Cannot build on OSX 10.14.2

[giwiro]

The main issue is that currently I cannot compile pg_hashids, with this versions:

• OSX: 10.14.2
• MacOS SDK: MacOSX10.14.sdk
• PostgreSQL: 10.1

The log is the following:

gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -mmacosx-version-min=10.8 -arch i386 -arch x86_64 -O2  -I. -I./ -I/Library/PostgreSQL/10/include/postgresql/server -I/Library/PostgreSQL/10/include/postgresql/internal -I/opt/local/Current/include -I/opt/local/20151229/include/libxml2  -I/opt/local/Current/include/libxml2 -I/opt/local/Current/include  -c -o pg_hashids.o pg_hashids.c

#include <stdio.h>
         ^~~~~~~~~

make: *** [pg_hashids.o] Error 1

Then what I did was install the tools provided by xcode with this:

xcode-select --install

Then I installed macOS SDK Headers with this:

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Inside my /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer folder what I got is this:

What I tried is to create a symlink to MacOSX.sdk through MacOSX10.8.sdk so the makefile could find it. But it gives a new error

What's the result of pg_config --pgxs?

[giwiro]

This is what i got after pg_config --pgxs:

/Library/PostgreSQL/10/lib/postgresql/pgxs/src/makefiles/pgxs.mk

And this is the content of the pgxs.mk file:

# PGXS: PostgreSQL extensions makefile

# src/makefiles/pgxs.mk

# This file contains generic rules to build many kinds of simple
# extension modules.  You only need to set a few variables and include
# this file, the rest will be done here.
#
# Use the following layout for your Makefile:
#
#   [variable assignments, see below]
#
#   PG_CONFIG = pg_config
#   PGXS := $(shell $(PG_CONFIG) --pgxs)
#   include $(PGXS)
#
#   [custom rules, rarely necessary]
#
# Set one of these three variables to specify what is built:
#
#   MODULES -- list of shared-library objects to be built from source files
#     with same stem (do not include library suffixes in this list)
#   MODULE_big -- a shared library to build from multiple source files
#     (list object files in OBJS)
#   PROGRAM -- an executable program to build (list object files in OBJS)
#
# The following variables can also be set:
#
#   EXTENSION -- name of extension (there must be a $EXTENSION.control file)
#   MODULEDIR -- subdirectory of $PREFIX/share into which DATA and DOCS files
#     should be installed (if not set, default is "extension" if EXTENSION
#     is set, or "contrib" if not)
#   DATA -- random files to install into $PREFIX/share/$MODULEDIR
#   DATA_built -- random files to install into $PREFIX/share/$MODULEDIR,
#     which need to be built first
#   DATA_TSEARCH -- random files to install into $PREFIX/share/tsearch_data
#   DOCS -- random files to install under $PREFIX/doc/$MODULEDIR
#   SCRIPTS -- script files (not binaries) to install into $PREFIX/bin
#   SCRIPTS_built -- script files (not binaries) to install into $PREFIX/bin,
#     which need to be built first
#   REGRESS -- list of regression test cases (without suffix)
#   REGRESS_OPTS -- additional switches to pass to pg_regress
#   NO_INSTALLCHECK -- don't define an installcheck target, useful e.g. if
#     tests require special configuration, or don't use pg_regress
#   EXTRA_CLEAN -- extra files to remove in 'make clean'
#   PG_CPPFLAGS -- will be added to CPPFLAGS
#   PG_LIBS -- will be added to PROGRAM link line
#   SHLIB_LINK -- will be added to MODULE_big link line
#   PG_CONFIG -- path to pg_config program for the PostgreSQL installation
#     to build against (typically just "pg_config" to use the first one in
#     your PATH)
#
# Better look at some of the existing uses for examples...

Try xcode-select --install and/or reset sudo xcode-select --reset. You don't need to install the macOS_SDK_headers_for_macOS_10.14.pkg

[giwiro]

I tried both command with no success at all, the official OSX SDK version has changed and now it's 10.14 instead 10.8

[NightMachinery]

ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk' this solved my problem, though I was using cling and not iCyberon.

Thanks, it is work for me
