Linux compilation help -- vcpkg configuration

Support
1

Heyo,

I’m looking to compile beammp for linux following the docs here: docs.beammp.com - getting started But I’m getting caught up on the cmake compilation using vcpkg.

The furthest I’ve gotten is cmake configuring with a warning, and failing to build. I have installed a vcpkg entry to /usr/local/apps/vcpkg, and as far as I can tell configured it? I’m mostly just used to building on rhel without vcpkg, so I’m a bit out of my depth here.

I’ve used vcpkg to provide httplib, which cmake was complaining about. I did this by setting VCPKG_ROOT appropriately and running vcpkg install cpp-httplib, that issue seems to have been resolved. At this point it seems to be a makefile issue, and I don’t really know how to fix that.

I’m building v2.4.0 on popos 22.4 LTS, vcpkg is just running latest per Microsoft’s docs*. The output of the (slightly modified as I don’t have any vcpkg in my home dir) commands from the docs is below.

*As a new user I can only put one link, but I’m using their " Install and use packages with CMake" which has a vcpkg installation section at the top.

zulu@pop-os:/usr/local/apps/beammp$ cmake -DCMAKE_BUILD_TYPE=Release . -B bin -DCMAKE_TOOLCHAIN_FILE=../vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux

Any help as to how to configure vcpkg, or any installation dependencies I could be missing would be appreciated.

DO NOT, I REPEAT, DO NOT DOWNLOAD VCPKG AS A PACKAGE.
CLONE IT. USE THAT AS THE TOOLCHAIN PATH.

use the path for “DCMAKE_TOOLCHAIN_FILE=” of where you cloned vcpkg to, e.g. ~/Downloads/:

cd Downloads
git clone https://github.com/microsoft/vcpkg.git
git clone --recurse-submodules https://github.com/BeamMP/BeamMP-Launcher.git

^ loading ■■■■ up

cmake -DCMAKE_BUILD_TYPE=Release . -B bin -DCMAKE_TOOLCHAIN_FILE="~/Downloads/vcpkg/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-linux

^ watch the toolchain path!

cmake --build bin --parallel --config Release

^ building

b-b-but it should be intuitive and completely straightforward! this is outrageous! im uninstalling linux, this is absolutely incomprehensible!!!

yeah. you have to set the correct path to your cloned vcpkg.
it’s pretty sneaky, this one, i had the same situation. frantically googling “how to setup vcpkg for compiling” and ■■■■. were you to try to blindly follow the instructions from beamMP’s github or the beamMP on linux guides:

CMake Error at /usr/share/cmake/Modules/CMakeDetermineSystem.cmake:152 (message):
  Could not find toolchain file: ~/vcpkg/scripts/buildsystems/vcpkg.cmake
Call Stack (most recent call first):
  CMakeLists.txt:3 (project)


CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

that’s because the instructions are ■■■■■■■ unclear, perhaps? @WiserTixx

you dont have to “configure” anything, except running the bootstrap. no need to fiddle and tinker with exporting any variables!!! waste of time. it’s as shrimple of a matter as cloning and compiling, that’s it. unless you’re a developer. oh well, then you should know better.

the official instructions DO need to be more precise, though. it’s a miracle that we even have a linux userbase for a game that runs only on X11. but that’s a story for another time…
