Hi,
While trying to utilize Autotools in a preexisting project that previously just relied on Makefiles, I came across ylwrap failing for some absurd, unknown reason. I couldn't help but run sh -x and debug it piecewise. So what's ultimately done is running flex inside a temp directory, flex /home/jengelh/code/iproute2/tc/emp_ematch_lex.l It turns out flex produces a file called lex.ematch_.c, which is something ylwrap so does not expect at all - it only checks for what's in pairlist="yy.lex.c emp_ematch_lex.c". I can use AM_LFLAGS = -o yy.lex.c to work around it, but that feels like an ugly hack. What's up with flex here? thanks, Jan
