## Other options
Run with `--help` for more options.
Run with `-h` for more options.
# Building
Run `make` to build the normal binary. It will output to `shuffle3-release`.
## Release target
The `release` (default) target uses the variables `RELEASE_CFLAGS` and `RELEASE_LDFLAGS` to specify opitimisations. These can be set by you if you wish.
The `release` (default) target uses the variables `RELEASE_CFLAGS`, `RELEASE_CXXFLAGS` and `RELEASE_LDFLAGS` to specify opitimisations, as well as the `OPT_FLAGS` variable. These can be set by you if you wish.
### Note
The default `RELEASE_CFLAGS` contains the flag `-march=native`. This may be underisable for you, in which case set the variable or modify the makefile to remove it.
The default `OPT_FLAGS` contains the flag `-march=native`. This may be underisable for you, in which case set the variable or modify the makefile to remove it.
## Debug target
To build with debug information, run `make debug`. Extra debug flags can be provided with the `DEBUG_CFLAGS` and `DEBUG_LDFLAGS` variables which have default values in the Makefile.
To build with debug information, run `make debug`. Extra debug flags can be provided with the `DEBUG_CFLAGS`, `DEBUG_CXXFLAGS` and `DEBUG_LDFLAGS` variables which have default values in the Makefile.
The build and unstripped binary will be `shuffle3-debug`.
## Notes
Before switching between `release` and `debug` targets, remember to run `make clean`.
To disable stripping of release build binaries, run with `make STRIP=: release`
