I get stuck at installing caffe.

I requires a GCC version < 5.

I did the following :

1)

• l kept my current gcc version : gcc version 8.2.0 (Debian 8.2.0-4)


• At the cmake step : cmake .. l comlied correclty


• But l run make -j

l get the error that : GCC < 5 is required

then l downgraded my gcc to version 4.8.5 (GCC) and l repeated the same process and l get stuck this time at cmake ..
The erro is as fllow :

CMake Error at /usr/share/cmake-3.12/Modules/FindBoost.cmake:2063 (message):

  Unable to find the requested Boost libraries.



  Boost version: 1.62.0

  Could not find the following Boost libraries:



          boost_system

          boost_thread

  Some (but not all) of the required Boost libraries were found.  You may

  need to install these additional Boost libraries.  Alternatively, set

  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT

  to the location of Boost.

These packages were correctly found when l run cmake wih gcc8.2 (but can run make -j because it requires gcc < 5) .

How can l solve that ?

It seems that cmake with gcc 4.8 can't find these above libraries .
