I am trying to compile a new package that is based on OpenWRT (it is some kind of a modified OpenWRT). During the ./configure proccess I am getting a fail due to OpenSSL that is missing but when I checked it is already insatlled.

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = "en_US.UTF-8",
    LC_ALL = (unset),
    LC_COLLATE = "C",

    LANG = "en_US.UTF-8"
    are supported and installed on your system.

Build dependency: Please install the openssl library (with development headers)

Prerequisite check failed. Use FORCE=1 to override.
make: *** [staging_dir/host/.prereq-build] Error 1

When I run yum install openssl or yum install openssl-devel I am getting

Package openssl-1.0.1e-57.el6.x86_64 already installed and latest version

I already looked at similar issues such - OpenSSL missing during ./configure. How to fix? and OpenSSL not found during ./configure but they didn't help in my case.

Not sure if it is related but maybe those locale warning I am getting at the beginning are related?

My OS is CentOS 6.

Thanks!

Checking 'libssl'... failed might be the reason. Is there a package that provides libssl? Perhaps yum install libssl? I know Ubuntu has a libssl-dev package. – Nathan.Eilisha Shiraini – 2017-07-12T11:45:49.387

@NathanShiraini AFAIK libssl-dev is openssl-devel in CentOS – A. Sarid – 2017-07-12T11:46:52.203

It appears you have openSSL installed but you don't have it installed with the developer handles, per the error message, "Please install the openssl library (with development headers)" – Ramhound – 2017-07-12T16:41:46.313

Of course 1.0.1e isn't the current version either. – Ramhound – 2017-07-12T16:42:16.780

@Ramhound isn't openssl-devel the "development headers"? – A. Sarid – 2017-07-12T19:19:12.807

Have you tried to remove openssl then install it? – Ramhound – 2017-07-12T19:37:51.323

You may need to override the default location of the header files. You should start (and end?) by looking at documentation for the package you are trying to build. Usually, this means setting an environment variable fore ./configure or by adding an argument to the program. – lungj – 2017-07-12T20:19:05.960

For anyone who might run into the same problem.
As @lungj pointed out in the comments, it seems that the issue was due to environment variables that were wrongly configured.

Unsetting the following solved the problem:

unset LD_LIBRARY_PATH
unset LDFLAGS
unset CFLAGS

I didn't had to install/change anything else.
