Question

我在使用python解释器的c可执行文件中遇到了一些问题。由于某种原因，它无法加载<fullpath>Tix843.dll。但是当直接运行python代码（来自python）时，它确实有效。 dll的路径/名称是正确的...... 使用依赖walker我只看到Tkinter尝试加载tix dll但无法找到它...

在tcl中跟踪所有类型的路径后，我只能检测到1个差异：nameofexecutable。当直接从python运行时，它是python.exe的路径，但是从我的c可执行文件运行它时（显然）是path/name of the executable。

在tcl / tk中，我注意到nameofexecutable用于设置很多路径，所以我认为这会导致我的问题。

我试图阻止这个问题：

将dll的路径添加到系统路径
将dll的路径添加到$auto_path - ＆gt;没有变化
在调用PySys_SetArgv之前设置c可执行文件的argv[0] - ＆gt;没有变化

我做了些蠢事，或者如何设置nameofexecutable？有没有其他方法可以解决这个问题。

编辑：再次使用依赖性walker进行检查，现在我已经转发了没有任何线索发生了什么... 结果如下：

所以它可以找到dll一些但不总是然后失败

Answer 1

{T}库初始化期间设置nameofexecutable属性（从Tcl_FindExecutable()的参数派生，我不知道究竟是怎么调用的，但绝对是：它用于做各种各样的的东西）。您无法在任何其他位置设置它。但是，Tcl实际上并没有使用那个你无法覆盖的值。

相反，您应该考虑将TCLLIBPATH环境变量设置为Tcl目录列表以搜索包定义。或者您可以将目录添加到Tcl内的auto_path全局变量中（使用{ {1}}）包含实际要查看的地方列表（嗯，它实际上也在该变量中列出的地方的直接子目录中查找）。当然，这必须在你尝试加载Tix之前完成。

Answer 2

很可能，C程序找不到Tix.dll，因为它不在您的路径中。 Python可以找到它，因为它与python可执行文件位于同一目录中，或者在python知道的子目录中。尝试将dll路径添加到PATH环境变量。
