Citeren Frédéric Bohé <[email protected]>:
Thanks for the clarification.
I just tried to compile and I have an error on this line, not sure how
to fix that.
common.c: In function 'confpath':
common.c:443:2: error: initializer element is not constant
common.c: In function 'dflt_statepath':
common.c:454:2: error: initializer element is not constant
I stand corrected. In order for this to work, the initializer must be
known at compile time (it should be a constant, since it is filled in
by the compiler and not at runtime). So instead of
static const char *path = getfullpath(PATH_ETC);
this should be split in
static const char *path = NULL;
if (path == NULL) {
path = getfullpath(PATH_ETC);
}
This will assign 'NULL' to 'path' at compile time and at runtime, will
try to read the path as long as it stays 'NULL'. This means that it
will only be assigned a value the first time this is executed.
Best regards, Arjen
