Q64028: Changing Directories in Make Files Not Supported by NMK.COM
Article: Q64028 Product(s): See article Version(s): 1.11 Operating System(s): MS-DOS Keyword(s): ENDUSER | buglist1.11 S_QUICKC S_C | mspl13_basic Last Modified: 31-AUG-1990 Using a command to change directories in a make file will cause unexpected results with NMK.COM version 1.11. This is a side effect of a problem with NMAKE.EXE where directory changes within make files are executed while processing the make file, and the current directory is not reset upon exit. NMK spawns NMAKE to do its processing. While NMAKE is processing, if it sees a change drive/directory command, it must make the change to finish processing the make file. The problem is that it doesn't reset the drive when it is through processing. This causes NMK, when control is returned to it, to spawn the actual commands from the final drive/directory, rather than where it was originally invoked. The make file below, if run from Drive D, will demonstrate the problem. It works properly with NMAKE.EXE but not with NMK.COM. all: cded.exe cded.exe: cded.obj c:\ copy cded.obj cded.exe cded.obj: cded.mak copy cded.mak c:\cded.obj To work around the problem, add a line at the end of each place block where you change the drive/directory to the original one (if known). For example, change the above make file to the following: all: cded.exe cded.exe: cded.obj c:\ copy cded.obj cded.exe d: cded.obj: cded.mak copy cded.mak c:\cded.obj
