want to use MacPorts clang for your own compilation needs outside of MacPorts; MacPorts itself does not use the compilers installed by the MacPorts clang ports). All you need to do is wait 30 minutes, then run "sudo port selfupdate" and "sudo port clean vstr" and try again.
