[m-users.] Building the ODBC library fails

[Volker Wysk]

Hi!

I've downloaded the latest ROTD source distribution and tried to build the
ODBC library. I'm using the stable release 20.06.1:


desktop /usr/local/src/mercury-srcdist-rotd-2022-01-13/extras/odbc $ mmc --
make libodbc.depend
desktop /usr/local/src/mercury-srcdist-rotd-2022-01-13/extras/odbc $ mmc --
make libodbc
Making Mercury/int3s/odbc.int3
Making Mercury/ints/odbc.int
Making Mercury/cs/odbc.c
odbc.m:101: In predicate `transaction'/7:
odbc.m:101:   warning: unresolved polymorphism.
odbc.m:101:   The variable with an unbound type was:
odbc.m:101:     V_40: exception.exception_result(T)
odbc.m:101:   The unbound type variable will be implicitly bound to the
builtin
odbc.m:101:   type `void'.
For more information, recompile with `-E'.

** Error making `Mercury/os/odbc.o'.		


It's the same with the "extras/odbc" in the 20.06.1 source distribution. 

It works for "odbc_test" with "mmake depend ; mmake odbc_test". But "mmake"
results in:


desktop /usr/local/src/mercury/extras/odbc $ LANG=C mmake
/tmp/mmake.92SAYH:895: warning: undefined variable
'MMAKE_USE_SUBDIRS_EXPLICIT'
/tmp/mmake.92SAYH:919: warning: undefined variable
'MMAKE_USE_SUBDIRS_EXPLICIT'
make: Nothing to be done for 'default_target'.


It's the same for "mmake libodbc".


Cheers,
Volker
