Hi, I have just compiled glib-2.0.1 on Mac OS 10.1.4 (build 5Q125), and I thought you might be interested in the following comments. First, by default on Mac OS 10.1, the linker flag -twolevel_namespace is assumed. Libtool (at least the version you are using, and until 2 months ago; I haven't tested the latest libtool release) uses the flag "-undefined suppress", which is only allowed in flat namespace binaries. The solution is to either specify "-undefined error" in LDFLAGS and make sure it is also passed correctly when calling the linker from libtool, and ensuring that there are no undefined symbols when linking; or specifying "-flat_namespace -undefined suppress" in libtool's allow_undefined_flag. Secondly, it is recommended to use the "-no-cpp-precomp" compiler switch, which turns off Apple's preprocessor and uses the gcc default one instead. The Apple precompiler chokes on everything non-Apple, it seems (indicated by a lot of "cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode" messages), so better not use it in the first place. And lastly, which was the only "real" problem, there is a problem with libtool. I do not know what exactly happens, but some convenience libraries end up _twice_ on the commandline, resulting in linker errors. The dirty hack I used was to patch libtool so that the duplicate entries are removed (see attachment) -- the real solution would be to investigate what happens. :) Since I just needed glib up and running, I will leave this as an exercise to the interested reader. I think that the Fink people (fink.sf.net) have glib-1.2 in their distribution, which means that they probably found a clean solution to the libtool problem mentioned above. I do not know if you are in contact with them, or if you are interested in supporting Mac OS X at all. If you want, I can take a look at how they solved it and report back to you -- but I do not want to spend that time and then find out that you don't consider Darwin / OS X to be of any interest anyway. Well, I just thought you might be interested in getting some feedback. Thanks for the great work you keep doing! Best regards, #!/kyrah -- Karin Kosina (vka kyrah) http://kyrah.net
