Program "g++ not found in path" in Eclipse Juno CDT in Ubuntu
Eclipse 6月的CDT报告g++ not found in path ，如何解决这个问题？
Typically, g++ will be installed when gcc (GNU Compiler Collection) is installed. First confirm that you have g++ installed.
You can check this by typing the following in a terminal: which g++. The response ought to be /usr/bin/g++.
If you find g++ installed, in eclipse go to project->properties->C/C++ Build->Discovery Options, under tools GCC C++ Compiler, put the exact path to g++ instead of g++ (if g++ alone does not work).
You will find this link useful: What is the difference between g++ and gcc?
If you still have problems, do get back with feedback.
I had similar problem and it is solved by
Installing g++ The GNU C++ complier using ubuntu software centre and
Changing in -
Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build in Complier Settings [Shared]
From: ${COMMAND} -E -P -v -dD "${INPUTS}"
To: /usr/bin/${COMMAND} -E -P -v -dD "${INPUTS}"
I hope it helps. I think if you add it to the project as mentioned in the first answer, you will need to add all the time for new projects. And if you add as I wrote you don't need to add it for new projects.
I have exactly the same problem. I never had problems with eclipse before under linux and now it wont even compile code. I tried to change the name of the g++ and gcc compilers to their exact location in project->properties->c/c++ Build->discovery options etc. nothing helped, I tried to reinstall eclipse and did an initialize, added the path to the variables etc.. Nothing worked so fare. The project I am working on is quiet big and I rather would like eclipse to manage the source and makefile, instead of doing it manually
Linux Mint 15 Eclispe: Version: 3.8.1 (I tried it with the latest version as well ... nothing changed)

example:
#include // not resolved using namespace std;
int main() {
std::cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
return 0;
}
Well the code above is not what bothers me, as I can fix it by adding the includes of the exact c++ include path, but the code just wont compile. Wired enough eclipse gives me the error:
Description Resource Path Location Type Program "g++" not found in PATH Preferences, C++/Build/Settings/Discovery, [CDT GCC Builtin Compiler Settings] options C/C++ Scanner Discovery Problem
but it appears to me to be possible to compile single files, by opening them and pressing crt+b, but the whole project wont compile.
Fixed the problem this morning:
- got the latest eclipse
- created a new workspace
- created a new project
after a few seconds the very same error disappears
