I have a problem with running gtest using cmake. This started after I changed the project structure, dividing the code into several modules with separate CMakeList.txt files. When I had one CmakeList without a static library, everything works fine.
Now I have this project structure:
├── src
│ ├── core
│ │ ├── bot.cpp
│ │ ├── bot.h
│ │ ├── domain.h
│ │ ├── geometry.h
│ │ ├── memory_reader.cpp
│ │ ├── memory_reader.h
│ │ ├── process_tools.cpp
│ │ ├── process_tools.h
│ │ └── CMakeLists.txt
│ └── main.cpp
├── test
│ ├── bot_test.cpp
│ ├── geometry_test.cpp
│ └── CMakeLists.txt
└── CMakeLists.txt

With this structure I can run main-bot target without any problem, but if I run the target with tests I get the following errors:

If I understand correctly, the problem is that geometry.h is compiled into the core library and also used as an include, but I can’t understand how this can be fixed.
The geometry.h file itself looks like this, but I don’t think that problem in it:
#pragma once
#include "domain.h"
#include <algorithm>
#include <vector>
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/geometries.hpp>
namespace zuma_bot::geometry {
namespace detail {
namespace bg = boost::geometry;
typedef bg::model::point<float, 2, bg::cs::cartesian> point_t;
typedef bg::model::linestring <point_t> linestring_t;
typedef bg::model::multi_point <point_t> mpoint_t;
linestring_t createLine(std::vector<Coord> line) {
linestring_t ls;
std::for_each(line.begin(), line.end(), [&ls](Coord c) {
bg::append(ls, point_t(c.x, c.y));
});
return ls;
}
}
std::vector<Coord> Intersection(const std::vector<Coord> &line_1, const std::vector<Coord> &line_2) {
using namespace detail;
linestring_t ls_1 = createLine(line_1);
linestring_t ls_2 = createLine(line_2);
mpoint_t out;
bg::intersection(ls_1, ls_2, out);
std::vector<Coord> result;
result.reserve(out.size());
std::for_each(out.begin(), out.end(), [&result](point_t p) {
result.push_back({p.get<0>(), p.get<1>()});
});
return result;
}
} // zuma_bot::geometry;
And how it is used in tests (geometry_test.cpp):
#include <vector>
#include <gtest/gtest.h>
#include "geometry.h"
using namespace zuma_bot;
using namespace zuma_bot::geometry;
using namespace std;
TEST(Intersection, Intersection_1) {
vector<Coord> line_1{{0, 0}, {0, 5}};
vector<Coord> line_2{{1, 1}, {-1, 1}};
auto result = Intersection(line_1, line_2);
ASSERT_EQ(result.size(), 1);
EXPECT_EQ(result[0], (Coord{0, 1}));
}
TEST(Intersection, Intersection_2) {
vector<Coord> line_1{{0, 0}, {0, 5}};
vector<Coord> line_2{{0, 0}, {-1, 1}};
auto result = Intersection(line_1, line_2);
ASSERT_EQ(result.size(), 1);
EXPECT_EQ(result[0], (Coord{0, 0}));
}
...
If you need full project here
I tried to separate the header files of the library into a another target, and also use target_include_directories differently, but I just got more confused(
