Perl: undefined symbol: Perl_Gthr_key_ptr

Question:

I try to install the Chilkat Perl library into my Linux but I get this error:

“/usr/lib/perl5/site_perl/5.8.8/libchilkat.so: undefined symbol: Perl_Gthr_key_ptr”

Answer:

The Chilkat library is supports multi-threading, so when building Perl one must use the “Multi-Threading” option.
