I am trying to build a project using cmake. however when cmake verifies whether I have a working c compiler it fails with the output:

ld: library not found for -lSystem
indeed, I do not have a libSystem.dylib installed on my Mac.
I am using clang 13 to build it.
deleting CommandLine tools directory and doing Xcode-select --install fixed the problem

I am using MacOS Mojave version 10.14.16 and I am trying to install http://www.rpl2.net/index.php (a programming language using Reverse Polish Notation as found on some HP calculators like the 48GX), supposed to work on MacOSX (they say "MacOS X (Xcode 3.1.4 + gfortran 4.5)").
So I have downloaded the latest stable release, cd to the folder, and wanted to run
./configure
make
make install
But the ./configure is failing due to "configure: error: Can not find libgomp !". There is no libgomp package I can install with brew (I already installed gcc which comes with gfortran and thought it would provide libgomp but apparently not).
Could someone help a poor applied mathematician trying to install a software on its macbook?
Thanks
EDIT
in my config.log I have this, maybe it will help:

You don't say how you installed GCC. If you did it using homebrew, and
brew install gcc
you should be able to see:
/usr/local/Cellar/gcc/10.2.0/lib/gcc/10/libgomp.dylib
which would mean you need to compile with:
gcc ... -L /usr/local/Cellar/gcc/10.2.0/lib/gcc/10 -l gomp ...
Failing that, you can always search for libgomp with:
find /usr -name "lib*gomp*lib"
You can test which gcc you are using with:
type gcc
I am trying to install OpenMP enabled xgboost on my mac. I installed gcc with no problem:
brew install gcc --without-multilib
then cloned git repository:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost; cp make/config.mk ./config.mk
but I get an error when I do
make -j4
Here is the error I get. I'd appreciate if you can help fixing this problem:

I have the same issue and solved it by:
brew install clang-omp
export CC=clang-omp
export CXX=clang-omp++
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost; cp make/config.mk ./config.mk; make -j4
cd python-package
sudo python setup.py install
If you used pip to install xgboost before, then delete the previous installed xgboost from your project. Then use
pip install xgboost
to install it again.
A new versions of OSX has a Clang as a default c\c++ compiler. Therefore your c++ command refers to clang++.
You should define a CC\CXX environmental variables for your make command like this CC=gcc CXX=g++ make -j
Also you can build an OpenMP for clang OpenMPrt and customise your shell environment (I didn't try this by own)
(I have no mac at this moment to check this solution; just linux)
I am trying to install a python module (SPArse Modeling Software) but the install script doesn't seem to be able to find the system's default Python.framework. This is an almost new (no migration assistant) Mac OS 10.9.5 system with both the default system python and Anaconda installed. I briefly installed Enthought Canopy but removed it when I decided to go with Anaconda. /System/Library/Frameworks/Python.framework exists and seems to have all the files you would expect.
In terminal, this is what happens:
bash-3.2$ which python
//anaconda/bin/python
bash-3.2$ cd spams-python
bash-3.2$ python setup.py build
running build
running build_py
running build_ext

ld: framework not found Python
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So, my question is, is my diagnosis of the problem correct? How can I tell GCC where Python.framework is? Is there some environment variable that isn't set correctly?
The Anaconda Python is not a Framework build of Python. If the module expects that it's not going to work. Commenting out commenting out "'-framework', 'Python'" in setup.py sounds like a good start, and if it works, then it probably is the right solution.
Compile it with gcc-5, and I successed.
I took the following steps after reading suggestions from http://andhikalegawa.wordpress.com/2012/01/05/installing-mysql-python-on-snow-leopard-using-xampp-mysql/
Downloaded MySQL-python-1.2.4b4 and unzipped
Changed the mysql_config = /Applications/XAMPP/xamppfiles/bin/mysql_config (as I am using XAMPP 1.7.3)
Downloaded mysql-5.1.70-osx10.6-x86 (I could not find 5.1.55 which is the version used in XAMPP) kept the include folder at /Applications/XAMPP/xamppfiles/
I am new to development so, downloaded XCode 4.6.3 with command line tools.
Logically it should have worked I am getting the following error

Looks like it's trying to compile universal for PowerPC, which you probably don't have?
error trying to exec '/usr/bin/../llvm-gcc-4.2/bin/powerpc-apple-darwin11-llvm-gcc-4.2'
I would suggest setting the ARCHFLAGS:
shell> rm -Rf build/
shell> ARCHFLAGS="-arch i386" /usr/bin/python setup.py build
Or instead of i386, on 64-bit x86_64. But since you are downloading 32-bit MySQL, might be good to use i386.
Good luck! (Shameless advert: you can always try MySQL Connector/Python)
