### For distributors and developers
|
||||
- The autotools-based build system and legacy Xcode build systems have been removed, leaving only the CMake build system. All distributors and developers must migrate to the CMake build.

Compiling fish requires:
|
||||
|
||||
* a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later)
|
||||
* any of CMake, GNU Make, or (on macOS only) Xcode
|
||||
* CMake (version 3.2 or later)
|
||||
* a curses implementation such as ncurses (headers and libraries)
|
||||
* PCRE2 (headers and libraries) - a copy is included with fish
|
||||
* gettext (headers and libraries) - optional, for translation support
|
||||
|
||||
Additionally, if compiling fish with GNU Make from git (that is, not from an officially released tarball), `autoconf` 2.60+ and `automake` 1.13+ are required. Doxygen (1.8.7 or later) is also optionally required to build the documentation from a cloned git repository.

### Help, it didn't build!
|
||||
|
||||
If fish reports that it could not find curses, try installing a curses development package and build again.

On Debian or Ubuntu you want:

sudo apt-get install build-essential cmake ncurses-dev libncurses5-dev libpcre2-dev gettext

# SYNOPSIS
|
||||
#
|
||||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the specified
|
||||
# version of the C++ standard. If necessary, add switches to CXX and
|
||||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
|
||||
# or '14' (for the C++14 standard).
|
||||
#
|
||||
# The second argument, if specified, indicates whether you insist on an
|
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
|
||||
# -std=c++11). If neither is specified, you get whatever works, with
|
||||
# preference for an extended mode.
|
||||
#
|
||||
# The third argument, if specified 'mandatory' or if left unspecified,
|
||||
# indicates that baseline support for the specified C++ standard is
|
||||
# required and that the macro should error out if no mode with that
|
||||
# support is found. If specified 'optional', then configuration proceeds
|
||||
# regardless, after defining HAVE_CXX${VERSION} if and only if a
|
||||
# supporting mode is found.

# SYNOPSIS
|

#
|
||||
# AX_CXX_COMPILE_STDCXX_11([ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the C++11
|
||||
# standard; if necessary, add switches to CXX and CXXCPP to enable
|
||||
# support.
|
||||
#
|
||||
# This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
|
||||
# macro with the version set to C++11. The two optional arguments are
|
||||
# forwarded literally as the second and third argument respectively.
|
||||
# Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
|
||||
# more information. If you want to use this macro, you also need to
|
||||
# download the ax_cxx_compile_stdcxx.m4 file.
