Did you run upgrade.py?

Jay:

I appreciate your help.

I just updated via CVS to get all your latest changes, but I am still getting the error with non-unique match for _xmm.

See below:
…
msvcrt.lib

m3core.def : warning LNK4022: cannot find unique match for symbol '_xmm'
m3core.def : warning LNK4002: __xmm at 41f00000000000000000000000000000 defined in dtoa.obj
m3core.def : warning LNK4002: __xmm at 80000000000000008000000000000000 defined in dtoa.obj
m3core.def : error LNK2001: unresolved external symbol _xmm
m3core.lib : fatal error LNK1120: 1 unresolved externals

Can you point me in the right direction to solve this problem?

Thanks,
Randy Coleburn

This is fixed now too.

Dragisha had introduced heap corruption in FSWin32.m3 trying to improve Unicode support.

Hm. That leaves me with:

Not good.

I updated m3-sys/mklib to ignore these.

Let me know if there are any more problems.

Thanks,

No. There is no chance of this.

No. There is no chance of this either.

I forget how we generate the .def file but we need to exclude names "like" this -- that start _xmm at .

These are floating point constants for code that uses sse2.

You are targeting 32bit, right?

Still, I guess these might occur, with newer compilers.

I'll look into it.

We already have to code exclude the older forms of floating point constants.
