I am trying to compile nginx on Ubuntu machine with GCC. My Glibc version is 2.31.
m@feynman:~/Junk/nginx-1.9.9
$ /lib/x86_64-linux-gnu/libc.so.6 --version
GNU C Library (Ubuntu GLIBC 2.31-0ubuntu9.2) stable release version 2.31.
I have downloaded a bunch of different versions from https://nginx.org/download/ and tried with them and fails every time.
./configure --with-threads --with-http_ssl_module --with-cc-opt="-Wno-error"
make
./configure generates following file in objs/Makefile:
CC = cc
CFLAGS = -pipe -O -W -Wall -Wpointer-arith -Wno-unused -Werror -g -Wno-error
CPP = cc -E
LINK = $(CC)
...
This gives me this error below.

I tried installing SSL lib and others like that and thought it would help and nothing worked.
sudo apt install libpcre3-dev libssl-dev
In case anyone was looking for a solution to the problem itself:
The field current_salt is no longer the name of the field where the result is stored and needs to be updated.
Instead, the field name is output, as defined in /usr/include/crypt.h on such a system:
/* Memory area used by crypt_r. */
struct crypt_data
{
/* crypt_r writes the hashed password to this field of its 'data'
argument. crypt_rn and crypt_ra do the same, treating the
untyped data area they are supplied with as this struct. */
char output[CRYPT_OUTPUT_SIZE];
