The signal definitions of musl and gdb collide
|
||
|
|
|
||
|
|
The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
|
||
|
|
defines it in signal.h which collides.
|
||
|
|
Kernel 4.14 misses the definitions of struct user_sve_header so we still
|
||
|
|
have to use the aarch64-sve-linux-sigcontext.h header file which also
|
||
|
|
provides that and make sure aarch64-sve-linux-sigcontext.h does not
|
||
|
|
provide the same headers as the kernel or musl.
