- make `Makefile`
|
||||||
|
|
||||||
|
Change directory to `build` then run `cmake` to create Makefile. Once `Makefile` is generated you can run `make` command to build picrin.
|
||||||
|
|
||||||
|
$ cd build
|
||||||
|
$ cmake ..
|
||||||
|
|
||||||
|
Of course you don't need to move to `build` directory before running `cmake` (in that case `$ cmake .`), but I strongly recommend to follow above instruction.

When `make` command is called with an argument `debug`, it builds the binary with all debug flags enabled (PIC_GC_STRESS, VM_DEBUG, DEBUG).
