您将能够捕获运行自定义构建步骤时产生的控制台输出吗?看起来nasm工具在此过程中某处返回了错误代码，但实际的错误消息显示在控制台输出中，而不是在构建日志中.

Will you be able to capture the console output produced while running the custom build step? It looks like the nasm tool returns an error code somewhere along the way, but the actual error message is being displayed in the console output and not in the build log.
