Tk-segfaults当我使用小部件（按钮，文本） [英] Tk - segfaults when I use widget (button, text)
问题描述
> wm标题。 mysh
> wm几何。 300x300
但是当我尝试按钮或任何其他小部件时，它会删除
>按钮.b
分段错误
我在gdb中加载了这个，并运行了一个back trace
程序接收信号SIGSEGV，分段故障。

您在 comp.lang.tcl ，而解决方法是在配置时指定 - disable-xft Tk。
我怀疑真正的原因是无法链接XML解析器，由于系统的原因，这在一些最新版本的Linux上被报告为潜在的问题更改为传递依赖关系的处理方式。 （我忘记了哪个供应商负责;我最近没有对开发人员的讨论付出很多的关注）。你能报告什么是 ldd Tk的报告图书馆（没有解决方法）以及你正在建立的确切操作系统？此外，您正在尝试建立哪个版本的Tk？还要注意，在跟踪问题时，使用T $和Tk的 - enable-symbols 配置选项将更为有用，因为这样可以让您在堆栈中获得更好的信息痕迹。
I have compiled Tcl/Tk into my application. When I open my application, I get a window (due to Tk_init) which I can manipulate:
> wm title . "mysh"
> wm geometry . 300x300
But when I try button or any of the other widgets it segfaults
> button .b
Segmentation fault
I loaded this in gdb and ran a back trace
Program received signal SIGSEGV, Segmentation fault.

I think there is some problem with Fonts. Any idea to fix this?

You asked this question on comp.lang.tcl, and the workaround is to specify --disable-xft when configuring Tk.
I suspect that the real cause is a failure to link an XML parser, which was reported as being a potential issue on some recent versions of Linux due to a system change to the way that transitive dependencies are processed. (I forget which vendor is responsible; I wasn't paying that much attention to the developer discussion where this was thrashed out recently.) Can you report what ldd reports for the Tk library (without the workaround) and what exact OS you're building on? Also, exactly which version of Tk are you trying to build against? Also note that it is enormously more helpful to use the --enable-symbols configure option to Tcl and Tk when tracing down a problem, as that lets you get better information in stack traces.
