Hey Fadi, do you think you can thread this email thread a little better? Right 
now (for whatever reason) a bunch of your emails are getting new threads in 
mail. It would be a lot easier to track/respond to the email if you always 
responded in the same mail thread.

[Just friendly advice = )]

Interesting...

You might want to add these discoveries to the SR that I mentioned, or file a 
new one with these comments.  At this point you're trying to help out the folks 
working on SPM and a bug report is a more direct way to do that than the 
swift-users list.

It seems the modules are compiled and linked SEPARATELY in Xcode, and this 
succeed in debuggingBut in SPM, all are compiled as one module (it may have 
submodules)
I think if you provide something compiles to dynamic link libraries on Linux 
(and SPM in general) like frameworks on macOS, it will solve the problem

It does look like this is a known bug (not yet fixed) in SPM:
https://bugs.swift.org/browse/SR-3280
The bug isn’t fixed yet (apparently it’s blocked on a swift compiler issue.)  
There’s a workaround in that report, though I don’t know how viable it is.  
Anyway, you can track that bug to see when this gets fixed.

 الموضوع: Re: بخصوص: بخصوص: [swift-users] About Swift Package Manager and LLDB
  
It isn’t quite as mysterious as that.  lldb emulates the context of the frame 
you are stopped in when you run “frame variable” or “expression”.  It looks 
like PerfectTemplate doesn’t have a problem, and doesn’t rely on modules that 
we can’t reconstruct.  But some of the other modules do have problems.  For 
instance, if I let the program come up, interrupt it and switch to a frame in 
the PerfectHTTPServer, then I see:
(lldb) expr let $mystr = "Some string"error: in auto-import:failed to get 
module 'PerfectHTTPServer' from AST context:error: missing required modules: 
'PerfectCHTTPParser', 'PerfectCZlib'

But that’s not the only one with problems, and I’m still not getting any useful 
error messages back from swift.  I’ll have to dig into this more.

Swift doesn’t seem to be reporting whatever the error is, I just see:

That’s not very helpful.  Again, I’ll probably need to make this happen locally

 الموضوع: Re: [swift-users] About Swift Package Manager and LLDB
  
The log for “print self” was unfortunately captured too late.  Reading in the 
PerfectTemplate module had already failed, and so any subsequent attempt will 
just report it as failed.  To get the complete error log for this, you need to 
put:
log enable -f /tmp/lldb-type-log.txt lldb types
in your ~/.lldbinit file and then start a fresh debugging session and capture 
the whole session.
The failure from the REPL  is because you have to tell the REPL where to look 
for other frameworks from which it might load modules.  You can pass 
appropriate -I, -L and -F flags to the “swift” invocation too tell the compiler 
lldb’s using to implement the REPL where to look for this module.
The example you gave seems to be a MacOS X example.  The binary type was MachO 
etc.  If this is just a small example that you are using to demonstrate the 
problem, can you file a PR with the swift bug reporter with this example and 
how you built/ran it and we can take a look here.  That’s probably easier than 
trying to pass logs back and forth.

OK You want it locally
It is just the PerfectTemplate without ANY CHANGE (Perfect framework by 
PerfectlySoft)
(Also Kitura makes the same problem, but I didn't try to get a full log to see 
whether the same problem or not)

Swift doesn’t seem to be reporting whatever the error is, I just see:
((SwiftASTContext*)0x7f8c555c84a0)->GetModule('PerfectTemplate') -- failed with 
no error

That’s not very helpful.  Again, I’ll probably need to make this happen locally 
to see what went wrong.  If you have a project that shows the issue which you 
can make available, please file a bug with a description of how you build and 
debug this app, I’ll take a look.

The log for “print self” was unfortunately captured too late.  Reading in the 
PerfectTemplate module had already failed, and so any subsequent attempt will 
just report it as failed.  To get the complete error log for this, you need to 
put:
log enable -f /tmp/lldb-type-log.txt lldb types
in your ~/.lldbinit file and then start a fresh debugging session and capture 
the whole session.
The failure from the REPL  is because you have to tell the REPL where to look 
for other frameworks from which it might load modules.  You can pass 
appropriate -I, -L and -F flags to the “swift” invocation too tell the compiler 
lldb’s using to implement the REPL where to look for this module.
The example you gave seems to be a MacOS X example.  The binary type was MachO 
etc.  If this is just a small example that you are using to demonstrate the 
problem, can you file a PR with the swift bug reporter with this example and 
how you built/ran it and we can take a look here.  That’s probably easier than 
trying to pass logs back and forth.

Also there is some very weird thing happens
When I use ^C to stop debuggingthen REPLimport PerfectTemplate
There is no error
But when use breakpointThe error happens
Is there something weird about breakpoints ?
Also please note that on macOS when I use SPM to convert project to Xcode 
project and compile using xcode-build all work perfectly(This is inconvienient 
since servers are Linux, web debugging must be on Linux)

I'm using macOS Sierra (sorry didn't have time to upgrade), with Swift 4 that

The only succeeded way is to generate an xcodeproj and compile it, this is
