===TLDR added at end of this experience===Go to post #10 for the final result of the particular use case: CoreUtils
Go to post #14 for the questions that I formed after this whole experience.
===Start of original post======Goal===Cross compile and build CoreUtils on an x86 for use on my Amiga X1000 OS 4 FE U2.
===Some Info===I will not post all commands in here, some obvious ones like copying directories I will ommit. The reason for posting all of this information is purely because of my own experiences: I hate it when searching for information and coming across a potentially great thread that does not contain enough information.
I also create this quasi-step-by-step guide because someone will probably go: NO! Don't do it like that! For example, I may be using an out-of-date guide or using a git-hub location that is way out of date, or, just doing something plain-wrong!
Lines that begin with "PRESUMPTION:" document my thought process and general questions.

Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal
===Source Code for CoreUtils===https://github.com/adtools/coreutils===Guide(s) I am using for my goal===I am really only using README.os4 / README and browsing the configure file to glean information.
===Start Doing Things===I am going to create a CHROOT using Xenial 32-bit because we want to use 32-lib libraries and it comes with GCC version 5.X***; all the packages mentioned as requisites for compiling the cross tool chain match up with Xenial. I do not want to mess around with multi-arch etc and having a CHROOT seems a lot cleaner. It has been a long time since I did this, so there maybe easier or better methods.
*** - I mention this because I need to compile the cross-compiler toolchain, and the prerequisites mentions a need for GCC 5.X 32-bit.
===CHROOT a Xenial 32-bit===I will create a directory: /var/2xenial32 which will be the root for the 32-bit Xenial.
I will use debootstrap to create a minimal image:
debootstrap --variant=buildd --arch i386 xenial /var/chroot/2xenial32/ http://archive.ubuntu.com/ubuntu/
Copy the apt/sources and rename focal to xenial so that I can access the right repos for packages.
===Okay, now I need to get a cross compiler before building CoreUtils===I will use:
https://github.com/adtools/amigaos-cross-toolchainAnd the guide for that:
https://github.com/adtools/amigaos-cro ... ain/blob/master/README.md.
We will create the gcc 4.2.4 cross-compiler for OS 4 FE U2.
Let me CHROOT into the 2xenial32 and start building the cross toolchain. Before I can even start, let's get all the prerequisites in the README.md file. This is essentially running apt-get install for each of these packages. It also includes running install for a few other packages that are not mentioned in the README file that must have been left out by mistake; I needed to also install subversion and flex.
Also, during step 2 of the README.md:
./toolchain-ppc --prefix=/opt/ppc-amigaos build
the script (toolchain-ppc) will hang when trying to download
http://isl.gforge.inria.fr/isl-0.12.2.tar.bz2 because this file no longer exists. So, I just searched for it and hacked in a new url.
Then, I run: ./toolchain-ppc --prefix=/opt/ppc-amigaos build
and wait for a long time, since the host machine is real slow!
And, when it is finished I test the default paths etc for the compiler:
$> ./ppc-amigaos-gcc -xc -E -v -
Using built-in specs.

===Peforming a basic test of hello world===As the heading suggest, I now create a simple application printing out hello world, scp to amiga and run it to ensure that it works so far.
Since the compiler defaults to newlib I compile helloWorld both by default and by appending -mcrt=clib2.
Both binaries work.
===Get back to building CoreUtils===Since the README.os4 for CoreUtils says:
Quote:
06-08-2017 - Version 54.1
Coreutils 8.29 source used for the port
The sourcecode for Sort and Split have been replaced with the old 5.2.1-9 code.
To compile you need libwide found on http://os4depot.net and the current clib2 code from http://github.com/adtools/clib2
I should probably get libwide and the "current" clib2 from the github. So, let's do that.
===libwide===Just extract it into the SDK directory.
===clib2===The issue is that for the documentation readme file for building
http://github.com/adtools/clib2 says:
Quote:
In order to build the library, you need a 'C' compiler (obvious, isn't it?) and a set of header files for the networking API definitions. The networking header files go into a directory netinclude which has to sit in the same directory as the source code and the include directory you find in there. I'm not currently supplying these header files here. Drop me a line, and I'll take care of that.
So, I am not sure how to get the "netinclude".
Quote:
PRESUMPTION: let's just see if the CLIB created by the X-toolchain works.
Since the default for the X-compiler is not to use CLIB, I am assuming I need to override that and add CFLAGS=-mcrt=clib2 as well as set the --host=ppc-amigaos. The X-compiler needs to be on the path also!
Quote:
PRESUMPTION: Should I add -lwide? For now, I am not.
But, just to see what happens I try:
./configure --host=ppc-amigaos
And this generates okay, but when I try
make
I get:
make[2]: Entering directory '/home/Amiga/coreutils-master'

And, when you look at that line you can see:

/* Initialize time conversion information. */
# if @GNULIB_TZSET@
# if @REPLACE_TZSET@

# endif
_GL_CXXALIAS_SYS (tzset, void, (void));
# endif

# endif
#endif
So, as I already saw in the readme, we should be building with clib2!
Okay, so now I try (after cleaning out directory completely. Essentially, deleting it and copying a new one):
./configure --host=ppc-amigaos CFLAGS=-mcrt=clib2
in this case, we get a Makefile again, but:
make
results in:

So, function 'gethostname' was already:

But in the core-utils directory that I am trying to build:
_GL_FUNCDECL_SYS (gethostname, int, (char *name, size_t len)
_GL_ARG_NONNULL ((1)));
already exists.
Quote:
PRESUMPTION: Sure, I can hack to get passed this, but clearly I am not doing something correct in the initial configuration.
So, I am just wondering if someone can help point me in the right direction.
Thanks all.
