trouble compiling on centos6 (libsodium-16 & libsodium-16-devel installed) #46

Closed mynameisajay closed 4 years ago

mynameisajay commented 4 years ago

Hi, I am trying to compile this (release 0.17.2 and 0.16.0 tried) on centos 6 with OTP 22. The sodium.h is installed in /usr/include and points to files in /usr/include/sodium (both of which I checked to make sure).

`Erlang/OTP 22 [erts-10.6.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]

Eshell V10.6.3 (abort with ^G) 1> `

I keep getting this error:

I don't know what I could be doing wrong.

Also, just to make sure, I wrote a test file in c that includes and links to it and everything works.

This is was my fault. I had an older version of libsodium compiled from src in /usr/local/include which trumps /usr/include. Hence the issues. 

gcc -xc -E -v -

helped me. closing issue.
