[GRASS5] GRASS 5.1: MacOSX compilation?

[Markus Neteler]

A followup:

it seems to be a problem of the libraries, not the modules.

file /Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/lib/libgrass_raster.dylib
/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/lib/libgrass_raster.dylib: Mach-O executable ppc

This is certainly wrong, obviously due to the use of
 gcc -dylib
instead of
 gcc -dynamiclib

(defined as: SHLIB_LD in aclocal.m4)

Changing this, I arrive at (tried with libgis):

[timonchiotwin:~/grass51exp/lib/gis] markus% make
gcc -L/sw/lib -L/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/lib
        -dynamiclib -flat_namespace -fno_common -undefined suppress
        -L/sw/lib
        -L/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/lib \
[...]

OBJ.powerpc-apple-darwin6.6/gisinit.o definition of common _CELL_NODATA (size 4)
/usr/bin/libtool: internal link edit command failed
make: *** [/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/lib/libgrass_gis.dylib] Error 1

The parameters I was guessing from PROJ4 which compiles on Mac OSX, but
PROJ4 is using 'libtool'.

Still in the dark,

 Markus
