Also provides the 'find_executable()' to search the path for a given executable name. s$Id$iN(tDistutilsPlatformErrortDistutilsExecError(tDEBUG(tlogiicCst|}tjdkr1t||d|nZtjdkrVt||d|n5tjdkr{t||d|ntdtjdS(sRun 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. tposixtdry_runtnttos2s1don't know how to spawn programs on platform '%s'N(tlisttostnamet _spawn_posixt _spawn_ntt _spawn_os2R(tcmdt search_pathtverboseR((s%/usr/lib/python2.7/distutils/spawn.pytspawns cCs>x7t|D])\}}d|kr d|||tj}qGntj} | dkry0|dkr~|||n||||WnLtk r} ts|}ntjjd|| jftjd nXts|}ntjjd |tjd nIxFytj| d\} } Wn]tk r} d dl}| j|jkrfqntsu|}ntd || d fnXtj | rts|}ntd |tj!| fqtj"| r tj#| }|dkrdSts |}ntd||fqtj$| r5qqtsD|}ntd|| fqdS(NRiR"tMACOSX_DEPLOYMENT_TARGETtt.sF$MACOSX_DEPLOYMENT_TARGET mismatch: now "%s" but "%s" during configuresunable to execute %r: %s is(unable to execute %r for unknown reasonsiscommand %r failed: %ss"command %r terminated by signal %ds%command %r failed with exit status %ds1unknown error executing %r: termination status %d(%RRRR texecvptexecvtNonetsystplatformt _cfg_targetR#tget_config_vartsplittintt_cfg_target_splittenvirontgetRtdicttexecvpetexecvetforkRRtstderrtwritetstrerrort_exittwaitpidterrnotEINTRRt WIFSIGNALEDtWTERMSIGt WIFEXITEDt WEXITSTATUSt WIFSTOPPED(RRRRRtexec_fntenvtxt cur_targettmy_msgtpidtetstatusR R<t exit_status((s%/usr/lib/python2.7/distutils/spawn.pyR ts  ..               cCs|dkrtjd}n|jtj}tjj|\}}tjdksdtj dkr}|dkr}|d}ntjj |sx9|D]1}tjj ||}tjj |r|SqWdS|SdS(sTries to find 'executable' in the directories listed in 'path'.
