NetBeans not able to include files

Question

• IDE: NetBeans 6.8
• OS: Fedora 12

I have been having this problem for a long time now. NetBeans is almost impossible to use with C/C++, maybe because it was not made for it in first place.

Anyways what happens is this: I have this setup for C/C++

But, the programs are displayed like this:

It is not able to find any header file!! I know it is a C++ program, the same thing happens with #include <cstdio>. As a result, it is not able to find the definition of printf and fails.

Same thing happens with a .c file.

Also, gcc works fine from the command line.

---

the problem exists still:

$ find / -name stdlib.h
/usr/include/bits/stdlib.h
/usr/include/c++/4.4.3/tr1/stdlib.h
/usr/include/stdlib.h
/usr/share/syslinux/com32/include/stdlib.h
/usr/arm-gp2x-linux/include/stdlib.h

Did someone face this problem before? What do I need to do to make this work?

Answer 1

You should go on the tab "Code Assistance" and check the include paths. Happened to me that the paths referenced something like

/usr/lib/gcc/i486-linux-gnu/4.3/include

but i upgraded to gcc 4.4, so i had to change that to

/usr/lib/gcc/i486-linux-gnu/4.4/include

hope that helps

EDIT

Seems from your screenshots that Netbeans doesn't look in all your include paths. Please make sure that all your include paths are contemplated under "Code Assistance"

Answer 2

Mine works. These are my settings:

In Options -> C/C++ -> Code Assistance Tab -> C compiler tab ->

I have the following in the "include directories"

/usr/local/include
/usr/lib/gcc/x86_64-linux-gnu/4.4.3/include
/usr/lib/gcc/x86_64-linux-gnu/4.4.3/include-fixed
/usr/include

The last one /usr/include is the one that should have stdio.h and stdlib.h.

I was able to get the C++ code assistance to work by adding /usr/include/c++/4.4.3 in the c++ code assistance tab.

Edit: Your find command seems to have found all the relevant directories. Looks like you might just have to add them to the code assistance tab.

I had the same problem with NB 6.9 and solved by updating all my C++ plugin's (Tools > Plugin).
