Hi,

We have build Perl 5.26.1 from source and used the same Perl to create a perlmodule.c file from an XS file perlmodule.xs. But when we try to execute this C code, we get the following error.
../perlmodule.c: loadable library and perl binaries are mismatched (got handshake key 0xe280080, needed 0xde00080)

Previously we were using Perl 5.16 and there were no issues. Could you please let us know whether we need to rewrite the XS module for Perl 5.26. Currently we are using the same XS module which is used in Perl 5.16. I am not sure if that is creating the issue here.

We are generating the .c files with following command.
perl ExtUtils/xsubpp -typemap typemap -typemap ExtUtils/typemap perlmodule.xs > perlmodule.cpp

Following is the configuration details.
