Note that this is completely unrelated to gnu usage of libtool.
|

This doesn't need to exist in C & CXX.

This has outlived its usefulness, doesn't gel well with
newer compilers & `-flto` related options, i.e thin vs full, or `=auto`,
and having `-flto` as the only option means that sometimes this just
needs to be worked around, i.e in oss-fuzz:
https://github.com/google/oss-fuzz/blob/master/projects/bitcoin-core/build.sh.
While it was convenient when `-flto` was newer, support for `-flto` is now
in all compilers we use, and there's also no-longer any real need
for us to treat `-flto` different to any other optimization option.
Remove it, to remove build complexity, and so there's no need
to port a similar option to CMake.
Note that the LTO option remains in depends, because we still a way to
build packages that have LTO specific patches/options.
If we decide to merge this, I'll follow up downstream in oss-fuzz first,
to make sure we don't break the build.

```bash
-platform_version platform min_version sdk_version
This is set to indicate the platform, oldest supported version
of that platform that output is to be used on, and the SDK that
the output was built against.
```

`_LIBCPP_ENABLE_ASSERTIONS` is deprecated, and will be removed. [See (from libc++ __config in main)](https://github.com/llvm/llvm-project/blob/b57df9fe9a1a230f277d671bfa0884bbda9fc1c5/libcxx/include/__config#L205-L209):
> TODO(hardening): remove this in LLVM 19.
> This is for backward compatibility -- make enabling `_LIBCPP_ENABLE_ASSERTIONS` (which predates hardening modes)
> equivalent to setting the safe mode.
> ifdef _LIBCPP_ENABLE_ASSERTIONS

From LLVM 17, `_LIBCPP_ENABLE_DEBUG_MODE` can be used instead.
See https://libcxx.llvm.org/Hardening.html.
Related to #28476.

This is necessary as the new fixup_chains linker behavior is only valid
when the runtime target is >=11.0.
|
|
Fixes builds with llvm >= 11 in guix by working around the problem. As a bonus,
this is much cleaner and more maintainable than what we had before.
|
|
Use of -stdlib++-isystem gets rid of any system c++ header include paths and
negates the need for this option. In newer versions of clangs the combo
produces a warning.
|
|
See
https://releases.llvm.org/16.0.0/projects/libcxx/docs/UsingLibcxx.html#assertions-mode
for more info.

It was deprecated in LLVM 15, turned into a compile-time error in LLVM 16:
```bash
In file included from /usr/lib/llvm-16/bin/../include/c++/v1/cassert:19:
/usr/lib/llvm-16/bin/../include/c++/v1/__assert:22:5: error: "Defining _LIBCPP_DEBUG is not supported anymore.
Please use _LIBCPP_ENABLE_DEBUG_MODE instead."
^
1 error generated.
```
and has been removed entirely in LLVM 17 (main),
https://github.com/llvm/llvm-project/commit/ff573a42cd1f1d05508f165dc3e645a0ec17edb5.
Building libc++ in debug mode, will also automatically set
`_LIBCPP_ENABLE_DEBUG_MODE` (the new define), so adding it to depends
doesn't seem useful, and would just result in redefinition errors.
I'm wondering if as a followup, we could enable a DEBUG build of libc++
in our MSAN CI job?
Somewhat related to https://github.com/google/oss-fuzz/pull/9828, where
it looks like we'll have to sort out getting a DEBUG build of LLVM.

For some reason the previous syntax worked with clang 15 and below, but
clang 16 requires that the option and value are properly separated.

Pull request description:
On master (4f8b1f8759301d2553183e14f72444a0f1d80725) `{CPP,C,CXX,LD}FLAGS` that are specified in the command line are not propagated to packages:
```

This PR:
- propagates `{CPP,C,CXX,LD}FLAGS` to host packages:
```
$ make --no-print-directory -C depends print-libevent_cxxflags CXXFLAGS=-some-fancy-flag
libevent_cxxflags= -some-fancy-flag
```
- does not propagate `{CPP,C,CXX,LD}FLAGS` to native packages:
```

- actually addresses the https://github.com/bitcoin/bitcoin/pull/23551#issuecomment-973896518

Qt's mkspec references the objcopy tool.
|
|
Use lto.h from clang+llvm not libtapi. The later is older,
and comes bundled with the libtapi repo.
Copy libLTO.so when building with FORCE_USE_SYSTEM_CLANG.
|
|
This improves support for LTO by using gcc wrappers for ar, nm, ranlib,
that correctly setup plugin arguments for LTO.
Other HOSTS are using clang.
|
|
|

|
|
No Qt for now.

Pull request description:
This PR adds lacking definitions of absolute paths to some tools in the depends build system.
This improvement makes possible to keep the `PATH` variable untouched during configuration.

ae9175f6086aa6c177084365c795e78c580eac1d build: add FreeBSD support to depends (fanquake)
Pull request description:
Setup to use the system Clang (11.0.1 as of FreeBSD 13.0).
Doesn't build the Qt package; that requires a few additional changes. The current issue is that FreeBSDs `byacc` seems to have an issue parsing something in libxkbcommon. Work in progress branch here: https://github.com/fanquake/bitcoin/tree/depends_support_freebsd_qt. In any case, I don't think building the Qt libs on FreeBSD is a super high priority (I'd also have no way to test the GUI).

This change made in a way that is compatible with GNU Make versions
older than 4.3.
|
|
This should be sufficient to support building for Apple ARM when
cross-compiling.

f09ed92be132ebcb91b459c87d640a14b4b54336 build: Try posix-specific CXX first for mingw32 host (Hennadii Stepanov)
Pull request description:
On master (1186910b6b7ba7c7e5193c76f33f25825e6cc0b7), when cross-compiling for Windows using our depends build system, we must manually choose the POSIX thread model for the `x86_64-w64-mingw32-g++` compiler.
This PR improves the build system to make this choice automa**g**ically.

GNU Binutils with the exception of the assembler were removed in NDK r23
LTS.

This is required to use std::filesystem on macOS as support for it only
landed in the libc++ dylib shipped with 10.15.
See also: https://developer.apple.com/documentation/xcode-release-notes/xcode-11-release-notes
Clang now supports the C++17 <filesystem> library for iOS 13, macOS 10.15, watchOS 6, and tvOS 13.

Instead of doing the awkward /bin path prepending at config.site
creation time, set darwin_{CC,CXX} in a way that fully determines the
program's path (clang/clang++) similar to how AC_PATH_{TOOL,PROG} would
do.
Also see the added comment block in depends/Makefile for more context on
determining $PATH for our config.site.

clang warns when a command line option is unused, and some of our tests
use Werror, so unfortunately we cannot use this flag to pin our linker
for now. Leaving this commit in for future reference, as it would be
great if there's more granularity to Werror and we can be explicit about
what linker we want to use.
