Can you try pull request 2376 to see if that fixes this build error?

[retif]

Yes, your pull request helps. AirSim plugin is built!

[retif]

Also i was trying to build AirSim Unity Wrapper and it failed to find boost headers and libraries.
AirSim/Unity/AirLibWrapper/CMakeLists.txt does not manage boost library.
Error of finding headers i managed to fix by adding

FIND_PACKAGE(Boost REQUIRED)

MESSAGE("  Boost_LIBRARIES: ${Boost_LIBRARIES}") 
MESSAGE("  Boost_LIBRARY_DIRS: ${Boost_LIBRARY_DIRS}") 
MESSAGE("  Boost_FILESYSTEM_LIBRARY: ${boost_filesystem_DIR}") 

INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES(${Boost_LIBRARIES})

But it still can not link with boost

Oleksandr Kuksenko (@retif) You were pretty close :) I managed to setup builds for Ubuntu 16.04, 18.04, Windows & OSX on Travis (#2356) Took some time and a few hacks 😅 but was able to get builds for Unreal and Unity working on all of them.
Though Travis needs to enabled for AirSim again since it's not triggering right now

I have 2 other PRs for fixing these build issues, first of which is #2333, which fixes some slightly subtle problems in setup.sh & build.sh
The other is #2328 which fixes problems for Unity build, this one has the CMake additions as well
Sorry for the spreading of fixes across different PRs, things are separate from each other so as to reduce the scope of individual PRs and for easier review and understanding. Merging them will cause conflicts in some places but that can be easily fixed one after the other.

Getting builds to pass will need all 3 PRs, but this will reduce the likelihood of things breaking in the future.
Finally, Travis build of the end result after merging everything - https://travis-ci.com/rajat2004/AirSim/builds/145052865

Hope this helps!

Awesome job ! I'm struggling with a lambda related warning, which I think you are fixing in #2328 ! I'm going to give it an other try with your patch !

[retif]

I managed to build Unity AirsimWrapper in MacOS

in CMakeLists.txt i was added

FIND_PACKAGE(Boost REQUIRED)
MESSAGE("Boost information:") 
MESSAGE("  Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}") 
MESSAGE("  Boost_LIBRARIES: ${Boost_LIBRARIES}") 
MESSAGE("  Boost_LIBRARY_DIRS: ${Boost_LIBRARY_DIRS}") 
MESSAGE("  Boost_FILESYSTEM_LIBRARY: ${boost_filesystem_DIR}") 

INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES("/usr/local/lib")

Also AirSim/Unity/build.sh contains small error:

if [ "$(uname)" == "Darwin" ]; then
	cp AirsimWrapper.bundle ../UnityDemo/Assets/Plugins;
else
	cp libAirsimWrapper.so ../UnityDemo/Assets/Plugins;
fi

AirsimWrapper.bundle is a directory so -r should be added to cp

I'm struggling with a lambda related warning, which I think you are fixing in #2328 ! I'm going to give it an other try with your patch !

Is the warning coming when building for Unreal? The one which I've fixed in the PR is in Unity, but it's one of about 350 warnings, so it's not of any importance. Still need to figure out the warnings flags.

FIND_PACKAGE(Boost REQUIRED)
MESSAGE("Boost information:") 
MESSAGE("  Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}") 
MESSAGE("  Boost_LIBRARIES: ${Boost_LIBRARIES}") 
MESSAGE("  Boost_LIBRARY_DIRS: ${Boost_LIBRARY_DIRS}") 
MESSAGE("  Boost_FILESYSTEM_LIBRARY: ${boost_filesystem_DIR}") 

INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES("/usr/local/lib")

If possible, could you try building with the CMake changes in the PR? I don't have a Mac to test, but the build is passing so it should work. I'm not sure about hard-coding the library location, and the manpage also discourages it

Also AirSim/Unity/build.sh contains small error:

if [ "$(uname)" == "Darwin" ]; then
	cp AirsimWrapper.bundle ../UnityDemo/Assets/Plugins;
else
	cp libAirsimWrapper.so ../UnityDemo/Assets/Plugins;
fi

AirsimWrapper.bundle is a directory so -r should be added to cp

Yes, fixed that in the Travis PR. It was also mentioned in another issue or PR of AirSim

Yes exactly. I tried building from master and it worked pretty well.

Sure I'm going to fetch your branch and give it a try

Edit: Ok the llvm 5.0 brew recipe seems to still be broken. I'm going to use the install script you provided on travis and try again

Well, wasn't aware of that, used on binaries on Travis since brew install llvm took more than 2 hrs which is the time-limit on Travis. Maybe could add the usage of binaries rather than brew install in setup.sh? Thought for another day

Definitely ! there were also a couple of things that prevented me to run setup and build successfully ($CMAKE wasnt set in this path etc)...

I have a patch ready that seems to fix the build, but it also contains your fixes.
Should I wait until your land your patches, or would you rather include the diff i can send you ? :)

[rajat2004]

Diff would be great! I could add any additional commits required in the currently open PRs
Regarding the problem with CMake, that is included in #2333, the problem was that the part of code which finds the CMake binary was inside the else() function for Linux which caused the variable to not being set

While reading your PR i cant see how it can fix the problem for me, because ${Boost_LIBRARIES} variable is empty after FIND_PACKAGE(Boost REQUIRED) as you can see in my previous error log:

Boost information:
  Boost_INCLUDE_DIRS: /usr/local/include
  Boost_LIBRARIES:
  Boost_LIBRARY_DIRS:
  Boost_FILESYSTEM_LIBRARY:

at my last comment i said that LINK_DIRECTORIES("/usr/local/lib") fixed last problems with build, normally there should be $Boost_LIBRARY_DIRS, but this variable is also empty as you can see.
Need to figure out why those variables stay empty.

[rajat2004]

Not sure, maybe you need to specify the components such as filesystem?
This is the output I'm getting on Travis -

CMake Warning at /usr/local/lib/cmake/boost_filesystem-1.71.0/libboost_filesystem-variant-shared.cmake:59 (message):

The warning regarding the multithreaded library is something specific to Boost 1.71 which I'll test and commit the fix

there you go :D

Oh btw there's a lot I couldn't figure out with required variable names (C? CXX?) and there's a lot of hacky code duplication because we're not sourcing variables that we want to reuse across scripts.

All I know is that it is building on my machine.

I don't have enough build systems knowledge to know which settings make cmake happy and which don't, but I can refine it if need be ^^'
