View Full Version : No output returned for Sencha Cmd 3.0
21 Nov 2012, 12:51 PM
I installed Extjs 4.1.1a and Sencha Cmd 18.104.22.168 on my Window XP Professional machine. When I type in 'Sencha' in the dos window I should get 'Sencha Cmd v3.0.0', however I get no output. I made sure I ran the command in the Extjs SDK folder (c:\sencha\ext-4.1.1a). My understanding is I do NOT need SDK build tool when using Extjs 4.1.1a and Sencha Cmd. I tried setting it up on my home pc (Windows 7) and the command runs fine. Any help would be appreciate. Thanks!

Update on problem. I installed a newer version of the Java SE runtime (version 1.6 update 37) and the command line works OK. Had an older version of the Java 1.6 runtime.

You can hack the 'sencha' shell script to see the error that's occuring. By default, it seems to output stderr to a file called 'stderr.txt', but then deletes it before the program exits. So if there's an exception, you just get blank output.
MAKE A BACKUP COPY ?of the sencha command first.
Look for this line:
java $jvmArgs -jar $BASEDIR/sencha.jar "$@" 2>stderr.txt
Remove the redirection of stderr to stderr.txt, so the line now reads:
java $jvmArgs -jar $BASEDIR/sencha.jar "$@"
Now, if there is a Java exception, you'll see the stack trace on the console so you have an idea of what's wrong.

Sorry, I just realized you said you're on Windows XP. The steps I mentioned above only work on a Mac or Linux system, or on Windows if you're using cygwin. If you're running on just plain Windows, it runs the sencha.exe file, which of course you can't modify.
