Problem with ILOG_CPLEX_PATH

[zahra fatahi]

To whom it may concern,

I have a problem installing cplex with Cobra toolbox

From the following link, I downloaded CPlEX

\https://ibm.ent.box.com/s/rsiksgbyhcxjnindzq39sfdhhrrj7l11

Then I get cplex_studio2010-osx, and by clicking on it, I install CPLEX_Studio_Community201 in the Application folder, then in terminal, I use

$ nano ~/.bashrc

And then change 

export ILOG_CPLEX_PATH=“export ILOG_CPLEX_PATH="/Applications/CPLEX_Studio_Community201"

Then control X, Yes, and the enter. Then I did 

$ source ~/.bashrc

Afterwards, in Matlab I did

 initCobraToolbox

 But still I saw 

ibm_cplex   active        0     0     0     0     -     -

Then I restart Matlab, my computer, but nothing was changed. 

Then I tried to use 

>> updateCobraToolbox() 

But I get the following error

> Checking for available updates ... fatal: not a git repository (or any of the parent directories): .git > The SHA1 of the last commit could not be retrieved.fatal: not a git repository (or any of the parent directories): .git Warning: The name of the current feature (branch) could not be retrieved. > In updateCobraToolbox>getCurrentBranchName (line 198) In updateCobraToolbox (line 34) > You cannot update your fork using updateCobraToolbox() because this is a development branch. > The current branch is: fatal: not a git repository (or any of the parent directories): .git

 Unrecognized function or variable 'lastCommit'. Error in updateCobraToolbox (line 168) fprintf('%s\n',['> The last commit to the current branch is: ' lastCommit]) 

Then again I reinstall Cobra and again install it, but still, I do not have the IBM-cplex installed, and also again when I use the command updateCobraToolbox(), again I got the same error.

I would be so thankful if you kindly guide me on how can I fix this problem?

My system is 

macOS Catalina, version 10.15.7

Best regards,

Zara

Thats a bug. In updateCobraToolbox, replace:

if status_gitLastCommit ~= 0
fprintf(result_gitLastCommit);
fprintf(' > The SHA1 of the last commit could not be retrieved.');
else
lastCommit = result_gitLastCommit(1:6);
end

with

if status_gitLastCommit ~= 0
fprintf(result_gitLastCommit);
fprintf(' > The SHA1 of the last commit could not be retrieved.');
lastCommit = [];
else
lastCommit = result_gitLastCommit(1:6);
end

Also, see this message from a while back...

Dear All,

for those of you who do not know, IBM have decided not to release a
MATLAB interface to the new version 20.1 of CPLEX. The previous
version of CPLEX (12.10) can still be downloaded and used, apparently
for the next 5 years.
https://www.ibm.com/support/pages/downloading-ibm-ilog-cplex-optimization-studio-v12100

Please would everyone that uses CPLEX via MATLAB go to this page
https://ibm-data-and-ai.ideas.aha.io/ideas/CPLEX-I-112
and request that IBM bring back the MATLAB interface?

I realise that lots of people use gurobi, and others use TOMLAB (a
matlab interface) to access CPLEX, but we should not depend too much
on fewer solvers and CPLEX is still a very powerful solver.

Make your voice heard. Please go to this page and request the
restoration of the MATLAB interface...

Regards,

Ronan

Dear Ronan,

Thank you for your help, I did debug the cobraupdate. But for downloading the CPLEX it navigates me to this page 

https://www-112.ibm.com/software/howtobuy/passportadvantage/paoreseller/blueid/Entitlement?jadeAction=DISPLAY_SELF_NOMINATION

which needs Cite number and business justification that I do not access.

Best regards,

Zara
