Anders, what do you think needs to change to make compiling on OSX run smoothly?
My preferred method of compiling both wxWidgets and wxLua is to create
a dir "wxLua/config_osxud" (unicode, debug) and then running
$../configure --prefix=/Users/john/.../wxLua/config_osxud
$make
so everything is nicely within the config_osxud dir and I can quickly
delete that to start over.
I create a link ~/bin/wx-config -> to my preferred wx-config, where
~/bin in first in my bash path.
Ok, so this is not "standard" as opposed to installing to a "system"
dir like /usr/local , but I do not want to have to dig out and delete
the installed files when drastic changes are necessary.
So... anyway
1) I see that after running the above that wxLua.app (all the apps)
are installed into apps/. Should we change the target, for example,
wxLua.app/Contents/PkgInfo in the generated apps/Makefile to create
wxLua.app in bin/ ?
2) What is the deleting and moving part of
distrib/macbundle/copydylibs.command supposed to do?
I think it assumes that you've run $./configure in the root dir of wxLua.
$cd distrib/macbundle
$copy ../lib/*.dylib . <--- ? should be ../../lib/*.dylib ?
$rm libwxlua_macud_wxlua_2.8.0.dylib <- the symbolic link
What about the other symbolic link libwxlua_macud_wxlua_2.8.dylib?
$mv real lib to *0.dylib
I get what the install_name_tool parts are doing.
If I understand correctly we want the real dylibs renamed to
reallibname.0.dylib, which was originally a link. Finally where does
all these libs go? When the script ends it looks like they'll still be
in distrib/macbundle.
3) After compiling with the above method, wxLua.app segfaults because
it's confused about what dynamic libs to use. When I run
$otool -L wxLua.app/Contents/MacOS/wxLua
I see that it's linked to all my wx-config libs except for
/usr/lib/libwx_macud_stc_2.8.0.dylib and same for the gl lib. Ugh. I
see that the Osx replacement for LD_LIBRARY_PATH is dyld, but is there
a simpler way? Do you not have this problem?
Thanks,
John
