Error ocurred when building libtorrent using cmake and ninja

[leoncwu]

Hi Arvidn, I am trying to build the library of the latest libtorrent myself. I tried to build with cmake. So, I have cmake, ninja, an boost installed. I was able to get went throught step 1 withour any error. However, when I tried to execute "ninja", the build failed with the following error:

Do you happen to know what caused this?

[arvidn]

clearly ninja can't find the boost headers. You probably want to look at the cmake output around find_public_dependency(Boost REQUIRED) and target_link_libraries(libtorrent-rasterbar PUBLIC Boost::headers)

Hi Arvidn, thank so much for the suggestions. I did some tests, and it seems that the build went through the two functions you mentioned and failed later. Just to show the whole picture, I have to paste the entire message dumped. I am sorry if this post looks awfully long. I am wondering if you would have more comments on how to address the issue.

I am just going to guess it's the boost version being 1.62 which is Debian Stretch old.

-- Found Boost: /usr/include (found version "1.62.0") found components: system

I am pretty sure you need to use a more modern version. You can do this by downloading it, extracting it, and point cmake to this instead.

[leoncwu]

Thank you so much for your comments. I want to double-check the Boost library and version. Which version should be good? I saw the following list of available libraries on Debian website. I bet it is reliable to go with stable versions, unless I have to use the latest one.

• stretch (oldoldstable) (libdevel): Boost C++ Libraries development files (ALL) (default version)
  1.62.0.1: amd64 arm64 armel armhf i386 mips mips64el mipsel ppc64el s390x

I don't use system deps to build boost. I do this.
