Re: 答复: Inquiry whether jdk8u can compile with icc？

[Erik Joelsson]

Hello VicWang,

The native source for Linux is written for GCC. Making it work with a 
different compiler is likely a lot of work that requires deep knowledge 
both in the JVM source and with the particular compiler. I have neither. 
Even if you got it to compile it's unlikely to work well since nobody 
(that I know of) has tested the combination before.

I recommend that you build with the supported compiler instead. What do 
you expect to gain from using ICC?
