I am trying to get started with PULP, however I get the message above when I run make build or make clean build. This happened on two different machines, one that used modelsim and one that used questasim. What should I do?

I've got the same issue as well even though that pulpissimo's make build works just fine.

Hello @lzeltser,
I managed to solve this problem by editing the file (pulp/sim/Makefile) where I commented the last line in the file rm modelsim.ini and then ran again make build.

Type the following command: export IPAPPROX=1
Then start building it.It worked for me.

but next,

so the right way is delete rm modelsim.ini ,copy a right modelsim.ini in the file(pulp/sim) ,such as /questasim/modelsim.ini
then ,success
