Strange problem with nmake and Intel Fortran

[Arjen_Markus]

Hello,

I have run into a rather peculiar problem with nmake and ifort. I have a makefile to build a library and two programs. When I run nmake, all goed well except when building the programs. However, when I use exactly the same command via the command prompt, these steps succeed. Here is the output to the screen:

D:\flibs\tests\sqlite>nmake

I have tried to identify the difference via the option /watch:all, but apart from the names of temporary object files and the like, there is no difference that I can detect.

What can I do about this?

My guess is that your makefile happens to have a variable called LIB, which ends up being exported into the environment when the ifort compiler driver is invoked by nmake, and which then mucks up the search path for libraries.

Oh dear, spot on! I do define a macro LIB to take care of platform dependencies - I had not realised that this might interfere with the environment variables

Thanks, this makes sense.
