Testing GNU gettext's portability on Slackware 13, I get a compilation error:
file-has-acl.c: In function 'file_has_acl': file-has-acl.c:216:30: error: 'XATTR_NAME_POSIX_ACL_ACCESS' undeclared (first use in this function) file-has-acl.c:216:30: note: each undeclared identifier is reported only once for each function it appears in file-has-acl.c:218:34: error: 'XATTR_NAME_POSIX_ACL_DEFAULT' undeclared (first use in this function) make[6]: *** [file-has-acl.o] Error 1 The cause is that on 2023-05-12, the explicit check for XATTR_NAME_POSIX_ACL_ACCESS and XATTR_NAME_POSIX_ACL_DEFAULT was removed from m4/acl.m4. Slackware 13 (with glibc 2.13 and Linux 2.6.37) does not have these macros. So we have to provide a fallback, like it was done in 2015. 2023-06-05 Bruno Haible <[email protected]> file-has-acl: Fix compilation error on Slackware 13 (regr. 2023-05-12). * lib/file-has-acl.c (XATTR_NAME_POSIX_ACL_ACCESS, XATTR_NAME_POSIX_ACL_DEFAULT): Add fallback definitions. diff --git a/lib/file-has-acl.c b/lib/file-has-acl.c index 13f08c3055..3eeaf9c57d 100644 --- a/lib/file-has-acl.c +++ b/lib/file-has-acl.c @@ -40,6 +40,12 @@ # ifndef XATTR_NAME_NFSV4_ACL # define XATTR_NAME_NFSV4_ACL "system.nfs4_acl" # endif +# ifndef XATTR_NAME_POSIX_ACL_ACCESS +# define XATTR_NAME_POSIX_ACL_ACCESS "system.posix_acl_access" +# endif +# ifndef XATTR_NAME_POSIX_ACL_DEFAULT +# define XATTR_NAME_POSIX_ACL_DEFAULT "system.posix_acl_default" +# endif enum { /* ACE4_ACCESS_ALLOWED_ACE_TYPE = 0x00000000, */
