package/unixodbc/0001-fix-nopthread.patch

   1 Fix pthread detection
   2
   3 configure.in always calls AC_CHECK_COMP_OPT(pthread) which succeeds with the
   4 toolchain used although it does not contain thread support:
   5
   6 checking for mutex_lock in -lthread ... no
   7 checking for pthread_mutex_lock in -lpthread... no
   8 checking for pthread_mutex_lock in -lc... no
   9 checking if compiler accepts -pthread... yes
  10 checking for pthread_mutex_lock in -lc... no
  11 checking for pthread_mutex_lock in -lpthread... no
  12
  13 This positive configure check leads to
  14
  15     CFLAGS="$CFLAGS -pthread"
  16
  17 in ./configure, line 15757 which causes a compilation bug

  23 This patch disables the freebsd-only code path. Patching configure directly
  24 prevents the need for autoreconf.
