- Generate an analyser from a flex file:
|
||
|
|
|
||
|
|
`lex {{analyser.l}}`
|
||
|
|
|
||
|
|
- Specify the output file:
|
||
|
|
|
||
|
|
`lex {{analyser.l}} --outfile {{analyser.c}}`
|
||
|
|
|
||
|
|
- Compile a C file generated by flex:
|
||
|
|
|
||
|
|
`cc {{path/to/lex.yy.c}} --output {{executable}}`
