The idea is that while every "config" command is different, at least they're all named the same, and users always see "config" in the list of standard commands. Also, this is a good place to put common configure-like tasks: "try to compile this C code", or "figure out where this header file lives". s$Id$iÿÿÿÿN(tCommand(tDistutilsExecError(tcustomize_compiler(tlogs.ctcs.cxxsc++tconfigc Bs.eZdZd,d-d.d/d0d1d2d3d4g Zd„Zd„Zd„Zd„Zd„Z d„Z d„Z d„Z d „Z d+d+d+d!d"„Zd+d+d+d!d#„Zd+d+d!d$„Zd+d+d+d+d!d%„Zd+d+d+d+d!d&„Zd+d+d+d+d'd'd(„Zd+d+d+gd)„Zd+d+d!d*„ZRS(5sprepare to builds compiler=sspecify the compiler typescc=sspecify the compiler executables include-dirs=tIs.list of directories to search for header filessdefine=tDsC preprocessor macros to definesundef=tUs!C preprocessor macros to undefines libraries=tls!external C libraries to link withs library-dirs=tLs.directories to search for external C librariestnoisys1show every action (compile, link, run, ...) takens dump-sources=dump generated source files before attempting to compile themcCsLd|_d|_d|_d|_d|_d|_d|_g|_dS(Ni( tNonetcompilertcct include_dirst librariest library_dirsR t dump_sourcet temp_files(tself((s0/usr/lib64/python2.7/distutils/command/config.pytinitialize_options6s       cCsß|jdkr'|jjpg|_n-t|jtƒrT|jjtjƒ|_n|jdkrog|_n$t|jtƒr“|jg|_n|j dkr®g|_ n-t|j tƒrÛ|j jtjƒ|_ ndS(N( RR t distributiont isinstancetstrtsplittostpathsepRR(R((s0/usr/lib64/python2.7/distutils/command/config.pytfinalize_optionsEs  cCsdS(N((R((s0/usr/lib64/python2.7/distutils/command/config.pytrunUscCs½ddlm}m}t|j|ƒs¹|d|jd|jddƒ|_t|jƒ|jrx|jj|jƒn|j r—|jj |j ƒn|j r¹|jj |j ƒq¹ndS(s^Check that 'self.compiler' really is a CCompiler object; if not, make it one. iÿÿÿÿ(t CCompilert new_compilerR tdry_runtforceiN( tdistutils.ccompilerRRRR R RRtset_include_dirsRt set_librariesRtset_library_dirs(RRR((s0/usr/lib64/python2.7/distutils/command/config.pyt_check_compiler]s    cCsdt|}t|dƒ}|rUx|D]}|jd|ƒq*W|jdƒn|j|ƒ|ddkr‚|jdƒn|jƒ|S(Nt _configtesttws#include <%s> s iÿÿÿÿ(tLANG_EXTtopentwritetclose(Rtbodytheaderstlangtfilenametfiletheader((s0/usr/lib64/python2.7/distutils/command/config.pyt_gen_temp_sourcefileps   cCsT|j|||ƒ}d}|jj||gƒ|jj||d|ƒ||fS(Ns _configtest.iR(R3RtextendR t preprocess(RR-R.RR/tsrctout((s0/usr/lib64/python2.7/distutils/command/config.pyt _preprocess}s cCsƒ|j|||ƒ}|jr2t|d|ƒn|jj|gƒ\}|jj||gƒ|jj|gd|ƒ||fS(Nscompiling '%s':R(R3Rt dump_fileR tobject_filenamesRR4tcompile(RR-R.RR/R6tobj((s0/usr/lib64/python2.7/distutils/command/config.pyt_compile„s c Csª|j||||ƒ\}}tjjtjj|ƒƒd} |jj|g| d|d|d|ƒ|jjdk r| |jj} n|j j | ƒ||| fS(NiRRt target_lang( R=RtpathtsplitexttbasenameR tlink_executablet exe_extensionR Rtappend( RR-R.RRRR/R6R<tprog((s0/usr/lib64/python2.7/distutils/command/config.pyt_links"cGsn|s|j}g|_ntjddj|ƒƒx3|D]+}ytj|ƒWq;tk req;Xq;WdS(Ns removing: %st (RRtinfotjoinRtremovetOSError(Rt filenamesR0((s0/usr/lib64/python2.7/distutils/command/config.pyt_cleanœs    RcCsbddlm}|jƒd}y|j||||ƒWn|k rSd}nX|jƒ|S(sQConstruct a source file from 'body' (a string containing lines of C/C++ code) and 'headers' (a list of header files to include) and run it through the preprocessor.
