1.0.85

Important

This release has been yanked, due to panicking in freeBSD debug build. A release without these issues will be made in the near future.

Sorry, and thanks.

Full Changelog: 1.0.84...1.0.85

1.0.84

Important

This release has been yanked, due to the Apple deployment target changes causing unintentional widespread breakage for building C++ code on the target (for projects without an explicit deployment target set). A release without these issues will be made in the near future.

Sorry, and thanks.

Changes

This isn't a complete list, but I've tried to cover everything that is either significant, or could cause problems for people using cc in configurations not covered by our tests.

• The MSRV has been updated to 1.53.0 (#894)
• A completely overhauled implementation of the jobserver protocol (used under feature = parallel), which should be more efficient. (#889).
• Better handling of assemblers on windows targets, especially armasm[64].exe (#867, #868, #869, #857)
• A few fixes for incorrect results from is_flag_supported (#839, #886)
• Support for the *-apple-tvos and *-apple-tvos-sim targets (#881, #704)
• Improved handling of the deployment target on Apple targets, including use of rustc --print deployment-target when available (#848, #872)
• We no longer bundle bitcode when compiling for Apple targets, as they've deprecated it (#812)
• A new remove_flag function to remove flags which have been added with add_flag (#885)
• Changes to how clang and gcc are distinguished, and how -m32/-mx32/-m64 flags are passed (#709)
• Minor adjustments to how -isysroot is passed on Apple targets (#703) and how MSVC version is detected on Windows (#696).

As always, please file bugs if you hit issues. cc is used in many more ways than we can possibly test (especially when cross-compiling or using tier-3 platforms).

Thanks.

Full Changelog: 1.0.79...1.0.80

1.0.79

Version 1.0.79

Changelog

• The riscv32imc-esp-espidf target is now supported (#776)
• Build::is_flag_supported now checks the exit status of the compiler in addition to stderr output, improving reliability (#757)
• When building for the aarch64-apple-ios-sim target -arch arm64 is now correctly passed as two arguments instead of one (#759)
• Improved control over ar and ranlib (#763)
  • New functions to return the ar (Build::get_archiver) and ranlib (Build::get_ranlib) binaries used for this build have been added.
  • Several related environment variables involving the archiver and ranlib variant (ARFLAGS, RANLIBFLAGS, AR, and RANLIB) are now respected automatically if not overridden.
  • Some other changes too, see #763 for details.
• We will now correctly locate msbuild under VS2022 (#773)

---

Additionally, a number of smaller changes which shouldn't impact users have been made (in particular #769 and #777); see the commit history for complete details.

Thanks to everybody who contributed to this release!

1.0.78

Version 1.0.78

Changelog

• Now, only .asm files are passed to masm on windows targets, bringing things back in line with how cc-rs<1.0.77 handled it (#755).
• Absolute paths in source are now mapped as relative in OUT_DIR (#684)
• Several improvements were made to CUDA support (#712)
• llvm-lib.exe is now used instead of lib.exe when clang-cl is used in an MSVC environment (#758)

---

Thanks to everybody who contributed to this release!

1.0.77

Version 1.0.77

Changelog

• Added a new Build::asm_flag function, which allows providing flags that are only used when compiling assembly files (for example, if your C compiler rejects flags passed to the assembler when not used as an assembler). (#752)
• Ensure that the version of DWARF debuginfo we emit is consistent with what rustc uses on the given target. (#694)

---

Thanks to everybody who contributed to this release!

1.0.76

Version 1.0.76

Changelog

• When compiling with clang-cl, we now only use -- to separate flags/options from input files when not using the assembler, which doesn't support that option. This is a fix for a regression introduced in 1.0.74 (by #514) (present in 1.0.75 as well). (#747)

---

This is essentially a bugfix release, so that's all!
