compilation

问题 Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . Improve this question I'm sure there's a way. I'm new to C and my research on this led me nowhere. Is there a command that can convert a .o file to .c? 回答1: Usually you can only determine the assembly language for the object file, using a disassembler . Here are a few links to

问题 I have a generated string that contains the code for an erlang module. Is there a way to compile the generated module straight from the string? Or is there a way to convert the string into the format needed for compile:forms/1 ? Or will I have to save it to a temp file first and then compile it with compile:file/1 ? Alternatively, I can add support to the compile module, but there must be a reason why the good people that write erlang haven't added it. 回答1: You need to scan your string into

问题 Before asking my question, I would like to cover some few technical details I want to make sure I've got correct: A Position Independent Executable (PIE) is a program that would be able to execute regardless of which memory address it is loaded into, right? ASLR (Address Space Layout Randomization) pretty much states that in order to keep addresses static, we would randomize them in some manner, I've read that specifically within Linux and Unix based systems, implementing ASLR is possible

问题 I have the following compiler error, how could I fix it? error: instantiated from `_Tp& std::map<_Key, _Tp, _Compare, _Alloc>::operator[](const _Key&) [with _Key = ar, _Tp = int, _Compare = std::less<ar>, _Alloc = std::allocator<std::pair<const ar, int> >]' This is the code: #include <map> #include <cstdio> #include <iostream> #include <algorithm> #include <cstdlib> using namespace std; class ar { public: int a; int b; int c; public: ar() : a(0), b(0), c(0) {} }; int main() { map<ar, int>

问题 I looked into eager compilation on numba's website and couldnt figure out, how to specify the types: The example they use is this: from numba import jit, int32 @jit(int32(int32, int32)) def f(x, y): # A somewhat trivial example return x + y # source: http://numba.pydata.org/numba-doc/latest/user/jit.html#eager-compilation as you can see it gets 2 variables as input and returns one single variable. all of them should be int32. One way to understand the decorator is that @jit(int32(int32, int32

问题 I have a CUDA project in a .cu file that I would like to compile to a .mex file using mexcuda . Because my code makes use of the 64-bit floating point atomic operation atomicAdd(double *, double) , which is only supposed for GPU devices of compute capability 6.0 or higher, I need to specify this as a flag when I am compiling. In my standard IDE, this works fine, but when compiling with mexcuda , this is not working as I would like. In this post on MathWorks, it was suggested to use the

问题 recently I moved my Matlab project from windows OS to Mac OS. so my jpeg_read.mexw64 file didn't work anymore and I needed to create a new mexmaci64 file that is compatible with Mac OS. I Downloaded JpegToolbox from here and then installed Libjpeg using: brew install libjpeg in Matlab I tried to use mex: >> mex -setup MEX configured to use 'Xcode with Clang' for C language compilation. To choose a different language, select one from the following: mex -setup C++ mex -setup FORTRAN MEX

问题 See below simple snippet: public class GenericsOverloadingDistinguish<T> { public void print1(T t) { System.out.println("t"); } public void print1(Integer i) { System.out.println("integer"); } } public static void main(String[] args) { new GenericsOverloadingDistinguish<Integer>().print1(new Integer(1)); } This would cause an ambiguous method call and will not compile. This is utterly confusing on the user of that class. It is not able to call neither print1(T t) nor print1(Integer i) simple
