issue with pulp build

[sungyong]

Hello, pulp community

i have some issue on build pulp, (i just succeed pulpissimo, then i'm trying to build pulp)

https://github.com/pulp-platform/pulp

i trying to build pulp with above link. But when i command "make build"

it makes error 

Makefile:30: warning: overriding recipe for target '/root/pulp/sim/tcl_files/config/vsim_ips.tcl'
Makefile:30: warning: ignoring old recipe for target '/root/pulp/sim/tcl_files/config/vsim_ips.tcl'

make[1]: *** [Makefile:57: lib] Error 1
make[1]: Leaving directory '/root/pulp/sim'
make: *** [Makefile:120: build] Error 2



in some communities, they said commented "rm modelsim.ini"
so i make that code commented

then it has error

how can i fix it? the error vlog-12110, i think its problem of questasim.

How about second one? why they find design unit tb_pulp?

Using the Altera/Intel starter edition of Model/Questasim was known to cause issues. This might be related, note that the scripts are for the 'proper' version of Questasim. I do not know if the starter edition accepts all options.

Hello, I encountered the same issue as you and also tried removing the last line, but it didn’t resolve the problem. Additionally, I tested with two versions of QuestaSim: 2021.2 and 10.7c, but the issue persists. Have you managed to resolve the error?

i think  pulp github does not updated few years. so i expect that pulpissimo in pulp would not support these day's versions. (pulpissimo has been updated in these days, but not in pulp)

i try again soon.

Thank you very much for your response! I accidentally discovered that the

Code:

make build

command doesn’t need to execute successfully; you just need to run the following commands instead:
bash
复制代码

Code:

git clone https://github.com/pulp-platform/regression_tests.git 
git clone https://github.com/pulp-platform/pulp-runtime.git 
source pulp-runtime/configs/pulp.sh 
export PATH=*path to riscv gcc toolchain*/bin:$PATH 
export PULP_RISCV_GCC_TOOLCHAIN=*path to riscv gcc toolchain* 
cd regression_tests/hello 
make clean all run gui=1 

The only thing to note is that if your system has two versions of the toolchain installed, you must pay attention to their path settings.
For example, I first installed Pulpissimo and successfully ran it using riscv-gnu-toolchain, which was installed under  /opt/riscv
. The path settings were also configured accordingly.
However, when I tried to install Pulp, I used  pulp-riscv-gnu-toolchain, which was installed in a different location. But I didn’t update my PATH
or run bash：

Code:

export PATH=*path to riscv gcc toolchain*/bin:$PATH 
export PULP_RISCV_GCC_TOOLCHAIN=*path to riscv gcc toolchain* 

This caused the issue.
