#40003: wgrib2: build fails when nonexistent universal variant is selected --------------------------+----------------------- Reporter: ryandesign@… | Owner: takeshi@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.0 Keywords: haspatch | Port: wgrib2 --------------------------+----------------------- The wgrib2 port advertises no universal variant: {{{ $ port variants wgrib2 wgrib2 has the variants: g95: build iplib with g95 (alpha) * conflicts with gcc44 gcc45 gcc46 gcc47 gcc48 gcc44: build iplib with gcc44 (alpha) * conflicts with g95 gcc45 gcc46 gcc47 gcc48 gcc45: build iplib with gcc45 (alpha) * conflicts with g95 gcc44 gcc46 gcc47 gcc48 gcc46: build iplib with gcc46 (alpha) * conflicts with g95 gcc44 gcc45 gcc47 gcc48 gcc47: build iplib with gcc47 (alpha) * conflicts with g95 gcc44 gcc45 gcc46 gcc48 gcc48: build iplib with gcc48 (alpha) * conflicts with g95 gcc44 gcc45 gcc46 gcc47 gcc48 }}} Nevertheless the port tries to build universal when I select the (nonexistent) universal variant, and then fails: {{{ ld: warning: ignoring file /opt/local/var/macports/build/_Users_rschmidt_macports_dports_science_wgrib2/wgrib2/work/grib2/g2clib-1.4.0/libgrib2c.a, file was built for archive which is not the architecture being linked (x86_64): /opt/local/var/macports/build/_Users_rschmidt_macports_dports_science_wgrib2/wgrib2/work/grib2/g2clib-1.4.0/libgrib2c.a Undefined symbols for architecture x86_64: "_dec_png", referenced from: _unpk_grib in unpk.o "_enc_jpeg2000", referenced from: _jpeg2000_grib_out in jpeg_pk.o "_g2_free", referenced from: _main in wgrib2.o "_g2_getfld", referenced from: _main in wgrib2.o "_g2_unpack3", referenced from: _f_gdt in GDT.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) }}} Either add a functional universal variant (perhaps with the help of the muniversal portgroup or patches to the build system) or remove the parts of the portfile that react to the universal variant selector. The attached patch does the latter (and also fixes a problem where the build wasn't using `-arch` flags when calling the linker). -- Ticket URL: <https://trac.macports.org/ticket/40003> MacPorts <http://www.macports.org/> Ports system for OS X
