It is much easier to compile it on the target OS than cross compiling it. What you need is a toolchain for every OS and a “make” tool. CMake has powerful crosscompiling abilities. This is not a necessity, but it will save some money: Get virtualization software (e.g. VMWare Player is free) and run on … Read more
For building single docker images: Set your environment variable using the command line or modifying your .bashrc or .zshenv file. (introduced in v19.03.0 in 03/2019) export DOCKER_DEFAULT_PLATFORM=linux/arm64 Alternatively, in the Dockerfile, include the following flag in the FROM command (for a multi-stage Dockerfile build, the flag is only needed for the first stage): FROM –platform=linux/arm64 … Read more
To build from Linux to Windows, you need to set the environment variables GOOS to Windows and GOARCH to amd64. On Bash or ZSH: % GOOS=windows GOARCH=amd64 go build For more details see: https://dave.cheney.net/2015/08/22/cross-compilation-with-go-1-5 A description of possible values for GOOS and GOARCH is available here: https://golang.org/doc/install/source#environment If your package requires CGO then you need … Read more
try passing the –host option to configure which will cause all the cc ar etc utilities to prefix with armv7l-unknown-linux-gnueabihf- eg: ./configure –host=armv7l-unknown-linux-gnueabihf –build=i686-unknown-linux-gnu Since you are using configure with hopefully autotools take a look at: automake Cross compiling
If you want to use a toolchain file there is an easier solution (IMHO) than what is proposed by @auledoom. You do not need to write the shell wrapper scripts at all, simply put this in the toolchain file: # the name of the target operating system set(CMAKE_SYSTEM_NAME Linux) # Which compilers to use for … Read more
If you are using a Mac, you can select MacOS GCC instead of Cross GCC. If you are on Windows, you will have to install a C++ compiler. I recommend you install Cygwin, try following the directions here. https://www3.ntu.edu.sg/home/ehchua/programming/howto/eclipsecpp_howto.html Once you’ve installed the C++ compiler, restart Eclipse and try to create the project again. Hope … Read more
If you look at the file lists on the Ubuntu package webserver for mingw-w64‘s constituent packages: gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 binutils-mingw-w64-x86-64 mingw-w64-x86-64-dev gcc-mingw-w64-i686 g++-mingw-w64-i686 binutils-mingw-w64-i686 mingw-w64-i686-dev You can see that mingw-w64 provides a toolchain, i.e. a set of alternative tools (compiler, linker, headers, etc.) used to compile your code for another system. Assuming you want to compile … Read more
Putting ARCH and CROSS_COMPILE in the Makefile doesn’t work. You need to put them on the command line: make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
Regarding your general questions: Why the C library works: The C library is part of your cross toolchain. That’s why the headers are found and the program correctly links and runs. This is also true for some other very basic system libraries like libm and libstdc++ (not in every case, depends on the toolchain configuration). … Read more
