Help for a Beginner in Codelite Ubuntu

[reddy]

I have downloaded Codelite for Ubuntu and installed on my PC. I just ran " Hello World " to get familiar with controls. And this is the output I am getting after trying to build and run the project even there aren't any errors in my program.

/bin/sh -c '/usr/bin/make -j4 -e -f Makefile'
----------Building project:[ k - Debug ]----------
make[1]: Entering directory '/home/swet/Desktop/k'
/usr/bin/gcc-4.8 -c "/home/swet/Desktop/k/k.c" -g -O0 -Wall -o ./Debug/k.c.o -I. -I.
/usr/bin/g++-4.8 -o ./Debug/k @"k.txt" -L.
/bin/sh: 1: /usr/bin/g++-4.8: not found
k.mk:76: recipe for target 'Debug/k' failed

make[1]: Leaving directory '/home/swet/Desktop/k'
Makefile:4: recipe for target 'All' failed
make: *** [All] Error 2
1 errors, 0 warnings

Although I can still run the code, I don't want to see that error warning. I would really appreciate if you could help me out how to eliminate that error warning.

Do you have g++ installed?
For me, it exists:

Code: Select all

eran@ubuntu-14-04-64:~$ ls -l /usr/bin/g++-4.8 
-rwxr-xr-x 1 root root 775888 אפר  5  2014 /usr/bin/g++-4.8

Try installing the build-essential package:

Code: Select all

sudo apt-get install build-essential

This should fix it

It didn't work. It is showing build essential is already newest version.

Hi,

In my experience, ubuntu installs the 'g++' package by default. I'm fairly sure it did so for my ubuntu 14.04 VBox guest (I presume it's 14.04 that you're using).

What is the output of doing:
ls -l /usr/bin/g++*

Also try doing:
g++ -v

If these suggest that g++ isn't installed, do:
sudo apt-get install g++

Regards,

David

[reddy]

g++ is installed by default.

Nevertheless I still checked it in terminal by running

ls -l /usr/bin/g++*

lrwxrwxrwx 1 root root 7 Sep 5 00:32 /usr/bin/g++ -> g++-4.9
-rwxr-xr-x 1 root root 810824 Oct 11 14:36 /usr/bin/g++-4.9

For g++ -v

It still didn't work for me. The error still exists unfortunately.

Above it shows g++ 4.8, but below it shows that g++ 4.9 is the one installed. Try re-selecting a default compiler. Also, try this from the command line:

Code: Select all

cd /home/swet/Desktop/k
g++ -c k.c -g -O0 -Wall -o ./Debug/k.c.o

And see if it compiles to the ./Debug/k.c.o location.

[eranif]

go to: settings->build settings->compilers

find the compiler you are using, and change tools to point to g++-4-9 instead of g++-4.8
OR:
settings->build settings->compilers->Add compilers->scan computer for installed compilers

and it should pick the g++-4.9 compiler
Try to build your project again
