Hi all,
On a current C++ project I'm using Autoconf and Automake.
To solve the big subdir tree inside src I used VPATHs in my
Makefile.am, if there's another way please say so.
The current problem is due to the fact that using automake with bison
and flex is giving me headaches.
I have msat-parser.yy and msat-parser.ll which generate C++ code.
And in my Makefile.am I have:
AM_YFLAGS = -d
AM_LFLAGS = -i -Cfa -+ -o$(LEX_OUTPUT_ROOT).cc
BUILT_SOURCES = msat-parser.h
bin_PROGRAMS = test
test_SOURCES = msat-parser.yy msat-lexer.ll ...
While doing make I get:
bison -y -d parser/msat/msat-parser.yy
if test -f y.tab.h; then \
to=`echo "msat-parser_H" | sed \
-e 'y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/' \
-e 's/[^ABCDEFGHIJKLMNOPQRSTUVWXYZ]/_/g'`; \
sed -e "/^#/!b" -e "s/Y_TAB_H/$to/g" -e "s|y\.tab\.h|msat-parser.h|" \
y.tab.h >msat-parser.ht; \
rm -f y.tab.h; \
if cmp -s msat-parser.ht msat-parser.h; then \
rm -f msat-parser.ht ;\
else \
mv msat-parser.ht msat-parser.h; \
fi; \
fi
if test -f y.output; then \
mv y.output msat-parser.output; \
fi
sed '/^#/ s|y\.tab\.c|msat-parser.cc|' y.tab.c >msat-parser.cct && mv
msat-parser.cct msat-parser.cc
rm -f y.tab.c
make all-am

Does anyone know what the problem might be? Thanks a lot.
Cheers,
