Re: [Texmacs-dev] OSX compile

[Miguel de Benito Delgado]

Hi, with XCode 4.6.3 in 10.7.5 and with XCode 5 in 10.9 I don't see this problem  (though I don't recall right now whether I have that flag on in my laptop...) . Neither do I experience it building with make... (?)

In any case, if one wants to fix the configure process, it has to be done in configure.in, which is fed to autotools and automagically produces the configure script. However, hardcoding paths is definitely not an option, so I guess the proper thing to do is to add some warning that the user needs to set a particular environment variable or something like that.

Best,

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:
