This version installs headers outside \ of the normal filesystem hierarchy in order to not accidentally conflict \ with the host implementation that other ports may expect. homepage http://blog.llvm.org/2013/10/new-libunwind-implementation-in-libcabi.html master_sites http://www.llvm.org/releases/${version}/ dist_subdir llvm use_xz yes distname ${name}-${version}.src checksums rmd160 0181a9c886032a9a24a35e4286d99bf64917eff6 \ sha256 66675ddec5ba0d36689757da6008cb2596ee1a9067f4f598d89ce5a3b43f4c2b use_configure no patch.pre_args -p1 patchfiles \ 0001-libunwind-Add-missing-include-of-libunwind_ext.h-to-.patch \ 0002-libunwind-Use-__builtin_trap-rather-than-__builtin_u.patch \ 0003-libunwind-ppc-build-fix.patch \ 0004-libunwind-Only-include-Availability.h-on-Leopard-and.patch \ 0005-libunwind-MacPorts-availability.patch \ 0006-MacPorts-Makefile.patch \ 0007-libunwind-Fix-fallback-implementation-of-_dyld_find_.patch \ 0008-Define-__STDC_FORMAT_MACROS-to-bring-in-format-macro.patch \ 0009-config.h-Add-missing-include-of-stdint.h-for-uint64_.patch \ clang-3.4-workaround.patch post-patch { if {${os.major} < 9} { foreach reg {cr ctr eax ebp ebx ecx edi edx eip esi esp lr mq r0 r1 r10 r11 r12 r13 r14 r15 r16 r17 r18 r19 r2 r20 r21 r22 r23 r24 r25 r26 r27 r28 r29 r3 r30 r31 r4 r5 r6 r7 r8 r9 rax rbp rbx rcx rdi rdx rip rsi rsp srr0 srr1 vrsave xer} { reinplace "s|__${reg}|${reg}|g" ${build.dir}/Registers.hpp } } } build.dir ${worksrcpath}/src destroot.dir ${build.dir} if {${subport} == "${name}-headers"} { supported_archs noarch build {} destroot.target installhdrs destroot.args \ PREFIX="${prefix}" } else { # Technically not needed, but subports will expect depending on libunwind to pull in the headers depends_lib-append port:libunwind-headers # clang 3.5 and newer are blacklisted to prevent dependency cycles foreach ver {3.5 3.6 3.7 3.8 3.9} { if {![file exists ${prefix}/bin/clang-mp-${ver}]} { compiler.blacklist-append macports-clang-${ver} } } # https://trac.macports.org/ticket/49779#comment:3 compiler.blacklist-append {clang < 100} *gcc-4.\[0123456\] variant universal {} default_variants +universal set cxx_stdlibflags {} if {[string match *clang* ${configure.cxx}]} { set cxx_stdlibflags -stdlib=${configure.cxx_stdlib} } set asflags {} if {[variant_isset universal] && [lsearch ${universal_archs} ppc] != -1} { if {[string match *clang* ${configure.cc}]} { set asflags "-fno-integrated-as" } } if {${os.major} < 11} { # Snow Leopard's libSystem's libmacho does not contain getsectiondata() depends_build-append port:libmacho configure.cppflags-append -DUSE_MACPORTS_LIBUNWIND configure.ldflags-append -lmacho } configure.cflags-append -std=gnu99 build.args \ PREFIX="${prefix}" \ CC="${configure.cc}" \ CXX="${configure.cxx}" \ CPPFLAGS="${configure.cppflags} -DNDEBUG" \ CFLAGS="${configure.cflags}" \ CXXFLAGS="${configure.cxxflags} ${cxx_stdlibflags}" \ ASFLAGS="${asflags}" \ LDFLAGS="${configure.ldflags} ${cxx_stdlibflags}" \ RC_ARCHS="[get_canonical_archs]" \ LIBUNWIND_CURRENT_VERSION=${version} if {[vercmp $xcodeversion 3.2] < 0 && [string match "*macports*" ${configure.compiler}]} { # Xcode 3.1.4 fails with load commands in the newer toolchain depends_build-append port:cctools build.args-append \ AR=${prefix}/bin/ar \ RANLIB=${prefix}/bin/ranlib } destroot.target installlibs destroot.args \ PREFIX="${prefix}" \ STRIP_ON_INSTALL="NO" } livecheck.type none
