macports erlang build disables smp by default
by Fred Dushin 03 Mar '08

03 Mar '08

I thought I'd mention this to any macerlangers out there. Discovered this testing some concurrency code, and saw the following in the erlang Portfile: configure.args --prefix=${destroot}${prefix} \ --enable-threads \ --enable-kernel-poll \ --enable-hipe \ --disable-smp-support There is an smp variant, though, which you can use to enable smp support. I wonder if we should make this the default, no? Are there some known bugs in the smp code? (I know /my/ code runs 2wice as fast with it on... :) -Fred

unixODBC and postgresql83 are incompatible
by Chris Waterson 03 Mar '08

03 Mar '08

It turns out that postgresql83 can't be installed with unixODBC present, since unixODBC has a file called "sqltypes.h". It seems like the postgresql83 build ought to be fixed to ensure that it looks in build-local directories for include files before looking in /opt/ local/include. (Sorry to be lazy, and not provide a patch -- since I'm not using unixODBC, I just uninstalled it and postgresql83 built fine.) chris

Re: rsync refusal in MacPorts 1.6.0 install: still busted.

We definitely want to make MacPorts easier to use. I'm sending this to the macports-users mailing list also so that people see again that it's still a problem in 1.6.0. I don't remember if this has already been fixed in trunk. Our release manager has been busy with other things which is why there hasn't been a new MacPorts release in awhile, though we already have many new things in trunk that should be released.

General Leopard Installation Recommendations - with Admin? Postgres, Postgis...
by Stefan Schwarzer 03 Mar '08

03 Mar '08

Hi there, I am using a Mac in the office for website development, database administration, design etc... Now, as I am not coming from an admin-, but more from a casual-user- side, I did run into some admin/su/etc.-problems or challenges when installing & compiling postgres, postgis, etc. So, I was wondering what you guys do recommend. In the moment, I am the only user and the only admin on the same time on the mac. But, from a admin/security perspective, there should be already a different account for me as a user and another one for the admin, no? And on the next step, there should be another one for the postgres administration, no? Can you give me a recommendation how to "better" (more efficient, more correct, not necessarily more "safe") setup my computer? Thanks for any advice, Stef ____________________________________________________________________ Lean Back and Relax - Enjoy some Nature Photography http://photoblog.la-famille-schwarzer.de Appetite for Global Data?

Port Verification
by Michael Franz 02 Mar '08

02 Mar '08

I am trying to verify the xorg-libXt port. It seems that xorg-libXdmcp has now become dependant on xorg-xproto. I checked the history of the xorg-libXdmcp Portfile, and it hasn't been changed in 6 months. So, the Portfile hasn't changed since I started. I did my original testing less than 2 months ago. The only thing that I can think of that is different is I may have tested on an updated version of OS X 10.4.11. I am currently running a base install of OS X 10.4.6 without running update. Is there an easy way to validate ports? The way I have been doing it is very labor intensive (uninstall macports, remove all ports, re-install macports, test port). It would be nice if there was a way to run in a chroot environment for development testing of ports. Michael

matplotlib: no interactive backends appear to work
by John Owens 01 Mar '08

01 Mar '08

In macports, matplotlib is not working quite like I'd like. I've installed it for both python24 and python25. It appears the dependencies aren't quite right (sufficient) so I have manually installed a few packages besides the normal dependencies; this bears further investigation but I'd have to uninstall a bunch of things to properly test it out so I'll leave that alone for now. Anyway: I'd like this package to work with the large variety of backends that matplotlib supports, so I am going through them now to point out issues with the current install. This is the current MacPorts (1.6) with 10.5.1 on Intel (MacBook Pro) and the latest portfiles. Summary: No interactive backends work at all. I'm not asking for every backend to work, but at least some of them would be nice. I'd think about prioritizing TkAgg and making sure that pdf in 2.5 also works. First, I've installed both python24 and python25: $ port installed | grep matplotlib py-matplotlib @0.90.1_0+numpy+tkinter (active) py25-matplotlib @0.90.1_1+numpy+tkinter (active) I can configure the backend by setting it in ~/.matplotlib/matplotlibrc. That is the only setting I have in this file, so everything else is default. I am testing this with 'test.py', the simplest possible matplotlib program: from pylab import * plot([1,2,3,4]) show() # for interactive, or savefig('test') for file and running with python2.4 test.py (or python2.5 test.py). OK, let's start looking at backends. First, the file-saving backends, then the interactive ones. ++++++++ backend: Pdf ++++++++ 2.4: Writes pdf correctly (woo hoo!). 2.5: Fails with AttributeError: 'module' object has no attribute 'decoding_map' $ python2.5 test.py Traceback (most recent call last): File "test.py", line 4, in <module> savefig('test') File "/opt/local/lib/python2.5/site-packages/matplotlib/pylab.py", line 796, in savefig return fig.savefig(*args, **kwargs) File "/opt/local/lib/python2.5/site-packages/matplotlib/figure.py", line 759, in savefig self.canvas.print_figure(*args, **kwargs) File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_pdf.py", line 1395, in print_figure file.close() File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_pdf.py", line 401, in close self.writeFonts() File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_pdf.py", line 456, in writeFonts fontdictObject = self.embedTTF(filename) File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_pdf.py", line 508, in embedTTF widths = [ get_char_width(charcode) for charcode in range(firstchar, lastchar+1) ] File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_pdf.py", line 505, in get_char_width unicode = cp1252.decoding_map[charcode] or 0 AttributeError: 'module' object has no attribute 'decoding_map' ++++++++ backend: Ps ++++++++ Appears to write both ps and eps correctly for both 2.4 and 2.5. ++++++++ backend: Svg ++++++++ Appears to write svg correctly for both 2.4 and 2.5 (openable in Firefox).

py25-* package building on Leopard
by Brian Barnes 01 Mar '08

01 Mar '08

Hello, I have recently successfully installed py25-pyx (with texlive), py25- zlib, and py25-tkinter on Intel Leopard with macports 1.6.0. There is an outstanding trac ticket regarding py25-zlib: http://trac.macports.org/projects/macports/ticket/13406 In the ticket, an initial build failure is solved by either retrying the 'port install' command for py25-zlib, or examining the error message, going into the indicated directory, executing the desired command (also from the error message), leaving that directory and retrying the 'port install' command. I would like to mention that today, I experienced that identical error with a different package, py25-tkinter. The solution was exactly the same, too. I thought it was curious enough to have the same kind of install error with two different python 2.5 packages that I'd mention it on the list, so that anyone else affected by this (perhaps with other packages) is aware of the simple workaround. Macports on Leopard is working great. Apple would be wise to promote this on their website, or throw some serious money behind it (if they haven't already)! Thanks, maintainers. Brian

gnome
by Richard Sara 01 Mar '08

01 Mar '08

I have installed the Gnome desktop mega port and thought I followed the installation instructions corrects, but obviously not. I have somehow got myself into an infinite loop at the GDM login screen, which sits on top of all other windows and, regardless of what user name/password combination I use refuses to all login. I have trawled through the pages I can find on this site, but I can't sort it out (which is not saying an answer is not here, I just don't know what I am looking for). The GDM logon dialogue opens regardless of the user (admin/richard) so I have been looking in /Library, /Library/ LaunchDaemons and /Users/(username)/Library, /Users/(username)/ Library/LaunchDaemons but no luck. I can't find an /.xinitrc file for any users. All help gratefully accepted and acknowledged.
