#49198: netcdf @4.3.3.1_2 +dap +netcdf4 +gcc49/+gcc5 test fails -------------------------+----------------------- Reporter: dstrubbe@… | Owner: takeshi@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: netcdf | -------------------------+----------------------- Comment (by piergiuseppe.fogli@…): I have a similar problem with netcdf @4.3.3.1_4+dap+gcc5+netcdf4 using MacPorts 2.3.4 on El Capitan (10.11.1). The installation process seems OK, but I have problems running ncdump or other software using the netcdf library (nco, cdo, ncview, ...). [[BR]] gdb gives the following error: {{{ sudo gdb --args ncdump -h foo.nc Reading symbols from ncdump...(no debugging symbols found)...done. (gdb) run Starting program: /opt/local/bin/ncdump -h foo.nc netcdf foo { dimensions: time = UNLIMITED ; // (120 currently) latitude = 180 ; longitude = 360 ; nv = 2 ; variables: Program received signal SIGSEGV, Segmentation fault. 0x00007fff909c12da in stack_not_16_byte_aligned_error () from /usr/lib/system/libdyld.dylib (gdb) where #0 0x00007fff909c12da in stack_not_16_byte_aligned_error () from /usr/lib/system/libdyld.dylib #1 0x000000000000001c in ??

Might the stack_not_16_byte_aligned_error error be related to the [[https://trac.macports.org/ticket/44596#comment:35|Libtool MACOSX_DEPLOYMENT_TARGET bug]] happening on El Capitan (10.11)? -- Ticket URL: <https://trac.macports.org/ticket/49198#comment:2> MacPorts <https://www.macports.org/> Ports system for OS X
