https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199746 Bug ID: 199746 Summary: [patch] mail/evolution builds but does not run on FreeBSD 8.4 (and probably 9.3) Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: gnome@FreeBSD.org Reporter: truckman@FreeBSD.org Flags: maintainer-feedback?(gnome@FreeBSD.org) Keywords: patch Assignee: gnome@FreeBSD.org Created attachment 156058 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=156058&action=edit patch to fix evolution startup error on FreeBSD 8.4 The addition of USES=compiler:c++11-lib to evolution/Makefile in r377107 unbroke the build on FreeBSD 8.4, but it fails to run and throws this error: %evolution /libexec/ld-elf.so.1: /usr/lib/libstdc++.so.6: version GLIBCXX_3.4.14 required by /usr/local/lib/libwebkitgtk-3.0.so.0 not found The build was fixed because USES=compiler:c++11-lib adds -L/usr/local/lib/gcc48 to LDFLAGS, so ld finds the version of libstdc++ that is bundled with the gcc port. It also adds /usr/local/lib/gcc48 to evolution executable rpath. This does not fix the runtime problem because evolution seems to only contain C code and does not get linked to libstdc++. This seems to cause rtld to ignore the /usr/local/lib/gcc48 rpath of the executable. When rtld is loading the shared libraries that are directly referenced by evolution, the first of those that references libstdc++ governs which version of libstdc++ is loaded. If that shared library was linked to libstdc++ in base, then the base version gets loaded, and when libwebkitgtk-3.0 is loaded, it does not get the newer version of libstdc++ that it expects. In this case, the first shared library loaded by rtld for evolution that wants libstdc++ is /usr/local/lib/libebook-1.2, which is part of databases/evolution-data-server, and it is linked to the base version of libstdc++. If evolution-data-server is built with USES=compiler:c++11-lib, then it has /usr/local/lib/gcc48 added to its rpath, which causes libstdc++ from the gcc port to get loaded. That satisfies the requirements for webkit-gtk3 and allows evolution run. It is not necessary to make this conditional on OSVERSION and doing so will not fix the problem in some corner cases. When building on FreeBSD 10 and higher where the base compiler is clang, USES=compiler:c++11-lib is basically a no-op and is therefore harmless. I believe that building FreeBSD 10 with the base gcc compiler (and without clang) is supposed to be supported on amd64 and i386, and is mandatory on some of the tier 2 platforms that clang does not support. In this case, USES=compiler:c++11-lib is needed to avoid the same breakage as on FreeBSD 8 and 9. -- You are receiving this mail because: You are the assignee for the bug.
