I am using cmake.
I tried
-fatal-warnings
(mentioned here )
-fatal_warnings
(which is mentioned with man ld
)
Are those supposed to be used with -W
?
I would like all linker warnings across the whole project to be an error.
The warning I get is:
ld: warning: ignoring file libvst2sdk.a, building for macOS-arm64 but attempting to link with file built for unknown-unsupported file format ( 0x21 0x3C 0x61 0x72 0x63 0x68 0x3E 0x0A 0x23 0x31 0x2F 0x32 0x30 0x20 0x20 0x20 )
-Werror is a compiling flag that treat warnings as errors, and it's not linker flag.
-Wl,--fatal-warnings
-Wl means pass options to linker.
and here is pass 3 options to linker seperated by space:
-Wl,--build-id -Wl,--warn-shared-textrel -Wl,--fatal-warnings
or seperated by comma
-Wl,--build-id,--warn-shared-textrel,--fatal-warnings
