gmp-ecm is missing after install

[Jeffrey Walton]

I've installed gmp-ecm on disco, but it is missing after install:

$ sudo apt-get install gmp-ecm

gmp-ecm is already the newest version (7.0.4+ds-5).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

$ gmp-ecm 123456789
gmp-ecm: command not found

According to http://archive.ubuntu.com/ubuntu/pool/universe/g/gmp-ecm/gmp-ecm_7.0.4+ds-5.dsc, the package includes gmp-ecm:

  Binary: gmp-ecm, libecm1, libecm1-dev, libecm1-dev-common, libecm-dev

And:

  Package-List:
   gmp-ecm deb math optional arch=any
   libecm-dev deb oldlibs optional arch=all
   libecm1 deb libs optional arch=any
   libecm1-dev deb libdevel optional arch=any
   libecm1-dev-common deb libdevel optional arch=all

I'm guessing gmp-ecm got renamed somewhere along the lines, but the rename is not documented. It may be a good idea to list the binary's name in "Binaries" section.

$ lsb_release -a

Thanks for reporting.

The line
  Binary: gmp-ecm, libecm1, libecm1-dev, libecm1-dev-common, libecm-dev
refers to the binary packages built by this source package. In other words, the gmp-ecm source is used to create these multiple installable packages.

The executable binaries are part of the packages, but they don't necessarily share the same name. Looking at the gmp-ecm package in question [1], I see that it contains a binary named `ecm`. This might be the executable you are looking for. :)
