Compiling on Apple M1

Question

Hi,

I need to compile openCARP on a machine with Apple M1 chip. I followed the instruction in one of the previous answers ( https://opencarp.org/q2a/189/compiling-opencarp-on-an-apple-m1-machine?show=189#q189 ), but I still have errors. Here I report what I get:

The commands I provided are

cmake -S. -B_build -DDLOPEN=ON -DCMAKE_BUILD_TYPE=Release -D CMAKE_C_COMPILER=llvm-gcc -D CMAKE_CXX_COMPILER=llvm-g++

cmake --build _build

with last part of the output (just before the error)

[ 80%] Building CXX object CMakeFiles/opencarp-bin.dir/simulator/main.cc.o

[ 80%] Linking CXX executable bin/openCARP

ld: library not found for -lLIB_gfortran-NOTFOUND

clang: error: linker command failed with exit code 1 (use -v to see invocation)

gmake[2]: *** [CMakeFiles/opencarp-bin.dir/build.make:124: bin/openCARP] Error 1

gmake[1]: *** [CMakeFiles/Makefile2:336: CMakeFiles/opencarp-bin.dir/all] Error 2

gmake: *** [Makefile:156: all] Error 2

From the output of ccmake _build I found I miss other dependencies I do not know how to link:                                                      

 LIB_emutls_w  LIB_emutls_w-NOTFOUND  

[...]

LIB_gfortran      LIB_gfortran-NOTFOUND

[...]

LIB_quadmath   LIB_quadmath-NOTFOUND                                                                                                

Thank you in advance,

Edoardo

Ok, I thought I found a workaround. I don't know if it is "best practice".

I just added to the PATH the outputs of

find /opt/ -iname '*libraryname*'

with libraryname={emutls,gfortran,quadmath}

Many possible paths where given, I added the ones similar to /opt/homebrew/lib/gcc/current (unfortunately I could not find any of the libraries in paths relative to llvm). Then I gave the usual commands to compile through cmake and it worked.

It is also important to add the line

export DYLD_LIBRARY_PATH=/path/to/these/libraries

to $HOME/.zshrc

in order not to have further issues when running openCARP and be sure that everything is dynamically linked fine.

Let me know if something more "canonical" exists.

Hi,

I have the same issue with installing openCARP on mac M1.  I couldn't solve the problem with the suggested solution.

I appreciate any help or suggestion.

Hi,
Have you checked, from the openCARP _build folder, that `ccmake .` outputs that everything is set up properly? In particular check for the LIB_gfortran entry, modify it and press c to restart the configuration phase of cmake. Try to do the same also for emutls and quadmath.
Alternatively, you could just purge your _build folder, update all the paths as indicated and then start again the configuration from scratch and try to compile openCARP if configuration goes smoothly

Best,
Edoardo

Hi Edoardo,
Thanks, you are right, by  removing _build and manually adding some of the settings in ccmake,  I was able to compile openCARP smoothly.  

However, I am struggling to install carputils,  was wondering if you install carputil on M1 machine by following
https://opencarp.org/q2a/189/compiling-opencarp-on-an-apple-m1-machine?show=189#q189)?

No, I did not try to install carputils on M1. The carputils installation I use is on a Linux machine. You can open a new question with your error for carputils
