Pertama:
sudo apt-get install beignet opencl-headers
Tambahkan folder beignet ke jalur pencarian perpustakaan Anda:
sudo su
echo "/usr/lib/beignet/" > /etc/ld.so.conf.d/beignet.conf
ldconfig
exit
Dapatkan biner uji sederhana:
git clone https://github.com/vpereira/CapsBasic-beignet
Edit makefile agar terlihat lebih seperti ini:
all: capsbasic
capsbasic: capsbasic.cpp Makefile
g++ capsbasic.cpp -lcl -ocapsbasic -I/usr/include -L/usr/lib/beignet
clean:
rm -f capsbasic
Ini dia. OpenCL working-ish untuk keluarga kartu video HD intel ...
