Re: Troubles with GNUstep Make

[Nicola Pero]

Hi Torli

make sure your new GNUmakefile looks like

include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = WriteStr2File
WriteStr2File_OBJC_FILES = source.m
include $(GNUSTEP_MAKEFILES)/tool.make

(note how you have to replace LogTest twice) ;-)

If you don't replace the second instance of 'LogTest', gnustep-make  
won't find any files to link
for your tool, and so it will create a new tool from zero object  
files.  Then, the main() function
will be missing ;-)

I know it can be confusing at first - the idea is that TOOL_NAME  
provides the list of tools to compile,
and then, for each of them, you need a xxx_OBJC_FILES variable listing  
the files belonging to that
tool.

Hope this clarifies things :-)

Thanks and good luck
