Derlemeyi hızlandırmak için ccache kullanmak istiyorum .
Karşılaştığım ccache'yi nasıl etkinleştiririm? .
Şimdiye kadar yaptığım şey bu:
$ sudo apt-get install -y ccache
$ dpkg -l ccache
ii ccache 3.1.6-1 Compiler cache for fast recompilation of C/C++ code
$ whereis ccache
ccache: /usr/bin/ccache /usr/lib/ccache /usr/bin/X11/ccache /usr/share/man/man1/ccache.1.gz
Dosyama ccache
ekleyerek yola ekledim ~/.bashrc
:
$ export PATH="/usr/lib/ccache:$PATH"
$ source ~/.bashrc
$ echo $PATH
/usr/lib/ccache:/usr/local/cuda-5.5/bin/:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
Sembolik linkler iyi görünüyor:
$ ll /usr/lib/ccache/

Bağlantı iyi görünüyor:
$ which g++
/usr/lib/ccache/g++
$ make
g++ -o affine_euler affine_euler.cpp -O3 -DEIGEN_NO_DEBUG -I/usr/include/eigen3
g++ -o test_eigen test_eigen.cpp -O3 -DEIGEN_NO_DEBUG -I/usr/include/eigen3
Ancak önbellek boş:
$ ccache -s
cache directory /home/dell/.ccache
cache hit (direct) 0
cache hit (preprocessed) 0
cache miss 0
files in cache 0
cache size 0 Kbytes
max cache size 1.0 Gbytes
Ben nerde hatalıyım?
