The following is generic code to set up an environment: "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" architecture Microsoft has provided free-of-charge versions of Visual Studio for many years.Īll of the environments can be automatically accessed by creating shortcuts to them as Visual Studio 2015 does or manually by executing the batch file with the relevant argument in Command Prompt. It is installed during the installation of Visual Studio 2015. The Visual C++ toolset is used for software development in both C and C++. VS2015 x86 ARM Cross Tools Command Prompt Command Prompt environment setup comparison Shortcut The environment it sets up is intended for development of software targeting. One of the shortcuts is different in that the batch file it runs is called VsDevCmd.bat and it takes no arguments. The argument corresponds roughly to the name of the shortcut. The only difference between the shortcuts is the argument that gets passed to the batch file. The purpose of the batch file is to set the necessary environment variables for the Command Prompt session. The Command Prompt executed by the shortcuts gets passed a batch file ( vcvarsall.bat) as an argument and another argument intended for the batch file itself. The Target textbox contains the instantiation of Command Prompt ( %comspec%) and the arguments passed to it. The arguments passed to the Command Prompt instance can be seen by right-clicking the shortcuts and selecting Properties.
These shortcuts start Command Prompt with pre-defined arguments. It is important to note that the tools provided by Visual Studio 2015 are not actual command-line interpreters but simply shortcuts to Command Prompt. The Microsoft Windows operating system possesses a command-line interpreter called Command Prompt (cmd.exe). Native/Cross tools comparison Input architecture An example of input could be source code and an example of output could be a binary. Native tools output for the same architectures as they are being run on and cross tools output for different architectures than those which they are being run on. Microsoft offers two flavours of tools called native tools and cross tools. Note that Microsoft may not always use the official architecture names for its products. The latest version of Microsoft Windows runs on 3 architectures. The instruction set and CPU design are together called architecture. Many instruction sets exist but few are prevalent. Source code is compiled into instructions that the computer understands. Note that some CPUs may be backward compatible, therefore 64-bit computers may process 32-bit and 16-bit data and 32-bit computers may process 16-bit data. Support for 16-bit units is still common but undesirable and archaic. Data sizesĬomputers process data in 32-bit or 64-bit units.
The following terminology must be clearly understood in order to select the appropriate software build environment.
