How to add package or-tools? #3770

You need to add |
|
I hope someone can assist me in adding the library, or directly help me add it myself. |
Yes I know, I try For test, can using follow code: #include "ortools/linear_solver/linear_solver.h"
#include "ortools/linear_solver/linear_solver.pb.h"
namespace operations_research {
void RunTest(
MPSolver::OptimizationProblemType optimization_problem_type) {
MPSolver solver("Glop", optimization_problem_type);
MPVariable* const x = solver.MakeNumVar(0.0, 1, "x");
MPVariable* const y = solver.MakeNumVar(0.0, 2, "y");
MPObjective* const objective = solver.MutableObjective();
objective->SetCoefficient(x, 1);
objective->SetCoefficient(y, 1);
objective->SetMaximization();
solver.Solve();
printf("\nSolution:");
printf("\nx = %.1f", x->solution_value());
printf("\ny = %.1f", y->solution_value());
}
void RunExample() {
RunTest(MPSolver::GLOP_LINEAR_PROGRAMMING);
}
}
int main(int argc, char** argv) {
operations_research::RunExample();
return 0;

It's probably a link order issue, you probably have to add links to let xmake know in which order it should link them. |
This may be a large workload if manual linking is required, as it has many dependencies. I just started learning about xmake, maybe there are other solutions, maybe I made some mistakes? |
|
Check installdir/lib and add_links explicitly: xmake-repo/packages/b/brotli/xmake.lua Line 21 in 79a5f74 However, the package has some external dependencies that need to be added as well |
Its huge project can't be manual linking I guess. (ToT) |
|
You can try, for example, adding the packages that xrepo already has first package("or-tools")
set_homepage("https://developers.google.com/optimization/")
set_description("Google's Operations Research tools")
set_license("Apache-2.0")
add_urls("https://github.com/google/or-tools/archive/refs/tags/$(version).tar.gz",
"https://github.com/google/or-tools.git")
add_versions("v9.9", "8c17b1b5b05d925ed03685522172ca87c2912891d57a5e0d5dcaeff8f06a4698")
if is_plat("windows") then
add_configs("shared", {description = "Build shared library.", default = false, type = "boolean", readonly = true})
end
add_deps("cmake")
add_deps("zlib", "eigen", "re2")
add_deps("protobuf-cpp", {confgis = {zlib = true}})
on_install("windows", "linux", "macosx", function (package)
local configs = {
"-DBUILD_TESTING=OFF",
"-DBUILD_EXAMPLES=OFF",
"-DBUILD_SAMPLES=OFF",
"-DBUILD_DEPS=OFF",
"-DUSE_BOP=OFF",
"-DUSE_COINOR=OFF",
"-DUSE_SCIP=OFF",
}
table.insert(configs, "-DCMAKE_BUILD_TYPE=" .. (package:is_debug() and "Debug" or "Release"))
table.insert(configs, "-DBUILD_SHARED_LIBS=" .. (package:config("shared") and "ON" or "OFF"))
import("package.tools.cmake").install(package, configs)
end)
on_test(function (package)
assert(package:check_cxxsnippets({test = [[
#include <ortools/linear_solver/linear_solver.h>
void test() {
auto solver = MPSolver::CreateSolver("SCIP");
}
]]}, {configs = {languages = "c++20"}}))
end) |
OK, I will try it late, thank for you kindness help. |
It config success , but build error, when install or-tools. Maybe those deps'version need to specify？ |
Is your feature request related to a problem? Please describe.
I found that there are very few packages about Operations Research in xrepo, so I want to add google/or-tools.
I built the or-tools package myself, but encountered a problem. I hope someone can answer it.
It was installed successfully, but there were errors when using it.
Describe the solution you'd like
I added the package myself:
"BUILD_DEPS" means It can auto download requeaments itself by cmake.
The above can be successfully installed
But I get problem when I used, this is my project:
Its build error report:
Describe alternatives you've considered
No response
Additional context
