[Cbc] [External] Re: 2.10 version on Ubuntu

Fri Sep 13 05:45:43 EDT 2019

Hi Ted,

Was able to install basis the commands what you and JP have helped with!

But now I am facing an issue that lapack installation fails throwing 403 error. Had also seen this happen with mumps (it was skipping earlier though).

On a separate note, want to confirm if I use --enable-cbc-parallel while configuring, I still see only one core getting used?

Thanks,

Subject: [External] Re: [Cbc] 2.10 version on Ubuntu

Just to close the loop, I made some additional improvements based on JP's feedback. ldconfig is now run automatically after the install on Linux whenever the install directory is not writable. It turns out that ldconfig is run automatically by libtool EXCEPT in the case of installing a directory that is in the system default library path. There doesn't seem to be a very good reason for this, but that's what it is.

I added some additional output explaining this and also changed the default verbosity level to 1 to remove some of the visual chaff.

By the way, another useful tidbit is that the default version that is fetched is the git master version, which is the development version (under our current workflow). The script now suggests that you might want to try the latest release, which you can get with

coinbrew fetch Cbc:releases/2.10.3 --no-prompt

Have fun!

Cheers,

Ted

JP,

A huge thanks to you, too, for the feedback. It helps a lot hearing from people who are using these tools, especially as they are in development. I actually don't have too much occasion to install to /usr/local, as I've always got many different builds that I'm working with locally. It helps to know what the experience is like for someone who just wants to install in /usr/local and leave it. I thought we were actually embedding the location of the libraries in the binary and that this issue shouldn't come up. I'll check into why that doesn't seem to be working.

For posterity, a general solution to your issue would have been to add

export LD_LIBRARY_PATH=/usr/local/lib

to your ~/.bashrc, which should work on any platform. The ldconfig solutions is easier on Ubuntu, but it is only a bit of luck that it works because /usr/local/lib is listed in /etc/ld.so.conf.d/libc.conf.

I'm going to update the documentation and also put some messages into coinbrew itself to prompt people to what to do if they encounter this issue. Thanks again for your feedback!

Cheers,

Ted

Hi Ted,

Everything is now building and running.
A huge thank you for your help.

After successfully doing the install with
sudo ./coinbrew install Cbc
the cbc standalone executable was not running (even after rebooting the machine).
Here is what happened:
jpfasano at WitOpenSource:~/coinCbc$ cbc
cbc: error while loading shared libraries: libCbcSolver.so.0: cannot open shared object file: No such file or directory
After googling around I found that the command
sudo /sbin/ldconfig -v
fixed the problem (web page link<https://itsfoss.com/solve-open-shared-object-file-quick-tip/>).

So in summary, these are the commands that worked for me (with a lot of your help) to checkout and build Cbc:

  *   wget https://raw.githubusercontent.com/coin-or/coinbrew/master/coinbrew
  *   chmod +x coinbrew
  *   ./coinbrew fetch Cbc
  *   ./coinbrew build Cbc --no-prompt --prefix=/usr/local
  *   sudo ./coinbrew install Cbc
  *   sudo /sbin/ldconfig -v

Thanks. I don't think I could have figured this out without your help.

Ah, yes, forgot to back out one change. If you just pull the changes, the install should work now, no need to rebuild.

And thanks very much for posting the complete log of the build each time! That makes it immensely easier to tell what's going on.

If you want to suppress the output once everything is working, you can use --verbosity 1 or -v 1 to just get minimal output.

Hi Ted,
"./coinbrew build Cbc --no-prompt --prefix=/usr/local" works great now!
Very impressive.
There is a lot going on.

>  sudo ./coinbrew install Cbc

Thank you for sending this additional command.
Your timing was perfect, because I had just realized that the built libraries and executables were still in my local directories. I was trying to figure out what needed to be done next, when your posting arrived.

Something with the "sudo ./coinbrew install Cbc"  isn't working for me.
Here is the console log:
jpfasano at WitOpenSource:~/coinCbc$ sudo ./coinbrew install Cbc
[sudo] password for jpfasano:
Welcome to the COIN-OR fetch and build utility

For help, run script with --help.
