Issue when building - /usr/bin/ld : cannot find -lXi

[Ramisay]

Hi,
I am trying to install OCE under Ubuntu 18.04, but I got a problem during the building.
First I cloned the directory from : git clone https://github.com/tpaviot/oce.git > /dev/null
Then I installed the 3dparty libraries. And finally when I run "cmake" it is working (even if it is not detecting the versions of Tcl and Tk) :

But I have a problem when running "make" command, when I run it it starts building until 17% where it shows a linking problem :

I was wondering what could be the solution to properly build and install OCE?
I am trying to install OEC in order to couple it with a software that I am using (Siconos).
Thanks in advance.

It seems you need to install libxi-dev. It's probably a newer dependency from a tracking a newer OCCT version that is not yet reflected in the docs.

[Ramisay]

Thank you @aothms , that was the problem, I didn't have libxi-dev in my laptop. Now It's working and OCE is installed.

In the other hand, I'm trying to install Python-occ now, and when I run the cmake commande , I get :

CMake Error at CMakeLists.txt:131 (find_package):
  By not providing "FindOCE.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OCE", but
  CMake did not find one.

  Could not find a package configuration file provided by "OCE" (requested
  version 0.18) with any of the following names:

    OCEConfig.cmake
    oce-config.cmake

  Add the installation prefix of "OCE" to CMAKE_PREFIX_PATH or set "OCE_DIR"
  to a directory containing one of the above files.  If "OCE" provides a
  separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred!

Is "OCEConfig.cmake" should be generated automatically when we install OCE? or there is a way to generate it? and how to specify it when we run cmake commande during OCC building?
Thanks in advance.

[Ramisay]

In fact , I solved the last problem by installing the " liboce-foundation-dev " library. and now cmake command works.
But unfortunetly, the make commande also prevents error messages, when I run make I got :

I have python3.6 on my computer, with oce and swig installed.
I am wondering what could be the problem in this case.

Thanks in advance.

[Ramisay]

I don't know if it could be a problem of cmake version or not, cause I'm using :
cmake --version
cmake version 3.10.2
is it ok for pyocc?

Best Regards.
