compiling error

[wsnooker]

I installed boost but also an error occured in compiling, as follows:

cmake -DEIGEN_ROOT=../../eigen-3.3.1/ -DBOOST_ROOT=/usr/include/boost/ ..
-- Boost version: 1.54.0
-- Could NOT find Boost
-- Configuring done
-- Generating done
-- Build files have been written to: /home/ww110750/CTranslate/build

[guillaumekln]

Did you install boost system-wide? If so, you don't need to set -DBOOST_ROOT.

[wsnooker]

I did it system-wide, and the error existed anyway. But how to check where boost used in CTranslate or Makefile? A little hard unix problem maybe.

[wsnooker]

I reinstalled libboost, sudo apt-get install libboost-all-dev. The boost maybe found by cmake, but the output libonmt.so & cli/translate were not generated.

Command & cmake info as follows:

root@35f78adae197:/home/ww110750/CTranslate/build# cmake -DEIGEN_ROOT=../../eigen-3.3.1/ ..
-- Boost version: 1.54.0
-- Boost version: 1.54.0
-- Found the following Boost libraries:
-- program_options

-- Generating done
-- Build files have been written to: /home/ww110750/CTranslate/build

Oh, you need to run make. I will add that to the README.

[wsnooker]

make failed, command & log as follows:

cmake -DEIGEN_ROOT=../../eigen-3.3.1/ ..

It seems that the eigen header files could not be found, but I check the required file exists in Eigen dir:

Are there any misconfiguration in the cmakefile?

[guillaumekln]

You should follow Eigen installation instructions first. You typically do that in Eigen source directory:

mkdir build && cd build
mkdir -p ~/lib/eigen
cmake -DCMAKE_INSTALL_PREFIX=~/lib/eigen ..
make install

Then you can set -DEIGEN_ROOT=~/lib/eigen when configuring CTranslate.

[wsnooker]

Oh, I followed Method 1. Installing without using CMake, just copy the Eigen header dir and it didn't work.
Now using the CMake installation method, compiling right. Thanks for your kindly help.
