Netbeans 7.2 shows “Unable to resolve identifier” , although build is successful

Question

I\'m using the Netbeans IDE 7.2 with C/C++ plugin (last version 1.18.1.1) and if I build my project everything is fine but the IDE show me

Answer 1

Mine worked once i renamed my main.c to main.cpp.

Based on the file extension, the behavior of Netbeans Code Assistance changes

Answer 2

Here's an excerpt from my answer to another question.

Unresolved Identifier

If the source of the .cpp file looks like this

Click with the right mouse button on your project.
Check C/C++ Code As...
Run Reparse Project.

If that is not enough.
Go to Project Properties
Fill in the Include input field as described.

Set the include path correct.

I hope that can help you.

Answer 3

i had the same problem, but i recognized it appears after i changed properties-> c++ compiler -> Compilation Line -> additional options to -std=c++11. if change the settings to default the error "unable to resolve identifier" disapears.

Answer 4

try Click by Right button the file, Properties->General->Exclude from code assistance (disable)

Answer 5

I often have this error, and as others mentioned, usually I add space character, save the file, remove the space character... and all identifiers are solved.

This time it did not work. My project, which I compiled thousand times, and it always worked, suddenly crashed MPLAB X IDE v3.35 (Mac OSX, but likely it doesn't matter), while typing text. After this I have in one file only and for one structure only, all identifiers unresolved.

Structure in profile.h file was:

typedef struct
{
    int state;                      ///< state machine current state
    int enabled;                    ///< machine can be ENABLED or DISABLED
    int flag;                       ///< to initiate profile execution
   ... many variables here ...
    unsigned long timestamp;        ///< variable used for local timing
} profile_struct;

In my profile.c file any variables from this structure became unresolved, but project compiled and worked fine.

After a frustrating hour of trying, this solved my problem: Erased the whole MPLABX cache directory.

In my case, it is located at:

/Users/USER_NAME/Library/Caches/mplab_ide/dev/v3.35/var

(need to erase the whole 'var' directory; and of course replace the USER_NAME with your user name)

Note, that the 'Library' is a hidden directory, but you can still access it if you enable viewing hidden files, or go straight to it via terminal.

Lastly, on your computer it might be somewhere else. I found mine by watching, which files were modified on my computer in the last 2 minutes, by using the terminal command:

/usr/bin/find /Users/USER_NAME/ -mmin -2 –ls

Answer 6

I am using NetBeans 8.1 and the same problem popped up when I started a new C++ project. It solved itself after running the project through the debugger.
