Subject: [PATCH] lv2: Make it build with -fno-common
|
||
|
|
|
||
|
|
GCC 10 defaults to -fno-common. This means that global variables shared
|
||
|
|
across multiple translation units should be declared as 'extern' in
|
||
|
|
header files and defined in exactly one C file. See:
|
||
|
|
https://gcc.gnu.org/gcc-10/porting_to.html
|
||
|
|
|
||
|
|
