I specified 
PKG_CONFIG_PATH=/Users/bryan/Software-Swift5/chronyd/Crypt/opt/lib/pkgconfig 
and that has solved the problem for nettle.

I am now trying to get gnutls built as a static library without it picking up 
anything from my /usr/local directory. Unfortunately, it is not good practice 
on macOS to ask users to install these libraries etc with a package manager - 
Applications are supposed to be self contained.

It would be good if the config.log had a complaint about not being able to 
build the complete command.

Maybe also add the following hint to ./configure -h (This is what is present in 
the gnutls configure script)

Some influential environment variables:
  PKG_CONFIG  path to pkg-config utility
  PKG_CONFIG_PATH
  directories to add to pkg-config's search path
  PKG_CONFIG_LIBDIR
  path overriding pkg-config's built-in search path

This command is missing -lnettle. That's probably because pkg-config
is missing or the nettle pc file was not found.

I should improve the configure script and documentation.

[chrony-dev] Problems building with nettle-3.5

2020-03-09 Thread Bryan Christianson 
I am trying to compile chrony-git with nettle-3.5 built as static library.

As far as I can tell nettle has built OK and is installed where I expect it to 
be.

In config.log I am seeing:

docheck.c:
#include "config.h"
#include 
#include 
int main(int argc, char **argv) {
return nettle_hashes[0]->context_size;
return 0; }
gcc -mmacosx-version-min=10.10 -Wmissing-prototypes -Wall 
-I/Users/bryan/Software-Swift5/chronyd/Crypt/opt/include -o docheck docheck.c 
-L/Users/bryan/Software-Swift5/chronyd/Crypt/opt/lib
Undefined symbols for architecture x86_64:
  "_nettle_get_hashes", referenced from:
  _main in docheck-5b59e0.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)


Any help appreciated.
