#25163: gmp clears build_arch -------------------------------------+-------------------------------------- Reporter: ryandesign@… | Owner: mcalhoun@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.99 Keywords: | Port: gmp -------------------------------------+-------------------------------------- gmp clears build_arch: {{{ # if CFLAGS and CXXFLAGS are undefined, configure script tries to build fastest library for build machine. # On PowerPC machines, CFLAGS must be empty to get -force_cpusubtype_ALL. pre-configure { # Set in pre-configure so any universal flags are removed as well. configure.build_arch configure.cflags configure.cxxflags } }}} This causes hilarity for MacPorts 1.9.0 (rc2) when you try to install a dependent of gmp (like mpfr): MacPorts compares the architecture the dependent is about to be built for (e.g. x86_64) with the architecture recorded in the registry that gmp was built for (empty, thanks to the build_arch override in the gmp portfile), sees they don't match, and rebuilds gmp universal: {{{ $ sudo port install gmp ---> Computing dependencies for gmp ---> Fetching gmp ---> Verifying checksum(s) for gmp ---> Extracting gmp ---> Applying patches to gmp ---> Configuring gmp ---> Building gmp ---> Staging gmp into destroot ---> Installing gmp @5.0.1_0 ---> Activating gmp @5.0.1_0 ---> Cleaning gmp $ sudo port install mpfr ---> Computing dependencies for gmp ---> Fetching gmp ---> Verifying checksum(s) for gmp ---> Extracting gmp ---> Applying patches to gmp ---> Configuring gmp ---> Configuring gmp for architecture x86_64 ---> Configuring gmp for architecture i386 ---> Building gmp ---> Building gmp for architecture x86_64 ---> Building gmp for architecture i386 ---> Staging gmp into destroot ---> Staging gmp into destroot for architecture x86_64 ---> Staging gmp into destroot for architecture i386 ---> Computing dependencies for gmp ---> Installing gmp @5.0.1_0+universal ---> Deactivating gmp @5.0.1_0 ---> Cleaning gmp ---> Activating gmp @5.0.1_0+universal ---> Cleaning gmp ---> Computing dependencies for mpfr ---> Fetching mpfr ---> Verifying checksum(s) for mpfr ---> Extracting mpfr ---> Applying patches to mpfr ---> Configuring mpfr ---> Building mpfr ---> Staging mpfr into destroot ---> Installing mpfr @2.4.2-p1_0 ---> Activating mpfr @2.4.2-p1_0 ---> Cleaning mpfr }}} So... don't set build_arch to empty, please; set it to the architecture that the software will be built for (or let MacPorts do so for you). -- Ticket URL: <http://trac.macports.org/ticket/25163> MacPorts <http://www.macports.org/> Ports system for Mac OS
