DescriptionMPS DLL link error: mps_arena_vm_growth is not exported

RHSK 2008-09-30
An MPS client that uses mps_arena_vm_growth() and links with the DLL
will fail to link. A typical error message is:
  error LNK2019: unresolved external symbol _mps_arena_vm_growth

See [1].

The mps_arena_vm_growth symbol is not exported from the MPS DLL;
this can be checked with "dumpbin /exports" on Windows.
AnalysisRHSK 2008-09-30
The list of DLL exports is in the w3gen.def file. This file is the
output from, which must be run manually.

When mps_arena_vm_growth() was added, this was not done, so it is
not listed in w3gen.def.

However, does not seem to work any more -- see job001255.

Should I fix No, it's not worth it. The addition of
mps_arena_vm_growth() is the first change since was
written (four years ago), and it's trivial to hand-edit w3gen.def.

So: do it by hand, and edit the "do not edit" comments to refer to
this decision. Check with "dumpbin /exports".

Note: there may be other problems with the DLL; see [2].
