Itanium linker

This sounds so silly but I don't understand why the following link command fails on Itanium.

$ libr/lis/fu/names/only=vm$$_malloc [ndm.3301dev.ndm.images]NDM3301.OLB/lo

Please disregard this message, I know what is wrong.

Malleka,
for our collective education can you say what the problem was ?

Re: Ian

Me thinks that the module VM$$_MALLOC, defines the functions VM$$_CFREE and VM$$_FREE, but not the function VM$$_MALLOC itself (just guessing from the info provided by Malleka).

Kris (aka Qkcl)

Ian,

The problem was that the routines in VSS_MALLOC had each coditional compilation for VAX and Alpha. It was being updated by another person to include the ia64. I thought that this had already been done and tried to link but the object modules were apparently empty.
