Its not defining the functions Ian. The issue is both the packages A and B
are linking the same library
package A:
/*
#cgo LDFLAGS: -Bstatic ${SRCDIR}/../lib/libeventbridge.a
*/
The same thing in package B:
/*
#cgo LDFLAGS: -Bstatic ${SRCDIR}/../lib/libeventbridge.a
*/
Please note:
1. Without including the library in these packages, the linker of the
individual package fails indicating that the definition of the functions
used is not found.
2. Package B imports package A
Thanks,
Sriram
