Install from source end up with tapacc #134

Open NeoYY opened 1 year ago

NeoYY commented 1 year ago

Hi, we follow the tutorial here, with option 2. However, after we finshed the Build and Installation, we ended up with a tapacc executable. Is that correct? What is the difference between tapac and tapacc? Thank you!

Blaok commented 1 year ago

Yes, that is correct. tapac is the "main" executable of TAPA. tapacc is a C++ source-to-source transformation tool, which is an internal component of TAPA and will be called from tapac as part of the compilation process.

In that case, if we cannot call tapac after installation, while can only call tapacc, that still means we messed up something during installation, is that correct? Otherwise, if tapacc is what we looking for after install from source, is there any document for specifically for tapacc that we can refer? Thank you!

Did you try https://tapa.readthedocs.io/en/release/installation.html#verify-installation

If tapac is still not found, make sure python3 -m pip install tapa/backend/python finished without error.

NeoYY commented 1 year ago

python3 -m pip install tapa/backend/python finished without errors. However, we are trying to install tapa into a server, and running both installation methods will install it into/.local/bin instead of /local/bin. This cause only the root user can call and access tapac without errors. Even if we link tapac from /.local/bin to /local/bin, it still causes a permission denied error on the user side. Do you have any tips for installing tapa on the server and granting all users access? Thank you!

Blaok commented 1 year ago

If you would like to install tapac for all users, please run python3 -m pip install tapa/backend/python as root. The tapac executable should appear as /usr/local/bin/tapac.

Fixed! Thank you!

  1. tapac --help => This command works fine. Thank you!

  2. I am trying to run a simple vadd example from (https://tapa.readthedocs.io/en/release/getting_started.html). These are the steps I followed git clone https://github.com/UCLA-VAST/tapa => Clonned the existing code code. I didnt modify any of the code cd tapa/apps/vadd g++ -o vadd -O2 vadd.cpp vadd-host.cpp -ltapa -lfrt -lglog -lgflags -lOpenCL => Compiled it. I get the following error. vadd_compile

Please let me know if you can help me with this issue. Again thank you and the team so much for all the back and forth

Can you try adding -std=c++17 to the compiler arguments?
