Unable to build git on Lion - missing config.h from Perl header files

Unable to build git on Lion - missing config.h from Perl header files

[Sorin Sbarnea]

Hi,

I came across the following problem while trying to build git (1.7.6) on Lion
https://github.com/mxcl/homebrew/issues/7091

The only files existing in
/System/Library/Perl/5.12/darwin-thread-multi-2level/CORE/ are
libperl.dylib andperl.h.

make[2]: *** No rule to make target
`/System/Library/Perl/5.12/darwin-thread-multi-2level/CORE/config.h',
needed by `perl.mak'.  Stop.
make[1]: *** [instlibdir] Error 2

If possible it would be a good idea to continue the discussion on
homebrew bug tracker

Thanks,

Did you upgrade to lion from a system where you were building previously? Did you try "make clean"?

This was a clean-new Lion install, not an upgrade. I just installed
Xcode on alternate location /Developer41 instead of /Developer

Yes, I did a `make clean` but it has no effect.

The problem is that on Lion there is no config.h in the perl
directory, only a perl.h file.

Color me puzzled, but where is it getting the config.h idea from?

  $ git grep config\\.h
  compat/fnmatch/fnmatch.c:# include <config.h>
  compat/regex/regex.c:#include "config.h"
  t/t4014-format-patch.sh:test_expect_success '--no-add-headers overrides config.headers' '

Similarly, 'git grep config perl' only turns up matches in perl code.
So what tells it to use config.h?

Probably MakeMaker.

Setting NO_PERL_MAKEMAKER may help:

   rm perl/perl.mak
   make NO_PERL_MAKEMAKER=1

I confirm that this workaround solved the problem. Now the question is
what should be changed so git will be installed (and build) without
problems by homebrew?

Thanks

If the user's distro does not have packaged makemaker, or if the user
chooses not to install it, then the build procedure of git can be told to
avoid using it, which is what you did. So there is nothing to fix there.

If you are not going to tell git to avoid makemaker, in other words, if
you want to use makemaker, then installing it before starting the build
procedure would help, too. But that is outside the scope of git project.

Please do not top post.

I got the impression that his system did have makemaker, and that it
created the perl.mak file, but then building git failed because some
header files were missing from his perl installation.

Earlier he said:

I don't have access to a mac, but on my system I have many header files
in .../x86_64-linux-thread-multi/CORE/ including config.h.  These files
are part of the base perl installation rpm (i.e. not some -devel rpm).

But like you said, there is nothing to fix on the git side of things.
