problem building grass trunk

[Stefano Salvador]

Hi,

I'm trying to compile revision 39598 of grass trunk but I get a list
of undefined symbol for almost all modules, the output of make is:

/root/grass_trunk/lib/form
/root/grass_trunk/lib/vector/diglib
/root/grass_trunk/lib/init
/root/grass_trunk/db/drivers/dbf

[... many more ...]


if I run make in the first library with errors I get:

the system is SUSE 10 with gcc 4.1, I have removed each previous
installation of grass.


any hint ?

Well, that's where it's going wrong.

I suspect that it's related to r38871, which uses $(eval $(call ...))
to define the *_LIBNAME, *LIB and *DEP variables:

        libs = \
                ARRAYSTATS:arraystats \
                BASIC:basic \
                BITMAP:bitmap \
        ...
       
        define lib_rules
        $(1)_LIBNAME = grass_$(2)
        ifneq ($(NEED_DEPS),)
        $(1)LIB = -l$$($(1)_LIBNAME) $$($(1)DEPS)
        else
        $(1)LIB = -l$$($(1)_LIBNAME)
        endif
        ifneq ($(1),IOSTREAM)
        $(1)DEP = $$(BASE_LIBDIR)/$$(LIB_PREFIX)$$($(1)_LIBNAME)$$(LIB_SUFFIX)
        else
        $(1)DEP = $$(BASE_LIBDIR)/$$(STLIB_PREFIX)$$($(1)_LIBNAME)$$(STLIB_SUFFIX)
        endif
        endef
       
        $(foreach lib,$(libs),$(eval $(call lib_rules,$(firstword $(subst :, ,$(lib))),$(lastword $(subst :, ,$(lib))))))

It looks as if $(1) is set okay, but $(2) is empty, so all of the
*_LIBNAME variables are being set to "grass_". You can confirm this by
using the -p switch (e.g. "make -p -C lib/form"), which will print all
of the variable definitions.

FWIW, it works for me with make 3.81 (and presumably for everyone else
who has compiled it in the last month). My first guess would be an
issue with your version of make; which version are you using?

Same problem on grass.osgeo.org - no more possibility to
create binaries and the online 7 manual.

Right.

Confirmed.

I am on Fedora 4 (so old, but so far ok) with
make -v
GNU Make 3.80

I think that this should continue to work... GRASS will be used
on many "ancient" machines.

3.81 was released on 1st April 2006, so it's not exactly
bleeding-edge.

Having to support 3.80 would mean that we would have to get rid of the
loop, and instead have 68 copies of:

        FOO_LIBNAME = grass_foo
        ifneq ($(NEED_DEPS),)
        FOOLIB = -l$(FOO_LIBNAME) $(FOODEPS)
        else
        FOOLIB = -l$(FOO_LIBNAME)
        endif
        FOODEP = $(BASE_LIBDIR)/$(LIB_PREFIX)$(FOO_LIBNAME)$(LIB_SUFFIX)

(one for each of the 68 libraries).

[We can't just conditionalise the definitions of the *DEPS variables,
as they're used when building shared libraries.]

It isn't an issue for 6.x, but for 7.0 I don't think that it's
unreasonable to require a version of make less than 3.5 years old.

It's not like the compiler, where the version used has some effect
upon the resulting binaries, and may be tied to the version of
binutils and/or libc. People building on ancient systems can always
install[*] make 3.81 specifically for building GRASS 7.

[*] "install" is an exaggeration; make consists of the "gmake"
executable, the (optional) "make" symlink, and the documentation. You
can just compile it then run the not-installed executable directly.

This solution just works, I compiled everything with only an error in
r.in.wms but this is another problem.

Thanks,

Ok, that's true.

Alright, you have easily convinced me now :)

Suggestion: Add a test in configure for
make >= 3.81
?

Meanwhile I'll create a new make RPM for grass.osgeo.org.

For the record: After updating make to 3.81 the creation
of generic GRASS 7 Linux binaries and HTML manual is
possible again on a weekly base. I have triggered the
snapshot update, it has completed now:

http://grass.osgeo.org/grass70/manuals/html70_user/
http://grass.osgeo.org/grass70/binary/linux/snapshot/

We don't know which program will be used to actually build the source.
The "make" found in the path may be some ancient version or the
vendor's (non-GNU) make, but that doesn't matter if the user is going
to be using e.g. /path/to/gmake-3.81 to actually build GRASS.
