Downloading Boost ASIO issue

[grizzled marsh]

I have been trying to download boost asio, but I cannot install b2. When I try to run ./b2 install --prefix=PREFIX, I got the following error.

error: Name clash for '<pC:\Boost\boost_1_82_0\stage\lib>libboost_filesystem-vc143-mt-gd-1_82.lib'
error:
error: Tried to build the target twice, with property sets having
error: these incompatible properties:
error:
error:     -  <address-model>32
error:     -  <address-model>64
error:
error: Please make sure to have consistent requirements for these
error: properties everywhere in your project, especially for install
error: targets.

I also tried to run b2 with following solution https://stackoverflow.com/questions/74901242/installing-boost-1-81-0-failing , but it didn't solve the issue neither.

asio is header only, you shouldn’t need to build anything

[grizzled marsh]

so how can I add that to my project? I am using Cmakelist.txt to build

I tried the following

cmake_minimum_required (VERSION 3.8)
cmake_policy(SET CMP0079 NEW)

# Enable Hot Reload for MSVC compilers if supported.
if (POLICY CMP0141)
  cmake_policy(SET CMP0141 NEW)
  set(CMAKE_MSVC_DEBUG_INFORMATION_FORMAT "$<IF:$<AND:$<C_COMPILER_ID:MSVC>,$<CXX_COMPILER_ID:MSVC>>,$<$<CONFIG:Debug,RelWithDebInfo>:EditAndContinue>,$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>>")
endif()

project ("HTTPProject")

# Include sub-projects.
add_subdirectory ("HTTPProject")

set(ASIO_VERSION 1.80.0)


add_library(
    Boost_lib
    SHARED
    IMPORTED
    "C:/Program Files/boost/boost_asio_1_30_2/boost/asio.hpp"
)

target_link_libraries(
    HTTPProject PRIVATE Boost_lib
)

[ember smelt]

simply download boost and set BOOST_ROOT to your path where you downloaded boost

[ember smelt]

woah

[grizzled marsh]

😄

[ember smelt]

find_package is a thing

[grizzled marsh]

so okay i will check BOOST_ROOT and do find_package let me try

[ember smelt]

set(BOOST_ROOT …)
find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})```

@ember smelt

It looks like you may have code formatting errors in your message

Note: Make sure to use back-ticks (`) and not quotes (')
Note: Make sure to specify a highlighting language, e.g. `cpp`, after the back-ticks

Markup

```cpp
int main() {}
```

Result

int main() {}

[ember smelt]

smth like that, I am writing from memory

[grizzled marsh]

so might be a dumb thing to ask but what exactly setting BOOST_ROOT as a path?

should I just add the folder path of boost to environment variables?

[ember smelt]

it’s a cmake variable

find_package(Boost) calls FindBoost.cmake

https://cmake.org/cmake/help/latest/module/FindBoost.html

BOOST_ROOT is a variable you can set if FindBoost can’t find it automatically

[grizzled marsh]

okay I tried BOOST_ROOT but it seems like i am not able to find it. CMake compiles, but still #include <asio.hpp> not found

[ember smelt]

yes

<boost/asio.hpp>

[grizzled marsh]

also i have two cmakelist files

why is that exactly?

did i make something wrong or is it normal?

[ember smelt]

you do have set HTTPProject as a subproject directory

[grizzled marsh]

this is neither found

[ember smelt]

reset cache and reload project

and see cmake messages to see that boost has indeed been found

[grizzled marsh]

i think it finds boost in the wrong folder

because i downloaded boost in to the following folder "C:\Boost\boost_1_82_0"

[ember smelt]

well if you set boost root to the download path it should work

[grizzled marsh]

I tried that with SET(BOOT_ROOT C:\Boost\boost_1_82_0 , but for some reason when I tried to call find_package it kept finding the one in the anaconda. I decided to change to visual studio environment for now. Thank you for helping
