CPAN Installation of Perl Packages Fails

m_jaser has asked for the wisdom of the Perl Monks concerning the following question:

Hello Perl Monks

I've been trying to install some perl packages via CPAN but its failing, see the examples below for your reference. Can you please advise how can I successfully install these packages?

[~]$ cpan -f -i Device::SerialPort
Going to read '/home/emarwja/.cpan/Metadata'
  Database was generated on Thu, 22 Jun 2017 02:17:02 GMT
Running install for module 'Device::SerialPort'
Running make for C/CO/COOK/Device-SerialPort-1.04.tar.gz

+erialPort-1.04.tar.gz ok

  CPAN.pm: Going to build C/CO/COOK/Device-SerialPort-1.04.tar.gz

To enable serial port tests, use:
        perl Makefile.PL TESTPORT=<DEVICE>
where <DEVICE> is a specific port or 'auto' to autodetect.
Running ./configure ...
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
The 'configure' script didn't like something.  It should have told you
what went wrong, but you can check 'config.log' for more details.

Hello m_jaser, According to this line in your output, `configure: error: no acceptable C compiler found in $PATH` [download] you don't have a C compiler installed (which is needed by Device::SerialPort). Some (but not all) modules require a C compiler. Module names are case-sensitive. So, your attempts to install Net::SSH and Net::Telnet failed because `cpan` could not find the modules. Also, you should not need to use the `-f` flag in most cases. After you install a C compiler, you may want to try the following. `cpan -i Net::SSH cpan -i Net::Telnet` [download] If you want more specific advice on how to fix these problems, then please let us know which operating system you are running and which version of perl you are running.

If you want more specific advice on how to fix these problems, then please let us know which operating system you are running and which version of perl you are running. To get information about perl: `perl -v` To get much more information about perl: `perl -V` To get information about the operating system: `uname -a` In case of Linux, also try: `ls /etc/version` and if that lists a file, show its content: `cat /etc/`some-linux-distro-name`-version` Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l] [select]
