Undefined symbol: PL_no_modify

[yungchunglin]

I cloned the master. It has some glitches so I changed the variable names etc. to make it run.

However I got this error.

Can't load '/usr/lib/perl/5.10/auto/PerlIO/scalar/scalar.so' for module PerlIO::scalar: /usr/lib/perl/5.10/auto/PerlIO/scalar/scalar.so: undefined symbol: PL_no_modify at /usr/lib/perl/5.10/XSLoader.pm line 70.

I think it is caused by override_stdhandle and restore_stdhandle. Somehow, the .so file doesn't load.
As long as I comment out

    this->override_stdhandle(my_perl, outsv, "STDOUT");
    this->override_stdhandle(my_perl, errsv, "STDERR");

and

    this->restore_stdhandle(my_perl, "STDOUT");
    this->restore_stdhandle(my_perl, "STDERR");

The binding can run.

Is there any way to solve this or any workaround?

Thanks.

I couldn't reproduce this issue.
Is there the code that reproduce this?

Hi.

I forked your repo to here https://github.com/yungchunglin/node-perl

Here is my sample js code.

var perl = require('./node_modules/node-perl/build/Release/perl.node').Perl();
perl.Run({
    opts : ["-Mfeature=say","-e","say 'Hello world'"]
}, function(out,err){
    console.log(out);
});

My node.js is 0.6.6

If I specify LD_PRELOAD=/usr/lib/libperl.so.5.10 in the environment, then it runs. Any way to get around this?
