Addressing some of the comments:

- The long list of errors was caused by one of the first errors as syphilis said. Makefile.PL was outputting '#define XP_PC' to Javascript_Env.h, and the first error said that I needed to define "XP_BEOS, XP_OS2, XP_WIN, or XP_UNIX". So I changed 'XP_PC' in Makefile.pl to 'XP_WIN' and now I only get this.

- I built SpiderMonkey 1.7 following the instructions here. I first downloaded the Mozilla Build environment and Visual C++ 9. Then I used the start-msvc9.bat in the mozilla-build folder (I think this is minGW) and followed the instructions on the web page to build the optimized/non-debug Spidermonkey. I think it worked as there is a shell (js.exe) in the ../jd/src folder that can read print("Hello world").

I stopped using minGW because when I tried to run Makefile.pl I was prompted that I needed perl version 5.8 and minGW only had 5.6.1 or something. So I'm now just using the windows command prompt.

- Finally, I tried the Javascript.pm from the repository and it seems to work great. I needed it for another module that was dependant on Javascript.pm. I guess that is problem solved, but I'd still be curious about getting it right the hard way.

Thanks for the help.

Please send me a patch with what you needed to change in order to get it to work on Windows and I'll integrate it.

preferably against the git repo http://github.com/claesjac/javascript.git

To be honest I have no idea how to make patch. :( I'm pretty much a noob at perl and programming in general.

I really don't think I changed much though. I was still running into problems with the makefile.pl. Then I just decided to use the PPM shell and typed install JavaScript and that worked. I can now use the module in perl. I don't think anything I did before was a contributing factor to whether or not the Javascript.pm from the repository worked..

Either way, the only changes I made anywhere was in Makefile.PL. The first thing I did was set the JS_INC and JS_LIB keys in the ENV hash to the correct directories. I did this by just assigning them a string value of the correct directories, so ...

$ENV{JS_INC} =  "C:\\strawberry\\js\\src";
$ENV{JS_LIB} =  "C:\\strawberry\\js\\src\\WINNT5.1_OPT.OBJ";

This "fix" is obviously very specific to my situation, so I don't know if it could help others that use different directories.

Also in this section of the code, I changed $lib="js" to $lib="js32", because my .lib file was called js32.lib.

if (exists $ENV{JS_LIB}) {
    @libs = get_paths($ENV{JS_LIB});
    $ENV{DYLD_LIBRARY_PATH} = $ENV{LD_LIBRARY_PATH} = $ENV{JS_LIB};
    $lib = "js";
}

After that, the makefile.pl would give the correct gcc command with the correct directories, but now it would return a ton of compiling errors. and the first error was something like this:

C:\strawberry\cpan\build\JavaScript-1.12-mJTECJ>makefile.pl
In file included from C:/strawberry/js/src/jspubtd.h:45,
                 from C:/strawberry/js/src/jsapi.h:47,
                 from JavaScript_Env.h:10,
                 from test_js.c:2:
C:/strawberry/js/src/jstypes.h:248:6: #error "Must define one of XP_BE

+t16/JSUint16
C:/strawberry/js/src/jstypes.h:297:2: #error No suitable type for JSIn
+t32/JSUint32
[download]

It was asking for XP_BEOS, XP_OS2, XP_WIN or XP_UNIX, and I saw that JavaScript_Env.h had a line that said

#define XP_PC

So I edited the Makefile.pl again so that it would now ouput 'XP_WIN' in place of 'XP_PC' to the .h file. This would no longer generate a super long list of compiling errors. Instead it started returning this:

C:\strawberry\cpan\build\JavaScript-1.12-mJTECJ>makefile.pl
C:\DOCUME~1\Steve\LOCALS~1\Temp/ccQm7OVj.o:test_js.c:(.text+0x2b): und
+efined ref
erence to `JS_GetImplementationVersion'

Those are the only changes I made. If I try to run makefile.pl now, I still get that message. I don't know what causes it or how to fix it. I'm doing this all in the cpan/build folder where cpan downloads the Makefile and other module components.

All these undefined reference to _imp_, are present in the *.o files, and error is because of order of *.o files. I can't figure out the correct order.

I stopped using minGW because when I tried to run Makefile.pl I was prompted that I needed perl version 5.8 and minGW only had 5.6.1 or something. So I'm now just using the windows command prompt.

I can't make much out of that. It sounds like perl-5.6.1 was found, but perl-5.8.x is needed - however, that would have nothing to do with MinGW (or any other compiler).

When you ran 'perl Makefile.PL' which version of perl was being run (running 'perl -v' will tell you) ? Do you have more than one perl installed on your machine ?

Also, the actual output of 'perl Makefile.PL' might help us determine the problem and solution.

It sounds like he is trying to build JavaScript from within MSYS (which he used to compile SpiderMonkey). MSYS comes with perl 5.6.1.

The MinGW was in the "Mozilla Build 1.14" package that I needed to build Spidermonkey. The package also included Perl v 5.6.1, so when I tried to run Makefile.pl in MinGW, it would say that I needed v5.8. I figured this wasn't a big deal though b/c I wanted to install Javascript.pm into the strawberry folder anyway. I guess that little note was irrelevant.

perl -v in MinGW returns 5.6.1
perl -v in the windows command line says 5.10.0

Looking at makefile.pl, it creates a JavaScript_Env.h file. It also creates a test_js.c file which is supposed to do a small compile to see if libs and headers can be located. It then outputs a gcc command to the command line. I think the gcc command is causing a problem. Here is what the gcc command I'm sending looks like:

gcc -LC:\strawberry\js\src\WINNT5.1_OPT.OBJ -ljs32 -o C:\DOCUME~1\Stev
+e\LOCALS~1\Temp\b4to8dFiQI -IC:\strawberry\js\src test_js.c

dunno if that helps.
