[GRASS-dev] make on SMP [was: GRASS 6.3.0 release preparation]

[Soeren Gebbert]

Looks like the gpde library causes some problems. :/
I guess this is related to the Makefile. The gpde lib Makefile copies the
N_pde.h
header file into the build include directory before compiling:

MODULE_TOPDIR = ../..

EXTRA_LIBS=$(GISLIB) $(G3DLIB)
LIB_NAME = $(GPDE_LIBNAME)

include $(MODULE_TOPDIR)/include/Make/Lib.make
include $(MODULE_TOPDIR)/include/Make/Doxygen.make

default: headers lib

headers:
        for file in ./N_*.h ; do $(INSTALL_DATA) $$file
$(GISBASE)/include/grass/ ; done

lib: headers

#doxygen:
DOXNAME=gpde


I don't know why this is not working on a smp machine?
Are you using NFS? Maybe there is a delay while copying the header?
Sorry, i cant help much in this case, my Makefile knowledge is very limited.


Best  regards
Soeren
