Linux, GCC, and unanswered questions
closed account (3hM2Nwbp)
I've been crawling around the GNU/Unbutu websites for hours trying to find answers, with no such success. I expect that they can be answered by someone who's actually installed / fiddled around with these things. I haven't had any experience with these GNUish things before, but I do want to start testing my code on a platform other than Windows.
* Does Unbutu Desktop Edition come stock with C++0x support in the GCC compiler that it has? (It has a stock GCC compiler, right?) If not, how big of a hassle is it to set a C++0x compiler up for it?
* What C++0x features live in the
* I've also read that boost might come stock on Unbutu, but have noticed a large number of threads on the Unbutu site with problems building boost. Some solutions were to install a few other tools to build it (remember, I'm a Linux newb here), and it just seemed like a huge headache.
Thanks,
Luc

std namespace in GCC4.5 (4.6?) IE. would I need to build boost on the system to access the (soon to be standard [std::shared_ptr : boost::shared_ptr]) smart pointers? Microsoft's compiler has the std::tr1 namespace, does GCC also?* I've also read that boost might come stock on Unbutu, but have noticed a large number of threads on the Unbutu site with problems building boost.

From what I've read/worked with, the default install (I'm still using 10.04 I believe) comes with GCC 4.5.2, which I believe has a bit of 0x already working. [I'm often wrong]
After reading this http://gcc.gnu.org/gcc-4.6/cxx0x_status.html it seems you just need to upgrade GCC... [again, I'm often wrong]
Dunno.
also dunno. While I really should, i'm not using any boost features atm.
Good luck with the installation process, it can be tough at first.

You'll need to install the build-essential package on Ubuntu to get C++ working:
apt-get install built-essential (add sudo to the beginning if you aren't root).
I think Linux Mint is better for beginning on Linux. It's the Ubuntu system but modified to be more user friendly for new users. As far as C++0x, I have been using some 0x code without any trouble. It gives me a warning about things but it is capable on compiling the code anyway. I use g++ to compile C++ code however, and gcc for C.
If you want to compile C++ code with gcc, use
gcc -E. I don't know if it makes a difference to use that or g++... I would assume gcc -E just invokes g++.

Hours? Just download VMware Player, install Ubuntu, and check it out!

Hmm...unable to connect to the net, can't compile int main(){return 0;}...and the default installation is well, very purple. Guess another night will be wasted trying to configure things rather than laying some code.
Normally this wouldn't be an issue but using
...whatever I'm sticking with windows this is a losing battle. 80-90% of the google hits threads' were still unresolved.

I always use the DVD rather than the live CD... It's on the Ubuntu site but you have to click around "alternative downloads" after going to the download page to find it.
I'm pretty sure GCC is installed by default but I'll double check later today.

Ok, after a clean install of Ubuntu 10.10, g++ is not installed by default. Trying to run it displays the command to install it, though.
