The emulator is by default not built with thread support in the open
source release. In order to enable thread support one is supposed to
pass the "--enable-threads" argument to the configure script; but, due
to a bug this doesn't work. One can easily bypass this bug, though.
Do the following to build the open source release with thread support:
# Set the ERL_TOP environment variable to the absolute path of the
# top level directory
./configure --enable-threads $MY_OTHER_CONFIG_ARGS
cd $ERL_TOP/erts/autoconf # These steps
./configure --enable-threads $MY_OTHER_CONFIG_ARGS # bypass the
cd $ERL_TOP # bug.
If you succeeded "[threads]" should pop up on the first line in the
This bug will be fixed in the next patch to r7b01.
