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.

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.

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.
