| Subject: | unresolved external symbol boot_version__vxs |
Commit https://bitbucket.org/jpeacock/version/commits/c2cc74f7ebf49c57504f914ede77c3d873e6d70c "Do not need vxs.xs any longer" looked suspicious to me. I tried to compile the head commit https://bitbucket.org/jpeacock/version/commits/8f1352c79510f2f9c9fc58e048dfc57286d28626/raw/ "Only need to compare the remaining string" and got this.

boot_version__vxs AKA BOOT: is the only sub Dynaloader creates from a SO/DLL, so the rest of the XSUBs are registered from boot with newXS calls. This is how xsubpp and nearly all (but not all, see this tutorial module https://github.com/tsee/p5-XS-WithoutXS/blob/master/lib/XS/WithoutXS.pm ) other xs libs do it.
