Re^4: Installing Javascript.pm on XP

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";
[download]

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";
}
[download]

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
+OS, XP_OS2, XP_WIN or XP_UNIX"

C:/strawberry/js/src/jstypes.h:277:2: #error No suitable type for JSIn
+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'
collect2: ld returned 1 exit status
Failed compiling test_js.c. ABORTING
[download]

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.

The 'undefined reference' means that the library that resolves that symbol has not been located. In the Makefile.PL there's a line: `my $cc = join(" ", $Config{cc}, $libs, @ccflags, "-l${lib}", "-o", $ex +e, (map { "-I$_" } @incs), "test_js.c");` [download] It would be helpful if you could insert a `print "$cc\n";` into that Makefile.PL and re-run it again so we can see just what that command ($cc) actually is. I think that `${lib}` in the above command is set to 'js', so 'libjs.a' or 'js.a' or 'js.lib' needs to be found. Is there such a file in in $ENV{JS_LIB} ? Cheers, Rob	[reply] [d/l] [select]
