I was attempting to get matplotlib, the python plotting library, installed via macports and the first problem is that the library is dependent on odcctools (20061117_0), which fails to build in the x86_64 environment.

But, we can get it to build…:

1) (clean the slate)

$sudo port -v selfupdate;sudo portindex
$sudo port clean –all odcctools

2) (this part will fail)

$sudo port install odcctools

Output:

—> Fetching odcctools
—> Verifying checksum(s) for odcctools
—> Extracting odcctools
—> Configuring odcctools
—> Building odcctools with target default
Error: Target org.macports.build returned: shell command ” cd “/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_odcctools/work/odcctools/odcctools” && make default ” returned error 2

3)
(hint from http://code.google.com/p/iphone-dev/issues/detail?id=106#c1 )
From this path,
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_odcctools/work/odcctools/odcctools
in each subdirectory, look for a “Makefile”. IF the file has a “MYINCLUDES” line, add this after the equals ( = ) sign:
“-isysroot /Developer/SDKs/MacOSX10.4u.sdk” (w/o quotes). If the Makefile doesn’t contain a line which starts with MYINCLUDES, then ignore it.

e.g. This is how the line will look after putting in:
…
MYINCLUDES = -isysroot /Developer/SDKs/MacOSX10.4u.sdk -I$(builddir) -I$(srcdir) -I$(top_builddir)/include \
-I$(top_srcdir)/include $(INCPRIVEXT) $(FORHDRS)
…

4) (continue installation)

$sudo port install odcctools

Output:

—> Building odcctools with target default
—> Staging odcctools into destroot
—> Installing odcctools 20061117_0
—> Activating odcctools 20061117_0
—> Cleaning odcctools

Done.

Next, I tried to continue the installation of matplotlib (e.g. sudo port install py25-matplotlib ), but <sigh> now g95 won’t compile…

[UPDATE 22 Sat, 2007: py25-matplotlib, including g25 now installs via Macports!!]

Yes, the world is treated to yet another blog.  I have wanted to have a blog for some time now, to share, give back if you will, things I have learned – some internet wisdom and some of my own discoveries.  I spent some time looking at CMS software and wanted to do something based in Python since I’m learning it, but since my web provider (1and1.com) only supports version 2.2.1 (yes, a version over 4 years old, and yes I asked for a newer version but was shot down), I decided instead on the ubiquitous WordPress.

I’m an oceanographer in California, where I use Matlab and build websites, so will hopefully pass on nuggets of wisdom regarding Matlab, Javascript, PHP and CSS. I’m also a recent and enthusiastic Mac OS X convert, but dabble in Linux (Fedora) and am a Windows power user, so these subjects may come up. I’m also learning python and planning on taking some of the O’Reilly on-line classes, so will probably post some things about them too.

Oh, and “newsyland” is, I hope, a witty homophone to New Zealand – a place I’d love to live some day…
