I managed to create a “.app” bundle of my application, and then I linked the libraries ecl and eql following this approach (https://stackoverflow.com/questions/2809930/macdeployqt-and-third-party-libraries <https://stackoverflow.com/questions/2809930/macdeployqt-and-third-party-libraries>):

It looks like the error, which is:


Internal or unrecoverable error in:
Got signal before environment was installed on our thread
  [2: No such file or directory]

is unrelated to the libraries. 

To be sure, have a look at the source of cl_boot (around assembly offset 1025) to see what it’s doing there.
(You may use lldb to disassemble cl_boot and see what function is called around offset 1025, to help you locate the source of the error).



(Concerning the warnings, did you copy the frameworks to the application package?)
