What is the package name of arm-linux-gnueabihf 64bit gcc compiler under ubuntu to install using apt-get?
I am having amd64 and while i am installing gcc-arm-linux-gnueabihf through apt-get, it is installing 32bit compiler. But i want to install 64bit as well. Kindly let me know how to install 64bit compilers?

I need to build a library from C sources for Arm aarch64 architecture and Linux Ubuntu x86 64 using GCC toolchain - my host work machine is Ubuntu 20.04 too.
For Arm there are GCC toolchains available for download at developer.arm-com.
What I do for Arm is:
download the zipped toolchain
unzip it to a /temp directory
build the library telling the underlying build system to use GCC from /temp/gcc
I would like to do the same for Linux x86 64, so, instead of Arm, target Linux Ubuntu x86 64. I don't want to use the GCC natively installed on the system.
Where do I find the GCC toolchain targeting Ubuntu x86 64 architecture?
I have found the https://packages.ubuntu.com/focal/amd64/gcc/download page. There I got the gcc_9.3.0-1ubuntu2_amd64.deb package. Can I "temporarily unzip" the deb, in order to use GCC without installing it on the system? Is there a zip instead of only deb?
I've installed BuildRoot, to set a SoftetherVPN.
Well, my problem is that I necessary need to install GCC, in a 32-bit ARM Architecture, (obviously I've downloaded the 32 bit version).
I looked all over the internet, because of many problems:
My first idea was to install GCC using command sudo apt-get or sudo yum, but I can only find it in Debian Linux (Buildroot kernel, and its toolchain are very reduced).
At this point I tried to cross-compiling GCC but with no results, because it produced in shell output Library errors. And I also tried to paste those missing libraries yet achieve very little.
You could download some GCC cross-compiler. For example, if your PC is running some Debian-like Linux distribution -perhaps Ubuntu- you might install some gcc-7-arm-linux-gnueabi or similar (gcc-7-arm-linux-gnueabihf ...) package.
The SDK for your board is likely to provide some cross-GCC & cross-binutils.
You could build some cross binutils then some GCC cross-compiler from their source code (this is a bit more tricky).
Your cross-compiler would compile (for ARM) on your Linux-running PC, not on your ARM circuit board.
I have written some effects in C++ (g++) using freeglut on Linux, and I compile them with
g++ -Wall -lglut part8.cpp -o part8
So I was wondering if it is possible to have g++ make static compiled Windows executables that contains everything needed?
I don't have Windows, so it would be really cool, if I could do that on Linux :)
mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.
Ubuntu, for example, has MinGW in its repositories:
$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows
[...]
Suggested method gave me error on Ubuntu 16.04: E: Unable to locate package mingw32
===========================================================================
To install this package on Ubuntu please use following:
sudo apt-get install mingw-w64
After install you can use it:
x86_64-w64-mingw32-g++
Please note!
For 64-bit use: x86_64-w64-mingw32-g++
For 32-bit use: i686-w64-mingw32-g++
One option of compiling for Windows in Linux is via mingw. I found a very helpful tutorial here.
To install mingw32 on Debian based systems, run the following command:
sudo apt-get install mingw32
To compile your code, you can use something like:
i586-mingw32msvc-g++ -o myApp.exe myApp.cpp
You'll sometimes want to test the new Windows application directly in Linux. You can use wine for that, although you should always keep in mind that wine could have bugs. This means that you might not be sure that a bug is in wine, your program, or both, so only use wine for general testing.
To install wine, run:
sudo apt-get install wine
Install a cross compiler, like mingw64 from your package manager.
Then compile in the following way: instead of simply calling gcc call i686-w64-mingw32-gcc for 32-bit Windows or x86_64-w64-mingw32-gcc" for 64-bit Windows. I would also use the --static option, as the target system may not have all the libraries.
If you want to compile other language, like Fortran, replace -gcc with -gfortran in the previous commands.
I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.
I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.

As of Fedora 17 it is possible to easily build (cross-compile) binaries for the win32 and win64 targets. This is realized using the mingw-w64 toolchain: http://mingw-w64.sf.net/. Using this toolchain allows you to build binaries for the following programming languages: C, C++, Objective-C, Objective-C++ and Fortran.

For Fedora:
# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"
# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

How is it possible to compile packages for Cygwin? I want to use the second factor authentication for SSH. So I need the packages libpam-otpw and otpw-bin for cygwin. Is is possible to compile these Debian packages for Cygwin, because the packages are not in the official cygwin sources.
