I've been trying to install the S3 tools and am encountering errors when running 'make'
I have installed aws4c and tested it, it works fine. Running Scientific Linux 7.4.

My current directory looks like this
ior-tests
--aws4c-lanl
--ior-master

openmpi, libcurl, libxml, libcrypto and libssl are all installed in /lib64/
I've ran the configure command as follows

./configure --with-S3 --with-aws4c=/root/ior_tests/aws4c-lanl/ LDFLAGS="-L/lib64/" CPPFLAGS=-I/usr/include/libxml2

Which does not throw any errors, however when I run make I get the following output:

Making all in src make[1]: Entering directory `/root/ior_tests/ior-master/src' make all-am make[2]: Entering directory `/root/ior_tests/ior-master/src' mpicc -std=gnu99 -g -O2 -L/root/ior_tests/aws4c-lanl/ -L/lib64/ -o ior ior-ior.o ior-utilities.o ior-parse_options.o ior-aiori.o ior-aiori-MPIIO.o ior-aiori-POSIX.o ior-aiori-S3.o -lcurl -lxml2 -laws4c -laws4c_extra -lm /usr/bin/ld: /root/ior_tests/aws4c-lanl//libaws4c.a(aws4c.o): undefined reference to symbol 'BIO_free_all@@libcrypto.so.10' /usr/lib64/libcrypto.so.10: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [ior] Error 1 make[2]: Leaving directory `/root/ior_tests/ior-master/src' make[1]: *** [all] Error 2 make[1]: Leaving directory `/root/ior_tests/ior-master/src' make: *** [all-recursive] Error 1

The lines with the erros seem to be these two:

/usr/bin/ld: /root/ior_tests/aws4c-lanl//libaws4c.a(aws4c.o): undefined reference to symbol 'BIO_free_all@@libcrypto.so.10'
/usr/lib64/libcrypto.so.10: error adding symbols: DSO missing from command line

I've been stuck on those for a couple days now and any help would be appreciated, I'm also a recent graduate so still new to this.
