MIDL Compiler error: MIDL

Question

When I use MIDL to compile a IDL file to .h and .c, I get a error said:

midl : command line error MIDL1004 : cannot execute C preprocessor cl.exe.

Please kindly help me, I do not know why.

The MIDL compiler which I use is part of VC++ 6.0.

Thanks.

It seems your environment is not correctly set. Try calling vcvars32 before compiling.
