Hi all,
Kudos to all who work on this most valuable project. Now, back to
whining... :-)
Still failing to get 64-bit MacPorts to work properly, I though I'd
relay my progress so far. The short story is some ports do not compile
properly as ppc64. Others do, but don't compile properly on x86_64.
I'm prepared, of course, to notify the individual maintainers of these
ports, but first I'd like your opinion on whether my general strategy
is sound.
Note: I've given up the "universal" strategy using MacPorts 1.7
(trunk) for the time being, as I can't even get '+universal' to work
on Leopard (see this post: http://lists.macosforge.org/pipermail/macports-dev/2008-March/004704.html)
. But maybe this is a known issue?
* Case 1: Installing ppc and ppc64 binaries in separate directories
Environment: OS X Server 10.5.2, MacPorts 1.6, Dual G5 PM.
- Installing from disk image to /opt/local produces a working MacPorts
installation. I use this to install 32-bit binaries and libraries.
- Installing a second 1.6 MacPorts from source to /opt/local-64/,
following the instructions in the MacPorts Guide also works fine,
configured as follows:
# ./configure --prefix=/opt/local-64 --with-tclpackage=/Library/Tcl/
macports-64
- I then edit /opt/local-64/share/macports/Tcl/port1.0/
portconfigure.tcl:
default configure.m64 yes
default configure.mtune {"G5"}
- The following ports (prerequisites) now produce ppc64 binaries and
libraries. Manual compilation of ppc64 binaries depending on these
libraries also work fine.
expat, libiconv, gettext (w/ deps), popt
- Trying to install 64-bit "R", I fail on some dependencies:
"gmp" builds, but needs to be edited as follows:
configure.env ABI=mode64
"mpfr" builds.
"gcc42" (for some reason a library and compiler dependency) I cannot
get it to to compile on 64-bit. Some stages produce ppc64 object files
but some ignore the -m64 flag and build ppc object files. Needless to
say, the linker is not happy.
* Case 2: Installing i386 and x86_64 "universal" binaries.
Environment: OS X 10.5.2, MacPorts 1.6, CoreDuo MBP (32-bit machine, I
know!)
- Installed MacPorts 1.6 from disk image into /opt/local, then editing
the following files:
variants.conf:
added +universal
portconfigure.tcl
set/added "-arch i386 -arch x86_64" in default variables:
configure.universal_cflags, configure.universal_cxxflags,
configure.universal_ldflags
- Trying to install 64-bit "R", I fail on some dependencies:
"gmp" builds, but needs to be edited as follows. This is reasonable,
as this port does not have a universal variant, plus I'm on a 32-bit
machine:
configure.cflags-append -m64
"mpfr" fails in the configure stage: "configure: error: libgmp not
found or uses a different ABI". I suspect this is due to the configure
script trying to compile and run a 64-bit code snippet, which of
course will fail on the CoreDuo. I will try to get my hands on a
proper x86_64 machine and let you know how it turns out.
"gcc42" depends on mpfr, so this has not been tested yet.
Any feedback is appreciated. A 64-bit clean MacPorts would (in my
view) be a significant improvement to an already great tool.
TIA,
/Emil
