Hello,
I get this:
pkcs15-iasecc.c: In function ‘iasecc_file_convert_acls’:
pkcs15-iasecc.c:312: warning: initialization discards qualifiers from
pointer target type
The problem is the line:
struct sc_acl_entry *acl = sc_file_get_acl_entry(file, ii);
If I change it to:
const struct sc_acl_entry *acl = sc_file_get_acl_entry(file,
ii);
I then get errors:
pkcs15-iasecc.c: In function ‘iasecc_file_convert_acls’:
pkcs15-iasecc.c:320: error: assignment of read-only location
pkcs15-iasecc.c:321: error: assignment of read-only location
pkcs15-iasecc.c:324: error: assignment of read-only location
pkcs15-iasecc.c:325: error: assignment of read-only location
This is because the iasecc_file_convert_acls() function _does_ change
the (const) structure returned by sc_file_get_acl_entry().
Complete function:
...
I don't know what is the proper way to fix this.
Remove 'cost' qualifier from the function prototype, like in attachment ?
By
Kind wishes,
Viktor.
