Build fail: unresolved external symbol mainCRTStartup

Thu Nov 14 06:39:13 PST 2013

As Kevin reasonable noted, the problem was that 32-bit and 64-bit parts 
were mixed up. I checked the build scripts and found that there were two 
ways of getting the platform architecture there:

1. ext.OS_ARCH = System.getProperty("os.arch") in build.gradle
2. procarch = $$(PROCESSOR_ARCHITECTURE) $$(PROCESSOR_ARCHITEW6432) in 
rt\modules\web\src\main\native\Source\JavaScriptCore\TargetJava.pri

At my PC, the former (via system property) returns "x86", while the 
latter (via environment variables) results to "X86 AMD64". I guess this 
makes a small part of the web module to be built in 64-bit mode, while 
the rest is 32-bit, causing to the linkage error.

So, to build successfully, one can either install 64-bit JDK, or change 
the build script for the two variables to match. I tried the both 
approaches, the both worked.
