getting started

[ddyer0]

I'm no novice, but I've been unable to get the samples to compile or find any active support forum.

On Windows 7, the complaint is
LLVM ERROR: Error: Unable to launch the Java Virtual Machine.
I have about a dozen JVMs installed, the default is 64 bit java 1.8_05

It would help if there were some FAQ about specifying explicitly what JVM to use.
Or a more visible community forum. The adobe forum is essentially unused.

Try setting JAVA_OPTS environment variable (-Xms1024m -Xmx8192 in my example):

Setting JAVA_OPTS environment variable made no difference, but I eventually succeeded by adding
-jvmopt=-Xmx1G to BASE_CFLAGS in Makefile.common

The next stumble is while compiling sample 5
-------- Sample 5 --------

Now compile a SWC and demo SWF

Looks like a path issue:
Try using: $(call nativepath,$(FLEX))
Or directly: $(shell cygpath -at mixed $(FLEX))
Also space in path names could lead to errors, you can move the sdk or use shortened path:
/cygdrive/c/Progra~1/Flex...
Also you can use AIR SDK instead of Flex:

It was a path issue, moving the target sdk to /cygdrive/c/crossbridge/4.6.0 worked

Where does the default value (that I had to override) -Xmx1500M come from? It doesn't appear anywhere in distribution that I can find.

line 158

I've removed this in my fork because I think it's better to depend on JAVA_OPTS env. or supply by param.

After the above, the "samples" build still failed on sample 5.

My explanation is that my typical devlopers path is full of all kinds of stuff, including perl,
msvc, some version or other of cygwin, some random unix command tools, and so on.
I eventually fixed the rest of the samples build process by cleaning up my path.

In run.bat, before the path modification

set a minimal path to avoid contamination of the environment with unexpected programs

note this includes the JDK path we want to use

set path=C:\java\jdk1.8.0\bin;C:\windows\system32;C:\windows;C:\windows\System32\Wbem;
