|
# NOTES
|
|
#
|
|
# I tried to force gmake to use the native shell for simplicity, by
|
|
# setting SHELL as below, but this didn't work reliably because of
|
|
# various case sensitivity niggles. Specifically, COMSPEC (which is in
|
|
# fact usually spelled ComSpec on NT, to make life difficult) typically
|
|
# references "cmd.exe" (on NT) when the file is actually called
|
|
# "CMD.EXE" on disk for hysterical raisons. As a result, GNU make
|
|
# thinks it doesn't exist (unless compiled with a switch to ignore
|
|
# case), and so doesn't change which shell it will invoke to execute
|
|
# commands.
|
|
#
|
|
# It would be possible, though very tedious using just gmake facilities,
|
|
# to convert the COMSPEC value to uppercase to solve this problem, but
|
|
# it isn't worth it. That is partly because, even when using the native
|
|
# shell, gmake tends to not be happy with backslashes in command
|
|
# strings. The obvious solution is to use forward slashes as much as
|
|
# possible, which can be made to work most of the time (putting
|
|
# filenames in quotes often helps), but there are still some internal
|
|
# cmd.exe commands like `del' and `copy' that won't work with them.
|
|
# Although it is possible to convert slashes to backslashes when
|
|
# necessary, gmake requires explicitly calling its subst function, which
|
|
# nmake does not understand). For this reason, it is simplest to
|
|
# mandate that rm and cp be available, so we can use Unix-format file
|
|
# names everywhere. (Fortunately both MS and GNU make, and the
|
|
# respective compilers, are happy with Unix-format names.)
|
|
#
|
|
# Since we cannot easily force the choice of a particular shell, we must
|
|
# make the effort to cope with whichever shell is being used.
|
|
# Fortunately, the only command we need to use that is shell specific is
|
|
# the testing of a file's existence for the purpose of working out when
|
|
# we are copying files to their original location. That particular
|
|
# requirement is abstracted easily enough.
|
|
#
|
|
# The only other problem area was the change of directory when running
|
|
# temacs to dump emacs.exe (where gmake doesn't support cd foo in any
|
|
# useful way), but that has been resolved by modifying the Windows
|
|
# unexec function slightly to not require the directory change while
|
|
# still allowing objects and binaries to be in subdirectories.
|
|
|
|
# This doesn't work.
