Estimated hours taken: 1 Some changes to the compiler require that a user trying to build and install a new version of the compiler from Mercury sources do the `mmake install' step from the stage 2 directory. This was not mentioned in the INSTALL_CVS; this change fixes that omission. INSTALL_CVS: Now runs a bootcheck by default and performs the `mmake install' from the stage 2 directory. Updated the instructions to tell the user how to install without the bootcheck, and the implications of doing this.

# INSTALL_CVS - installation instructions and installation script.
|
|
# This version is for use by Mercury developers after you have
|
|
# just checked the files out from the CVS archive.
|
|
# Note: you need a previous version of Mercury
|
|
# already installed (the CVS archive doesn't have all the necessary
|
|
# files for bootstrapping).
|
|
# You also need autoconf (and hence GNU m4) installed.
|
|
#
|
|
# Step 0. autoconf
|
|
#
|
|
# Step 1. ./configure
|
|
#
|
|
# Step 2. mmake depend
|
|
#
|
|
# Step 3. mmake
|
|
#
|
|
# Step 4. tools/bootcheck
|
|
#
|
|
# Step 5. cd stage2 && mmake install
|
|
#
|
|
# If you just want to do a `make' rather than a `make install',
|
|
# then comment out the `mmake install' line below.
|
|
#
|
|
# If you want to install without doing a boot check, then comment
|
|
# out the `tools/bootcheck' and `cd stage2' lines below. If the
|
|
# version of the compiler you checked out is buggy and you don't
|
|
# perform a boot check first, you risk installing a version of the
|
|
# compiler incapable of compiling itself. Make sure you have a
|
|
# fall-back plan if you do this.
|
|
# Note also that occasionally changes made to the compiler mean
|
|
# that installing from a stage 1 build will fail, even when the
|
|
# compiler is fine. In such cases the only way to install the
|
|
# compiler is from the stage 2 directory.
|
|
#
|
|
# If you don't want to do a parallel make, comment out the
|
|
# `parallel=-j3' line below.
|
|
|
|
parallel=-j3
