我将在 Gem5-gpu 模拟器上编译 Rodinia 基准测试，当我让它抱怨 gcc-4.4 并给我以下错误：
make gem5-fusion
make -f Makefile.gem5-fusion
make[1]: Entering directory '/home/hodjat91/Desktop/gem5-gpu/benchmarks/rodinia/backprop'
gcc-4.4 -DOUTPUT -O3 -I../../../gem5/util/m5 -I../../libcuda -I/usr/local/cuda//include -I/home/hodjat91/NVIDIA_GPU_Computing_SDK/C/common/inc/ -L/home/hodjat91/NVIDIA_GPU_Computing_SDK/C/lib -g -c facetrain.c -o facetrain.c_o
make[1]: gcc-4.4: Command not found

make[1]: Leaving directory '/home/hodjat91/Desktop/gem5-gpu/benchmarks/rodinia/backprop'

我的系统上有 gcc 5.3。
谢谢

获取 g++-4.4 / gcc-4.4 ：gedit /etc/apt/sources.list
然后在文件中添加两行新行：
deb [URL] trusty main universe
deb [URL] trusty-updates main universe
我的例子：
deb http://dk.archive.ubuntu.com/ubuntu/ trusty main universe
deb http://dk.archive.ubuntu.com/ubuntu/ trusty-updates main universe
运行sudo apt-get update，就可以安装 gcc-4.4 ：sudo apt-get install g++-4.4
