OS X Python: can I explicitly set MACOSX_DEPLOYMENT_TARGET for extensions?
by Andrew Jaffe Oct. 27, 2015

Oct. 27, 2015

[Also posted to general python list...] I use the python.org framework build of Python under recent versions of OS X (i.e., 10.11 El Capitan). I need to build some extensions that rely on recent versions of compilers (e.g., C++-11 features). However the python.org python is built to work on older systems as well, for backward compatibility. Hence, it has the environment variable MACOSX_DEPLOYMENT_TARGET=10.6. This means that extensions are built by default with a toolchain that, I think, mimics gcc-4.2, in particular in terms of what stdlib it searches. In the past, I have fixed this by installing more recent compilers with homebrew and explicitly setting CC, CXX, etc before installation. However, I have tried just setting MACOSX_DEPLOYMENT_TARGET=10.11, and that seems to work. Is this safe? Are there any downsides? (I don't need to distribute these builds, just use them locally?) Conversely, are there any upsides? Does a newer deployment target allow more recent compilers and/or higher optimizations? -Andrew

PyobjC using pdb on yosemite
by Karsten Wolf Aug. 26, 2015

Aug. 26, 2015

I am setting up a 10.10 system and the current annoyance is that when pdb.set_trace() stepping through a pyobjc/py2app app everything printed, event the (pdb) prompt is piped through NSLog and hard to use. The Python version is 2.7.10 and compiled with X86_64 and MIN_DEPLOYMENT_TARGET=10.6 Perhaps someone knows a remedy.

I have no idea what codesign_allocate is or why I need it. I'm not using codesing_allocate directly. if the CODESIGN_ALLOCATE env var is not set, then codesign complains about not being able to find or use the helper tool. dist/<myapp>.app/Contents/Frameworks/libncursesw.5.dylib: the codesign_allocate helper tool cannot be found or used Is this not normal? Maybe there is something screwy with my OS X system or Xcode install? Interestingly, the man page for codesign does not menthod the --signature-size option, but codesign doesn't complain about it.

Yes that was my bad. startssl.com is correct.

codesigning py2app/wxPython app failing
by Brendan Simon (eTRIX) Aug. 23, 2015

Aug. 23, 2015

I'm trying to codesign a wxPython app bundle generated with py2app. (python2.7, wxPython 3.0.2, Intel 64/32-bit, build on 10.10.5, XCode 6.4 installed) I'm getting the following error: $ codesign -vvvv -f --deep -s <mycredentials>dist/<myapp>.app dist/<myapp>.app: code failed to satisfy specified code requirement(s) In subcomponent: <path>/dist/<myapp>.app/Contents/Frameworks/libncursesw.5.dylib I've read that this can be a problem if a framework is signed, but it isn't. Also "codesign -f" is supposed to replace any signed objects anyway, right? $ codesign -vvvv dist/<myapp>.app/Contents/Frameworks/libncursesw.5.dylib dist/<myapp>.app/Contents/Frameworks/libncursesw.5.dylib: code object is not signed at all In architecture: x86_64 For testing, I removed libncursesw.5.lib, but now codesign complains about dist/<myapp>.app/Contents/Frameworks/libwx_osx_cocoau-3.0.0.2.0.dylib. If I remove libwx_osx_cocoau-3.0.0.2.0.dylib, it complains about dist/<myapp>.app/Contents/Frameworks/Python.framework. If I remove Python.framework, it complains about dist/<myapp>.app/Contents/MacOS/python If I remove python, I don't get any errors referencing any files or directories, but I still get the "code failed to satisyfy specified code requirement(s)". $ codesign -vvvv -f --deep -s "Sureshot" dist/<myapp>.app dist/<myapp>.app: code failed to satisfy specified code requirement(s) I set up the following environment variable to resolve a codesign_allocate error. There were other codesign_allocate binaries on my system but this is the only one that seemed to not complain. export CODESIGN_ALLOCATE="/usr/bin/codesign_allocate" Any ideas about what is going on and how to resolve this? Is it a certificate issue perhaps? I purchased a class2 cert from sslstart.com. I was a renewed one and I'm not 100% sure I'm using the correct private key for the certificate. Would that cause the above errors? I've never had any success signing an app. I get the same errors with another cert/private key that someone else provided to me (from www.digicert.com). KeyChain says that both certs were signed by an unknown authority. Could this be the issue? Thanks for any help. Brendan.

Not really, the work that needs to be done is IMHO only partially related to the PSF mission. Apart from that I think I’d should try to raise some funding from the community before talking to the PSF, at the very least that would show that it wouldn’t be a complete waste of funds. Before I can do any of that I’d have to get a clearer picture of what I’d like to do, and (more importantly) how to accomplish that.

But are you saying that you could put time into it if you could get paid? Maybe kick starter? thought this: http://blog.felixbreuer.net/2013/04/24/crowdfunding-for-open-source.html indicates that it doesn't work well for Open source projects. Are you set up with a consultancy so that people could pay you for a particular bug fix or feature? For example, the US federal government (which I work for) can not donate to anything. We can, however, pay a contractor to provide a particular service. As an example, we are right now wrestling with PY2App to distribute a product. If we could have hired you to get that all set up for us, then you may have been able to get a few bugs fixed, while we could have gotten what we needed to economically. NOTE: it's too late now, and It might have been difficult for us to contract with a non-US entity, but you get the idea. As a matter of fact, we did something much like this with Robin Dunn, the wxPython developer -- we hired him to extend an app of ours that required some updating/improving of wxPython. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

That’s my perception as well. A site like kickstarter also appears to require you to work on a specific product (a gadget, new software, …) and not ongoing development of an existing project.
