well, instead of adding -I$(srcdir)/gllib, I symlink (shudder!!!) the
necessary headers into -I$(builddir):
in makemake.in:
GLLIB_MODULE_HEADERS="regex.h"
for f in localcharset.h ${GLLIB_MODULE_HEADERS} ${UNICODE_EXTRA}; do
link_dep "${f}" `find ${SRCDIR}gllib/ -name ${f}`
done
which results in
regex.h : ../src/gllib/regex.h
-$(RM) regex.h
-$(LN_S) ../src/gllib/regex.h regex.h
streq.h : ../src/gllib/streq.h
-$(RM) streq.h
-$(LN_S) ../src/gllib/streq.h streq.h
cjk.h : ../src/gllib/uniwidth/cjk.h
-$(RM) cjk.h
-$(LN_S) ../src/gllib/uniwidth/cjk.h cjk.h
uninames.h : ../src/gllib/uniname/uninames.h
-$(RM) uninames.h
-$(LN_S) ../src/gllib/uniname/uninames.h uninames.h
the reason I cannot do -I$(srcdir)/gllib is clear: it will not catch
uninames.h & cjk.h.
on the other hand, it does not look like streq.h, uninames.h and cjk.h
are included in any clisp sources (only in gnulib).
so, I guess TRT is to remove the linking and add -I$(srcdir)/gllib to CPPFLAGS..
