Additional context

不知道是哪里的问题？

java 11/17都尝试过；物理内存512G

应该不是OS的问题，因为南湖版本编译单核、双核、四核都未出现此情况

[TRANSLATION]

I'm not sure what the issue is?

I have tried Java 11 and 17; the physical memory is 512G.

It should not be an OS issue, because the Nanhu version has compiled single-core, dual-core, and quad-core without encountering this situation.

Have you tried make verilog NUM_CORES=1 in your environment?

[cebarobot]

考虑到您在使用的是 CentOS 7.9，感觉还是环境配置的有些问题。如果可能，我们还是推荐使用 Ubuntu 22.04。

Considering you are using CentOS 7.9, it is probably a environment problem. If possible, we recommand you to use Ubuntu 22.04.

能否请您提供下面这些命令的运行结果，来辅助我们判断环境问题：
Could you please provide output of the below commands:

mill -i --version
java --version
echo $JAVA_HOME

尝试了，生成单核rtl是可以正常生成的，没有错误

[TRANSLATION]

I tried, and the single-core RTL can be generated normally without any errors.

It's really strange... Have you tried to make clean or re-clone the XiangShan project?

这就很怪了。您尝试过 make clean 或者重新 clone 香山项目吗？

尝试过make clean && rm -rf out ，也尝试过重新 clone代码。我刚才尝试，将jvm参数改成-Xmx200G -Xms200G 没有加-Xss参数，make verilog NUM_CORES=4也能正常编译，但是make emu或者simv会出现上述错误

I have tried make clean && rm -rf out, and also tried to re-clone the code. I just attempted to change the JVM parameters to -Xmx200G -Xms200G without adding the -Xss parameter. make verilog NUM_CORES=4 can compile normally, but make emu or simv results in the aforementioned error.

make emu/simv 会出现java ClassNotFoundException, 但是检查发现对应的object都存在，更改Xmx参数大小还会导致报错的objec不一样，不知道哪里出现的问题

[TRANSLATION]

Running make emu or simv results in a Java ClassNotFoundException, but upon checking, the corresponding objects are found to exist. Changing the size of the Xmx parameter can also cause different objects to be reported as errors, and I am unsure where the problem lies.
