With our current gnulib copy, the mechanism for +deciding whether to use the system's 'getcwd' or gnulib's version is +too simplistic and pessimistic, so when cross-compiling we always end +up using gnulib's version, which has a limitation: it cannot handle +the situation when the parent directory doesn't have read permissions. + +The solution is to backport the following gnulib commit: + + commit a96d2e67052c879b1bcc5bc461722beac75fc372 + Author: Bruno Haible <bruno@clisp.org> + Date: Thu Aug 23 21:13:19 2018 +0200 + + getcwd: Add cross-compilation guesses. + +gdb/ChangeLog: +2018-09-10 Sergio Durigan Junior <sergiodj@redhat.com> + + PR gdb/23555 + PR gdb/23558 + * gnulib/import/m4/getcwd-path-max.m4: Add cross-compilation + guesses. +--- + gdb/gnulib/import/m4/getcwd-path-max.m4 | 20 ++++++++++++++++---- + 1 file changed, 16 insertions(+), 4 deletions(-) + +diff --git a/gdb/gnulib/import/m4/getcwd-path-max.m4 b/gdb/gnulib/import/m4/getcwd-path-max.m4 +index 2531ccff65c..90bbc77dea1 100644 +--- a/gdb/gnulib/import/m4/getcwd-path-max.m4 ++++ b/gdb/gnulib/import/m4/getcwd-path-max.m4 +@@ -209,9 +209,21 @@ main () + 32) gl_cv_func_getcwd_path_max='yes, but with shorter paths';; + *) gl_cv_func_getcwd_path_max=no;; + esac], +- [case "$host_os" in +- aix*) gl_cv_func_getcwd_path_max='no, it has the AIX bug';; +- *) gl_cv_func_getcwd_path_max=no;; +- esac]) ++ [# Cross-compilation guesses: ++ case "$host_os" in ++ aix*) # On AIX, it has the AIX bug. ++ gl_cv_func_getcwd_path_max='no, it has the AIX bug' ;; ++ gnu*) # On Hurd, it is 'yes'. ++ gl_cv_func_getcwd_path_max=yes ;; ++ linux* | kfreebsd*) ++ # On older Linux+glibc it's 'no, but it is partly working', ++ # on newer Linux+glibc it's 'yes'. ++ # On Linux+musl libc, it's 'no, but it is partly working'. ++ # On kFreeBSD+glibc, it's 'no, but it is partly working'. ++ gl_cv_func_getcwd_path_max='no, but it is partly working' ;; ++ *) # If we don't know, assume the worst. ++ gl_cv_func_getcwd_path_max=no ;; ++ esac ++ ]) + ]) + ]) +-- +2.19.0 + |
