Run a command in the background in Ubuntu

Use (setsid yourcommand &), it detaches from the tty and works equally in interactive and script modes.

CoolOppo / launch4j error fix for Java 8 on Windows.md
Last active August 29, 2015 14:05

launch4j exec error

I was having a shit ton of problems getting launch4j to work. Simply get a recent version of MinGW's ld.exe and windres.exe files, and replace the ones in the bin folder. That seems to do the trick.

Another thing to try is using the DOS path instead of the standard Windows one when you refer to the directory containing JRE. Apparently, the tool doesn't support paths with spaces in them, although it is somewhat sporadic. I used cygpath to generate my path. The command I used is cygpath -wsa "C:\Program Files (x86)\Java\jre1.8.0_20", which resulted in C:\PROGRA~2\Java\JRE18~1.0_2 as the DOS path.

A working XML config for launch4j is below.

<?xml version="1.0" encoding="UTF-8" ?>
