If you post more info people are morelikely to find the cause of the error. what does the compiler say before this error is given?

[Altera_Forum]

thanks ROBINKERSTENS92 for your response..im not very sure your mean about the 'what does the compiler say before this error'..but when im try to run it,  

this statement was popup 'the selection cannot be launched,and there are no recent launches'..ermmm

a quick google search should solve the issue you're having at the moment. 

 If you can post the text you see in the "console" tab, that is the build log of your current project. it will show the places where eclipse is having trouble. see the image below for an example.  https://www.alteraforum.com/forum/attachment.php?attachmentid=13601

What platform are you using? 

 At the moment you seem to be using the Cygwin to compile. Maybe switching to MinGW can solve this issue. Although at first glance I do not think this would lead to a fail for the build process.

You need to update the cygwin file of the altera software. You can download the newer version of cygwin from the site and update the same on your altera software. The cygwin files are located in the installed folder of the quartus>bin. you need to update both for 32 and 64 bit.

I am using NIOS II paltform for my project .. do you know the steps on how to switch to Cygwin MinGW? 

because actually I am very new to Eclipse and I'm still in the process of learning to use eclipse ..

For this you first need to got to the Cygwin site, download the 32 and 64 bit files and install the files in any drive of your computer. Then locate the cygwin files in the quartus software it will be inside the 32 bit in bin folder and 64 bit in bin64 of the Quartus software. Just overwrite the the cygwin files with the latest files you have downloaded.  Please let me know if you find and any trouble to update the cygwin files in quartus software.

tq dipslg89;226139 for reply my question..i already download both 32 and 64 bit Cygwin..but i don't really understand your explanation about this.. 

 "Then locate the cygwin files in the quartus software it will be inside the 32 bit in bin folder and 64 bit in bin64 of the Quartus software. Just overwrite the the cygwin files with the latest files you have downloaded."  maybe i understand but im afraid that im misunderstand it..really hope u can explain it again..:)

i already overwrite the 32 and 64 bit cygwin..but this error was popup..

So the software is unable to locate the g++ file. :cry:  you need to reinstall the software as the files are overwritten in the wrong location. After you install the Altera software again. Install the cygwin for 32 and 64 bit in any folder of your drive. No need to locate the Quartus software while installing the cygwin files as it will be a bit confusing. When you install the cygwin files in different folder of the drive two folder will create name as Cygwin and cygwin 64. First open the folder cygwin. it is for 32 bit. Inside you will see the files as "bin, dev, etc, home, library, cygwin.bat" and so on. Select all and copy the files in the location as altera<version<quartus<bin<cygwin. paste the files inside the cygwin folder of the quartus software, replace the files when a pop will appear. Repeat the same steps for cygwin 64 also. it will be in bin 64 of the quartus.   And bingo!!!!:cool:  Let me know if you face any problem while updating the files.

This error is due to the files are not installed correctly. Follow the steps I had mentioned. See in the error. Itself shows the location which is incorrect.
