Hi,
I'm trying to add support for Modula-2 in gnu gcc and I'm currently
writing the 'gcc-versionno/libgm2/Makefile.am' for the runtime
libraries. Modula-2 has a number of runtime libraries (pim, iso, min)
and each are built using their own flags. I see with C, C++ that the
libraryname_a_CFLAGS
is honoured when producing the .o from the .c sources. It would be
really useful if the same could be done for Modula-2 when producing
the .o from .mod rules, so for example:
libmin_a_M2FLAGS = -Igm2-libs-min -I$(GM2_SRC)/gm2-libs-min
etc
libpim_a_M2FLAGS = -Igm2-libs -I$(GM2_SRC)/gm2-libs
etc
libiso_a_M2FLAGS = -Igm2-iso -I$(GM2_SRC)/gm2-iso.
My questions fall into two categories:
(i) how much work is it to implement the Modula-2 production
of rules which use M2FLAGS in the same way as C uses CFLAGS?
Also where is a good place to start - the C compiler or
f77?
(ii) would it be possible to produce a m2local.m4 file which my
Makefile.am could include to provide a temporary fix for
Modula-2 support? Or does language support go deeper
than just a few macros? Apologies for my ignorance about
m4 in general.
I see that this was discussed sometime ago for the D language:
https://lists.gnu.org/archive/html/autoconf/2007-10/msg00044.html
which I think in someway might answer (i), but it was a while ago
and I just wanted to check this is still the case,
regards,
Gaius
