Error building libhttp

[bhakta0007]

Hello, I am encountering an error when trying to build. This appears to be a case of warning treated as error. Do the build instructions still hold good? (I tried make build and it gave me an error)

Issue 1: Build issue on ubuntu

$ uname -a Linux ubuntu 4.13.0-16-generic #19-Ubuntu SMP Wed Oct 11 18:35:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

$ make cc -c -Wall -Wextra -Wstrict-prototypes -Wshadow -Wpointer-arith -Wformat-security -Winit-self -Wcast-qual -Wcast-align -Wwrite-strings -Wnested-externs -Wredundant-decls -Werror -O3 -funsigned-char -Iinclude/ -DUSE_STACK_SIZE=102400 -oobj/httplib_error_string.o src/httplib_error_string.c src/httplib_error_string.c: In function ‘httplib_error_string’: src/httplib_error_string.c:170:2: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result] strerror_r( error_code, buf, buf_len ); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Makefile:148: recipe for target 'obj/httplib_error_string.o' failed make: *** [obj/httplib_error_string.o] Error 1

Issue-2: on MAC the build failed with a different error:

On removing Werror from Makefile, the Ubuntu compiles, however I am curious to know why there are warnings in the code?

update: I moved over to civetweb project and the same example builds there.

dir example and dir test don‘t adapt the project.should modify parameter and struct .
