You can find an overview of how to build plptools on the project README. This page attempts to provide additional platform-specific build information.

Building for macOS can be a little awkward as Xcode ships some CLI tools, necessitating a some path manipulation to ensure the correct tools are used over Xcode's built-in versions.

1. Bootstrap and configure the project:

   PATH="$(brew --prefix coreutils)/libexec/gnubin:$(brew --prefix m4)/bin:$PATH" ./bootstrap --skip-po
   CPPFLAGS="-I$(brew --prefix gettext)/include -I$(brew --prefix readline)/include" LDFLAGS="-L$(brew --prefix gettext)/lib -L$(brew --prefix readline)/lib" ./configure

2. Then make:

   make

Building on Haiku works with some caveats. There is a small bug with RegEx that makes ./configure crash (see https://github.com/plptools/plptools/issues/23), which can be worked around with --with-included-regex.

1. Install prerequisites:

   pkgman install libtool gnupg gettext readline_devel

2. Bootstrap and configure:

   ./bootstrap --skip-po
   ./configure --with-included-regex

3. Then make:

   make

• Haiku's usb_serial drivers do not implement RS232 hardware control lines (see https://dev.haiku-os.org/ticket/19622), so USB RS232 adapters won't work with plptools. Physical serial ports work fine.
• plpfuse won't compile when userland_fs is installed (if it isn't installed, plpfuse is skipped).

• m4
• libtool
• gnupg
• pkgconf
• automake
• autoconf
• gettext
• gmake (otherwise man files won't build)

./bootstrap --skip-po
LDFLAGS="-L/usr/local/lib/" ./configure
gmake

• m4
• libtool-2.4.7
• gnupg-1.4.23nb23
• pkgconf
• autoconf
• automake
• gettext-0.22.5
• coreutils (for buiilding):
  • gnulib/gnulib-tool: 'join' program is buggy. Consider installing GNU coreutils.
• gmake (otherwise man files won't build)

./bootstrap --skip-po
LDFLAGS="-L/usr/pkg/lib -Wl,--rpath=/usr/pkg/lib" ./configure
gmake

• m4
• libtool
• gnupg
• autoconf
• automake
• gettext-tools
• readline
• gmake (otherwise man files won't build)

./bootstrap --skip-po
CPPFLAGS="-I/usr/local/include/ereadline/" ./configure
gmake

On a fresh build, you need to set AUTOCONF_VERSION and AUTOMAKE_VERSION environment variable.

export AUTOCONF_VERSION="2.72"
export AUTOMAKE_VERSION="1.18"
