2020-03-16build: Use pkg-config in BITCOIN_QT_CONFIGURE for all hostsHennadii Stepanov
This change adds to the BITCOIN_QT_CONFIGURE script ability to use pkg-config for MinGW. All of the non-pkg-config paths are removed as needless. If depends is built with DEBUG=1 the configure script fails to pickup Qt: - for macOS host (similar, but not the same as issue 16391) - for Windows host (regression)
2020-03-09build: Fix mingw pkgconfig file and dependency namingHennadii Stepanov
This change adds the correct suffix to debug mode .pc filenames for MinGW and also to the Qt libraries listed in the `Requires` field. The filename adjustment fixes the accidental overwriting of release mode .pc files with the debug mode variant which required the wrong variant of the libraries when `debug_and_release` is active. Note that macOS also supports the `debug_and_release' configuration but may use the regular library names together with DYLD_IMAGE_SUFFIX. Creation of *_debug.pc files is turned off as they're identical to their non-debug counterparts. More info: - QTBUG-4155 - Qt commit a0d8fb4ac3cb7bafdb39f340055eacee4f957513

cb9e88e73a042ff4e1c83289a6f8fa1db03fb093 build: don't embed a build-id when building libdmg-hfsplus (fanquake) Pull request description: There was a [reproducibility issue (IRC logs)](http://www.erisian.com.au/bitcoin-core-dev/log-2020-01-25.html) with the osx `0.19.1rc1` gitian builds. The `build-id` embedded into the `dmg` tool was mismatching. It's possible that differing versions of binutils/ld were the cause. While it was resolved after rebuilding the base gitian image, whether an upstream package issue or fluke, we can remove the possibility of it happening in future by just not embedding a build-id into the `dmg` tool at all. Can close if it's not deemed worth it. You can test this change using the following: ```bash # build libdmg make native_libdmg-hfsplus_built -C depends/ HOST=x86_64-apple-darwin16 -j6 V=1 # master readelf --string-dump .note.gnu.build-id /bitcoin/depends/work/build/x86_64-apple-darwin16/native_libdmg-hfsplus/7ac55ec64c96f7800d9818ce64c79670e7f02b67-3830944ef98/build/dmg/dmg String dump of section '.note.gnu.build-id': [ c] GNU [ 11] CjRa?]?^V8?v?;%n?? # this pr readelf --string-dump .note.gnu.build-id /bitcoin/depends/work/build/x86_64-apple-darwin16/native_libdmg-hfsplus/7ac55ec64c96f7800d9818ce64c79670e7f02b67-a72f53ab110/build/dmg/dmg readelf: Warning: Section '.note.gnu.build-id' was not dumped because it does not exist! ``` ACKs for top commit: laanwj: tested ACK cb9e88e73a042ff4e1c83289a6f8fa1db03fb093 Tree-SHA512: 191eed32ed0a04a908f9c1b22188180b2db2f35bae0281940f0f9da2450c5c6807cd6ff5bbcce7c933a9133387b127c3478f7a39a2918c14f17be19fd9ea19b4

2019-10-23depends: fix boost mac cross build with clang 9+Cory Fields
The ancient "darwin-4.9.1" profile has long been used to match against clang, which prior to version 9, reported 4.9.1 as its version when invoking "clang++ -dumpversion". Presumably this was a historical compatibility quirk related to Apple's switch from gcc to clang. This was "fixed" in clang 9.0, so that -dumpversion reports the real version. Unfortunately that had the side-effect of breaking the (brittle) boost compiler detection. Move to the seemingly more-correct "clang-darwin" profile, which passes the checks and builds correctly. Also switch to using ar rather than libtool for archiving, as it's what the clang-darwin profile expects to be using. Note that because this is using a different profile, some of the final command-line arguments end up changing. The changes look sane at a glance.

Corys PRs (https://github.com/planetbeing/libdmg-hfsplus/pull/7, https://github.com/planetbeing/libdmg-hfsplus/pull/8) have been merged, and the author was active for a little while in 2017/18, so switch back to the upstream [`libdmg-hfsplus`](https://github.com/planetbeing/libdmg-hfsplus) repo. I've added the last of Corys patches into depends. [Switching back to upstream discussion](https://github.com/bitcoin/bitcoin/pull/16392#discussion_r303610767). Top commit has no ACKs.

2019-10-11build: only pass --disable-dependency-tracking to packages that understand itfanquake
By blanket passing --disable-dependency-tracking to all depends packages we end up with some warnings like: configure: WARNING: unrecognized options: --disable-dependency-tracking So instead, only pass it to packages that understand it. Related to https://github.com/bitcoin/bitcoin/issues/16354.

I kept finding myself needing these to debug our build system, since they are innocuous and are very helpful they probably belong in the codebase. Source: John Graham-Cumming https://www.cmcrossroads.com/article/printing-value-makefile-variable

2019-09-30Merge #16927: depends: Refresh ZeroMQ 4.3.1 patchWladimir J. van der Laan
463a1d5244337915de36db36de573eb8782bc430 Refresh ZeroMQ 4.3.1 patch (Nathan Marley) Pull request description: Currently in Alpine Linux (latest, 3.10) in the depends system, one of the ZeroMQ patches won't apply cleanly because the context around the patch has changed and Alpine's `patch` implementation can't handle the diff. Some patch implementations can't handle fuzz / too much divergence from the original code. This PR just tweaks the context code around the patch so that less-sophisticated patch implementations (such as on Alpine Linux) can apply the patch without errors. This partially fixes #16925 ACKs for top commit: fanquake: ACK 463a1d5244337915de36db36de573eb8782bc430 - Tested building zeromq in depends inside an [Alpine container](https://github.com/fanquake/core-review/blob/master/docker/alpine.dockerfile) as well as on macOS.
