procfs fails to compile under Snow Leopard

[hans.ekkehard.plesser@…]

procfs fails to compile under Snow Leopard (OSX 10.6) with several errors in procfs.cc. I get the following error messages:

DEBUG: Assembled command: 'cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_fuse_procfs/work/procfs-2.0" && /usr/bin/make -j2 all'

The complete debugging output is attached. My system is a fresh install with all current updates, i.e. OSX 10.6.2 and XCode 3.2.1.

One thing I am a bit surprised about is that procfs seems to be built using MacOSX10.5.sdk.

This error persists under OSX 10.6.4 with XCode 3.2.3, MacPorts version 1.9.1 and procfs version 2.0.

I have identified the following issues:

• The Makefile for procfs has g++ hardcoded. Thus, procfs is compiled with the currently active compiler, not with the MacPorts default compiler as it should.
• procfs code compiles only if I select g++ 4.0.1. With 4.2.1 (which should be used according to Macports rules) or 4.4 (which I commonly use), several issues occur:
  • g++ 4.4 barfs at -arch options and does not compile anything;
  • g++ 4.2 does not accept goto instructions crossing variable initializations (in functions OPEN_HANDLER(proc__windows__identify) and READ_HANDLER(system__firmware__variables)
  • the system calls IOConnectMethodStructureIStructureO() and IOConnectMethodScalarIScalarO() are not known when using g++ 4.2, even with the 10.5 SDK; they were deprecated for 10.5 and have been removed from 10.6, see ​Apple Developer Documentation; they are replaced by IOConnectCallStructMethod() and IOConnectCallScalarMethod(), but I feel out of my depth here and have not tried to adapt the code.
• Using g++ 4.0.1, compilation goes through, but the resulting code cannot be linked against pcre, which has been built (properly) using 4.2.1.

I hope someone who knows more about MacPorts and OSX internals can fix the Makefiles/Portfile to respect MacPorts conventions about using the default system compiler (ie 4.2.1 for 10.6) and fix those system calls.
