Also provides the 'find_executable()' to search the path for a given executable name. N)DistutilsPlatformErrorDistutilsExecError)DEBUG)logcCsmt|}tjdkr1t||d|n8tjdkrVt||d|ntdtjdS)aRun another program, specified as a command list 'cmd', in a new process. 'cmd' is just the argument list for the new process, ie. cmd[0] is the program to run and cmd[1:] are the rest of its arguments. There is no way to run a program with a name different from that of its executable. If 'search_path' is true (the default), the system's executable search path will be used to find the program; otherwise, cmd[0] must be the exact path to the executable. If 'dry_run' is true, the command will not actually be run. Raise DistutilsExecError if running the program fails in any way; just return on success. posixdry_runntz1don't know how to spawn programs on platform '%s'N)listosname _spawn_posix _spawn_ntr)cmd search_pathverboserr%/usr/lib/python3.4/distutils/spawn.pyspawns rcCs>x7t|D])\}}d|kr d|||ts|}ntjjd || jftjd WYdd} ~ XnXts|}ntjjd |tjd nkxhytj| d\} } Wnutk r} zUddl} | j| jkrcwntsr|}ntd|| jdfWYdd} ~ XnXtj| rts|}ntd|tj | fqtj!| r8tj"| }|dkrdSts|}ntd||fqtj#| rMqqts\|}ntd|| fqWdS)Nrrr$ZMACOSX_DEPLOYMENT_TARGETcSsg|]}t|qSr)int).0xrrr es z _spawn_posix...cSsg|]}t|qSr)r')r(r)rrrr*ks zF$MACOSX_DEPLOYMENT_TARGET mismatch: now "%s" but "%s" during configurezunable to execute %r: %s rz(unable to execute %r for unknown reasonszcommand %r failed: %sz"command %r terminated by signal %dz%command %r failed with exit status %dz1unknown error executing %r: termination status %dr)$rrrr execvpexecvsysplatform _cfg_targetr%Zget_config_varsplit_cfg_target_splitenvirongetrdictexecvpeexecveforkr!rstderrwritestrerror_exitwaitpiderrnoZEINTRrr WIFSIGNALEDWTERMSIG WIFEXITED WEXITSTATUS WIFSTOPPED)rrrrr"Zexec_fnenvZ cur_targetZmy_msgpideZstatusr#r>Z exit_statusrrrr Xs  ""            -    r cCs|dkrtjd}n|jtj}tjj|\}}tjdkrn|dkrn|d}ntjj|sx9|D]1}tjj ||}tjj|r|SqWdS|SdS)zTries to find 'executable' in the directories listed in 'path'.
