Question

首先，我对此很新。我正在尝试编译T1架构和模拟建模工具（http://www.oracle.com/technetwork/systems/opensparc/opensparc-t1-page-1444609.html），使用Sun Studio 12.3作为Solaris 10上的编译器和Sparc处理器。

我正在运行脚本“build_sas.sh”并遇到编译错误。

我不确定源代码中的错误是什么。这是源代码：

#include "StdMacros.h"

    dataHandler_(data)

我非常感谢您的帮助/建议。

Answer 1

尝试使用编译器选项-features=rvalueref。软件附带没有构建说明吗？

Answer 2

您强制使用-xarch=sparcvis的SPARC VIS扩展指令，这些指令未包含在T1中。 VIS和VIS +是UltraSPARC III + IV +特定的。运行isainfo -bv以查看CPU支持的内容。如果不进行交叉编译，请使用-xarch=native。
