Tk/Tcl 扩展：编译 BLT 时出错

Question

我在OS X 10.10.5下编译BLT，而在./configure后编译make，这里出现了一些错误：

FDSM_lhn@Nirvana:~/Downloads/blt2.4z$ sudo make -I/opt/X11/include

我应该怎么做才能避免这种情况？

您正在使用一个老旧的代码库，因此需要进行一些手术。唉。

需要删除 bltNsUtil.h 中的四个违规声明，因为 Tcl 现在可以正确声明它们； Tcl_FindCommand、Tcl_CreateNamespace、Tcl_FindNamespace 和 Tcl_Export 是 Tcl 的 public API 的一部分，并且已经存在多年。（问题声明位于第 50、67、72 和 75 行，每种情况可能还有一两行。）

此外，建议您在构建本身时不要使用 sudo，而是仅在之后进行安装时使用。仅仅编译代码不需要提升权限。
