Installation without Root Access in Linux - c++

Question

I have to compile Locally Aware NMS (lanms) in my remote server LINUX based with an user account without root access.
In lanms there is a script named adapter.cpp , I have to convert it to .pyd so that it works with python. I have given the code described here.
#include "pybind11/pybind11.h"
#include "pybind11/numpy.h"
#include "pybind11/stl.h"
#include "pybind11/stl_bind.h"
#include "lanms.h"
namespace py = pybind11;
namespace lanms_adaptor {
std::vector<std::vector<float>> polys2floats(const std::vector<lanms::Polygon> &polys) {
std::vector<std::vector<float>> ret;
for (size_t i = 0; i < polys.size(); i ++) {
auto &p = polys[i];
auto &poly = p.poly;
ret.emplace_back(std::vector<float>{
float(poly[0].X), float(poly[0].Y),
float(poly[1].X), float(poly[1].Y),
float(poly[2].X), float(poly[2].Y),
float(poly[3].X), float(poly[3].Y),
float(p.score),
});
}
return ret;
}
/**
*
* \param quad_n9 an n-by-9 numpy array, where first 8 numbers denote the
* quadrangle, and the last one is the score
* \param iou_threshold two quadrangles with iou score above this threshold
* will be merged
*
* \return an n-by-9 numpy array, the merged quadrangles
*/
std::vector<std::vector<float>> merge_quadrangle_n9(
py::array_t<float, py::array::c_style | py::array::forcecast> quad_n9,
float iou_threshold) {
auto pbuf = quad_n9.request();
if (pbuf.ndim != 2 || pbuf.shape[1] != 9)
throw std::runtime_error("quadrangles must have a shape of (n, 9)");
auto n = pbuf.shape[0];
auto ptr = static_cast<float *>(pbuf.ptr);
return polys2floats(lanms::merge_quadrangle_n9(ptr, n, iou_threshold));
}
}
PYBIND11_PLUGIN(adaptor) {
py::module m("adaptor", "NMS");
m.def("merge_quadrangle_n9", &lanms_adaptor::merge_quadrangle_n9,
"merge quadrangels");
return m.ptr();
}
To convert it I have used the following command.
cl adaptor.cpp ./include/clipper/clipper.cpp /I ./include /I "C:\ProgramData\Anaconda3\include" /LD /Fe:adaptor.pyd /link/LIBPATH:"C:\ProgramData\Anaconda3\libs"
It shows an error:
Command 'cl' not found, but can be installed with:
apt install cl-launch
Please ask your administrator.
Furthermore, I don't have the root access. Is there any other way to install "cl" without administrator privileges?
The other way to compile lanms is need to install the g++ compiler in order to compile the adaptar.cpp file.
sudo apt-get install build-essential
It is also asking for the administrator privileges.

I'm afraid, that it is almost impossible to compile your code on a machine that doesn't have a compiler installed.
The best option, that I can come up with, would be to set up a virtual machine, that runs the same version of the same linux distribution as the server. In that virtual machine, you have root access and can install a compiler. After compiling the code you just copy the program/library to the server. It is however not guaranteed, that the program compiled in the virtual machine will run without problems on the real server.
