--------------------+--------------------------------
 Reporter:  nf6x@…  |      Owner:  macports-tickets@…
     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.2
 Keywords:          |       Port:  dosbox
--------------------+--------------------------------
 After upgrading to Yosemite and XCode 6.1, dosbox failed to build with the
 following output:

 {{{
 ...emulators/dosbox% sudo port install dosbox
 Warning: All compilers are either blacklisted or unavailable; defaulting
 to first fallback option
 --->  Computing dependencies for dosbox
 [...]
 --->  Configuring dosbox
 Warning: All compilers are either blacklisted or unavailable; defaulting
 to first fallback option
 [...repeated many times...]
 --->  Building dosbox
 Error: org.macports.build for port dosbox returned: command execution
 failed
 Please see the log file for port dosbox for details:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_emulators_dosbox/dosbox/main.log
 [...]
 Error: Processing of port dosbox failed
 }}}

 Log file included several instances of errors similar to this one:

 {{{
 :info:build ./core_dyn_x86/../../fpu/fpu_instructions_x86.h:1165:2: error:
 ambiguous instructions require an explicit suffix (could be 'filds', or
 'fildl')
 }}}

 Applying the fpu.diff patch provided in ticket 40789 (attached for
 convenience) and removing the clang blacklist statement from the Portfile
 (new patch attached) allowed a clean build.
