caffe cuda8.0 GTX1070安装问题总结

最近终于有了1070的显卡，可以尝试使用GPU进行训练，这里把安装caffe遇到的一些大坑以及解决方法进行一下汇总。

.build_release/lib/libcaffe.so: undefined reference to google ::protobuf...  

重新安装编译protobuf
参考：http://blog.youkuaiyun.com/fansetcool/article/details/51569374

在安装之前需要先把工具automake给装了：

sudo apt-get install autoconf automake libtool

那接下来就下载protobuf吧，在github下载，解压https://github.com/google/protobuf
解压后，进入目录protobuf-master, 运行：

./autogen.sh

这时会提醒你的curl没有安装的错误。所以安装curl，再从https://googlemock.googlecode.com/files/gmock-1.7.0.zip直接下载（翻墙下载）。下完后不用解压，直接把gtest-1.7.0.zip放到protobuf-master的目录下就ok了。vim打开autogen.sh 把有用到curl的地方注释掉就ok了。然后再次运行./autogen.sh。
运行成功后，依次输入命令（还是在protobuf-master的目录下）：

 ./configure
make
make check

make跟make check都会费一点时间（如果你遇到很多次坑，每次都想重新编译protobuf的话记得make之前要make clean一下）。
最后

sudo make install

CXX/LD -o .build_debug/tools/device_query.bin
CXX/LD -o .build_debug/tools/upgrade_net_proto_binary.bin
.build_debug/lib/libcaffe.so: undefined reference to `google::base::CheckOpMessageBuilder::NewString()'
collect2: error: ld returned 1 exit status
Makefile:616: recipe for target '.build_debug/tools/upgrade_net_proto_binary.bin' failed
make: *** [.build_debug/tools/upgrade_net_proto_binary.bin] Error 1

.build_debug/tools/compute_image_mean.o: In function `std::string* google::MakeCheckOpString<int, int>(int const&, int const&, char const*)':
/usr/include/glog/logging.h:672: undefined reference to `google::base::CheckOpMessageBuilder::NewString()'

重新安装手动编译glog,gflags，lmdb等
1）卸载

sudo apt-get remove libgoogle-glog-dev libgoogle-glog0v5
sudo apt-get remove libgflags-dev liblmdb-dev

2)安装glog

wget https://github.com/google/glog/archive/v0.3.4.tar.gz
tar zxvf v0.3.4.tar.gz
cd glog-0.3.4
./configure

进入glog-0.3.4，编辑makefile。

change line 613 to ACLOCAL=aclocal-1.15
change line 619 to AUTOMAKE=automake-1.15

保存退出

make 
automake --add-missing
make -j 8
sudo make install

其中make这一步遇到error没关系。
3）安装gflags

wget https://github.com/schuhschuh/gflags/archive/master.zip
unzip master.zip
cd gflags-master
mkdir build && cd build
export CXXFLAGS="-fPIC" && cmake .. && make VERBOSE=1
make
sudo make install

4)安装lmdb

git clone https://github.com/LMDB/lmdb
cd lmdb/libraries/liblmdb
make
sudo make install

3.

.build_release/lib/libcaffe.so：对‘leveldb::DB::Open(leveldb::Options const&, std::string const&, leveldb::DB**)’未定义的引用
.build_release/lib/libcaffe.so：对‘leveldb::Status::ToString() const’未定义的引用

重装leveldb

1）卸载

sudo apt-get remove libleveldb-dev

2）下载leveldb

wget https://github.com/google/leveldb/archive/v1.19.zip
unzip v1.19.zip && cd leveldb-1.19/
make
cd out-shared/ 
sudo mv libleveldb.* /usr/local/lib
cd
cd leveldb-1.19/include/
sudo cp -R leveldb /usr/local/include
sudo ldconfig

Makefile:532: recipe for target 'runtest' failed
make: *** [runtest] 段错误 (core dumped)

这个是make runtest时出现的，之前的make all 以及make test都成功了，查了好多资料都没解决，不过貌似影响不大，我忽略了这个错误，后面caffe好像也能正常运行。。。以后找到解决方法时再补。。。
