答复: Inquiry whether jdk8u can compile with icc？

[Vic Wang(BJ-RD)]

Hi Yumin:

       I’ve solved the compiling bugs by using ICC .
       You’re right. It’s not compatible with the static lib (libirc.a).
       With modifying the LDFLAGS with –lirc, it can make successfully.
       But why using the –O1 when linking? I’ve not clear for all the makefiles. I’ll study more about it.

Best Regards!
VicWang

The first error is known issue and fixed in jdk 9:
https://bugs.openjdk.java.net/browse/JDK-8016451

For the second one, I am not familiar with icc/icpc, it looks the linker find a static version which is not an expected version. you need to check the detail of library dependency.

Hi Erik,

Yeah, it need to modify some configure files before generating the Makefile file. But I am not lucky to build the binary successfully. It occurs some ld's error.

Do you have any ideas for this?
I want to build JVM on intel i5-6600k platform.
Thanks very much.

Hello,

There is no support for ICC as far as I know. If ICC is compatible with the default toolchain for the platform, you may get something to work, but I doubt you will have any luck without modifying build logic.

Which platform are you trying to build on?
