Build Failed Ubuntu 14.04

[nburn42]

I am running ubuntu 14.04.
I have installed realpath, and checked that I have all dependencies that are listed.
I also ran bazel clean then rerun with the same results.

Thanks

Can you try adding -lm to the relevant linkopts?

[nburn42]

Thanks that helped some.

This command now works.

lab$ bazel run :random_agent --define headless=false -- \
               --length=10000 --width=640 --height=480

But this command results in an error.

lab$ bazel run :game -- --level_script tests/demo_map

What I did.
I added -lm to bspc as below, which resulted in the following error.

I tried both

linkopts = ["-pthread", "-lm"],

and

linkopts = ["-lm", "-pthread"],

with bazel cleans.

Thanks

Interesting. Can you remove the linker script from the DSO build rule? We were trying to isolate the DSO as much as possible, since we don't have a lot of control over all the external names in it, but it may be interfering here. Alternatively, try adding -lm also to the DSO build rule.

[nburn42]

Sorry about the delay.

I found that linking the math library into :game fixed my second issue.
It fixed the problems on both ubuntu 16.04 and 14.04.

All the bazel commands on the instructions now work.
I submitted a pull request with the change.

Thanks for the help.

[tkoeppe]

We will make a change similar to the one proposed in #12 in the future, which should address this. Thanks for raising!
