[blfs-support] Webkit 2.20.1 error

[spiky]

Building Webkit 2,20,1 I get an error fails to find
"/webkitgtk-2.20.1/Source/JavaScriptCore/JSContextRef.h"

This file is in "/webkitgtk-2.20.1/Source/JavaScriptCore/API/JSContextRef.h"


it is read from the file
/webkitgtk-2.20.1/Source/JavaScriptCore/API/JSHeapFinalizerPrivate.h

(#ifndef JSHeapFinalizerPrivate_h
#define JSHeapFinalizerPrivate_h

#include <JavaScriptCore/JSContextRef.h>
#include <stdbool.h>)

How can I get round this error. Also is it going to be able to find
other files?

We need a little more info Spiky. What was the build instruction that
failed? It sounds like a missing -I parameter. As a workaround you
could try LIBRARY_PATH=/webkitgtk-2.20.1/Source/JavaScriptCore/

I did check and I do have that file, but I had no problem building with
the book's current instructions.

If I have made a mistake I dont know where. This was a copy paste of the
book commands

Hmm. I don't get the LLIntDesiredOffsets.h line until 43% and the
LLIntOffsetsExtractor.cpp.o build several lines later. I used -j4.
What parallelism did you use? You could try -j1, although it will take
a long time.
