AUTO on mac

I'm going to write some memos about how to install AUTO on your new macOS. Here I consider clean installed macOS Big Sur (11.5.2). I don't know very well about Apple Silicon mac because I don't have it. But I am pretty sure it will run.

At first, you have to install Xcode app from AppStore. Also, you have to launch it once because it will install some stuff during its first launch.

I believe the following is an AUTO original HP.

 http://indy.cs.concordia.ca/auto/

Now, the source code of AUTO is maintained on GitHub.

https://github.com/auto-07p

You can download newest release from following link.

https://github.com/auto-07p/auto-07p/releases/tag/v0.9.3

You should download following file and extract in appropriate folder.

auto-0.9.3.tar.gz

Then launch the Terminal app, then change directory in to the auto/07p folder. Then type a following command in a Terminal app.

./configure 

You may see following error messages.

checking for Fortran flag to compile .f90 files... unknown

configure: error: Fortran could not compile .f90 files

It says that you do not have Fortaran 90. So, you should install it. You can download from following URL.

http://gcc.gnu.org/wiki/GFortran

Form Download ->  Binaries , you will arrive following URL. Then you can download dmg file.

https://github.com/fxcoudert/gfortran-for-macOS/releases

After installing the gfortran, on Terminal app, type the following command again.

./configure

 This time, you may see following messages.

***************************************************

It was requested that the plotting utility PLAUT04 

be compiled but the proper libraries (Coin3D and   

SoQt or SoXt or Open Inventor and Open Inventor Xt)

and perhaps Motif libraries (libXm) could not be   

found. The compilation of PLAUT04 is disabled.     

***************************************************

It says that if you want to install PLAUT04 software, you have to install additional dependent software. However, it is not necessary to install now. So, ignore it, and proceed now.

Then, on Terminal,  type following command.

make

You may meet following error messages.

gfortran -g -O autlab.f90 utility.o -o ../bin/autlab

ld: library not found for -lSystem

collect2: エラー: ld はステータス 1 で終了しました

make[1]: *** [../bin/autlab] Error 1

make: *** [util] Error 2

In the case, you should type following command on Terminal.

xcode-select --install

This  command install something important. It takes long time, just wait. 

Then, make again. I believe you will succeed to build newest AUTO finally.

OK, try the demo on an AUTO manual.  Download a newest manual (auto.pdf) from following URL.

https://github.com/auto-07p/auto-07p/releases/tag/v0.9.3

I am going to try  12.2 cusp.  Make a temporally folder and enter it.

mkdir tmp

cd tmp

Run auto.  (This notation is depended on where you are. )

../bin/auto

 Then, you can see like following.

daishin@mac tmp % ../bin/auto

Follow the tutorial, then I can see following bifurcation diagram etc. So, it works!
