Subject: [PATCH] squashfs-tools: fix build failure against gcc-10
|
||
|
|
MIME-Version: 1.0

On gcc-10 (and gcc-9 -fno-common) build fails as:
|
||
|
|
|
||
|
|
```
|
||
|
|
cc ... -o mksquashfs
|
||
|
|
ld: read_fs.o:(.bss+0x0):
|
||
|
|
multiple definition of `fwriter_buffer'; mksquashfs.o:(.bss+0x400c90): first defined here
|
||
|
|
ld: read_fs.o:(.bss+0x8):
|
||
|
|
multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400c98): first defined here
|
||
|
|
```
|
||
|
|
|
||
|
|
gcc-10 will change the default from -fcommon to fno-common:
|
||
|
|
https://gcc.gnu.org/PR85678.
|
||
|
|
|
||
|
|
The error also happens if CFLAGS=-fno-common passed explicitly.
