v0.5.0§

2019-11-25

New features§

• Add generated_source() to allow generating source code from domain-specific languages
• Add support for lex, yacc, and Qt build tools (moc, rcc, uic)
• Add the ability to use placeholders for build_step() and command()
• Add an auto_file() function that infers the kind of file based on its extension; build_step() now uses this by default for outputs
• Add always_outdated argument to build_step()
• Add copy_file() and copy_files() functions
• default() now returns the files passed into it
• install() now returns the installed forms of the files passed into it
• Add safe_str() and safe_format() to help safely build command string
• Expose Path object to bfg scripts
• Add directory as an option for object_file(), generated_source(), copy_file(), and their list-variants
• Add lang and intermediate_dirs arguments to project() for modifying project-wide settings
• Add srcdir builtin to toolchain files

Breaking changes§

• find_files() redesigned and split into find_files() and find_paths(); simple cases should still work, but more complex uses will need adjusted
• pkg-config .pc files generated by bfg9000 no longer include rpath flags
• Explicitly passing lang to a build step now overrides the languages of any input files when determining the builder
• args and kwargs no longer supported for build_step(); use a lambda instead
• Options specified on the command line (e.g. install locations) now override settings in toolchain files
• Implicitly-defined object files (e.g. those generated by executable()) are placed in an intermediate directory; call project(intermediate_dirs=False) to disable this

Bug fixes§

• Include options.bfg in dist tarballs
• Fix escaping of ~ in Makefiles
• Symbolic links (e.g. from versioned shared libraries) are now properly installed as symlinks
• Generated header directories are now included as dependencies of compilation steps
• Default install locations are now based on the target platform instead of the host platform
• Shared libraries with soversions can now be used with pkg_config()

v0.4.1§

2019-07-05

Bug fixes§

• Fix using semantic options in global_options

---

v0.4.0§

2019-07-05

New features§

• Compilers and linkers now support semantic options, abstracting away the differences between compiler flavors
• Add support for cross-compilation
• Toolchain files can be used to simplify setting up build configuration options
• Add info, warn, and debug builtins to let build scripts print messages via bfg's logging system
• whole_archive() now works with MSVC linkers
• Add support for module-definition files when linking .exe or .dll files
• Build steps now have a (customizable) friendly description when using the Ninja backend
• Makefiles generated by bfg now have a clean target

Breaking changes§

• MSVC builds now automatically set /EHsc to improve standards-compliance and mimic Visual Studio's default MSBuild configuration
• Paths are now parsed in a platform-agnostic manner, which may cause issues for certain esoteric pathnames (e.g. POSIX paths that look like Windows paths)
• env.platform has been split into env.host_platform and env.target_platform
• MinGW now makes DLLs named <name>.dll instead of lib<name>.dll
• Platform names are reworked; 'windows' is now 'winnt' and 'darwin' is 'macos'

Bug fixes§

• Fix support for packaging as a Python Wheel
• Default options for ar are now cr instead of cru to support versions of ar that default to deterministic builds
• Fix building Java projects with OpenJDK 8+
• Fix loading Boost packages from C:\Boost on Windows
• Libraries are linked via their absolute paths where possible to help disambiguate libraries with the same name

---

v0.3.1§

2018-06-01

Bug fixes§

• Fix an issue with creating the build directory during the configuration process

---

v0.3.0§

2018-06-01

New features§

• Replace system_package() and pkgconfig_package() with a generic package resolver: package()
• Add headers argument to package() to find header files and libs to specify library names if pkg-config lookup fails
• Support Java/Scala
• Add support for user-defined arguments
• Add a library() function that builds shared and/or static libraries per the user's preference
• Add support for generating pkg-config .pc files
• Allow executing files that require an interpreter or other wrapper via command() or test()/test_driver() without explicitly specifying the wrapper; supports all languages buildable by bfg9000, plus Lua, Perl, Python, and Ruby
• Add env.run(), env.execute(), and env.run_arguments() to simplify executing programs during configuration
• Add a framework() function to specify macOS frameworks to use for a build
• Improve detection of compiler flavors by checking version information
• Automatically colorize clang/gcc output under Ninja
• Add support for uninstalling builds
• Add static_link_options to static_library() to specify options to pass to the static linker
• Add a bfg9000 env command to print the environment variables used during configuration
• Automatically request sudo elevation when installing builds to a system directory

Breaking changes§

• directory() and header_directory() no longer automatically include all files within them (pass include='*' for the old behavior)
• The include argument for compiling object files has been replaced by includes
• When creating a static library, link_options now specifies options that will be forwarded along to the dynamic linker, rather than options for the static linker itself
• The options argument for test()/test_driver() has been deprecated; add any options to the first argument (cmd) instead
• test() no longer converts its first argument to a generic_file()
• Splitting POSIX shell strings (used for compile and link options as well as environment vars on POSIX like CPPFLAGS) no longer parses escape characters

Bug fixes§

• Improve logging of syntax errors in build.bfg files
• Fix usage of nested shared libraries when linking with GNU ld (via -rpath-link)
• Installing directories from the srcdir now correctly installs their contents to the installation root for that type (e.g. a header directory of foo/bar installs its contents to $includedir)
• Fix generation of dependencies for the tests target
• Improve escaping for paths when using Make on Windows (previously users had to escape backslashes themselves)
• Fix an issue with quotation marks being stripped for some commands on Windows with the Ninja backend

---

v0.2.0§

2016-06-26

New features§

• Support Objective C/C++
• Partially support Fortran (simple projects work, but more complex things probably don't)
• Improved error reporting
• Warn users if necessary build tools can't be found by bfg9000
• Automatically include runtime dependencies when installing a binary
• Support @rpath on OS X
• Allow fetching bfg's version from build.bfg files via bfg9000_version
• Support versioning of shared libraries on POSIX systems
• Support resolving packages via pkg-config
• Locally-built static libraries now forward their options to binaries that link to them
• whole_archive() now forwards its arguments on to static_library()

• env.compiler(lang).flavor replaced by env.builder(lang).flavor

Bug fixes§
