Fix a libc++ include order issue in the Wrapper.
Fix for https://github.com/tpoechtrager/osxcross/issues/383
Introduce a complex C++20 test for SDK versions 13.3 and above, requiring Clang version 13.0 or higher.
Update the GCC version to 13.2.0 in the build_gcc.sh script.
I tried to follow the instructions outlined in PACKAGING THE SDK,
and as it turns out the instructions for Linux required more than
40GB of disk space. That's why I think it would be best to tell
readers that they might need up to 45GB of space rather than
up to 25GB. I'm not sure if the instructions are simply outdated
in this regard or if the space requirements are just different for
other reasons, however I highly suspect the former to be the case.
Being able to extract SDKs from Command Line Tools for Xcode instead
of the full Xcode package saves bandwidth, disk space, and time.
Two scripts are added:
* tools/gen_sdk_package_tools.sh: extracts SDKs from installed
Command Line Tools on macOS (/Library/Developer/CommandLineTools)
or from a path specified via XCODE_TOOLS_DIR
* tools/gen_sdk_package_tools_dmg.sh: unpacks the content of provided
Command_Line_Tools_for_Xcode.dmg and extracts SDKs via the above
script.
Tested with Command Line Tools for Xcode 12.x.
* Added support for TAPIv3 stubs (including "zippering" target)
* Added support for MacOSX SDKs up to 10.14
* Added new SDK packaging script for SDKs that end with ".xip" (tools/gen_sdk_package_pbzx.sh <xcode.xip>) (tested up to Xcode 10.2.1)
* Updated cctools to 921 and ld64 to 409.12
Fixed:
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/171
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/178
* Implemented fix for https://github.com/tpoechtrager/osxcross/issues/182
Changed:
* cctools, ld64, apple-libtapi and xar are now "git clone"'d and no longer come with OSXCross.
Removed:
* Support for Cygwin and *BSD (besides FreeBSD)
* Support for building OSXCross with GCC
Notes from Thomas Pöchtrager:
* The *-g++-libc++ aliases use the Clang C++ library.
* Don't use the Clang C++ library with GCC.
* You can use an installed Clang, or build your own.
* Same Clang serves both to compile OSXCross and as the cross-compiler.
* INSTALLPREFIX is specifically for installing a (native!) clang.
Other tweaks to the text:
* Broke some lines before 80 characters (found by lint check).
* Removed some trailing spaces (found by lint check).
* Put shell commands on their own, indendent lines.
* Explain GCC_VERSION, ENABLE_FORTRAN, etc. explicitly.
* Make each footnote its own paragraph, on a separate line.
* Minor tweaks to wording for style & idiom.
This finally adds support for Xcode 7 / El Capitan.
With this commit I am also removing ld64-134.9 support.
I kept ld64-134.9 for users with an old C++ standard library.
A decent C++ standard library with C++11 support is now mandatory.
it's simple, but I went around the project for a while until i figure out what the packaged SDK was. Didn't naurally want to continue reading until I understood that point.
* Support for generating fat object files with gcc and '-foc-use-gcc-libstdc++'
has been removed.
This feature was not 100% correctly implemented; using multiple source files
did not work, i.e.: 'o32-g++ -m32 -m64 a.cpp b.cpp' would have failed;
And I refuse to implement that, instead I am removing all source file handling
from the wrapper with this commit for simplicity.
This feature should be implemented in the gcc driver instead.
This does NOT affect clang's fat object file support, which is implemented in
clang's darwin driver.
* '-oc-use-gcc-lib' has been renamed to '-foc-use-gcc-libstdc++'.
* Added support for '-stdc++' and '-gstdc++' compiler "shortcuts"
o32-clang++ --> uses libstdc++ for <= 10.8 and libc++ for >= 10.9
o32-clang++-libc++ --> uses the SDK's libc++
o32-clang++-stdc++ --> uses the SDK's libstdc++
o32-clang++-gstdc++ --> uses gcc's (build_gcc.sh) libstdc++
* Entirely rewrote the command line parser; the previous one wasn't very
readable.
* Minor Readme Updates
* Added unit tests
* Removed OSXCROSS_C_STANDARD / OSXCROSS_CXX_STANDARD support
I am no longer parsing -std=, so this feature has to be dropped.
Setting the language standard via an env variable isn't a good idea anyway.
* Removed unneeded stuff
Other Changes:
* Version bump to 0.11
