@ -21,6 +21,25 @@ Requires [CMake](https://cmake.org), [yasm](https://yasm.tortall.net), and
your favorite c-compiler & build tool. Results have been obtained using Visual
Studio 2019, gcc&make on linux, and MinGW&mingw32-make.
### Example: building and testing using MinGW32
```
mkdir build
cd build
cmake .. -G"MinGW Makefiles"
mingw32-make
mingw32-make test
cd ../bridge
go test
```
Note that this builds 64-bit binaries on 64-bit Windows. To build 32-bit
binaries on 64-bit Windows, replace in above:
```
cmake .. -DCMAKE_C_FLAGS="-m32" -DCMAKE_ASM_NASM_OBJECT_FORMAT="win32" -G"MinGW Makefiles"
```
> :warning: **If you are using MinGW**: Yasm 1.3.0 (currently still the latest
stable release) and GNU linker do not play nicely along, trashing the BSS layout.
