compilation

问题 I would like to use an GNU LD version script to hide unwanted symbols in c++ shared library. Say my header file looks like this: int a(); int a(int); class B { B(){} ~B(){} int x(int); }; std::ostream& operator<< (std::ostream& out, const B& b ); I would like to hide everything which is not stated in the header file. How would a version script for this look like? 回答1: Something like this should do the trick: { global: extern "C++" { "a()"; "a(int)"; B::*; "operator<<(std::ostream&, B const&)"

问题 Okay, well supposedly PIL is supposed to be able to work with Tkinter automatically, but mine is not. I found this text file in the Imaging directories Tk directory. Using PIL With Tkinter Starting with 1.0 final (release candidate 2 and later, to be precise), PIL can attach itself to Tkinter in flight. As a result, you no longer need to rebuild the Tkinter extension to be able to use PIL. However, if you cannot get the this to work on your platform, you can do it in the old way: * Adding

问题 This question already has an answer here : ISO C++ forbids declaration of ‘multiset’ with no type (1 answer) Closed 4 years ago . I am trying to build a software using waf and I get the error: In file included from ../src/internet-stack/mp-tcp-typedefs.cc:6: ../src/internet-stack/mp-tcp-typedefs.h:151: error: ISO C++ forbids declaration of ‘multiset’ with no type ../src/internet-stack/mp-tcp-typedefs.h:151: error: expected ‘;’ before ‘<’ token ../src/internet-stack/mp-tcp-typedefs.cc: In

问题 I have a program I've written in c++ which outputs some simulation results to a .csv excel file. According to some instructions I need to create a simple bash script that would run the .cpp file given the command "$ run_program" ($ is not a part of the command). I've looked on Stackoverflow and other sites however I have not found a concrete answer to help me. I would also greatly appreciate it if those who answer can take some time to explain what the parameters mean. Thank you. How I should

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I have these files: classA.cpp , classA.h , classB.cpp , classB.h , and main.cpp . All needed libraries are included in both .h files. In main.cpp I include classA.cpp and classB.cpp . In classB.cpp I include classB.h and in classA.cpp it is classA.h I compile it by g++ main.cpp (

问题 I had this in my .cpp #include <iostream> #include <string> #include <vector> #include "HW00.h" using namespace std; int main() { string netId = "aag61"; HW00 hw00(netId); hw00.printMyAnswer(); return 0; } And I was able to compile the driver file into a .o file without any errors but when I run g++ -o HW00.exe aag61HW00.o HW00Imp.o I keep getting this confusing error: "ld: warning: ignoring file HW00Imp.o, file was built for unsupported file format ( 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00

问题 I am using Embarcaedro C++ Builder 2010 for a few weeks and there are somethings strage about the compilation process.. First, does anybody know a trick to prevent C++ Builder from re-compiling every source file that have'nt been edited ? Second, why is the compiler compiling more lines of code than the project really contains ? It awefully increases the compilation time ! I browsed the web without satifying answers. I tried : to keep object files to disable pre-compiled headers organising
