python25 +universal, not compiling

[andre.david@…]

Hi,

I was trying to get a x86_64 binary of python, so I decided to install python25 +universal, which stops with:

checking size of wchar_t... configure: error: cannot compute sizeof (wchar_t), 77
See `config.log' for more details.
Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_python25/work/Python-2.5.1" && ./configure --prefix=/opt/local --enable-shared --mandir=/opt/local/share/man --disable-framework --enable-universalsdk " returned error 1

The log indicates:

configure:19754: checking size of wchar_t
configure:20079: /usr/bin/gcc-4.0 -o conftest -O2 -I/opt/local/include -D__DARWIN_UNIX03 -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -L/opt/local/lib
 conftest.c  >&5
ld: library not found for -lcrt1.10.5.o
collect2: ld returned 1 exit status

so I looked around and found ​http://trac.macports.org/projects/macports/ticket/13475 . I applied the patch to both files I found (gotta brush up on the organization...)

$ grep "10\.4" `locate portconfigure.tcl`
/opt/local/share/macports/Tcl/port1.0/portconfigure.tcl:    set sysroot "/Developer/SDKs/MacOSX10.4u.sdk"

and the error persists.

Any ideas?

Thanks,

Andre

At least in MacPorts 1.6.0: The solution is not found by changing the port configuration, since the issue is in Python's 'configure' script. 'gcc' in 10.4 and prior, for some reason, worked setting '-isysroot' to the SDK of choice. At least in XCode 2.4.1, the '-isysroot' is not in the documentation, but it still works. In XCode 2.5 (for 10.5), '-isysroot' no longer works; its replacement is '-isystem'. Changing this in the 'configure' script (as well as a couple other changes elsewhere) fixes the +universal install for 10.5.

Ticket #11267 provides a tarball that (at least in my testing) allows for python25 +universal, +framework, +universal+framework, or just plain; for both 10.4 (using the 10.4SDK for +universal) and 10.5 (using the 10.5SDK for +universal); all combinations of variants seem to work correctly. While the resulting binaries using +universal are for "i386" and "ppc", it would not be difficult to add variants to do "ppc64" and "x86_64" (though, of course, 64-bit apps are not well-tested on OSX just yet).

This is not strictly true, on Leopard -isysroot still works in Xcode 2.5 and in Xcode 3.0 ?

I had a ton of issues attempting to build python24 and python25 as universal (10.4) binaries... and eventually I came up with a VERY EASY way to build them as of today, Dec. 25th... no modification to their Portfiles (as of today) was necessary, either.

Run:

# port sync
# port clean --all python2x
# port patch python2x

Now, "cd" to the build directory... (and we'll patch every "isysroot" to "isystem")

# cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_python25/work/Python-2.5.2"
# find . -type f -print0 | xargs -0 sudo perl -pi -e 's/isysroot/isystem/g'
