FemtoRV/TOOLS/get_symbiflow.sh: fix env create #46

Closed trabucayre closed 3 years ago

trabucayre commented 3 years ago

get_symbiflow.sh is based on install instructions provided by symbiflow-examples repository. By using this script an error appear with:

$INSTALL_DIR/$FPGA_FAM/conda/bin/conda env create -f $FPGA_FAM/environment.yml
EnvironmentFileNotFound: '/somewhere/learn-fpga/FemtoRV/TOOLS/xc7/environment.yml' file not found

In getting-symbiflow.html, the authors consider that users execute commands at the root directory of symbiflow-examples. So $FPGA_FAM/environment.yml is not a path related to INSTALL_DIR but to the current directory and refers to https://github.com/SymbiFlow/symbiflow-examples/blob/master/xc7/environment.yml

This PR add two wget calls: one for environment.yml and one for requirements.txt refered by the former. conda env create line is adjusted to use yml file located in current directory instead of xc7 subdirectory
