[Texmacs-dev] OSX compile

[Michael Lachmann]

I had some problems with the OSX compile on 10.9 using Xcode 4.3.6
(Apple switched compilers, and lots of things broke.)
compiling when using the configure flag --enable-macosx-distr fails.

One of the errors looks like this:

(the problem only occurs when the -mmacosx-version-min= flag is used)

If you google this type of error, you'll see that many projects encountered the 
problem.
It could be that updating to a new version of QT will fix the problem.

A fix that worked for me is following:
http://www.cocoawithlove.com/2009/09/building-for-earlier-os-versions-in.html

and adding 
-isysroot 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk

to the CXX_FLAGS and BFLAGS.
MacOSX10.7.sdk worked for me for compiling with min version 10.4, but I haven't 
actually checked the result on 10.4 -- I don't have earlier versions of the sdk 
installed on my system. I'm also not sure that the path to the sdk
will always be the same - on my system it is in the Xcode app, but the web site 
above had it in 
/Developer/SDKs

So, I'm not sure what is the best way to fix the configure script.
But, using this change, 
configure --enable-macosx-distr   --enable-macosx-extensions --enable-qtpipes 
--enable-pdf-renderer
make MACOS_PACKAGE
finished successfully.

Here's a diff of my configure script:
