| Subject: [PATCH] tc: fix parallel build file with lex/yacc |
| |
| Building iproute2 in parallel might hit the race failure: |
| emp_ematch.l:2:30: fatal error: emp_ematch.yacc.h: |
| No such file or directory |
| make[1]: *** [emp_ematch.lex.o] Error 1 |
| |
| This is because we currently allow the yacc/lex files to generate and |
| compile in parallel. So add a simple dependency to make sure yacc has |
| finished before we attempt to compile the lex output. |
