Ubuntu 16.10 下安装Caffe遇到： “未定义引用” 问题
解决办法：
Hi all,
Thanks for the thread. I just install 15.10 and this saved me from a lot of troubles.
With the latest version 15.10.1, only hacking CUDA is not enough. The error is because google-glog got built with -D_GLIBCXX_USE_CXX11_ABI=0 while everything else use the default option!
This is also the cause of the error that Locke Lee haveshown.
I have made a full guide, (feel free to correct my English :D)
///////////////////////////////////////////////////////
1. HACK CUDA
+As all other packages in ubuntu 15.10 is built with GCC 5(.2) but CUDA (7.5) not allow >4.9 gcc version!
+We would like to "hack" CUDA to compile cuda files with gcc-5 as follows:
a) sudo gedit /usr/local/cuda/include/host_config.h
b) change line 113 to #if __GNUC__ > 5 || (__GNUC__ == 5 && __GNUC_MINOR__ > 2)
///////////////////////////////////////////////////////
2. FIX google-glog
+Some bad guys build google-glog with wrong gcc abi config! And the wrong build is in
the official repository. Fack!
+i.e when all other package is built with -D_GLIBCXX_USE_CXX11_ABI=1 (default). They built it with
-D_GLIBCXX_USE_CXX11_ABI=0! We need to built it ourself!
a)
sudo apt-get remove libgoogle-glog-dev libgoogle-glog0v5
cd ~ //other folder is ok
apt-get source libgoogle-glog-dev
cd google-glog-0.3.4
./configure
b) The generated makefile have some mistakes (?)
- change line 613 to ACLOCAL=aclocal-1.15
- change line 619 to AUTOMAKE=automake-1.15
c)
make // this will have some errors, dont worry
automake --add-missing
make -j 16 //or 100,whatever
sudo make install
//////////////////////////////////////////////////////////
Now we can build caffe! Profit!
2 **！！！！如果 遇到：：：error: version mismatch. This is Automake 1.15.1,
