[英]wxMkdir on Ubuntu
I try to use wxMkdir function to create a new directory in my c++ program. 我尝试使用wxMkdir函数在我的c ++程序中创建一个新目录。 The directory
/home/test/Documents/MATLAB/mydata/demo
already exists. 目录
/home/test/Documents/MATLAB/mydata/demo
已存在。 But the following code 但是下面的代码
wxString dataDirectory = wxT("/home/test/Documents/MATLAB/mydata/demo/A");
if(! wxDirExists(dataDirectory))
{
wxMkdir(dataDirectory);
}
will pop up a runtime error dialog saying that 将弹出一个运行时错误对话框,指出
Directory '/home/test/Documents/MATLAB/mydata/demo/A' couldn't be created (error2: No such file or directory)
无法创建目录“ / home / test / Documents / MATLAB / mydata / demo / A”(错误2:无此类文件或目录)
and the directory A
under directory demo
will not be created. 并且不会创建目录
demo
下的目录A
However, if I change the desired directory to /home/test/Documents/MATLAB/mydata/A
, everything works. 但是,如果我将所需的目录更改为
/home/test/Documents/MATLAB/mydata/A
,则一切正常。
So is there a maximum directory depth for wxMkdir in the Ubuntu implementation of wxWidgets? 那么在wxWidgets的Ubuntu实现中wxMkdir的目录深度最大吗? This problem is not seen under Mac, however.
但是,在Mac下看不到此问题。 I searched the web and couldn't get anything meaningful.
我在网上搜索,没有任何有意义的信息。 Anyone has a better idea?
有人有更好的主意吗?
If mkdir
fails with a "No such file or directory" error, it usually means that the parent directory doesn't exist (or is a dangling symlink). 如果
mkdir
失败并显示“没有这样的文件或目录”错误,则通常表示父目录不存在(或是悬空的符号链接)。 Presumably the same would apply to wxMkdir
. 大概对
wxMkdir
同样适用。
Does /home/test/Documents/MATLAB/mydata/demo
already exist? /home/test/Documents/MATLAB/mydata/demo
已经存在? And just to be sure, is it a directory? 只是要确定,它是目录吗?
(If that's not the problem, I'll delete this answer and add it as a comment.)
(如果这不是问题,我将删除此答案并将其添加为评论。)
