#2553: Cactus' link command uses CPPFLAGS and CXXFLAGS
Reporter: Roland Haas Status: open Milestone: Version: development version Type: bug Priority: minor Component: Cactus
Comment (by Erik Schnetter):
I didn’t realize you had trouble compiling these thorns.
For me, these settings work:
```shell CXX = /home/eschnetter/Cactus/view-cuda/bin/nvcc --compiler-bindir /home/eschnetter/Cactus/view-cuda-compilers/bin/g++ -x cu CXXFLAGS = -pipe -g --compiler-options -march=native -std=c++17 --compiler-options -std=gnu++17 --expt-relaxed-constexpr --extended-lambda --gpu-architecture sm_75 --forward-unknown-to-host-compiler --Werror cross-execution-space-call --Werror ext-lambda-captures-this --relocatable-device-code=true --objdir-as-tempdir ```
with standard Cactus. This uses `nvcc` for all C++ code as well as for linking.
