Unknow system error when using cmake-gui

Rufus7 November 8, 2019, 8:11pm 1

Few days ago, I used cmake to configure a package and it worked fine. But for some reason I need to uninstall this package and install it all over again. So I run these commands under /build:

$sudo make uninstall
$sudo make clean

then I removed /build and the whole package file.

after that, I git the new package on the github and tried to install it.

And the problem occurred when I tried to use cmake-gui to configure the package I just downloaded.

The error message pop up in gui is:

System is unknown to cmake, create:
Platform/sh: 0: getcwd() failed: No such file or directory
Linux to use this system, please send your config file to cmake@www.cmake.org so it can be added to cmake
Your CMakeCache.txt file was copied to CopyOfCMakeCache.txt. Please send that file to cmake@www.cmake.org.
CMake Error at CMakeLists.txt:41 (message):
Unsupported operating system. Only Windows, Mac and Unix systems
supported.

and the CMakeError.log:

and the CMakeCache.txt as follow:

This is the CMakeCache file.
For build in directory: /home/rongqi/openpose/openpose/build
It was generated by CMake: /usr/bin/cmake
You can edit this file to change values found and used by cmake.
If you do not want to change any of the values, simply exit the editor.
If you do want to change a value, simply edit, save, and exit the editor.
The syntax for the file is as follows:
KEY:TYPE=VALUE
KEY is the name of a variable in the cache.
TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.
VALUE is the current value for the KEY.

system that I used:

ubuntu 16.04.12

cmake version 3.5.1

GNU Make 4.1
Built for x86_64-pc-linux-gnu

cmake-gui: cmake-qt-gui

Question:

1.what happened to the package so that cmake cannot recognize my system.(cmake works fine before I remove the package file and downloaded it again)
2.How to solve this problem

If more information is needed, please feel free to reply and ask.

Thanks in advance

You removed /build (and presumably recreated it), but did you get the shell you ran CMake from to use that new directory? I think this is what you saw:

Shell 1 (with sequence points for Shell 2):

$ mkdir foo
# seq1
$ rmdir foo
# seq2

# seq1
$ cd foo
# seq2
$ touch bar
touch: cannot touch 'bar': No such file or directory

This is because the cwd of the second shell was removed.

Thank you for your reply!
Since I have moved on to another project, I will look at that when the error pop again.

Thanks again!
