For the load directive, the docs say ...
The initializing function will be provided the file name and line
number of the invocation of the 'load' operation. It should return a
value of type 'int', which must be '0' on failure and non-'0' on
success. If the return value is '-1', then GNU make will _not_
attempt
to rebuild the object file ...
However, near the end of load.c (load_file), I see ...
/* Invoke the symbol. */
r = (*symp) (flocp);
/* If it succeeded, add the load file to the loaded variable. */
if (r > 0)
do_variable_definition (flocp, ".LOADED", *ldname, o_default,
f_append, 0);
The test for success should be (r != 0). If the return value is -1,
then it will never be appended to .LOADED.
The docs also say ...
The file OBJECT-FILE is dynamically loaded by GNU 'make'. If
OBJECT-FILE does not include a directory path then it is first looked
for in the current directory. If it is not found there, or a
directory
path is included, then system-specific paths will be searched.
If the OBJECT-FILE is found in one of the system-specific paths, does
it ever make sense to attempt to remake it, since the full pathname
isn't known? The rebuilt OBJECT-FILE could also wind up in a different
place.
I wonder if the test for "do _not_ attempt to rebuild" should be < 0,
rather than == -1.
Thanks!
