Why not fix pkg.m4?

Richard.


Jakub suggested to avoid using pkg-config at all, so we can get rid off this
code altogether.

I thought we'd OK'd pkg-config (for JIT) which is why I didn't call it out.

Looking now, pkg-config got NAKd there and was removed.

Jakub suggested to avoid using pkg-config at all, so we can get rid off this
code altogether.

To re-enable bootstrap with --enable-objc-gc enabled, I checked in this change
as a stop-gap:

as discussed on irc, now avoiding the use pkg-config, and assuming that libgc is
available in default locations when no --with-target-bdw-gc flags are given.
Checked with --enable-objc-gc and --enabled-objc-gc=auto.  Ok to install?

 that's a bit terse. Could you send the complete output for the 
 configuration of
 the libobjc subdir and the config.log?

 I assume that is a configuration with --enable-objc-gc and then the 
 pkg-config
 module cannot be found.  Are gc/gc.h and libgc.so in standard paths without
 having the bdw-gc pkg-config module available? Which libgc version is 
 installed?

There's one more fix needed for the case of only having the pkg-config module
installed when configuring with --enable-objc-gc. We can't use PKG_CHECK_MODULES
directly because the pkg.m4 macros choke on the dash in the module name. Thus
setting the CFLAGS and LIBS directly. Ok to install?

I can confirm, that this works for any configureation not enabling the objc-gc.
I found another issue with enabling objc-gc, but your patch restores the
standard bootstrap.

I see the same failure with just

 ../configure --enable-languages=objc

usually we disable languages (with a diagnostic) if requirements
cannot be fulfilled.

But it seems the default chosen is bad somehow... (and breaks my bootstraps with
default languages).

that's a bit terse. Could you send the complete output for the configuration of
the libobjc subdir and the config.log?

I assume that is a configuration with --enable-objc-gc and then the pkg-config
module cannot be found.  Are gc/gc.h and libgc.so in standard paths without
having the bdw-gc pkg-config module available? Which libgc version is installed?

Thanks, Matthias
