Subject: [PATCH 3/3] Drop superfluous global variable definitions
|
|
|
|
The only place where the EXTERN macro mechanism is used to define the
|
|
global variables 'portfd_is_socket', 'portfd_is_connected' and
|
|
'portfd_sock_addr' is minicom.c (by defining an empty EXTERN macro and
|
|
including the minicom.h header). The source file sysdep1_s.c already
|
|
defines these variables. The sysdep1_s.o object file is always linked
|
|
to minicom.o. Thus it is safe to drop the definitions from minicom.c
|
|
and only declare the variables in the minicom.h header.
|
|
|
|
This fixes linking with gcc 10 which uses -fno-common by default,
|
|
disallowing multiple global variable definitions.
