我在下载编译最新版本的nanhu分支时失败，具体错误日志见附件；
内存大小已经配置成80G还是同样的错误；

What did you do before

只是下载了最新的代码进行编译

感谢报告这个问题，但目前我无法复现，我在 nanhu 分支 commit 2a5ed12 上使用 make emu编译，一切正常。有一些问题：

1. 您是否在编译前执行过 make init？
2. 您使用了什么命令进行编译，是 make emu 吗？
3. 您是否尝试过删除编译临时文件（即，rm -rf build out）

内存大小已经配置成80G还是同样的错误；

从错误日志来看应该不是内存问题。

Thanks for reporting this, but I was not able to reproduce the issue. So:

1. Have you run make init before compiling?
2. What command are you using to compile (e.g. make emu)?
3. Have you tried removing temp files (i.e. rm -rf build out)?

1、make init运行过
2、我是用make verilog 编译的
3、有试过make clean后重新编译

[ngc7331]

好，看起来是 make verilog 存在一些问题，我们会进一步定位，感谢反馈！

Now I reproduce the issue, seems make verilog does broken, we'll further investigate, thanks for the feedback!

看起来这是 difftest 的 Gateway 的修改导致的（ OpenXiangShan/difftest@43a308e#diff-c7e5360794f36dddaf7369c40275c16170784c4b981ab55a3f843f8af69526acL65-R165 ），在 42f9ef1 更新到 nanhu 分支

您可以尝试：

• 使用一个更早的 commit（如，git checkout 42f9ef138dd453235be00d6a45f2a8d7c109c364^），或者，
• 使用我的修复分支（即，git checkout nanhu-fix-make-verilog），不过我不是完全确定这么修是不是对的，所以这个方案还需要等负责的同学确认一下。

请 checkout 后重新运行 make init && make clean && make verilog，看看能否正常编译。

Seems this is caused by OpenXiangShan/difftest@43a308e#diff-c7e5360794f36dddaf7369c40275c16170784c4b981ab55a3f843f8af69526acL65-R165 and was introduced to nanhu in 42f9ef1

You can try:

• a former commit (e.g. git checkout 42f9ef138dd453235be00d6a45f2a8d7c109c364^), or,
• the fix branch (i.e. git checkout nanhu-fix-make-verilog), though I'm not an expert on difftest so this is waiting for out team member to review.

Then re-run make init && make clean && make verilog to see if it can compile.

我发现昆明湖主干make verilog也有问题，你们也可以查下。

我发现昆明湖主干make verilog也有问题，你们也可以查下。

我在 kunminghu-v3 和 master 上都可以正常编译，检查代码后感觉也不是同一个问题，您能否提供编译日志？

I can compile normally on both kunminghu-v3 and master, and I don't think it's the same problem after examining the code, can you provide build log?
