Re: Compiling OpenShadingLanguage under Windows


wormszer <worm...@...>
 

I too have been trying to build under windows and ran across the same
problem with the t variable.
Assuming gcc allows it for some reason, by default is_closure() is
false so that is what i set it too.

I am having trouble with some includes particulary
#include <unistd.h>

I have one error in oslquery a missing R_OK which is defined i believe
through this file.
I can dig it up and add it but I think i will run into more problems
later on in the other projects.

I am also getting a hash_map error when building oslcomp.

What version of flex and bison are you using? I had found a gnuwin32
builds of both but flex was pretty out of date.
I have installed cygwin to use the latest versions from there to run
flex and bison. Which generates files that have better includes
<iostream> vs <iostream.h> etc.

Hopefully we can get this figured out.
I am using visual studio 2008 as well. I just realized i might not
have sp1. I will update and see if that helps at all.

Thanks
Jeremy

Hi Chris,

Thank you very much for your reply. It works!

Here comes the next problem compiling the "osllex.cpp" file generated
by flex from "osllex.l" :-(

D:/Src/OpenShadingLanguage/src/liboslcomp/osllex.l(118) : error C2065:
'osllloc' : undeclared identifier

Here is the corresponding cpp code:

#define yylloc osllloc

void preprocess (const char *yytext);

// Macro that sets the yylloc line variables to the current parse
line.
#define SETLINE yylloc.first_line = yylloc.last_line = oslcompiler-

lineno()
And here is the lex code:

#define yylloc osllloc

void preprocess (const char *yytext);

// Macro that sets the yylloc line variables to the current parse
line.
#define SETLINE yylloc.first_line = yylloc.last_line = oslcompiler-

lineno()
%}

%%
