This allows for much easier cross compiler configuration for tools like
LLVM. This patch does honor the 'native' keyword, and falls back to
searching PATH if the binary name is not specified.
I'd be fine with either removing the fallback behavior, or marking it as
deprecated and removing it later.
Fixes#2921
This replaces calls to .rstrip('git'), .rstrip('svn') with a regex that
takes the leading numbers and dots, and throws away the rest. This also
moves the code up to the ConfigToolDepdency level, since these config
tools are of various quality and some of them are good, and some are
not. This shouldn't affect well behaved tools.
This should future proof LLVM against future suffixes (like someone
doing something strange like using Mercurial as a VCS).
I'm not sure this is a good idea, but at the moment it seems a bit too easy
to write something like dep.get_pkgconfig_variable('inculdedir:') (sic) and
not notice it's not doing anything useful.
Create GL dependency objects via a factory function, so they can be the
correct type of object (e.g. a PkgConfigDependency when it's found by
pkg-config)
Factor out method: kwarg processing, so it can be used by the factory before
the dependency object is constructed
This code isn't used as present: the actual objects we use and which get
pickled are either static subclasses of ConfigToolDependency, or special
purpos subclasses of Dependency which get attributes copied from an instance
of a dynamic subclass of ConfigToolDependency which is then discarded.
This is fortunate, as it doesn't work: the pickled reduction is a call to
the dynamic subclass's constructor, but the superclass constructors rely on
the environment object being fully initialized, which hasn't happened yet
during unpickling.
Avoid this by having a pickled reduction which is just a call to create the
dynamic subclass object, and relying on the default __setstate__ behavior to
unpickle the object's __dict__.
Since this is only consulted while constructing the Dependency object, it's
result doesn't depend on the instance (and it would make no sense if it did)
Because FreeBSD's llvm-config adds -l/usr/lib/libexecinfo.so when asked
for system-libs, which is bogus. We'll remove the leading -l from any
argument that also ends with .so.
Special case ThreadDependency by taking compiler's flags and
PkgConfigDependency by adding them in requires(.private) instead. For
other Dependency objects just take their link_args and compile_args.
Closes#2725
If LLVM is built from a git mirror instead of from SVN it will have
"git-<very short sha>" at the end of the version. We need to remove that
so that version comparison will work correctly.
Fixes: #2786
Using NotImplementedError throws an ugly traceback to the user which
does not print the line number and other information making it
impossible to figure out what's causing it.
Also override it for internal dependencies because self.name is "null"
for them.
The sysconfig config variables are different on MSYS2 and the paths
are also different. We now also use the full path to the import or
static library instead of using -Lfoo -lpython35 etc.
Also obey the value of the 'static' keyword argument.
sysconfig.get_platform() returns 'mingw' with MSYS2, so we need to
use some other method; in this case I chose to use the CC that
Python was compiled with, which is a relatively reliably indicator
unless people start using Python on Windows compiled with Clang or
something.
