/usr/bin/ld: cannot find -lclang

You need to install libclang

timuckun commented 8 years ago

I installed that and the rest of the rest of the libs but maybe I am still missing something.

make
crystal build src/main.cr

What's your OS? How did you install Crystal?

timuckun commented 8 years ago

I could not install it on a mac so I am trying it on ubuntu 16-04 (virtualbox). I installed crystal using the instructions. I added the repository and then apt-get install crystal.

Sorry, I don't know what else to do to help you

@timuckun I solved this problem:

$ sudo apt-get install -y libclang-dev
$ ldconfig -p | grep libclang
#     libclang-3.8.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libclang-3.8.so.1
#     libclang-3.8.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libclang-3.8.so
#     libclang-3.5.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libclang-3.5.so.1
#     libclang-3.5.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libclang-3.5.so     
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libclang-3.8.so.1 /usr/lib/x86_64-linux-gnu/libclang.so
