build2 build system
This package contains the build2 build system.
build2 is an open source, cross-platform toolchain for building and packaging
C++ code. Its aim is a modern build system and dependency manager for the C++
language that provide a consistent, out of the box interface across multiple
platforms and compilers. For more information see:
https://build2.org/

Changes
Version 0.15.0
* Generated C/C++ headers and ad hoc sources are now updated during match.
Specifically, all headers as well as ad hoc headers and sources are now
treated by the cc::link_rule as if they had update=match unless explicit
update=execute is specified (see below on the update operation-specific
variable).
This change should be transparent to most projects. For background and
discussion of rare cases where you may wish to disable this, see:
https://github.com/build2/HOWTO/blob/master/entries/handle-auto-generated-headers.md
* Support for rule hints.
A rule hint is a target attribute, for example:
[rule_hint=cxx] exe{hello}: c{hello}
Rule hints can be used to resolve ambiguity when multiple rules match the
same target as well as to override an unambiguous match.
In cc::link_rule we now support "linking" libraries without any sources or
headers with a hint. This can be useful for creating "metadata libraries"
whose only purpose is to convey metadata (options to use and/or libraries
to link).
* UTF-8 is now the default input/source character set for C/C++ compilation.
Specifically, the cc module now passes the appropriate compiler option
(/utf-8 for MSVC and -finput-charset=UTF-8 for GCC and Clang) unless a
custom value is already specified (with /{source,execution}-charset for
MSVC and -finput-charset for GCC and Clang).
This change may trigger new compilation errors in your source code if
it's not valid UTF-8 (such errors most commonly point into comments).
For various ways to fix this, see:
https://github.com/build2/HOWTO/blob/master/entries/convert-source-files-to-utf8.md
* Project configuration variables are now non-nullable by default.
A project configuration variable with the NULL default value is naturally
assumed nullable, for example:
config [string] config.libhello.fallback_name ?= [null]
Otherwise, to make a project configuration nullable use the `null`
variable attribute, for example:
config [string, null] config.libhello.fallback_name ?= "World"
* New $relative(<path>, <dir-path>) function.
* New $root_directory(<path>) function.
* New $size() function to get the size of string, path, dir_path.
* New $size() function to get the size of a sequence (strings, paths, etc).
* New $sort() function to sort a sequence (strings, paths, etc).
The function has the following signature:
$sort(<sequence> [, <flags>])
The following flag is supported by all the overloads:
dedup - in addition to sorting also remove duplicates
Additionally, the strings overload also support the following flag:
icase - sort ignoring case
Note that on case-insensitive filesystems the paths and dir_paths
overloads' order is case-insensitive.
* New $config.origin() function for querying configuration value origin.
Give a config.* variable name, this function returns one of `undefined`,
`default`, `buildfile`, or `override`.
* Recognition of -pthread as a special -l option in *.libs.
For background, see:
https://github.com/build2/HOWTO/blob/master/entries/link-pthread.md
* The bin.whole (whole archive) value is now saved in generated pkg-config
files.
* Ability to customize header and library search paths in generated
pkg-config files.
Specifically, {cc,c,cxx}.pkgconfig.{include,lib} variables specify header
(-I) and library (-L) search paths to use in the generated pkg-config
files instead of the default install.{include,lib}. Relative paths are
resolved as installation paths. For example:
lib{Qt6Core}: cxx.pkgconfig.include = include/qt6/
* Ability to save user metadata in C/C++ libraries, including in generated
pkg-config files.
For background and details, see:
https://github.com/build2/HOWTO/blob/master/entries/convey-additional-information-with-exe-lib.md
* Support for rule-specific search in immediate import.
We can now nominate a rule to perform the rule-specific search (if
required) using the rule_hint attribute. For example:
import! [metadata, rule_hint=cxx.link] lib = libhello%lib{hello}
* Support for dynamic dependencies in ad hoc recipes.
Specifically, the `depdb` builtin now has the new `dyndep` command that
can be used to extract dynamic dependencies from program output or a
file. For example, from program output:
obje{hello.o}: cxx{hello}
{{
s = $path($<[0])
o = $path($>)
