How to complie driver with C and ASM code using WDK 6000?

Hi all.

I’m writing a driver with both C and ASM Code( because Inline asm can’t
access to IDTR ). My compling step is as following:

1 Complies asm code using MASM32 v8 to generate interrutprocess.obj file;

2 Add the .obj file to Source using macro TARGETLIBS;

3 run build -cZ

Then I get error:

interrutprocess.obj LNK2026: module unsafe for SAFESEH image;

error LNK1281: Unable to generate SAFESEH image.

I tried to complies ASM code with option /safeseh, but finally I get another
error:

interrutprocess.obj LNK1107: invalid or corrupt file: cannot read at 0xD8

Does anyone see this error?

Thank you for your reply

Usually I see this error when I do something like inadvertently try to
use the same file for input and output, or something like that, but I
don’t use BUILD. I’m not entirely sure what you mean by MASM32. If you
mean an old version of ML, then it is possible that you need to specify
the /coff switch to prevent it from defaulting to OMF.

The WDK includes a working version of MASM. You should integrate the build process of your .asm files into the BUILD.EXE build environment rather than creating object files outside the scope of the build environment and then linking to those .obj files. Using foreign versions of MASM is just as discouraged as using a different compiler than as ships with the WDK.

You may list .asm files as normal in a “SOURCES=” directive of a “SOURCES” file. The .asm files must be placed in a subdirectory named by the target architecture. For example, x64 .asm files are required to be in an “amd64” subdirectory and x86 .asm files are required to be an “i386” subdirectory.
