There is a problem. After installing graphar in the system using this
method, if you then install arrow in the system and then rely on both arrow and
graphar in a program, the compilation will throw an error about multiple
definitions.
### install graphar
```bash
cmake .. -DBUILD_ARROW_FROM_SOURCE=ON -DGRAPHAR_BUILD_STATIC=ON
make -j && sudo make install
```
### install arrow
```bash
cmake .. -DARROW_PARQUET=ON -DARROW_CSV=ON -DARROW_JSON=ON -DARROW_ORC=ON
-DARROW_DATASET=ON -DARROW_BUILD_SHARED=OFF -DARROW_DEPENDENCY_USE_SHARED=OFF
sudo make install
```
### show.cc
```c++
#include "graphar/graph_info.h"
#include "iostream"
#include "arrow/api.h"
int main() {
std::string path =
"/workspaces/incubator-graphar/testing/neo4j/MovieGraph.graph.yml";
auto graph_info = graphar::GraphInfo::Load(path);
std::cout << graph_info.value()->Dump().value() << std::endl;
arrow::Int8Builder int8builder;
}
```
### CMakeLists.txt
```cmake
cmake_minimum_required(VERSION 3.15)
project(show)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -Wall")
set(TARGET show)
find_package(OpenSSL REQUIRED)
find_package(graphar REQUIRED)
find_package(Arrow REQUIRED)
add_executable(${TARGET} show.cc)
target_link_libraries(${TARGET} PRIVATE graphar Arrow::arrow_static)
```
### build show
```bash
cmake .. && make
```
