How to get g++ and gcc to work?

[kalle314]

I used Synaptic to download and install the packages I thought I would need:

gcc (4:3.3.5-1)
g++ (4:3.3.5-1)
libg++27 (2.7.2.1-19)
libgcc1 (1:4.0.0-7ubuntu...)

and some other packages that were included automatically.

The helloworld program works fine for g++, but for gcc I got

"/tmp/cc0f2Ifm.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status".

I have two larger c++ programs that can be compiled by gcc and g++ in solaris and cygwin (and runs fine) , but neither of these programs can be compiled now (both gcc and g++ fails to compile.)

(For example, I get parsing errors and
"/usr/include/langinfo.h:48: error: `__LC_TIME' was not declared in this scope
/usr/include/langinfo.h:48: error: enumerator value for `ABDAY_1' not integer
constant
/usr/include/langinfo.h:241: error: `__LC_COLLATE' was not declared in this
scope".)

What shall I do?

If you need those libraries for compiling try using #sudo apt-get install build-essential. Those are all the packages needed for building, compiling, etc. Hope that fixes your problem.

You may need to remove the few that you've already installed.

Thanks for the quick answer :)

I did "sudo apt-get install build-essential", but I still get the same compilation errors :-?
gcc produces errors when I'm trying to compile helloworld.
g++ manages to compile helloworld, but fails for a bigger program (a rather easy one, only a header file and a .C-file.)


(When I try to remove any of the packages I installed , Synaptic warns that I am about to remove essential packages, which might damage the system.) edit: solved.

edit again: Now gcc compiles helloworld without problem.

Most of my problems are solved now - there wasn't a single easy solution, but I had to do many small different things, like

* downloading packages with headers that were missing, like Xutil.h, Xlib.h, Xatom.h,...
* link to headers that the compiler didn't find. Maybe this could be done once and for all? I did it by swiches in the makefile anyway.
* writing ./a.out instead of a.out when running
* writing "sudo make" instead of only "make" - otherwise files (located in my own home directory) that needed to be written to couldn't be accessed.

Are there more things to think about when compiling c++ in ubuntu?

What a pain in the butt! I still can't get anjuta to create a single wizard project, let alone something I wrote up from scratch. I wish somebody would package it up into one neat bundle so all you have to do is install it and go. ](*,)
