Linux GDB的错误

GDB的时候，出现了错误：

Tcl_Init failed: Can't find a usable init.tcl in the following directories:
    /usr/local/share/tcl8.0 /usr/share/tcl8.0 /usr/local/share/tcl8.0

 

This probably means that Tcl wasn't installed properly.

查了一下，是TCL/TK的错误，它是图形交互界面设计的一种工具。但是GDB和它有什么关系呢？

想了一下，出现错误的虚拟机都是编译过内核和交叉工具的，是不是这个过程覆盖了什么呢？GDB应该是交叉工具的一个部分，所以可能被覆盖了。

一般的命令都是在/usr/local/bin下，在那个目录下：#gdb -v，得到
GNU gdb 5.0

事实上，这应该是不适合的版本。在/usr/bin下的gdb是：
GNU gdb Red Hat Linux 7.x (5.0rh-15) (MI_OUT)

这是Redhat Linux上适合的GDB。这样应该是编译交叉工具的时候，用上面版本的GDB覆盖了原来/usr/local/bin下的GDB，做一下软连接就可以了。

 

不过，注意到arm-elf-linux-gdb也是同样的提示init.tcl错误，暂时不解决这个问题。
