compilation

问题 I'm trying to compile a Python 2.7 script that imports the following packages: import easygui as EG import numpy as np import pandas from skimage import data from skimage import measure import cv2 import matplotlib.pyplot as plt from matplotlib.widgets import Button import ntpath import os import time # Packages for progress bar import sys from PyQt4.QtGui import * from PyQt4.QtCore import * from PyQt4.QtCore import pyqtSlot,SIGNAL,SLOT easygui numpy pandas skimage opencv (cv2) matplotlib

问题 Let's say I have a code as such: import re docid_re = re.compile(r'<DOCID>([^>]+)</DOCID>') doctype_re = re.compile(r'<DOCTYPE SOURCE="[^"]+">([^>]+)</DOCTYPE>') datetime_re = re.compile(r'<DATETIME>([^>]+)</DATETIME>') I could also do this: >>> import re >>> docid_re = r'<DOCID>([^>]+)</DOCID>' >>> doctype_re = r'<DOCTYPE SOURCE="[^"]+">([^>]+)</DOCTYPE>' >>> datetime_re = r'<DATETIME>([^>]+)</DATETIME>' >>> docid_re, doctype_re, datetime_re = map(re.compile, [docid_re, doctype_re, datetime

问题 I was able to make a much simpler example than the one in my original post. I'm trying to compile a fortran code using gcc version 4.9.2 (x86_64-posix-seh-rev4, Built by MinGW-W64 project) on windows. Below is a batch script that I used to successfully compile the code: SET SRC_DIR=code gfortran -fopenmp -g -fimplicit-none -cpp ^ %SRC_DIR%/globals/current_precision.f90^ %SRC_DIR%/string/string.f90^ ... %SRC_DIR%/user/MOONS.f90^ parametricStudy.f90^ -o main.exe del *.mod The output looks like

问题 I want to start to write an os kernel, and then, i found a document introducing multboot2 spec. There are three example code files, named boot.S , kernel.c and multiboot2.h , belonging to the multiboot2 branch of grub project. Firstly, i tried to compile and link the code with some option (using i686-elf-gcc) such as -nostartfiles , -nodefaultlibs and -ffreestanding , but qemu showed me the format was error. And then i found a file named Makefile.am , and the compiler option in this file is

问题 If I try to compile the below with the iOS4 sdk version of gcc. It gives me the error: Conversion from 'const char[4]' to non-scalar type 'UsesStr' requested class strptr { public: strptr(const char * s) : s_(s) {} const char *c_str() const { return(s_); } protected: const char *s_; }; class UsesStr { public: UsesStr(const strptr &sp) : p_(sp.c_str()) { } const char *p_; }; static UsesStr ustr = "xxx"; This is a simple case, it is a problem is when strptr is a string class that is used

问题 When we use javac option: -source and -target how does the compiler "knows" the code to produce ? I mean how does any compiler knows the specification of any previous java release or I have to do some setting in order to provide it with some information about them ? 回答1: The javac program knows how to handle these arguments without you providing any extra information. Do note that there is a bit of a trap here, however: these options relate to the source syntax and the class file form and
