无法加载文件＆＃34; /usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so"

Question

我在运行magic vlsi时遇到问题。问题是

couldn't load file "/usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so": /usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so: undefined symbol: Tk_GetCursorFromData

我认为这是由：

引起的

 /usr/lib/x86_64-linux-gnu/magic/tcl/magic.tcl
in line 13: load /usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so

该文件 /usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so 存在

运行魔法的错误源来自shellscript display.sh中的qflow：

如何解决此问题？

Answer 1

我应该修改我的答案，因为听起来魔术可能会调用Tcl 8.5而不是8.6，如果您将魔法作为包下载，则可能会发生这种情况。 “加载”的“-lazy”选项仅在Tcl 8.6中实现，因此它在Tcl 8.5中根本不起作用。我建议从opencircuitdesign.com获取魔法并从源代码编译，这通常在Linux系统上没有问题。 autoconf脚本应该能够找到Tcl版本8.6。

您也可以忽略qflow中的“display”选项并以交互方式运行magic。使用“lef read”命令读入标准单元格定义，然后使用“def read”从qflow读取路由布局。

Answer 2

这是一个已知的问题（也是一个非常讨厌的问题）来自某些OS版本的运行时链接程序，它们不希望链接包含对未知例程的引用的文件，即使该例程从未被调用过。在这种情况下，Tcl在没有Tk图形的情况下运行，因此基本Tcl对象库没有定义任何Tk例程，并且链接器在显示的第一个这样的例程（Tk_GetCursorFromData）上停止。出于某种原因，Fedora链接器（或者关于我的设置的东西）没有这样做，否则我很久以前就已经解决了这个问题。事实上，我最近才修复它，解决方案是最新版本的magic-8.1。由于你有Tcl / Tk 8.6，这个解决方案应该可行（该解决方案仅适用于Tcl / Tk 8.6）。您可以更新到最新的魔术版本8.1，或者您可以编辑文件magic.tcl（在源代码中，它是tcltk/magic.tcl.in，并且已安装，它是/usr/local/lib/magic/tcl/magic.tcl）。在第13行，将开关-lazy添加到加载命令：

load -lazy /usr/local/lib/magic/tcl/tclmagic.so

Answer 3

谢谢R. Timothy Edwards和Tim Edwards。你的答案很有帮助 我已经解决了这个问题。下周，我将在这里添加如何在ubuntu 14.04上为具有相同问题的用户解决此问题的分步指南：

Answer 4

magic- configure ...：./ configure --with-tcl = / opt / ActiveTcl-8.6 --with-tk = / usr / local / lib / tk8.6

qflow- configure ...：./ configure --with-magic = / usr / local / bin / magic

安装qflow后

sudo apt-get magic（它将下载魔法7.5，不包括覆盖魔法8.0，我们只需要.so文件）

打开/usr/local/lib/magic/tcl/magic.tcl（作为sudo）

并将第13行编辑为： load -lazy /usr/lib/x86_64-linux-gnu/magic/tcl/tclmagic.so
