Hi, I am Building Cbc and when execute:

~/coinbrew-master/coinbrew build Cbc --prefix=/home/jzazueta/lib –test

Appears the following error:

May you help me?

I can't replicate, so you'll have to provide more information. By the way, you still have a wrong character above ("–test"), would be nice to know where that's coming from. --test is now deprecated in favor of --tests which takes arguments 'main, all, or none. The default is "all".

Oh , just saw that you copied from Word. Yes, Word will auto-correct -- to a long dash, you definitely should not copy commands into Word and then back out again.

Hi tkralphs,

I am running with Centos 7 over Virtualbox:

As you see from history

284 cd dependencies/ 285 ~/coinbrew-master/coinbrew build Cbc --prefix=/home/jzazueta/lib --test 286 history | tail

The command is typed correctly. As you suggested, I typed: $ ~/coinbrew-master/coinbrew build Cbc --prefix=/home/jzazueta/lib --tests Deploys: Welcome to the COIN-OR fetch and build utility

For help, run script with --help.

No argument specified with --test.

Best Regards Juan Carlos

Looks like the old stdc++ of GCC 4.8 has some problems with that code. Not sure it's worth to work around issues with such an old compiler.

[jczazueta]

May I upgrade to gcc-8.2.0?

[tkralphs]

You should have no problems with any recent version of gcc.

[jczazueta]

Well I going to try.

In response to https://github.com/coin-or/CoinUtils/issues/128#issuecomment-611193221, the new option --tests takes an argument, which is one of main, all, or none. You need to specify one of those. The default is now all. If you want to replicate the old behavior of --test, you do --tests main. I updated the error message for not providing an argument, which was a bit confusing.
