Subject: [PATCH] meson: drop misplaced -Wl,--undefined argument
|
|
|
4bff0a |
|
|
|
4bff0a |
Ld's man page says the following:
|
|
|
4bff0a |
|
|
|
4bff0a |
-u symbol
|
|
|
4bff0a |
--undefined=symbol
|
|
|
4bff0a |
|
|
|
4bff0a |
Force symbol to be entered in the output file as an undefined symbol. Doing
|
|
|
4bff0a |
this may, for example, trigger linking of additional modules from standard
|
|
|
4bff0a |
libraries. -u may be repeated with different option arguments to enter
|
|
|
4bff0a |
additional undefined symbols. This option is equivalent to the "EXTERN"
|
|
|
4bff0a |
linker script command.
|
|
|
4bff0a |
|
|
|
4bff0a |
If this option is being used to force additional modules to be pulled into
|
|
|
4bff0a |
the link, and if it is an error for the symbol to remain undefined, then the
|
|
|
4bff0a |
option --require-defined should be used instead.
|
|
|
4bff0a |
|
|
|
4bff0a |
This would imply that it always requires an argument, which this does not
|
|
|
4bff0a |
pass. Thus it will grab the next argument on the command line as its
|
|
|
4bff0a |
argument. Before it took one of the many -lrt args (presumably) and now it
|
|
|
4bff0a |
grabs something other random linker argument and things break.

[zj: this line was added in the first version of the meson configuration back
|
|
|
4bff0a |
in 5c23128daba7236a6080383b2a5649033cfef85c. AFAICT, this was a mistake. No
|
|
|
4bff0a |
such flag appeared in Makefile.am at the time.]
