With Vivado installed you should setup the tools like (change for your Vivado install path):
source /path/to/Xilinx/Vivado/2019.2/settings.sh

You can check that one of the required environment variables is set like:
echo $XILINX_VIVADO

Then during the logging of the example you should see a message like:
DEBUG:conifer.utils.misc:Including ap_ headers from XILINX_VIVADO: -I/path/to/Xilinx/Vivado/2019.2/include

Greetings I used the same command line 'source /path/to/Xilinx/Vivado/2019.2/settings.sh' but still getting the same error. Any help i can get from this

522 if ap_include is None:
523 os.chdir(curr_dir)
--> 524 raise Exception("Couldn't find Xilinx ap_ headers. Source the Vivado/Vitis HLS toolchain, or set XILINX_AP_INCLUDE environment variable.")
525 cmd = f"g++ -O3 -shared -std=c++14 -fPIC $({_py_executable()} -m pybind11 --includes) {ap_include} {gcc_opts()} bridge.cpp firmware/BDT.cpp firmware/{cfg.project_name}.cpp -o conifer_bridge{self._stamp}.so"
526 logger.debug(f'Compiling with command {cmd}')

Exception: Couldn't find Xilinx ap_ headers. Source the Vivado/Vitis HLS toolchain, or set XILINX_AP_INCLUDE environment variable.

@Andre-coder

Could you run the following and report back what is says?

import sys
import logging
logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)
import conifer
conifer.utils._ap_include()

Can you check that the path that your sourced the settings from is correct?

Its running fine now, the conifer can find the Xilinx on my env. Thank You!

But theres an error that also encounter during the execution on i will share it

529 if ret_val != 0:
530 raise Exception(f'Failed to compile project {cfg.project_name}')
531 except:

Exception: Failed to compile project my_prj

During handling of the above exception, another exception occurred:

Can you please share more of the error message?

Greetings! Is there any insights that can help fix this error. @thesps . I was able to get the build() function runing without any issue, but the exception showing up in the 533, does it affect on the build function also?

@thesps I found the solution for this particulary error, the compilation was failing due the gcc-gcc++ lib dev, for fedora user i add to move files from (sudo cp /usr/include/c++/13/i686-redhat-linux/bits/os_defines.h /usr/include/c++/13/bits) and python3-devel dependecies. Thank You!
