我已将 Tcl/Tk 编译到我的应用程序中。当我打开我的应用程序时,我得到一个可以操作的窗口(由于 Tk_init):

> wm title . "mysh"
> wm geometry . 300x300

但是当我尝试按钮或任何其他小部件时,它会出现段错误

> button .b
Segmentation fault

我在 gdb 中加载了它并运行了回溯

Program received signal SIGSEGV, Segmentation fault.

我认为字体有问题。有什么想法可以解决这个问题吗?

您在comp.lang.tcl上提出了这个问题,解决方法--disable-xft是在配置 Tk 时指定。

我怀疑真正的原因是链接 XML 解析器失败,据报道,由于系统更改了传递依赖项的处理方式,这在某些最新版本的 Linux 上是一个潜在问题。(我忘记了哪个供应商负责;我没有太关注开发人员最近讨论的问题。)您能否报告lddTk 库的哪些报告(没有解决方法)以及您正在构建的确切操作系统在?另外,您到底要针对哪个版本的 Tk 构建?--enable-symbols另请注意,在跟踪问题时使用 Tcl 和 Tk 的配置选项会非常有帮助,因为这可以让您在堆栈跟踪中获得更好的信息。
