Build fails on Ubuntu [Cereal Error] about flashlight

[jacobkahn]

@shaheenkdr — before I continue, I'll be sending a change shortly which automatically downloads and installs cereal headers for you when you build flashlight, so if you're still having trouble, that change should be in pretty soon.

The process for building and installing cereal headers is as follows:

1. Clone cereal, and switch to the develop branch:

git clone https://github.com/USCiLab/cereal.git && cd cereal
git checkout develop

2. Build and install the headers:

mkdir -p build && cd build
cmake .. -DJUST_INSTALL_CEREAL=ON
make -j4

3. Actually move the headers to the install directory:

sudo make install -j4

When you build flashlight, it should properly find those headers.

@shaheenkdr — have you installed cereal headers? See #9 and the build requirements.

@jacobkahn Thanks for the quick response, been struggling here for quite few days as I come from a non c/cpp environment. I read the issue #9 prior to opening this issue.

Quoting from Cereal's install directory,

" cereal can be directly included in your project or installed anywhere you can access header files. Grab the latest version from Github or use the download links above, then drop the cereal folder from the include directory (cereal_base_dir/include/cereal) somewhere your project can find. There’s nothing to build or make - cereal is header only. "

When you say have you installed cereal headers? , Did you intend to say have I copied the headers to where the project can find ? If that's what you meant, I tried downloading the library, the develop branch and tried moving it to /home/flashlight/flashlight/common/ , Let me know if I have to do anything contrary to that?

@jacobkahn Thanks a ton, that resolved the issue 👍 , however, build now produces another set of issues, I probably should close this issue and open another
