I'm new to using Eclipse. I'm trying to write some C++ code in it with the CDT but I can't figure out how to tell it to rebuild manually. I did a little test program and accidentally put SDL_EVERYTHING instead of SDL_INIT_EVERYTHING in SDL_Init args. I changed it to the correct name and saved but when I right clicked on the project and chose run as c++ application it said I still had that error. In fact that line is still underlined in red saying it can't find SDL_EVERYTHING even though it's been changed.
Does anyone know how to force eclipse to rebuild or how to clear these errors? This seems trivial but I haven't found anything online about how to get around it.
I don't have CDT installed on this computer at the moment, but as I recall you can clean and build a project using options under the project menu.

I installed CodeLite and was rightfully put in the direction to install MinGW. I installed MinGW right from where CodeLite suggests/links to it and everything went well there. I then click "scan" on CodeLite to find the just installed compiler and it says it can't find any on the system -- lost already here.
I then just tried to configure the directory of the compiler to one which is provided with MinGW, such as gcc. I try to compile any basic hello world or such and get the error that, "The system cannot find the file path specified." When trying by default it would compile even before actually properly setting up the compiler, so it seems completely backwards on the face of it. Maybe it's some cross/directory issue?
The log shows CMD.exe looking to cd to some weird/incorrect directory. I've changed environment variables to only include MinGW's path and the issue persists. I've changed around global settings/include paths/build settings to point to the compiler, but it just won't get past this.
Aside from manual setup not working and CodeLite being unable to find MinGW despite it being 100% verified and installed properly, I am basically lost here.
I have prior programming experience, but usually with everything out of the box. I'm now trying to get back in but wanted to learn the process of setting up a compiler/getting more "hands on."
I'm pretty sure it's something set up wrong by me, but the problem is clearly that I have no idea what.
CodeLite does not need the compiler to be in the path. You can "tell" CodeLite where it is installed by pointing it to the right folder from Settings->Build Settings
See this wiki page, note that the build settings dialog is a bit outdated, the drop down button does not exist anymore, instead you have a toolbar with green + button, click it instead.
Once you added the compiler, right click on your project and and select Project Settings, under the General tab, choose the compiler you just configured.
I had the same issue where I had MinGW installed and working, then I downloaded CodeLite and went into the setup wizard, where it could not find MinGW.
Essentially the fix I found was closing and re-opening CodeLite.
I saw on the CodeLite site that the compiler should not be in a folder path with spaces in it, so I moved my compiler from "Program Files" to "ProgramFiles" and manually pointed to it using Settings -> Build Settings. However, CodeLite's scan still couldn't find it until I restarted it.
Then I moved my compiler back to its original folder and restarted CodeLite again, it worked.
I installed NeatBeans IDE 8.1 fresh for C++ development and began a blank new project. The code for the project is shown below. The code within the editor shows a syntax error, although when building, THE CODE RUNS PERFECTLY FINE.
Although iostream is imported correctly, and I can view iostream.h by clicking on it, std seems to be completely undefined. In fact, I cannot use any library without it showing a syntax error. I realize that having an std in front of cout is redundant, since I am supposed to be using namespace std, but I just wanted to show that it is not just the namespace. I am using a 64 bit MinGW compiler as my configuration as pictured below.
I have tried using all solutions online, such as Reparse project, but that and others do not seem to help rectify this issue. How can I make the editor show no syntax errors and build correctly?
I remember having this problem. I used to fix it by doing a "Run -> clean and build project".
Okay so basically I'm working on recursion. And I recently switched from a mac to a PC, so I'm now using eclipse instead of XCode for programming c++. now this has happened to me a couple times, and I still have no idea why its doing it. When this happens I do not get an error code, I've searched far and wide for this solution but haven't found one yet, so i'm hoping you guys could help. So everything was going great (almost finished), but i realized a bug, so I fix it, then I save it, then I build it, run it, then it doesn't build properly (i'm assuming), like it didn't build my new code, it just rebuilt my old code and ran that, im using MinGW, I've also tried to import my old code via copy and paste, but it did the same thing, please help.
*let me know if I left anything out that might be needed to know
**update on my project file it does have a error sign on it, but there isn't one in my code
***update update I looked through the errors and found that it doesnt have permission to open output file "recursive.exe" (my project name)
OK solution: run eclipse as admin
I have been trying out using Eclipse CDT for a course I am taking. Previously I have been using Visual Studio Express but since that requires me to be online and I have to use the IDE+compiler offline, I switched to Eclipse + Cygwin GCC.
Now everything was working prefectly, until I got an error about file paths in my make file. After reading some of the posts online, the issue seemed to be that Cygwin's make does not resolve absolute Windows file paths because of the ':' symbol and confuses it with a new target definition. The proposed fix was to download a fixed make file. I diligently did so and the programs would compile fine.
But after I went into the first debug session, everything froze. I aborted eclipse and tried a clean build but now the compilation wont happen AT ALL, which is very weird for me.
I can't find a post for a similar problem so I am really stuck now. I was currently working the assumption that my CDT may be corrupt or something so I downloaded Eclipse Luna just today and tried building using that, but no joy. Even a fresh project in a new workspace wont compile.
Appreciate the help in advance.
Did you try redownloading Eclipse? Sometimes Eclipse gets a fatal error glitch that makes it unable to compile anything. I've had this problem before, the only way i was able to fix it was to uninstall and re download the latest version. If this doesnt work, try switching to Bloodshed Dev C++ or codeblocks.
So it seems like an issue with the new make (v3.80). upgating it to v4.08 fixed the issue of not building.
Version 4.08 however does not fix the Windows file paths not being recognized properly and treated as a target definition. I am still getting the multiple target patterns. stop error.
EDIT: Found this on Stack overflow to solve the issue... should have searched better previously.
Very simple application fails with "multiple target patterns" from Eclipse
When programming in eclipse (c++), I would like to just hit f5 (run) and have the project I'm working on save, build and (if there are no errors) run. If there are errors I want it to show the problems window and stop.
This all works at the moment except for the part where it shouldn't run when there are errors.
Is there a way to make eclipse never run the project when there are errors? Perhaps with an addon?
EDIT: Forgot to mention the prompt... The prompt does show but I want it to not show at all. If you look at the preference window you'll see that there's no 'never' option, there is one for all the other options but not for the 'launch if project contains errors'.
By default, Eclipse CDT does not run code with build errors, but maybe you have checked the option Always launch without asking checkbox.
You should go to Windows menu->Preferences->Run/Debug->Launching->Continue launch if project contains errors and check Prompt option instead of Always. Using this, Eclipse CDT will prompt you if errors exists during building or launch your binary if it has been compiled without errors.
