| # kvm-unit-tests on macOS |
| |
| Cross-compiler with ELF support is required for build of kvm-unit-tests on |
| macOS. |
| |
| ## Building cross-compiler from source |
| |
| A cross-compiler toolchain can be built from source using crosstool-ng. The |
| latest released version of |
| [crosstool-ng](https://github.com/crosstool-ng/crosstool-ng) can be installed |
| using [homebrew](https://brew.sh) |
| ``` |
| $ brew install crosstool-ng |
| ``` |
| |
| A case-sensitive APFS/HFS+ volume has to be created using Disk Utility as a |
| build and installation directory for the cross-compiler. Please [see Apple |
| documentation](https://support.apple.com/guide/disk-utility/dsku19ed921c/mac) |
| for details. |
| |
| Assuming the case-sensitive volume is named /Volumes/BuildTools, the |
| cross-compiler can be built and installed there: |
| ``` |
| $ X_BUILD_DIR=/Volumes/BuildTools/ct-ng-build |
| $ X_INSTALL_DIR=/Volumes/BuildTools/x-tools |
| $ mkdir $X_BUILD_DIR |
| $ ct-ng -C $X_BUILD_DIR x86_64-unknown-linux-gnu |
| $ ct-ng -C $X_BUILD_DIR build CT_PREFIX=$X_INSTALL_DIR |
| ``` |
| |
| Once compiled, the cross-compiler can be used to build the tests: |
| ``` |
| $ ./configure --cross-prefix=$X_INSTALL_DIR/x86_64-unknown-linux-gnu/bin/x86_64-unknown-linux-gnu- |
| $ make |
| ``` |
| |
| ## Pre-built cross-compiler |
| |
| x86_64-elf-gcc package in Homebrew provides pre-built cross-compiler but it |
| fails to compile kvm-unit-tests. |
| |
| ## Running the tests |
| |
| GNU coreutils should be installed prior to running the tests: |
| ``` |
| $ brew install coreutils |
| ``` |
