fuzzer does not run

[KiranKanchi]

Dear team,

I am setting up the symbiflow for the first time and I have issue in step 9.

After step 8: ./download-latest-db.sh

Pick a fuzzer (or write your own) and run:

cd fuzzers/010-clb-lutinit
make -j$(nproc) run

---

make run results in :

make clean

Any pointers on what could be wrong ? Thank you very much in advance.

Kind regards,

Look like you skipped step 6 (sourcing the environment). Nevertheless, these scripts should probably be set -eu so they don't accidentally cause major problems in cases like this.

Hello Xiretza,

Thank you for your kind reply, i repeated the steps and see the same error. Here is my history:

838 sudo make build
839 source settings/artix7.sh
840 make db-prepare-artix7
841 sudo make db-prepare-artix7
842 sudo ./download-latest-db.sh
843 cd fuzzers/010-clb-lutinit/
844 sudo make -j12 run

I am not sure where am i going wrong.

Kind regards,
KiranKanchi

Why are you trying to do any of this as root? sudo strips the environment for security reasons.

[KiranKanchi]

ah! I bypassed your root check earlier because I could not figure out how to proceed as non root user. i will restore it back and figure out to run without root. thank you very much again!

[KiranKanchi]

I created a new user and followed the same steps* and there are no problems.
*Note: I had to go to step 7 first and then do step 6.

Kind regards,
KiranKanchi
