Compiling Liquid for Maya 5 and Pixie - HELP!

[kennez]

I am trying to compile the latest version of Liquid by following the instructions on the LiquidWiki. I have installed all of the required software (VCToolkit, etc), and have followed all of the instructions TO THE LETTER, but when I type 
make release, I get the following error message:

test was unexpected at this time. 
make: *** [release] Error 255

Any ideas on the problem here? Is it an issue with the makefile?

I really want to build Liquid against Pixie, and my other Renderman renderers, in order to test them all against the same scene, but currently I only have Liquid working with Aqsis, and I didn't compile that myself.

I am using Maya 5 on Windows XP. All of the latest compiled vesions of Liquid I have seen only work with Maya 6 or higher. Please help me.

Looking at the makefiles which are current in CVS, the environment variable MAYA_LOCATION may need to be defined to point at the Maya install location (surprise surprise).

If that doesn't work, make sure you're running gnu make (type 'which make' - it should report something under cygwin, 'make --version' may also give useful info).  Also make sure you're doing this from inside the cygwin shell - I think that's how it's supposed to work.  I'm not on Windows here, but folks who are I seem to remember build under cygwin.

Failing all the above, run make as

make -d release

may give useful debug info about which rules are being considered, and may help track down the problem.

Cheers

Right, I've managed to get past that error message, but now I am having a problem with setting MAYA_LOCATION in the makefile. I have set the path to the exact location of Maya on my system, but I am getting the following messages:

sh: line 0: test: c:/program: binary operator expected
sh: line 0: test: c:/Program\: binary operator expected
c:/Program \Files/AliasWavefront/Maya5.0 does not seem to exists. Please set MAYA_LOCATION to a correct value.
make:*** [release] Error 1

Please note that I have tried the slashes in all sorts of combinations of both / and \, I have enclosed the location of the Maya folder in "", and I have checked the location of the Maya folder. I have also used a \ to designate the space in the path, as the CYGWin shell does when changing directories.

The location of Maya on my system is C:\Program Files\AliasWavefront\Maya5.0
3Delight is located at C:\Program Files\3Delight
Aqsis is located at C:\Program Files\Aqsis
Pixie is located at C:\Program Files\Pixie

Please let me know what I am doing wrong.

I have also verified that I am using the current version of make.exe

Cheers,

Hi Malcolm,

Cygwin, being a linux-on-windows environment needs unix-style paths.  For some reason that escapes me, it doesn't have a mapping for c:\blah, but rather uses /cygdrive/c/blah.  I think things should work if you set

MAYA_LOCATION=/cygdrive/c/Program \Files/AliasWavefront/Maya5.0

but sometimes spaces in the paths can screw things up - so you may still need to quote the string in various ways as well. 

The same goes for LIQRMAN. 

Hope that helps

George

Thanks George,

I managed to get the makefile working, but I am now getting compiler errors and warnings.

From the semester that I did in C++, I know that warnings can be ignored (in general). The warning I get is:

maya/MTypes.h (85): warning C4005: 'MAYA_API_VERSION' : macro redefinition

I also get a similar warning for liqIOStream.h(9). I am assuming that this is because I am compiling against Maya 5. Can I just ignore this warning?
Another warning I get is from the file liqRenderScript.h(371). The message is;

warning c4002: too many actual parameters for macro 'LIQDEBUGPRINTF'

Can I ignore this one?

I am also getting 4 errors. These are all identical descriptions, and are from two Liquid files: liqRibNode.h(185), and liqRibTranslator.h(270)m (272) and (274). The error message for all of these errors is:

error c2639: compiler generated default constructor required by unnamed class.

Sorry to keep bothering you with this. I am really not much of a programmer. The only programs I have written are simple command line apps that take a number and convert it (and similar things), and these were written in C. I have not done much C++ at all.

Cheers,
Malcolm

It looks like the MString class is undefined.  I don't have 5.0 or 5.0.1 here to test with, but I'd try adding include lines like

#include <maya/MString.h>

to the to top of files you have problems with - though that should be pulled in from liquid.h.  I think the warnings can be ignored - but that may come back to bite me.

This may be a compiler version issue.  Any guys out there who've compiled recently under Windows ?

Sorry I can't be more use

George
