[Pythonmac-SIG] Building a multi-component application with py2app
I have a wxPython application where the main process has a number of components that can be started as separate processes when required, for example, an independent GUI help viewer and several console-type helper tasks. With py2exe under MSW I can build them all into the same 'Dist' with a single setup.py so they share the same support modules and libraries. Is the same thing achievable with py2app? I can obviously build each component as a separate application, with no sharing, but the overhead is 10+ Mb per component. The py2app examples for drpython imply that the 'app' parameter in the call to setup can be a list of .pyw(?) files but when I try something similar, I get "error: Multiple targets not currently supported". Is it possible to achieve this, or maybe to 'merge' a number of standalone apps?

[Pythonmac-SIG] Py2app and shared libraries under Leopard
I've recently been involved with Robin Becker of Reportlabs building and testing one of their extension libraries across Intel and PPC hardware. Built using Distutils under Leopard, the library is working exactly as intended/expected. However, comparing the .so file produced, it is under half the size of the same built using Tiger - as well as having the execute permissions set, so Finder reports it as a Unix executable instead of a document. Both versions are reported as Mach-O universal binaries. $ cd /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/ $ ls -l _render* -rwxr-xr-x 1 forestfield admin 244620 10 Dec 12:40 _renderPM-Leopard.so -rw-r--r-- 1 forestfield admin 570732 10 Dec 16:38 _renderPM.so $ file _render* _renderPM-Leopard.so: Mach-O universal binary with 2 architectures _renderPM-Leopard.so (for architecture i386):Mach-O bundle i386 _renderPM-Leopard.so (for architecture ppc):Mach-O bundle ppc _renderPM.so: Mach-O universal binary with 2 architectures _renderPM.so (for architecture i386):Mach-O bundle i386 _renderPM.so (for architecture ppc):Mach-O bundle ppc The shared libraries in PIL also show the same effects when built under Leopard and Tiger respectively. When I apply py2app to an application that uses these libraries, when the Leopard-built versions are used, I get ValueError: Unknown load command: 27 as detailed in the attached log file. If I replace the libraries with their Tiger-built counterparts, the application builds OK (under Leopard). I installed Xcode on Leopard using default settings. Any ideas please?

Hi,

Everything is the same, except the wxPython version. Any ideas?
Paul
I recall getting an "Unknown load command" message from py2app after I
compiled the Reportlab extension *_renderPM.so* as a universal binary
under OS X 10.5 (Leopard) and tried to include it in the app. When I
compiled it again under 10.4 (Tiger), py2app (running under 10.5)
accepted it without any problem. I didn't (have time to) investigate any
further, only to note that the 10.5-built version was only 240 Kb
compared to 560Kb for the working, 10.4-built version.
Maybe there are extensions in wxPython 2.8.9.2 built using OS X 10.5
that were previously built using 10.4 and causing a similar problem?
Later
I have just rerun py2app with my original 10.5-built *_renderPM.so*
and -apart from me using a slightly earlier version of py2app than Paul
- it produces the self same error word for word (see attachments).
Could it be *_renderPM.so* itself that is causing your error Paul?

How about using
system_profiler SPUSBDataType
I treid the system_profiler and got the following results when I plugged
a couple of usb flash sticks in.
I couldn't see anything that resembles a unique usb storage device
serial number :( I think it is supposed to be a 12 digit (hex) number.
Either system_profiler doesn't report it, or these devices don't have
unique serial numbers (unlikely), or I am missing something (not unlikely).
Any thoughts ??
Strange, I just tried it here and got a serial number as usual (OS X
