#38374: boost: stdlibc++ linkage prevents dependencies from using libc++ ----------------------------+--------------------------- Reporter: macportbugs@… | Owner: adfernandes@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.3 Resolution: | Keywords: Port: boost | ----------------------------+--------------------------- Comment (by adfernandes@…): Okay - here is my (trivial) portfile patch. {{{ --- Portfile (revision 104122) +++ Portfile (working copy) @@ -89,12 +89,11 @@ reinplace -E "s|-install_name \"|&${prefix}/lib/|" \ ${worksrcpath}/tools/build/v2/tools/darwin.jam - if {[string length ${configure.sdkroot}] == 0} { - write_jam "using darwin : : ${configure.cxx} : : ;" - } else { - write_jam "using darwin : : ${configure.cxx} : <compileflags>\"-isysroot ${configure.sdkroot}\" : ;" - } + set compileflags "" + if {[string length ${configure.sdkroot}] != 0} { set compileflags "<compileflags>\"-isysroot ${configure.sdkroot}\"" } + write_jam "using darwin : : ${configure.cxx} : <cxxflags>\"${configure.cxxflags}\" ${compileflags} <linkflags>\"${configure.ldflags}\" : ;" + } }}} The problem with it is that it replaces the `boost`-default `-O3` optimization level with `-O2`. No big deal, really... except one never really knows what they've assumed (in the threading libraries, etc etc etc) about optimization levels. You get libraries built with {{{ "/usr/bin/clang++" -ftemplate-depth-128 -O2 -O3 -finline-functions -Wno- inline [...] }}} So if we assume that the last-most specified `-O3` flag is the one in effect, which it should be, then this is just fine.
