sent upstream already From f8a783bbe98b0fe5aaedbf623bc70471b88c9187 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 18 Oct 2011 17:36:55 -0400 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.
