This is an attempt to make the original Perl Kit, Version 1.0 to build correctly on recent Linux and *BSD. The original README file shipped with Perl has been moved to README.perl.txt.

This project is a remake of https://github.com/rhaamo/perl1. Here we try harder not to change the original source code and keep the original build system, since building is half of the fun :)

Building

The building process has three steps:

1. ./Configure (answer all the questions)
2. make depend (maybe a lot of warnings)
3. make (expet a lot of warnings)

On success the last line should be

touch all

You can then enjoy ./perl.

But most of the time you'll run into errors depending on your system and how clever were your answers in the Configure step. Instead of trying to give fixes for every system, here is a list of solutions for the most common errors (in order from the most expected to the least).

undefined reference to `crypt'

Fix:

At the Configure step try to add -lcrypt to the additional ld flags:

Any additional ld flags? [none] -lcrypt

If you still get the error, your compiler / linker is picky about flags order. Edit the Makefile and add -lcrypt manually to the libs make variable.

perl.y:73.1-5: syntax error, unexpected %type, expecting string or char or identifier

You're using bison as yacc and it doesn't like perl.y.

Fix:

Install a Berkley Yacc (for example byacc under Debian) and then modify Makefile:

% sed -i.bak -e 's/yacc/byacc/' Makefile

error: conflicting types for 'memcpy' (and a lot of noise)

perl.h #define bcopy which means trouble if a header (like good ol' <strings.h>) try to declare it.

Fix:

In the Configure step add the -DBCOPY to additional cc flags:

Any additional cc flags? [none] -DBCOPY

What is the full name of your C library?

the Configure step might fail to locate your C library. It happens for example on Ubuntu x86_64 because of their Multiarch design.

Fix:

Just figure out where is your system's libc and tell Configure.
