Wrong check for libevent

[RoyBellingan]

I'm getting the error
...
checking for libevent >= 1.0... no
configure: error: Please install libevent

The code used to check the libevent version is https://gist.github.com/RoyBellingan/42d1cd5a974e64ce3367
(of course the stdio and the printf are mine, I've also hardcoded the min requested version)
This is around line 18070 in configure (another check is around 19888)
The first check is failed (and secondo seems to pass or is not executed) but the version is 2.0.21-stable

I had the same problem (same output as you). From looking at my config.log, it seems the problem actually wasn't libevent, it was that double-conversion library could not be found (forgot to add it it LDFLAGS and LD_LIBRARY_PATH). Not sure if you have the same problem but hopefully this helps.

I'm trying to get proxygen to build on Centos 7. Proxygen clones and builds fbthrift. I will send in the deps scripts if I can get them working. I too am having a failure in the check for libevent in ./configure. Looking into the config.log it creates a conftest.c, compiles and runs the executable. The executable fails with the error:
"./conftest: error while loading shared libraries: libfolly.so.18: cannot open shared object file: No such file or directory"

If I manually add the folly/.libs directory to the LD_LIBRARY_PATH:
export LD_LIBRARY_PATH="pwd/folly/folly/.libs/:$LD_LIBRARY_PATH" configure finishes successfully. This is the cause of my particular "libevent" version failure.
