Subject: [PATCH] gcc.specs: drop --fatal-warnings from linker options (ia64
|
|
compatibility)
|
|
|
|
```
|
|
$ LANG=C make HOSTCC=x86_64-pc-linux-gnu-gcc CC=ia64-unknown-linux-gnu-gcc HOST_ARCH=ia64
|
|
ia64-unknown-linux-gnu-gcc ... \
|
|
-o libefivar.so ...
|
|
/usr/libexec/gcc/ia64-unknown-linux-gnu/ld: warning: -z relro ignored
|
|
collect2: error: ld returned 1 exit status
|
|
make[1]: *** [/home/slyfox/dev/git/efivar/src/include/rules.mk:32: libefivar.so] Error 1
|
|
```
|
|
|
|
ia64 (and a few others) binutils target does not support '-z relro' and always
|
|
issues a warning. --fatal-warnings spec option turns the build into always failing one.
|
|
|
|
The change drops `--fatal-warnings` options from gcc.spec entirely.
