1. Fetch numfocus-round2 for lfortran branch from here. Do a clean build of lfortran after checking out to numfocus-round2.
2. Fetch master-lfortran for stdlib branch from here. Check out to master-lfortran.
3. Run, FFLAGS=“--non-symtab-only” FC=lfortran cmake . inside stdlib.
4. Run, make. You should be able to see the following logs,

This report summarizes the work done in my GSoC 2021 project, Supporting Arrays and Allocatables in LFortran wth LFortran. A step by step development of the project is available at czgdp1807.github.io.

About Me

I am a final year Bachelor of Technology student at Indian Institute of Technology, Jodhpur in the department of Computer Science and Engineering.

Project Outline

This project aimed to add support for arrays and allocatables in LFortran. There were some miscellaneous goals as well, such as improving support for pointers and kinds and some bug fixes discovered along the way. The original plan of the project is listed as follows,
