WEE-41 UPX fail on Ubuntu 15.10 64-bit

This is very strange. On WEE-41 and several previous versions I have experienced strange results with the Translate-Compile option.

The upx code seems to be executing prior to the translate compile code.

This is a capture of the lxterminal cosole output upon running wee.exw v. 41 in a terminal and then selecting translate and compile with only the test run after bind/shroud translate option selected:

kenneth@kenneth-desktop:~/wee/wee41$ eui wee.exw wee.exw 
/usr/bin/upx 
                       Ultimate Packer for eXecutables 
                          Copyright (C) 1996 - 2013 
UPX 3.91        Markus Oberhumer, Laszlo Molnar & John Reiser   Sep 30th 2013 
 
        File size         Ratio      Format      Name 
   --------------------   ------   -----------   ----------- 
upx: wee: FileNotFoundException: wee 
 
Packed 0 files. 
 

The "Run in background" option was not selected. A gnome-terminal window opened immediately and reported the progress of translation/compile operation during which time the wee.exw code page remained unshaded. Upon completion of the translation/compile process the gnome-terminal window closed. A check of the wee41 folder revealed that the file had been translated/compiled, but not packed by UPX:

kenneth@kenneth-desktop:~/wee/wee41$ ls -s 
total 2996 
   4 EuGTK        4 scintilla      48 ui_gtk.e   *** 2676 wee ***        12 weeicon.e 
  84 parser.e    76 scintilla.e     4 updater.ex    88 wee.exw 
 
{{{ 
 
When I run the translate/compile option again. The upx function executes immediately and compresses the wee binary created by the previous run. 
 
{{{

Packed 1 file. 
 

Then the wee.exw code is translated and compiled again, overwriting the previously created compressed wee binary.

On the second run the editor window shaded and remained shaded and unresponsive, even after the translation/compile task completed. I had to force the unresponsive window to close.

Bind fails in the same manner. On the first run, upx will try to compress filebase(file_name) before executing eubind, then a bound version of file_name is created which is not compressed. On the 2nd run, the previously created bound file is compressed; however execution fails with the message:

kenneth@kenneth-desktop:~/wee/wee41$ ./wee 
<0302>:: no Euphoria IL code to execute 

I do not believe that bound euphoria programs are compressable with upx.

I edited the translate compile clause in RunStart as follows:

-- insert before RunStart in ui_gtk.e 
function background(sequence cmd) 
-- for use with system_exec(cmd[1], cmd[2]) 
    cmd &= " &" 
    cmd[1] = cmd 
    cmd[2] = 1 -- the previous graphics mode is restored  
               -- and the screen is cleared.  
    if run_background then 
        cmd[2] = 0 -- a beep sound will be made and the program will wait for the user to press a key before the previous graphics mode is restored.  
    end if 
return cmd 
end function 
 
-- replaces existing translate/compile code in function RunStart. 
-- if run menu option "Run in Backround is not selected 
-- progress will be reported in the 
-- system default terminal emulator 
-- a keypress is required to proceed 
-- to the next process. 
 elsif equal(lbl, "Translate and Compile") then 
	if file_exists(filebase(file_name)) then 
-- else upx will execute first, 
-- compressing the existing file, 
-- and then a new file will be created, 
-- which will not be compressed!	    delete_file(filebase(file_name)) 
	end if 
        cmd &= get_eu_bin("euc") & ' ' & quote_spaces(file_name) 
        cmd = background(cmd)  -- requires function background(sequence cmd) 
	if system_exec(cmd[1], cmd[2]) = 0 then  -- file translated/compiled successfully 
            cmd = "upx " & filebase(file_name)  
            cmd = background(cmd) 
	    if system_exec(cmd[1], cmd[2]) = 0 then  -- executable file packed successfully 
                if run_testrun then 
                    cmd = "./" & filebase(file_name) 
                    cmd = background(cmd) 
                    if system_exec(cmd[1], cmd[2]) = 0 then 
                    end if 
                end if 
            end if 
        end if 

Perhaps it would be easier not to support upx. Or maybe add a discrete option to the Run menu.
