# limitations we cannot issue a link command with all object filenames

|
# to be linked, and specify this list-file with @listfile on the command-line.
|

|
|
|
#
|

# the difficult part is doing this in a flexible way; we don't want to
|
|

|
# hard-code the to-be-linked object filenames in a file, but instead
|
|
|
|

# want to dynamically create a file containing a list of all object filenames
|

|
# within the $XXX_OBJECTS makefile variables. to do this, we use side-effect
|
|
|
|
|
# variables.
|
|
|
|
|
#
|
|
|
|
|
# idea: when these variables are EVALUATED (i.e. later during rule execution,
|
|
|
|
|
# not now during variable definition), they cause a SIDE EFFECT which creates
|
|
|
|
|
# a file with the list of all ODE object files. why the chicanery??? because
|
|
|
|
|
# if we have a command-line length limitation, no SINGLE command we issue will
|
|
|
|
|
# be able to create a file containing all object files to be linked
|
|
|
|
|
# (because that command itself would need to include all filenames, making
|
|
|
|
|
# it too long to be executed). instead, we must use the gnu-make "foreach"
|
|
|
|
|
# function, combined - probably in an unintended way - with the "shell"
|
|
|
|
|
# function. this is probably unintended because we are not using the "shell"
|
|
|
|
|
# function to return a string value for variable evaluation, but are instead
|
|
|
|
|
# using the "shell" function to cause a side effect (appending of each filename
|
|
|
|
|
# to the filename-list-file).
|
|
|
|
|
#
|
|
|
|
|
# one possible snag is that, forbidding use of any external EXE utilities and
|
|
|
|
|
# relying only on the facilities provided by the outdated 16-bit operating
|
|
|
|
|
# system, there is no way to issue a SERIES of commands which append text to
|
|
|
|
|
# the end of a file WITHOUT adding newlines. therefore, the list of to-be-
|
|
|
|
|
# linked object files is separated by newlines in the list file. fortunately,
|
|
|
|
|
# the linker utility for this outdated 16-bit operating system accepts
|
|
|
|
|
# filenames on separate lines in the list file.
|
|
