bug#18779: 24.4; Compilation error on Mac OS X Yosemite

[Constantine Vetoshev]

I think something changed between 10.9 (Mavericks) and 10.10
(Yosemite) with include file locations.

After running "./configure --with-ns && make install", the build proceeds until:

gcc -c  -Demacs  -I. -I. -I../lib -I./../lib
-I/usr/include/libxml2          -MMD -MF deps/xml.d -MP   -Wno-switch
-Wno-tautological-constant-out-of-range-compare -Wno-pointer-sign  -g3
-O2  xml.c
xml.c:23:10: fatal error: 'libxml/tree.h' file not found
#include <libxml/tree.h>
         ^
1 error generated.
make[1]: *** [xml.o] Error 1
make: *** [src] Error 2

With the latest Xcode 6.1, symlinking
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include
to /usr/include makes the compilation error go away. The compiled
binary seems to work.

If you don't have anything in /usr/include you havent installed the 
command line tools, which Emacs kind of assumes you have, i.e.

xcode-select --install

Can you confirm this?

You are probably right. I upgraded to XCode 6.1.1 since I filed this
bug report, and either I or it must have done something different:
/usr/include is there and has the header file I was missing before.
It's probably safe to close this ticket; I'll open another one if I
run into trouble with 24.5 prereleases. Thanks!

Ok, closing.

Is it possible/worth it to add some basic sanity-checking to
configure.ac that tests this?

Normally, configure fails badly, can't find compiler and such, if 
command line tools are not installed.  I guess you can compile without 
them, using homebrew or some such (have not tried it), so it is not an 
absolute requirement.

The test for libxml should add -I/Applications/Xcode.app/.... to where 
libxml is, if not in /usr/include.  It is hard to know what failed 
without the full config.log.  I suspect that the config.log is lost.

You suspect correctly. :(
