First you have to make certain that your VMS-system has GNV version
1.5-6 loaded including bash 1.11. See this page.
for build instruction of bash 1.11.
Make certain that you have the following statements in your
login.com:
$! start gnv
$ @GNU:[lib]GNV_SETUP.COM
$!
$! setup tools
$ set proc/parse_style=extended
$ set process /case_lookup=(blind)
$ define/job decc$pipe_buffer_size 65000
$
$
$ scratch = f$trnlnm("sys$login") - "]" + ".temp]"
$ define/job sys$scratch 'scratch'
$
make a .bashrc in your login directory with at least
the following statements:
# .bashrc
#
PATH=$PATH:/usr/bin:/usr/local/bin
export PATH
export GNV_DISABLE_DCL_FALLBACK=1
After you have a working build environment, you can fetch
the sourcefile of bc 1.06 from this location:
http://ftp.gnu.org/pub/gnu/bc/bc-1.06.tar.gz
After you have copied this file to your working directory,
you can start the build of bc.
