Cygwin & makefiles - not finding files in -I'd directory

This is a bit cryptic, but here's the info I have...

My Makefile looks something like:

Code:

INCDIR = -I~/HDKProjects/Hydrous2/WaveTools2/WaveTools/ \

        -I~/HDKProjects/MLInclude/ \

        -I~/HDKProjects/Hydrous2/OPs/Standalone



 # ....



%.o: %.C

        $(CC) $(OBJFLAGS) $(INCDIR) -DMAKING_DSO $(TAGINFO) $< $(OBJOUTPUT)$@



#.....

... there's more to it, but those are the important bits & what I'm currently trying to compile.

The first file it tries to compile has an include like so:

Code:

#include <SampledWave.h>

Where SampledWave.h is in ~/HDKProjects/Hydrous2/WaveTools2/WaveTools/

However, when I try to compile, I get a "fatal error, can not open included file 'SampledWave.h': No such file or directory."

I've checked that I have read permissions. I've copy/pasted all paths from the make file into cygwin to be sure there are no spelling/capitalization errors, I've tried removing the '~' & using the full path, I've tried with a space after the "-I" & without. I've tried putting a link to ~/HDKProjects/Hydrous2/WaveTools2/WaveTools/ in /usr/include & then changed the #include to be <foo/SampledWave.h>. Nothing seems to work.

If it helps, this is what the makefile spits out for the compile line:

Code:

c:\cygwin\home\BrianK_Labs\HDKProjects\Hydrous2\Vex\HT_Liquid.h(25) : fatal erro

r C1083: Cannot open include file: 'SampledWave.h': No such file or directory

ideas?

It's been a while, but could the cl compiler not like the UNIX style paths you give it for the include files?

I have not touched C for a while. I wonder if you have tried
#include "SampledWave.h"
or
#include "full path to SampledWave.h"

I remember that C compiler uses different algorithms to search for <xyz.h> than "xyz.h". (check the reference of cl)

That was it. Thanks!

In Makefile, instead of ~, you could use the HOME environment variable, i.e.

Code:

INCDIR = -I$HOME/HDKProjects/Hydrous2/WaveTools2/WaveTools/ \

        -I$HOME/HDKProjects/MLInclude/ \

        -I$HOME/HDKProjects/Hydrous2/OPs/Standalone

...

The expansion of '~' to equal your $HOME directory is a BASH feature and is not supported by 'make'.
Sometimes you may need to set LD_LIBRARY_PATH or, more to your case, C_INCLUDE_PATH when using Mingw32 or cygwin

I'm guessing you're speaking of cygwin? '~' in makefiles works fine on my Debian, Ubuntu, and Suse machines.

Either way, using the full path (i.e. c:/cygwin/home/...) or $HOME works, so I'm all set.
