问题 Glade files and the program files can get a bit messy, this becomes a problem when you want your program to be portable. Is there any way to bind your program with your glade files? Source code (unfinished but working project): https://github.com/caelwithcats/valuator 回答1: You can use Gio Resources to include the contents of your .glade files in the application, and then use GtkBuilder's add_from_resource() to load them: https://developer.gnome.org/gtkmm-tutorial/stable/sec-gio-resource.html

Improve this question I am trying to run this code and it says segmentation fault when I run it. It compiles good. Here is the code. (It works fine on windows). #include<iostream> #include<vector> #include<immintrin.h> const int size = 1000000; std::vector<float>A(size); std::vector<float>B(size); std

问题 I was going through the source of some of the standard headers included with gcc (in /usr/include/c++/ ) and found the following at the top of every header: namespace std _GLIBCXX_VISIBILITY(default) What exactly is _GLIBCXX_VISIBILITY(default) ? 回答1: It's a preprocessor macro. And is defined as: #if _GLIBCXX_HAVE_ATTRIBUTE_VISIBILITY #define _GLIBCXX_VISIBILITY(V) __attribute__ ((__visibility__ (#V))) #else #define _GLIBCXX_VISIBILITY(V) #endif So if _GLIBCXX_HAVE_ATTRIBUTE_VISIBILITY is

问题 In c++20, when enabling modules, each include is supposed to be encapsulated so that the ordering does not matter, and macros does not leak out etc. Apparently the question if it is possible to precompile multiple headers is yes. My question now is: How do you do this: That is: How do i first precompile a set of headers and then make the compiler recognize them (all of them) as precompiled headers for my translation unit using c++20 modules, (using linux command line). I would like to have

问题 I've just started using g++, downloading the latest version from the site, and I've made a simple HelloWorld program. #include <iostream> using namespace std; int main() { cout << "Hello World!" << endl; return 0; } When I try to execute using the powershell window and g++, in the right directory, I use the following command: g++ HelloWorld.cpp -o HelloWorld.exe This gives no output and makes no files. I used the -v command as per some other answer I read on the site and it gave me this. I

问题 In a related question (" std::string formatting like sprintf ") I learned about this awesome new C++20 header <format>. However, there seems to be no supporting compiler. Is this correct or is there a way to use it anyway? I'm using g++ 9.3 with the -std=c++2a flag and the library <format> is not recognised. #include <format> // fatal error: format: No such file or directory #include <iostream> int main(){ std::cout << std::format("Hello {}!", "World"); } g++-9 test.cpp -o test -std=c++2a 回答1
