How To Install/Update CPAN on MacOS Mojave with fatal error: ‘EXTERN.h’ file not found

Author: erics, June 12th, 2019

The Problem Tried to install the latest version of cpan and got stuck. Tracked it down to the dependency module Mac::SystemDirectory which was failing to build:

cpan[1]> install Mac::SystemDirectory

The Solution Use the MacOS installer command to deploy the needed files:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
installer: Package name is macOS_SDK_headers_for_macOS_10.14
installer: Installing at base path /
installer: The install was successful.

installer: Package name is macOS_SDK_headers_for_macOS_10.14

installer: Installing at base path /

installer: The install was successful.

The, rerunning the cpan install works:

cpan[1]> install Mac::SystemDirectory

How To Fix MySQL Remote Login Errors

Author: erics, August 25th, 2016

In this case I had done a restore from a MySQL 5.1 server to a MySQL 5.6 server. That was not too smart, because it broke the mysql database table structures and prevented me from logging in remotely. Local login worked both via the socket and TCP. mysql -u root -p -h remoteHostName Enter password: […]

How To Create a Code Block in PHP for Error Handling

Author: erics, October 19th, 2012

The do/while statement is sometimes used to break out of a block of code when an error condition occurs. For example:

do {
  // do some stuff
  if ($error_condition)
    break;
  // do some other stuff
} while (false);

1

2

3

4

5

6

do {

// do some stuff

if ($error_condition)

break;

// do some other stuff

} while (false);

Because the condition for the loop is false, the loop is executed only once, regardless of what happens inside the loop. However, if an error occurs, the code after the break is not […]
