I try to compile live555 library for eCos system. I don't pretty sure how to do this, so i try option build this under arm compiler. so as tutorial online. I type :
./genMakefiles armlinux
after that, i type : make and meet this error:
arm-elf-g++: Command not found
I think that arm-elf-g++ compiler that my machine doesn't install yet. I google, but no result how to install. (i'm currently using Ubuntu 13.04 64 bit). please tell me how to fix this.
Try something like this:
sudo apt-get install gcc-arm-linux-gnueabi
Here are a couple of links for installing an ARM toolchain on Ubuntu:

I am new to x64_86, but forced to use it because RedHat dropped its 32-bit OS support in RHEL 7.x. I have to complile a lot of code, and am not ready to jump to x64 yet (because I do not need 64-bit addresses and do not want to face all related porting issues). So I have considered using -m32 and -mx32, and decided that -mx32 is the best route for me. However, while -m32 works fine on my build machine, when I use -mx32, I get this error:
In file included from /usr/include/features.h:399:0,
from /usr/include/string.h:25,
from zz.cpp:1:
/usr/include/gnu/stubs.h:13:28: fatal error: gnu/stubs-x32.h: No such file or directory
# include <gnu/stubs-x32.h>
^
compilation terminated.
I searched the web for solutions and some links indicate that I have to install some mysterious "multilib" rpms for g++ and gcc, however, I cannot find these anywhere. Others suggest that I have to install Linux in the x32 mode and build libgcc for x32, which sound extreme. Any ideas or leads? Did someone actually try g++ -mx32? Maybe it is not even supported on the RH platform... Thanks!
P.S. In order to get the "-m32" option to work I had to install:
yum install glibc-devel.i686 libgcc.i686 libstdc++-devel.i686 ncurses-devel.i686
This one fails (yum cannot find these RPMs) - allegedly these are required for -mx32 to work:
yum install gcc-multilib g++-multilib
:(
Multilib is indeed your answer, but do not know why your repo does not support it. I installed mine via apt-get:
sudo apt-get install gcc-multilib
Although it uses 64-bit instructions, it uses the 32-bit ABI so annoyingly will not run under WSL (Windows Linux subsystem), which only supports the 64-bit one.
i am new to linux and I have the following question:
I am trying to install MINGW in Ubuntu.
I ran the command:
sudo apt-get install mingw-w64
It was installed, and if i put the command gcc it runs ok. The problem is g++ command does not work. I guess it is because i don't have the c++ compiler (as I read in similar questions in stackoverflow).
I read too that you can use the next command:
mingw-get install g++
but i don't have the executable program for this command.
My question is, how can I install that executable? or is there another way to update my mingw so I can use the g++ compiler?
Hope I have explained myself correctly. Thank you for any help I receive.
mingw-get is a windows specific package manager, it is not needed when you use a native linux package manager such as APT.
Installing package mingw-w64 depends on package g++-mingw-w64, which depends on g++-mingw-w64-i686 and g++-mingw-w64-x86-64.
These packages install the mingw cross compilers as
/usr/bin/x86_64-w64-mingw32-g++-posix
/usr/bin/x86_64-w64-mingw32-g++-win32
/usr/bin/i686-w64-mingw32-g++-posix
/usr/bin/i686-w64-mingw32-g++-win32
Older versions of mingw cross compiler shipped /usr/bin/i586-mingw32msvc-c++, which is replaced by i686-w64-mingw32-c++-win32
You can usually use this toolchain in a project by running ./configure CXX=i686-w64-mingw32-c++-win32 or make CXX=i686-w64-mingw32-c++-win32
Note: the above description is correct for the most recent toolchain in Debian unstable. It may need some minor tweaking for older systems.
I am getting this error when i tried to compile my program
-bash: g++: command not found
Also I have only been getting this error after I formatted my Mac Book Pro
This error came after I did this
g++ functions.cpp
Please help me.
Thank You
Here is a cleanest solution than installing XCode just for Gcc.
STEP 1 > install this:
[HomeBrew Web Site] (http://brew.sh/)
All the informations concerning the installation and the utility of such a program are on the site itself.
It's a package manager, but for Mac. It's like apt-get or yaourt, if you ever used Ubuntu or Arch Linux.
STEP 2 > Go to the Terminal application and type :
$> homebrew search gcc
Then choose from the version you want, and type again in Terminal:
$> homebrew install [choosen version]
Gcc is now installed.
I get the following link error when I'm compiling a small function using ncurses for an Ubuntu 12.04 running on arm. The error is
arm-linux-gnueabihf/bin/ld: cannot find -ltinfo
A lot of hints are floating around on what to install, but I can't seem to find any packages that does the trick for my arm box.
I have done
sudo apt-get install libncurses5-dev
And this does not contain the tinfo library. Other suggestions usually result in the library is "not available but referred by another package" or "has no installation candidate".
All help is appreciated

As mentioned by lucasg
sudo apt-get install libtinfo-dev
solved the same problem for me.
When you cross compile the nurses library, configure this option --with-termlib. It shall install libtinfo into your target location.
In Ubuntu, there is a package called uuid-dev. To install and use it, I just need to run apt-get install uuid-dev. However, in MinGW, I couldn't install this package using mingw-get install.
May I know what are the basic steps to port a C++ application/library from Ubuntu to MinGW?
It might already support compilation under MinGW. Generally you would download the source, unpack them and run ./configure and see what happens.
Give that a try and get back to me.
