Fatal error : kppfile.tmp: Can't read file

[lmc5474]

Bug Report
Description
When using the example provided with kpp for testing, running cd example followed by the kpp ros.kpp command results in the error Fatal error: kppfile.tmp: Can't read file. This error is caused by the missing kppfile.tmp file. Creating a new kppfile.tmp file in the folder allows the command to run, but the result is incorrect. For example, the generated small_strato_Integrator.f90 file does not contain any code.

Steps to Reproduce
Steps to reproduce the behavior:

Clone or download the kpp repository.
Navigate to the example directory: cd example.
Run the command: kpp ros.kpp.
Observe the error message: Fatal error: kppfile.tmp: Can't read file.
Expected Behavior
kpp should run normally and generate the correct output files.

Actual Behavior
The missing kppfile.tmp file causes an error. Creating a new kppfile.tmp file in the folder allows kpp to run, but the generated small_strato_Integrator.f90 file does not contain any code, resulting in an incorrect output.

Screenshots

Environment

Operating System:Centos7
kpp Version: 3.1.1
Additional Information
Creating a new kppfile.tmp file allows kpp to run, but the generated small_strato_Integrator.f90 file does not contain any code, resulting in incorrect output.

Thanks for writing @lmc5474. I did the same steps on an Ubuntu instance but I didn't run into this problem.

I've seen this error message before on a virtual machine which did not
have enough memory (RAM). I suggest to increase the memory of the VM and
try again.
