I am attempting to set up an nmake makefile to export our balsamiq mockup files to png files automatically, but I'm afraid I can't make heads nor tails of how to make a generic rule for doing so, without explicitly listing all the files I want exported.
This page details the command line syntax for exporting the files, and this page contains an example which looks like it contains a generic rule for .obj files to .exe files.
The makefile I have tried so far looks like this:
.bmml.png:
"C:\Program Files\Balsamiq Mockups\Balsamiq Mockups.exe" export $< $@
But this doesn't work.
If I simply run nmake (with some outdated png files), nmake just does this:
[C:\Temp] :nmake
Microsoft (R) Program Maintenance Utility Version 9.00.30729.01
Copyright (C) Microsoft Corporation. All rights reserved.
[C:\Temp] :
If I ask it to build one specific file, it does this:
[C:\Temp] :nmake "TestFile.png"
Microsoft (R) Program Maintenance Utility Version 9.00.30729.01
Copyright (C) Microsoft Corporation. All rights reserved.
NMAKE : fatal error U1073: don't know how to make '"TestFile.png"'
Stop.
[C:\Temp] :
Any nmake gurus out there that can set me straight?
An example makefile which simply makes .dat files from .txt files by copying them, to experiment with, looks like this:
.txt.dat:
copy $< $@
this does nothing as well, so clearly I'm not understanding how such generic rules work. Do I need to specify a goal above that somehow lists the files I want?
