问题

I'm having a tough job trying to get GD installed. I'm running a Mas OSX 10.9.2 darwin 13.0.1 When I run this: cpan[1]> install GD perl -MCPAN -e shell

I get the follwing error:

cpan[1]> install GD

回答1:

Build.PL is trying to call a function called prompt but it doesn't exist. This is because they recently switched build systems from ExtUtils::MakeMaker (Makefile.PL) to Module::Build (Build.PL) but didn't fully convert the program. I've reported the bug.

Most people don't notice this because the prompting is only necessary if GD can't configure itself. It does this by looking for the gdlib-config program. If that can't be found, or it doesn't work, it will ask you for your gdlib configuration. It's best to let gdlib-config take care of that. Best way to solve this problem is to make sure gdlib-config is somewhere in your PATH and that gdlib-config --all works.

Otherwise replace all the instances of prompt in Build.PL with Module::Build->prompt and it should work.

I'm not sure about doing this on OSX, but I recently had similar problems with installing CPAN modules on CentOS.

Some prerequisite modules simply wouldn't install properly from CPAN. These modules had RPMs available. After installing some of the prerequisites via yum, I was able to get CPAN to install the modules I needed.

In particular, I had to install Module-Build and Archive-Tar (which brought in a number of other dependency rpm's) using yum.

Hope this helps.
