Edit report at https://bugs.php.net/bug.php?id=80176&edit=1 ID: 80176 Updated by: cmb@php.net Reported by: php-bugs-2020 at ryandesign dot com Summary: configure script fails to include required headers Status: Open Type: Bug Package: *General Issues Operating System: macOS 10.15.6 PHP Version: 7.4.11 Block user comment: N Private report: N New Comment: > main/reentrancy.c:125:23: error: too few arguments to function call, expected 3, have 2 > readdir_r(dirp, entry); That has already been reported as bug #80171. Previous Comments: ------------------------------------------------------------------------ [2020-10-02 16:32:14] php-bugs-2020 at ryandesign dot com Description: ------------ php fails to build on macOS with Xcode 12. New in Xcode 12 is that implicitly declaring functions is now an error; before it was just a warning. Many of the configure script tests fail to include all of the required headers, leading to those tests failing to correctly identify the system's capabilities, such as: conftest.c:103:5: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration] exit(2); ^ conftest.c:103:5: note: include the header <stdlib.h> or explicitly provide a declaration for 'exit' conftest.c:111:3: error: implicit declaration of function 'unlink' is invalid in C99 [-Werror,-Wimplicit-function-declaration] unlink(filename); ^ The build later fails, for example with this error: main/reentrancy.c:125:23: error: too few arguments to function call, expected 3, have 2 readdir_r(dirp, entry); ~~~~~~~~~ ^ /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/dirent.h:110:1: note: 'readdir_r' declared here int readdir_r(DIR *, struct dirent *, struct dirent **) __DARWIN_INODE64(readdir_r); ^ This was reported to MacPorts against php73 here: https://trac.macports.org/ticket/60988 and against php72 here: https://trac.macports.org/ticket/61168 but it also affects php74 and presumably all other php versions. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80176&edit=1
