[lxml-dev] building lxml for OS X 10.4 on PPC?
Hello, I am desperately trying to build lxml on a Mac PPC with OS X 10.4. It is not the most current plattform, but I am stuck with it... I tried "STATIC_DEPS= true easy_install lxml", which works perfectly on all Intel machines I have access to. But unfortunately there seems to be a problem with libiconv on the PPC side. Has anyone else had success? I searched the archives for any hints on building with this combination, but didn't find a solution/suggestions. Should I try something similar to "./configure --without-iconv"? But how would I pass this to easy_install? Or maybe try a local static build including not only libxml2 and libxslt but libiconv as well? Any help is greatly appreciated! and sorry for bothering you with these newbee questions. Pascal

I built lxml several months ago on my Tiger G5 without any problems. What error do you get exactly? Kind regards, Michael

I get the following "last lines" (below) during compiling libxml2, where I suppose the important bit is:
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning /usr/lib/libiconv.dylib cputype (18, architecture ppc) does not match cputype (7) for specified -arch flag: i386 (file not loaded)
This is a PPC G5, 2Ghz, 1GB, 10.4.11, XCode 2.5. Maybe I got an incompatible libiconv installed by a previous version of Apple's DevTools? I am really wildly guessing here... Thanks a lot. Pascal <snip>

Ok, I was able to reproduce the problem. I also have a quick fix but it's more a hack than anything else. First the problem. During the creation of the static libxml.a library libtool also creates an libxml2.la file. libtool finds /usr/lib/libiconv.la which defines /usr/lib/ libiconv.dylib above. Now this file is no fat-binary and just has the PCC architecture. As a workaround rename /usr/lib/libiconv.la or move it somewhere else, build lxml and move/rename the file back. This way the "correct" libiconv.dylib will be used. I think the most proper fix would be to build libiconv as part of the static-deps as well. Stefan what do you think? Kind regards, Michael

This allowed me to build on a G4 PPC and a G5 PPC Mac. Thanks! The very last step: "Building against libxml2/libxslt in the following directory: /private/tmp/easy_install-W57UyT/lxml-2.2.2/build/tmp/libxml2/lib" takes quite long. Is this expected behaviour? I will do some testing over the weekend. Please let me know if I can do some testing etc. Best regards & again: thanks! Pascal
