Contains the UnixCCompiler class, a subclass of CCompiler that handles
|
the "typical" Unix-style command-line C compiler:
|
* macros defined with -Dname[=value]
|
* macros undefined with -Uname
|
* include search directories specified with -Idir
|
* libraries specified with -lllib
|
* library search directories specified with -Ldir
|
* compile handled by 'cc' (or similar) executable with -c option:
|
compiles .c to .o
|
* link static library handled by 'ar' command (possibly with 'ranlib')
|
* link shared library handled by 'cc -shared'

For macOS, split command into 'env' portion (if any)
|
and the rest of the linker command.
|
|
>>> _split_env(['a', 'b', 'c'])
|
([], ['a', 'b', 'c'])
|
>>> _split_env(['/usr/bin/env', 'A=3', 'gcc'])
|
(['/usr/bin/env', 'A=3'], ['gcc'])

|
AIX platforms prefix the compiler with the ld_so_aix
|
script, so split that from the linker command.
|
|
>>> _split_aix(['a', 'b', 'c'])
|
([], ['a', 'b', 'c'])
|

|
The linker command usually begins with the compiler
|
command (possibly multiple elements), followed by zero or more
|
params for shared library building.
|
|
If the LDSHARED env variable overrides the linker command,
|
however, the commands may not match.
|
|
Return the best guess of the linker parameters by stripping
|
the linker command. If the compiler command does not
|
match the linker command, assume the linker command is
|
just the first element.
|
|
>>> _linker_params('gcc foo bar'.split(), ['gcc'])
|
['foo', 'bar']
|
>>> _linker_params('gcc foo bar'.split(), ['other'])
|
['foo', 'bar']
|
>>> _linker_params('ccache gcc foo bar'.split(), 'ccache gcc'.split())
|
['foo', 'bar']
|
>>> _linker_params(['gcc'], ['gcc'])

macOS users can specify an alternate SDK using'-isysroot'.
|
Calculate the SDK root if it is specified.
|
|
Note that, as of Xcode 7, Apple SDKs may contain textual stub
|
libraries with .tbd extensions rather than the normal .dylib
|
shared libraries installed in /. The Apple compiler tool
|
chain handles this transparently but it can cause problems
|
for programs that are being built with an SDK and searching
|
for specific libraries. Callers of find_library_file need to
|
keep in mind that the base filename of the returned SDK library
|
file might have a different extension from that of the library
|
file installed on the running system, for example:
|
/Applications/Xcode.app/Contents/Developer/Platforms/
|
MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/
|
usr/lib/libedit.tbd
|
vs

|
Second-guess the linker with not much hard
|
data to go on: GCC seems to prefer the shared library, so
|
assume that *all* Unix C compilers do,
|
ignoring even GCC's "-static" option.
