The issue is that, in 32bits, an int (which is a 32bit integer) will hold a pointer value. When you move to 64bit, you can no longer store a pointer in an int – it isn’t large enough to hold a 64bit pointer. The intptr_t type is designed for this.
That depends on which variant of toolchain you’re currently using. Both DWARF and SEH variants (which come starting from GCC 4.8.0) are only single-target. You can see it yourself by inspecting the directory structure of their distributions, i.e. they contain only the libraries with either 64- or 32-bit addressing, but not both. On the other … Read more
There is no problems in running 32 bits executables on 64 bit OS (as long as 32 bit dynamic libraries are present and found). -m32 is there to compile 32 bits objects on a compiler configured to compile 64 bits objects by default.
You can find out a lot about the Python version you’re running via the platform module (the sys module also has a few simple helpers) On Mac OS X, you can run a “fat binary” with your chosen architecture with, for example, arch -i386 /usr/bin/python I do not recommend altering /usr/lib/python itself (with the lipo … Read more
For Python 2.6 and above, you can use sys.maxsize as documented here: import sys is_64bits = sys.maxsize > 2**32 UPDATE: I notice that I didn’t really answer the question posed. While the above test does accurately tell you whether the interpreter is running in a 32-bit or a 64-bit architecture, it doesn’t and can’t answer … Read more
Aapt is a 32bit application. I am running ubuntu 64bit. I needed some additional libraries. First thing I did was update to 13.04 from 12.10. It broke chrome but this should help. To get aapt working (this fixed my issues with the avd as well) just run these two commands: sudo apt-get install lib32stdc++6 sudo … Read more
SQLite contains unmanaged code, you can’t run it on a 64-bit operating system unless you deploy the 64-bit version. Quick fix: Project + Properties, Build tab, Platform Target = x86.
The only perf advantage to running IIS on 64bit vevrsus 32-bit is to allow access to a much larger memory address space. If you are doing normal ASPX page processing, then it’s likely you don’t need to address more than 4gb from any single process. Suppose you run in 32-bit mode with a web-garden with … Read more
Pyinstaller produces a binary depending from the python you used to build it. So if you use python 2.7 64 bit it is not possible, as far as I know, to produce a 32 bit executable. This is because Pyinstaller archives all modules and their dependencies (dlls, pyds etc..) which are 64 bit due to … Read more
The tumbleweed badge reminded me to come back and answer it myself! The way I got this to work was to use: setarch i386 ./config -m32
