Fix build with Intel C++ compiler
icx --version: Intel(R) oneAPI DPC++/C++ Compiler 2022.0.0 (2022.0.0.20211123)
Disable fast maths to:
- Fix warnings about std::isnan(), etc. being evaluated to false, due to
-ffast-math being enabled
- Fix failures in regression test suite
How to reproduce:
docker pull intel/oneapi-basekit
docker run --rm -it -v $HOME:$HOME intel/oneapi-basekit
apt update
apt install sqlite3 libsqlite3-dev libcurl4-gnutls-dev libtiff-dev
CC=icx CXX=icx cmake .. -DCMAKE_EXE_LINKER_FLAGS=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
