I have put the current version of the source code of the full GRADE
environment (GRED-1.3.0 + DDBG-1.0a + grp2c-0.27.0) on our ftp server:
ftp://sun60.mszki.kfki.hu/pub/grade-dist.tar.gz 

The new version of GRED supports the PVM code generation on cluster of
workstations.  The 'Generate C' and 'Build Exe' menu items have been
omitted from the 'Tools' pulldown menu and a new puldown menu -- 'Compile'
-- has been created instead. 'Compile' menu can be used to generate PVM
executables from the GRAPNEL code on different hosts. 

In order to compile and run GRAPNEL processes on different hosts, you must
have a PVM hostfile before starting the editor and you must install a part
of the GRADE environment on every remote hosts with the "make remote"
command. The name of the PVM hostfile can be defined in the 'grade'
start-up script and the hostfile must contain the 'ep' option for each
host. 


The following two (known) problems [can] occur during the installation:

1. In the directory grp2c-0.27.0/parser.src:

ld: warning: option -o appears more than once, first setting taken
ld: fatal: file libparser.so.0.27: cannot open file; errno=2
ld: fatal: File processing errors.  No output written to 
libparser.so.0.27.0

Solution : modify the following line in the config.cache file located in
directory grp2c-0.27.0:

grp2c_cv_CXXshared=${grp2c_cv_CXXshared='no'}
(The original value is 'yes'). Then execute 'make' again (in the root dir
of GRADE). 

[2.] In the directory grp2c-0.27.0/grapnel.src/pvm.src:

grapnel_p.c:23: pg_proto.h: No such file or directory
make[3]: *** [grapnel_p.o] Error 1

Solution: modify the following line in the Makefile located in directory
grp2c-0.27.0/grapnel.src/pvm.src:

with_pg         = no
(The original value is 'yes'). Then execute 'make grade' (in the root dir
of GRADE)                                    ^^^^^^^^^^
(Simple 'make' overwrites all Makefiles, that is why 'make grade' is
needed!)
