codeblocks

问题 I'm rather confused about what my shaders are doing. I have a shader class which wraps the opengl parts of the shading for me. I build my application in code::blocks and run it, the compile fase fails, the linking stage fails but the verification with GL_VALIDATE_STATUS succeeds and the shader actually works. When I run it outside the codeblocks IDE the compile and linking stage succeeds and so does verification. When run in the IDE the ProgramLog and InfoLog are empty not even warnings but

问题 Is it possible to load a DLL with C and use its functions? I am new in C, and I am trying to search some good references on the internet for this; but I can't find any. Any help would be appreciated! I am using GNU GCC in Code::Blocks on Windows 7, 64 Bit. 回答1: HMODULE hModule = LoadLibrary(<dll file name>) followed by GetProcAddress(hModule, <function name>) will do this job using the WinAPI. An example could be found here. 回答2: I think you should investigate the LoadLibrary function. http:/

问题 Id like to know the process to link the Wincap library and use it in my c++ project im developing in Code Blocks. 回答1: After struggling to do this myself I figured that I should post my solution here. You will need to download the developer version of WinPCap and unzip it somewhere, lets say "C:\WpdPack_4_1_2". In Code::Blocks , you need to add the "Include" sub directory to the search directories. To do this, go to settings->compiler and click on the "Search directories" tab. For the

问题 What I would like to do is read the whole first line of the file but then after the first line only read the following lines until whitespace is hit. My end goal is to ask the user what line they want to edit by adding/subtracting time to said line. Sample File My test file 00:19.1 123456 00:35.4 testing whitespace end Desired Output 1: My test file 2: 00:19.1 3: 00:35.4 Code: #include <stdio.h> #include <stdlib.h> int main() { FILE *fptr1, *fptr2; char filechar[40]; char c[50]; int line

问题 I'm having some problems with Code::Blocks, and this is the output after / while compiling; 3|iostream: No such file or directory| 4|error: syntax error before "namespace"| |In function `main':| 8|error: `cout' undeclared (first use in this function)| 8|error: (Each undeclared identifier is reported only once| 8|error: for each function it appears in.)| ||=== Build finished: 5 errors, 1 warnings ===| My code is as follows; // my first program in C++ #include <iostream> using namespace std;

问题 I'm learning to use OpenCV (and C++) in Codeblocks. What confuses me, however, is that when I start to include header files from OpenCV in my main.cpp file, Codeblocks automatically suggests to me the files as shown in the image below. I have not included any search paths to project build options, so how is this possible that Codeblocks can find the files? Is there some other variable working here that I'm unaware of? Note that I'm a beginner with both Codeblocks and OpenCV and that I only

问题 I'm using code blocks with gnu gcc compiler. But when I try to compile a range base for startment it gives many errors. So I think the compiler dosn't support C++0x. So I want to know how to know the compiler version I'm using and how to update it correctly to a C++0x supporting one. I'm using Windows XP. 回答1: This algorithm may help to start with programming with C++11 on Windows: 1) Go to http://mingw.com and download the latest MinGW distribution, install it 2) Download the CodeBlocks

问题 While I am working in Vim I'd like to have a slight background color change for all code inside the php tags. So for example, the background is solid black for regular XHTML markup, then displays slighly lighter inside the php tags to help me identify it quickly. Is this something I can/should do with the color scheme or is there another method? 回答1: You can do it in the color scheme example: hi htmlTag guifg=#00bdec guibg=#200000 gui=bold 来源： https://stackoverflow.com/questions/900854

问题 I had 11 files that all need HDF5 library. Usually I just use another way to compile and built that program. Now I change my mind and I want to do it myself using Codeblocks. Here is the problem: I open the 'build option' in project in codeblocks. Then I directly jump to linker settings. And add the .a library files that needed. Then I just click 'rebuild workspace'. Here the error messages come out: gfortran -Jobj/Debug/ -Wall -g -O3 -c "/home/shawn/Documents/datafile_oldubuntu/Academics

问题 Yeah the question topic has been discussed so many times. And I'm almost clear about the difference. I've just one doubt related to an example in the book. This question is related to my previous question, where I presented 2 classes taken as example in the book C++ Primer. In reference to those classes, the book quotes the following paragraph, specially related to the declaration of member function of WindowManager class as friend function. Here's what it says: Making a member function a
