The Lerna script cannot find boost when building C++ modules

When I built on MacOS (having installed Boost using brew) everything is fine.

When I followed the directions on Ubuntu, the lerna build script fails whenever a C++ module needs Boost. I have Boost installed with apt install libboost-dev (so it's in /usr/include).

Here's a sample of just one of the many similar errors: @jpmorganchase/perspective: In file included from /home/dj/usr/src/perspective-clone/packages/perspective/src/cpp/build_filter.cpp:11: @jpmorganchase/perspective: In file included from /home/dj/usr/src/perspective-clone/packages/perspective/src/include/perspective/build_filter.h:12: @jpmorganchase/perspective: In file included from /home/dj/usr/src/perspective-clone/packages/perspective/src/include/perspective/filter.h:12: @jpmorganchase/perspective: /home/dj/usr/src/perspective-clone/packages/perspective/src/include/perspective/base.h:29:10: fatal error: 'boost/unordered_map.hpp' file not found @jpmorganchase/perspective: #include \n ^~~~~~~~~~~~~~~~~~~~~~~~~

I had the same issue on ubuntu (WSL) and had to copy the boost headers to /src/boost_includes (as expected by CMake - see CMakeLists.txt in perspective package)
Changing the include to point to /usr/include would cause clash with emscripten specific includes.

Hmmm ok I see that in the CMakeLists.txt. I'm not sure people are going to want to create a root level directory called /src/boost_includes and link it to /usr/include (or wherever their boost installation is). Also, some people might not even have sudo ability to do that. Am I misunderstanding what you did to solve this?

thx

I ran into the same issue few weeks ago when attempting to build on Ubuntu 16.04.

I was able to resolve the issue by copying boost folder, but without modifying cmake files.

I used the following command: cp -R /usr/include/boost <PERSPECTIVE_ROOT>/src/include/perspective and the project build successfully.

You might be able to save hard drive space by creating symbolic link without copying full folder, but I haven't tried that approach.

If you don't have sudo permissions, you can try building perspective on another machine, and copying the generated files on your development machine.

Hey that worked -- thank you!

The issue is that CMake generates "-i/usr/include" when resolving boost, and on Ubuntu+boost installed via apt, this directory also contains system headers, clobbering the modified ones which are included in the Emscripten SDK.

Current workaround was lifted from this suggestion.

My current thinking is that the best solution to this is to build a custom docker image containing emsdk and the boost headers in a segregated location, as we mostly already do on our travis builds. This isn't ideal (dockerd needs elevated access) but at least it is portable.

cp -r /usr/include/boost ./packages/perspective/src/include/ got it going for me. No way to script this into the build process?

There is now a PSP_DOCKER environment variable which will run the Emscripten portion of the build with a Docker packaged version of Emscripten:

PSP_DOCKER=1 npm run build
