<div dir="ltr">raco exe works by traversing the requires of the modules it is embedding, putting all of that bytecode (usually bytecode, but not always) into the application and then setting up low-level hooks when the exe is run so that requires of the embedded modules are redirected to the bytecode that is embedded. <div> </div><div style>This process can be defeated by using dynamic-require, say, or generally by requiring a module that a traversal of the require hierarchy cannot "see".</div><div style> </div><div style>hth,</div> <div style>Robby</div></div><div class="gmail_extra"> <div class="gmail_quote">On Tue, Jan 29, 2013 at 10:31 AM, Galler <<a href="mailto:lzgaller@optonline.net" target="_blank">lzgaller@optonline.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Some additional detail: 1) the flomap exception below shows up when attempting to run compiled code in both releases 5.3 and 5.3.1 2) the application works in both releases of DrRacket, behavior only occurs when compiled via raco exe behavior which makes me think (as Robby pointed out) the same libraries aren't being shared between DrRacket and raco exe (is this possible???) 3) I'm still working on isolating and localizing the fault, including compiling and running parts of the application separately. The issue is (with high prob.) is in a module using #lang web server sitting at the top of my hierarchical stack of modules. To verify this, I've compiled the non-#lang web server modules under raco exe (5.3.1) and exercised them without difficulty. I'll keep going on this, but as a troubleshooter, it seems like item #2 and that the issue is with flomap and #lang web server above might be dispositive towards identifying the problem<div class="HOEnZb"><div class="h5"> On Tue, Jan 29, 2013 at 7:44 AM, Jay McCarthy wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> [Adding Neil] Do you know what commit fixed the missing require for-syntax in flomap?
