I have a problem with a native library dependency in my project SwiftTerm, the native library dependency
is a wrapper for libssh, and I compile this as a .framework which I then reference from SwiftTerm.
The problem is that on the same system where I build the .framework, something makes the build system go poking at the original site where the code was built, and produces this error:
/Users/miguel/cvs/SwiftTerm/SwiftSH.binaries/module.modulemap:1:8: error: redefinition of module 'Libssh2'
module Libssh2 {
^
/Users/miguel/cvs/SwiftSH/libssh2/module.modulemap:1:8: note: previously defined here
module Libssh2 {
^
The first one is the binary framework that I am using on my project, the second is not referenced in my project, and is the location where I produced the SwiftSH.binaries.
This path seems to be referenced from the .swiftmodule files
The way I have been dealing with this is that I build my binary framework, and then chmod 0 the directory where I built it, to make it inaccessible, and that gets me over the hump.
I must be doing something wrong.
This is the invocation that fails:
