DOCERR: MASM 6.0 Makefile BELL.MAK Gives C1024 Compiler Error (71980)

SUMMARY

When NMAKE is run on the makefile BELL.MAK included with the sample programs in the Microsoft Macro Assembler (MASM) version 6.0, the following error is generated:

BELL.c(31): fatal error C1024: cannot open include file 'demo.h'

This error occurs because the makefile does not contain the correct directory location for the file DEMO.H.

Any of the following methods can be used to work around the C1024 error:

Copy the file DEMO.H from the \SAMPLES\DEMOS subdirectory to the \SAMPLES\TSR subdirectory. -or-
Copy the file DEMO.H from the \SAMPLES\DEMOS subdirectory to a directory specified by your INCLUDE environment variable. -or-
Use the /I assembler switch to specify the \SAMPLES\DEMO directory as an additional directory to search for include files. This can be done from inside the Programmer's WorkBench as follows:
1. Choose the Set Program List option from the Make menu.
2. Select BELL.MAK from the list of available files.
3. Choose C Compiler Options from the Options menu.
4. In the Additional Options field, enter the /I option with the path to the directory containing DEMO.H. For example:
  /IC:\MASM\SAMPLES\DEMOS

MORE INFORMATION

By default, BELL.MAK is installed in a subdirectory under MASM 6.00 called \SAMPLES\TSR. BELL.MAK should compile the file BELL.C and assemble the files INSTALL.ASM and HANDLERS.ASM. BELL.C includes the file DEMO.H, which is located in the \SAMPLES\DEMO subdirectory.

The C1024 error occurs because the compiler cannot find DEMO.H, since the compiler searches for include files only in the current directory or in the directory(s) pointed to by the INCLUDE environment variable.
