Ok, I got the key. The module library should be located at auto/FooBar/FooBar.so instead of auto/FooBar.so...

============================================

Hi monks!

I'm writing a module with XS, which is a wrapper for another library. I made a simple test on my module:

1. link FooBar.pm to current directory,

2. link compiled FooBar.so to ./auto/,

3. then run perl -MFooBar, and it cries:

Can't find 'boot_FooBar' symbol in /usr/local/lib/libFooBar.so
 at - line 0.

This is strange, as boot_FooBar is compiled in the perl wrapper library, so it should not be searched in the original library.

I'm sure boot_FooBar is inside auto/FooBar.so, by using readelf -s:

46: 00000000000048a4  1049 FUNC    GLOBAL DEFAULT   11 boot_FooBar

In addition, I did not use any perl helper modules (like Module::Build or ExtUtils::MakeMaker) to build my module. I did everything manually.

In reply to XS module cannot find boot_FooBar symbol by llancet
