Summary:
SYMPTOMS
Using the CL driver that comes with Microsoft C versions 6.0, 6.0a,
and 6.0ax to invoke MASM versions 6.0 and 6.0a to assemble a .ASM
file specified on the CL compile line will result in an error
similar to one of the following:
error A2901: cannot run ML.EXE
-or-
Unknown option: /. Use /help for list of options
-or-
Assembling: NUL.asm
NUL.asm(0): error A2088: END directive required at end of file
CAUSE
The C online help for CL states that files that are listed on the
command line with a .ASM extension will automatically cause MASM to
be invoked. When this happens, CL.EXE invokes MASM.EXE. With MASM
5.1 or 5.1a, this will run the assembler.
However, with MASM 6.0 and 6.0a, MASM.EXE is a compatibility driver
for ML.EXE, which executes version 6.0 of the assembler. The
command-line switches and filename are not being passed correctly
from the CL.EXE to ML.EXE. This results in a variety of error
messages as shown above.
STATUS
Microsoft has confirmed this to be a problem in MASM versions 6.0
and 6.0a. We are researching this problem and will post new
information here as it becomes available.
