I downloaded the zip file Python for Windows extensions and extracted the contents into my Python27 folder. There's now a subfolder called pywin32-214. (Is the 32 part a problem? I'm on a 64-bit system.) Here's a transcript from the command line: C:\Python27\pywin32-214>setup.py -q install Building pywin32 2.7.214.0 Traceback (most recent call last): File "C:\Python27\pywin32-214\setup.py", line 2152, in ('', ('pywin32.pth',)), File "C:\Python27\lib\distutils\core.py", line 152, in setup

I see in the Apple sample code they use NSInteger (or NSUInteger ) when passing a value as an argument to a function or returning a value from a function. - ( NSInteger ) someFunc ;... - ( void ) someFuncWithInt :( NSInteger ) value ;... But within a function they're just using int to track a value for ( int i ; i < something ; i ++) ... int something ; something += somethingElseThatsAnInt ; ... I've read (been told) that NSInteger is a safe way to reference an

Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I tried to increase my virtual memory (page size) and RAM size, but to no avail. Can anyone tell me how can I eliminate this error? 回答1: Run the JVM with -XX:MaxHeapSize=512m (or any big number) (or -Xmx512m for short) 回答2: This can also be caused by setting something too large on a 32-bit HotSpot vm, for

It’s the processor architecture…a 32 bit machine can read and write 32bit data at a time same way with 64 bit machine…. whats the maximum memory that a 32 bit machine can access? It is 2^32=4Gb (4Gigabit = 0.5 GigaByte) That means 4Gb ram? If I consider the same way for a 64 bit machine then I can have a ram of 16ExbiBytes ..is that possible? Are my concepts right? 回答1: Yes, a 32-bit architecture is limited to addressing a maximum of 4 gigabytes of memory. Depending on the operating system, this

An example from here : struct { /* field 4 bits wide */ unsigned field1 :4; /* * unnamed 3 bit field * unnamed fields allow for padding */ unsigned :3; /* * one-bit field * can only be 0 or -1 in two's complement! */ signed field2 :1; /* align

On 14.04 I had a problem with gradle ( this one ), which was a problem with missing libz.so.1. Following this link , I had to install the 32-bit version of this package, and it fixed my problem. Now (I thought it was related), when trying to launch a device emulator, I have this message : ERROR: 32-bit Linux Android emulator binaries are DEPRECATED, to use them you will have to do at least one of the following: - Use the '-force-32bit'

I compile a simple Hello World program on one, and then I have figured out how to use gdb on one machine to remotely debug it running on the other machine. That seems to work fine when everyone defaults to 64 bitness. However, if I compile my Hello World with -m32 to generate a 32 bit binary, the way our full up system is being compiled, then I cannot figure out how to get gdb and gdbserver to correctly connect. Before I try it on our

I have a good knowledge of PHP but little knowledge about cryptography. I know the key and the iv of the crypted file. The file is decrypting fine as whole but the real issue arises when I try to decrypt the partial file from the middle. It decrypts fine when I try to decrypt the first 128kb of the file or 256kb or any length from the beginning of the file. but when I start from the middle, it does not

This seems to mesh with my experiences as we have an app that crashes when it reaches around 1.2 - 1.5 GB of RAM with out of memory exceptions, even though there is still plenty of memory available. My question is, would moving this 32bit app to 64bit windows allow it access more than the 1.5GB or so memory it can now? Or would the app itself have to
