Find attached how I usually build gnustep-base and my ulib on Ubuntu
export CC="/usr/bin/clang"
export CXX="/usr/bin/clang++"
export RUNTIME_VERSION="gnustep-2.1"
export OBJCFLAGS="-fblocks"
export GNUSTEP_INSTALLATION_DOMAIN="SYSTEM"

This is on Ubuntu Focal. I have two stumbling blocks:
ANNOUNCE.2.1 says:
The submodule is available from:
https://github.com/Tessil/robin-map/archive/757de82.zip
https://github.com/Tessil/robin-map/archive/757de82.tar.gz
This will extract as robin-map-757de829927489bee55ab02147484850c687b620.
You must move the contents of that directory into third_party/robin_map in the
libobjc2 tree.
However, when I follow the instructions and say "cmake .." from the Build
directory, I get this warning:
CMake Warning at CMakeLists.txt:118 (find_package):
By not providing "Findtsl-robin-map.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"tsl-robin-map", but CMake did not find one.
Could not find a package configuration file provided by "tsl-robin-map"
with any of the following names:
tsl-robin-mapConfig.cmake
tsl-robin-map-config.cmake
Add the installation prefix of "tsl-robin-map" to CMAKE_PREFIX_PATH or set
"tsl-robin-map_DIR" to a directory containing one of the above files. If
"tsl-robin-map" provides a separate development package or SDK, be sure it
has been installed.
Am I missing a step?
The second problem is that I get this warning:
CMake Warning at CMakeLists.txt:6 (message):
WARNING: It is strongly recommended that you compile with clang
The README.md file says:
If you have gcc and clang both installed, then cmake currently defaults to
selecting gcc. You should override this by adding `-DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang++` to your Objective-C flags.
But where do I put these flags? Somewhere in CMakeLists.txt? In one of the
numerous *.cmake files?

ulib under Ubuntu-24
-----------------------------
To user ulib with Linux you need to build your own gnustep installation
The ones shipped with the distributions is not supporting automatic
reference counting because its using the old objc runtime which does not support
ARC.
Here is how to get such a installation up and running under Debian 10 (codename
Buster)
First we need some basic tools and repository's set up
apt-get install --assume-yes \
apt-transport-https \
openssh-client \
vim \
dirmngr \
libsctp1 \
lksctp-tools \
acpid \
wget \
telnet \
sudo \
locales-all \
net-tools
wget -4 -O - http://repo.gnustep.ch/key.asc >
/etc/apt/trusted.gpg.d/repo.gnustep.ch.asc
wget -4 -O - http://repo.universalss7.ch/debian/key.asc >
