compilation

问题 I'm trying to build multiple versions of python using Pythonbrew, but I'm getting some test failures. This is on a VM running: Ubuntu 8.04 32bit This happens when I use the --enable-shared option The build.log file errors are shown below: Python 3.2 Here are the failed tests for Python 3.2: LD_LIBRARY_PATH=/opt/standingcloud/stack/pythonbrew/build/Python-3.2: ./python -E -c 'import sys ; from sysconfig import get_platform ; print(get_platform()+"-"+sys.version[0:3])' >platform find ./Lib

问题 I have a project that I want to cross-compile for Windows. I have the appropriate Makefile and everything works with g++ . I've run $ apt install mingw-w64 and downloaded 500 MB of packages, but I cannot find out how to actually run it. There is no mingw executable, so how do I actually compile with it? 回答1: If you look at the file lists on the Ubuntu package webserver for mingw-w64 's constituent packages: gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 binutils-mingw-w64-x86-64 mingw-w64-x86-64

问题 I am coding in Eclipse and have something like the following: #include <ftream> #include <iostream> void read_file(){ char buffer[1025]; std::istringstream iss(buffer); } However, when I try to build, I get the following error: variable 'std::istringstream iss' has initializer but incomplete type Any quick thoughts? I have googled around and it seems like most people with this problem simply did not include the right header files which I believe I am doing correctly. 回答1: You need this

问题 This question already has an answer here : Closed 10 years ago . Possible Duplicate: What IDE to use for Python I have Notepad++ and NetBeans 6.8, however I don't know if they work. I know you can edit Python with Notepad++ and compile/run it using the command line thing, but I'm not really sure how. I know NetBeans is a full-featured IDE and you can compile Java programs, but I don't think they support Python? Any ideas? 回答1: Eclipse with PyDev has been a great combination for me. Great

问题 This was an interview question. I said they were the same, but this was adjudged an incorrect response. From the assembler point of view, is there any imaginable difference? I have compiled two short C programs using default gcc optimization and -S to see the assembler output, and they are the same. 回答1: The interviewer may have wanted an answer something like this: i=i+1 will have to load the value of i , add one to it, and then store the result back to i . In contrast, ++i may simply

问题 I have a directory structure where I want one main makefile in my main folder, and then another makefile in both my test and src folder. In my main makefile, I have directives for both test / all that call the individual folder makefiles. I'm trying to declare variables in my main makefile and have them accessible to those other folders. For instance in my main Makefile PACKAGES = jansson mysql .... all: do something here test: cd test make test And then in my test/Makefile I want to be able

问题 I'm developing a C++ project which is going to be enclosed on a bigger one. I've seen that on the bigger project (is a Qt application and it's being generated from qmake) I am able to compile a single file from the linux command line, just entering the relative path to the specific file as an argument to make. On the other hand, I'm using CMake for my own project. When I modify some code for a compilation unit and I have to modify its header file, I have to wait a long time to compile its

问题 From what I understand, instructions and data in an object file all have addresses. First data item start at address 0 and first instruction also start at address 0. The relocation table contains information about instructions that need to be updated if the addresses in the file change, for example if the file is linked together with another. Line A, in the example below, would be in the relocation table. I don't think B would be in the relocation table, since the address of label "equal" is
