|
| 15 | Usage:
|
| 16 | _build/oils.sh FLAG*
|
| 17 | _build/oils.sh --help
|
| 18 |
|
| 19 | Flags:
|
| 20 |
|
| 21 | --cxx CXX [default 'cxx']
|
| 22 | The C++ compiler to use: 'cxx' for system compiler, 'clang', or custom
|
| 23 | string
|
| 24 |
|
| 25 | --variant ARG [default 'opt']
|
| 26 | The build variant, e.g. dbg, opt, asan, which adds compile and link flags.
|
| 27 |
|
| 28 | --translator ARG [default 'mycpp']
|
| 29 | Which bundle of translated source code to compile: mycpp, mycpp-souffle
|
| 30 |
|
| 31 | --skip-rebuild
|
| 32 | If the output exists, skip the build
|
| 33 |
|
| 34 | Env vars respected:
|
| 35 |
|
| 36 | OILS_PARALLEL_BUILD= [default 1]
|
| 37 | Set to 0 to disable parallel compilation.
|
| 38 |
|
| 39 | OILS_CXX_VERBOSE= [default '']
|
| 40 | Set to 1 to show build details.
|
| 41 |
|
| 42 | Compile/link flags:
|
| 43 |
|
| 44 | BASE_CXXFLAGS= (defined in build/common.sh)
|
| 45 | Override this to disable basic flags like -fno-omit-frame-pointer
|
| 46 |
|
| 47 | CXXFLAGS= [default ''] (defined in build/ninja-rules-cpp.sh)
|
| 48 | Space-separated list of more compiler flags
|
| 49 |
|
| 50 | LDFLAGS= [default ''] (defined in build/ninja-rules-cpp.sh)
|
| 51 | Space-separated list of more linker flags
|
| 52 |
|
| 53 | Compiler flags come from these sources:
|
| 54 |
|
| 55 | 1. The $BASE_CXXFLAGS var
|
| 56 | 2. -I $REPO_ROOT is hard-coded
|
| 57 | 3. The build --variant, e.g. 'asan' adds -fsanitizer=address and more
|
| 58 | 4. Flags detected by ./configure, e.g. for GNU readline
|
| 59 | 5. The $CXXFLAGS var
|
| 60 |
|
| 61 | Linker flags come from these sources:
|
| 62 |
|
| 63 | 1. The build --variant, e.g. 'asan' adds -fsanitizer=address
|
| 64 | 2. Flags detected by ./configure, like $STRIP_FLAGS and -lreadline for GNU
|
| 65 | readline
|
| 66 | 3. The $LDFLAGS var
|
| 67 |
|
| 68 | EOF
