问题 This is useful for debugging (hence programming related). On linux, we can use the command strace -feopen python myfile.py to figure out which python modules and shared objects are loaded. Is there an equivalent one-liner on macOS X? 回答1: I suppose you meant strace -fetrace=open ? dtruss -f -t open python myfile.py 来源： https://stackoverflow.com/questions/1925978/equivalent-of-strace-feopen-command-on-mac-os-x

问题 Is it possible to install clang 3.1 on xcode 4.2 (Snow Leopard)? 回答1: You can also build and install it yourself. Instructions can be found here. I'm not sure if this (or the MacPorts solution... +1 to @trojanfoe) will easily be callable from Xcode though. After moving everything from " /Developer " into & within the Xcode package, I'm thinking Apple is trying to keep Xcode a "walled garden" as well. 回答2: Yes, try the macports version. You can also download the binaries, if you can't be

问题 I'm trying to strip my mac os x application of all unneeded symbols. If I do this on my linux app using "--strip-unneeded" the symbol table on my application is empty and returns nothing. On Mac OS X, I am seeing symbols related to the typeinfo and vtable entries for my classes, as well as some function. As best as I can tell, this is happening on the functions defined in headers and marked inline. Undefined functions coming from external libraries are present in the nm output, but marked

问题 I recently learned Python (2.7) and have been making some simple board games with AIs and such as practice. I am currently making an intelligent hangman game which necessitates the inclusion of a dictionary file. (I have a text file which has a new word on each line). I used py2app successfully for other stuff such as this: connect-four.zzl.org but unfortunately, it doesn't seem to include my text file when I run py2app for my new hangman program. Can anyone help me figure out how to include

问题 I am trying to build a JVMTI agent using the g++ command on Snow Leopard and I get the following error: $ g++ -o agent.so -I `/usr/libexec/java_home`/include agent.cpp Undefined symbols: "_main", referenced from: start in crt1.10.6.o ld: symbol(s) not found collect2: ld returned 1 exit status I am a total novice when it comes to gcc and C++ programming so I have no idea what that error means.

问题 I just installed Ruby Version Manager (RVM) which is working fine but it asked me to put the following line in my /.bash_profile and ~/.bashrc files: if [[ -s /Users/tammam56/.rvm/scripts/rvm ]] ; then source /Users/tammam56/.rvm/scripts/rvm ; fi looking at the content I see the following: tammam56$ cat /.bash_profile export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" if [[ -s /Users/tammam56/.rvm/scripts/rvm ]] ; then source /Users/tammam56/.rvm/scripts/rvm ; fi tammam56

问题 I just upgraded to Mac OSX Snow Leopard, and recompiled mysql (5.1.39) with the Snow Leopard XCode. I also reinstalled the latest mysql gem.

问题 I have XCode 4.2 and need to submit a Mac app to App Store. I've tried all kinds of suggested methods to get the multi-resolution icons in there, so you don't need to inform me on that. The remaining method is to use iconutil . I've searched in Spotlight, searched my Mac's harddisk in Finder, two later XCode .dmg images, sudo find in Terminal, and looked for paths on the web. The XCode 4.4.1 .dmg had Iconutil.strings and Iconutil.xcspecs , but that's as far as I've come. Is there a package I
