[CMake] Could NOT find Boost (missing: Boost_INCLUDE_DIR system date_time regex) | Together C & C++ | Page 1

Hello everybody!

So I'm totally new to this CMake and such. I got stuck half way in trying to install mailio lib. I have installed boost and I've watched youtube videos about CMake and even checked out their website regarding find_package().

This is the line where the program terminates:
"find_package(Boost REQUIRED COMPONENTS system date_time regex)"

I still could'nt resolve the problem. I kindly ask for thy help
Sincerely, Dani

I've tried specifying the full path as well instead of just the name "Boost"

main seal Jan 20, 2024, 12:02 PM

#

Am I in the wrong section or does no one code with external libraries here?

nimble blaze Jan 20, 2024, 12:07 PM

#

Need more information

#

What is the full cmake error?

#

Please also send your CMakeLists.txt

main seal Jan 20, 2024, 12:08 PM

#

Thank you for replying. That is the part that gets terminated. The cmakelist is the original from mailio but yes I can send it. Gimme a sec

nimble blaze Jan 20, 2024, 12:09 PM

#

What do you mean specifically by terminated?

main seal Jan 20, 2024, 12:10 PM

#

Like I press generate and then it starts with the lines specifying c++ version and such. Then when it reaches boost it terminates cuz it can’t find it

#

📎 CMakeLists.txt

#

Line: 64

#

and where is your boost installed?

main seal Jan 20, 2024, 12:12 PM

#

in c:/local

#

I tried specifying full path as well

#

w/o result

pallid shadow Jan 20, 2024, 12:13 PM

#

and you have the static libs you're asking for?

#

system date_time regex

main seal Jan 20, 2024, 12:13 PM

#

This?

#

C:\local\boost_1_84_0\libs\date_time

pallid shadow Jan 20, 2024, 12:15 PM

#

did you build boost?

#

some boost libraries are header only and don't require building, but boost.system, boost.date_time, boost.regex need to be built

#

and since the CMakeLists.txt does set(Boost_USE_STATIC_LIBS ON) find_package looks for static libs

main seal Jan 20, 2024, 12:16 PM

#

i first tried the zip and then the binary installer

#

so it should be build this time after using binary installer right?

pallid shadow Jan 20, 2024, 12:16 PM

#

I dunno what installer that is or what it installs

#

do you have .lib files in there somewhere?

main seal Jan 20, 2024, 12:16 PM

#

the 3 pkgs you mentioned are in seperate dl areas?

#

i dont seem to have lib files no

#

Is this the regex?
C:\local\boost_1_84_0\boost\regex

pallid shadow Jan 20, 2024, 12:19 PM

#

that's probably where the headers and/or sources for regex are

main seal Jan 20, 2024, 12:19 PM

#

and this should be the system

#

pallid shadow Jan 20, 2024, 12:19 PM

#

yeah, these are only header files, though

#

cmake is looking for compiled libraries

main seal Jan 20, 2024, 12:20 PM

#

i feel so lost around these other areas. i just wanted to code. this feels harder than to learn the language

pallid shadow Jan 20, 2024, 12:20 PM

#

what compiler/toolchain are you using

#

VS / MSVC? Some MinGW/msys2 GCC?

main seal Jan 20, 2024, 12:20 PM

#

tried multiple, now i had to do vs

#

vs only not code

#

I believe its gnu c

pallid shadow Jan 20, 2024, 12:21 PM

#

in visual studio? thonk

#

it's possible but normally you'd use microsoft's compiler in VS

main seal Jan 20, 2024, 12:21 PM

#

atleast it was in code::block

pallid shadow Jan 20, 2024, 12:23 PM

#

so, you have a few choices

#

you can read through the boost documentation to figure out how to build it, as static libraries, for windows/your compiler

#

or you can use a package manager to install boost

main seal Jan 20, 2024, 12:24 PM

#

pallid shadow Jan 20, 2024, 12:24 PM

#

👍

main seal Jan 20, 2024, 12:24 PM

#

sorry you wanted the whole msg

pallid shadow Jan 20, 2024, 12:24 PM

#

I can guess what it will say

main seal Jan 20, 2024, 12:24 PM

#

#

package manager is cmake or vcpkg right?

pallid shadow Jan 20, 2024, 12:25 PM

#

vcpkg yeah

#

cmake is a build system (kind of)

main seal Jan 20, 2024, 12:25 PM

#

oh I see

#

There was a section using that too

#

Ok I will try using the vcpkg and google even more. Is it hard for everyone starting with external libraries? I thought the hardest part was learning programming logic...

pallid shadow Jan 20, 2024, 12:28 PM

#

in C++, yes it can be hard :v

nimble blaze Jan 20, 2024, 12:29 PM

#

That is the easiest part

pallid shadow Jan 20, 2024, 12:29 PM

#

you could also try one of these installers: https://sourceforge.net/projects/boost/files/boost-binaries/1.84.0/

#

14.3 is the VC++ version you have

main seal Jan 20, 2024, 12:30 PM

#

nimble blaze That is the easiest part

lol then i might be fkd xD

main seal Jan 20, 2024, 12:31 PM

#

pallid shadow 14.3 is the VC++ version you have

im so greatful of your help. much appreciated fam!
i will try these abit later and hopefully i can start coding.

@main seal Has your question been resolved? If so, type !solved :)

main seal Jan 20, 2024, 12:52 PM

#

@pallid shadow i fkng love u

#

i used the vcpkg and then on sqlite i saw they used integrate install

#

that was so fkn easy that i want to trash myself...

#

!solved
