Buildroot local compiling method and system based on Shenwei architecture

The invention provides a Buildroot local compiling method and system based on an SW architecture, and belongs to the technical field of computers. The method comprises the steps that after it is determined that an issuing version operating system supported by the SW architecture is installed, the tool chain type is set to be an external tool chain; matching the configuration information of the GCC compiler of the external tool chain and the mk file compiled and referenced by the external tool chain with an issuing version operating system supported by the SW architecture; and copying a basic library file of a release version operating system supported by the SW architecture to a Buildroot local compiling file system directory through a user-defined script so as to complete the Buildroot local compiling. According to the Buildroot local compiling method and system based on the Shenwei architecture, the problem that the Shenwei architecture cannot use Buildroot to construct a file system and compile an open sou
