#47754: Vigra @1.10.0_6 build fails -------------------------+------------------------------- Reporter: macports@… | Owner: benjamin.seppke@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.3 Resolution: | Keywords: Port: vigra | -------------------------+------------------------------- Comment (by benjamin.seppke@…): Hello, you are right - and I was still confused regarding my last post. I edited it to avois any confusion here. The error arises for the error (?!) inside the cmake defaults w.r.t. the clang++ build chain. In the default setting, this results in a CMakeCache.txt build config for Release like: {{{ CMAKE_CXX_FLAGS_RELEASE -pipe -Os -DNDEBUG }}} In the -Os optimization level some symbols of the std c++ lib are somehow lost. But if you replace the -Os with e.g. -O3 optimization, it compiles just as expected. I have appended a Portfile-patch to this ticket, which solves this issue for me. Feel free to try it out and - if successful - please patch the macports Portfile for me. Unfortunately, I don't have write priviledges there. -- Ticket URL: <https://trac.macports.org/ticket/47754#comment:8> MacPorts <https://www.macports.org/> Ports system for OS X
