Subject: [PATCH] share/text.h: fix build failure against gcc-10
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
On gcc-10 (and gcc-9 -fno-common) build fails as:
|
|
|
|
```
|
|
cc .. -o neverball ...
|
|
ld: ball/st_save.o:(.bss+0x0):
|
|
multiple definition of `text_input'; share/text.o:(.bss+0x0): 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.
