Hi
I am having trouble using automake to build a libtool library with
multiple lex sources using flex. Hopefully there is some feature I
have overlooked, but it seems like there is no easy way to do this :(
The automake docs claims that the ylwrap script solves the problem
with including multiple yacc or lex source fles in a single program,
but it seem to only solve a very small part of the problem.
In my Makefile.am:
lib_LTLIBRARIES = libpcsclite_core.la
libpcsclite_core_la_SOURCES = configfile.l bundleparser.l \
....
When I link this, I get the expected symbol conflicts. By rewriting
bundleparser.l so it uses a different prefix than yy (bp in this
case), and using the -P option of flex, I can get everything working
nicely. But how to do this with automake ? There seems to be several
problems with this.
bundleparser_lo_LFLAGS = -Pbp
doesn't seem to do anything.
LFLAGS = -Pbp
on the other hand, do "something". Unfortunately it breaks ylwrap
functionality as LEX_OUTPUT_ROOT is a fixed value, which is not the
case with the flex -P option.
So my questions are
1) How do I specify flex options for a specific lex source file ?
2) How do I specify a "-P" option with correct handling of
LEX_OUTPUT_ROOT ?
I have tried with the current autoconf/automake/libtool release
versions CVS HEAD.
