Greetings, I'm trying to compile the java FOP (formatting objects processor) to run natively on windows. One may ask: WHY? The reason is that we have some computers on which we are not allowed to install a JRE but we would anyway love to use FOP for rendering docbook documents to PDF. Unfortunately I ran into some trouble compiling it, which is why I'm searching for help on this list. This is where it fails: --- QUOTE --- org/apache/fop/accessibility/AccessibilityPreprocessor.java: In class 'org.apache.fop.accessibility.AccessibilityPreprocessor': org/apache/fop/accessibility/AccessibilityPreprocessor.java: In constructor '(javax.xml.transform.sax.TransformerHandler,javax.xml.transform.Transformer ,org.apache.fop.apps.FOUserAgent,org.xml.sax.helpers.DefaultHandler)': In file included from org/apache/fop/accessibility/AccessibilityEventProducer.java:0:0, from org/apache/fop/accessibility/AccessibilityEventProducer.java:42, from org/apache/fop/accessibility/AccessibilityEventProducer.java:43, from org/apache/fop/accessibility/Accessibility.java:44, from org/apache/fop/Version.java:37, from org/apache/fop/ResourceEventProducer.java:1, from org/apache/fop/ResourceEventProducer.java:52, from org/apache/fop/ResourceEventProducer.java:58, from <built-in>:3: org/apache/fop/accessibility/AccessibilityPreprocessor.java:50:0: error: cannot find file for class org.apache.commons.io.output.ByteArrayOutputStream org/apache/fop/accessibility/AccessibilityPreprocessor.java:50: confused by earlier errors, bailing out make: *** [fop.exe] Error 1 --- QUOTE --- What I've done so far is: * use maven to fetch all required dependencies * use cygwin for: * make (3.81) * gcj-4 (4.5.0) * use make as frontend to gcj I pasted the Makefile here: http://pastebin.com/yEJGzEbA And the pom.xml here: http://pastebin.com/LRbJMVMd What I do not get is, that there's definitely the .class file for ByteArrayOutputStream in commons-io-1.3.1.jar. Can someone explain me what I am doing wrong here? Thanks in advance, D.
