Mingw lacks fsync, but gnulib provides that. Meanwhile, gnulib does not (yet) provide fdatasync, so this is a quick hack to fake that function on MacOS X; we can revert this configure change once gnulib gives us a real module. * bootstrap.conf (gnulib_modules): Add fsync. * configure.ac (AC_CHECK_FUNCS_ONCE): Check for fdatasync, and fake it with fsync when not present. --- I've tested that this is a no-op on Linux, but would appreciate someone with a MacOS setup to quickly test that it fixes the build there. bootstrap.conf | 1 + configure.ac | 5 ++++- 2 files changed, 5 insertions(+), 1 deletions(-) diff --git a/bootstrap.conf b/bootstrap.conf index 94af051..e609ba8 100644 --- a/bootstrap.conf +++ b/bootstrap.conf @@ -42,6 +42,7 @@ fcntl fcntl-h ffs fnmatch +fsync func getaddrinfo getcwd-lgpl diff --git a/configure.ac b/configure.ac index 5e3539f..611a141 100644 --- a/configure.ac +++ b/configure.ac @@ -126,9 +126,12 @@ AC_CHECK_SIZEOF([long]) dnl Availability of various common functions (non-fatal if missing), dnl and various less common threadsafe functions -AC_CHECK_FUNCS_ONCE([cfmakeraw geteuid getgid getgrnam_r getmntent_r \ +AC_CHECK_FUNCS_ONCE([cfmakeraw fdatasync geteuid getgid getgrnam_r getmntent_r \ getpwuid_r getuid initgroups kill mmap posix_fallocate posix_memalign \ regexec sched_getaffinity]) +if test $ac_cv_func_fdatasync = no; then + AC_DEFINE([fdatasync], [fsync], [Define to fsync if you lack fdatasync]) +fi dnl Availability of pthread functions (if missing, win32 threading is dnl assumed).
