/usr/bin/ld final link failed bad value

[sfederici]

Hi Michal, I'm trying to install luacrypto by using luarocks in Ubuntu 16.10. I first installed luarocks then I tried running

luarocks install lapis

but I got an error message saying that the luacrypto package couldn't be installed because it couldn't find the evp.h file of openssl.

So, as suggested in the error message, I tried with

luarocks install luacrypto OPENSSL_DIR=/usr/local OPENSSL_LIBDIR=/usr/local/ssl/ lib OPENSSL_INCDIR=/usr/local/ssl/ include

This time I got the following output and error message:

Installing https://rocks.moonscript.org/luacrypto-0.3.2-2.src.rock...

/usr/bin/ld final link failed bad value
collect2: error: ld returned 1 exit status

I understand that I should recompile luacrypto with the -fPIC flag? Is that correct? If this is the solution, as I'm not expert about libraries and compilation, could you please let me know how I can recompile luacrypto (that I already downloaded) with this flag?

Note: I'm using openssl 1.0.2k.

Thanks in advance
