Run fails: 'Failed to open file 'qelib1.inc'

Hi,

you can find the missing file in the Qiskit repo. You have to place it in the working directory from where you start the executable and it should work fine.

Cheers,

Hi, thanks, I thought I had posted a follow up for this issue.
I found the missing file in the examples folder, in this repo. It worked.

The funny this is, previously I tried to use the qelib1.inc present in Qiskit-Terra, and it failed, with a token related error message...

The current version does not work alone without ibm qiskit ?

The current version works without IBM Qiskit. The executable has to be launched from a directory that includes the qelib1.inc file with the definition of gates like h, t, ...

Do you mean that anyway the file "qelib1.inc" should be placed ?
I remember an earlier version correctly worked without the file.

You have to place the file in the directory from which you start the program if the .qasm file you try to map a .qasm file that contains the statement include "qelib1.inc";. If you do not have an include statement, the file is obviously not needed. The file can be found in the folder examples of this repository.

Thank you, azulehner.

So far I had tested your earlier version which works well as stand alone without the file.
(To be honest, I do not know the previous version really does not require the file, but I didn't check the file to run your mapper.)

Recently, I recognized that a new version was uploaded.
When I tested it, some error with the file happened. (Still, the previous version works well in the same laptop.)
In this regards, I have asked.
