From 94a861512afaa8a2cd330b436e7a380899759f93 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= <bjorn@erlang.org> Date: Tue, 19 Sep 2023 17:41:25 +0200 Subject: [PATCH] Fix link problem with Xcode 15 The dynamic libraries for the `wx` application would fail to build with the new linker in Xcode 15 for macOS. One workaround is to force the old linker to be used, but that will stop working when the the old linker is eventually retired. It turns out that `wx` uses a very old way to create dynamic libraries. Essentially it asks the linker to accept that there are references to undefined symbols, trusting that they will be defined when the dynamic library is loaded. That is done using the following options: -bundle -flat_namespace -undefined suppress The option `-undefined suppress` is deprecated by the new linker and it will consider undefined symbols to be an error. A more modern approaph to creating dynamic libraries is to use the the `-bundle_loader` option to point out an executable that can be used to satisfy references to undefined symbols: -bundle -bundle_loader $ERL_TOP/bin/aarch64-apple-darwin22.6.0/beam.smp Care must be taken not to include the `-bundler_loader` option in `configure` tests that test linking, because the `beam.smp` executable has not been built at that time and the linker in older Xcode releases will complain if the executable does not exist. It seems that Xcode 15 will check that the executable exists only if there are references to undefined symbols. While at it, update the ancient build instructions for wxWidgets. --- HOWTO/INSTALL-WIN32.md | 14 +++++------ HOWTO/INSTALL.md | 51 ++++++++++++++++++++++------------------ lib/wx/c_src/Makefile.in | 2 +- lib/wx/configure | 15 ++++++++---- lib/wx/configure.ac | 15 ++++++++---- 5 files changed, 56 insertions(+), 41 deletions(-) diff --git a/HOWTO/INSTALL-WIN32.md b/HOWTO/INSTALL-WIN32.md index bd8387aaae..f0f254fff6 100644 --- a/HOWTO/INSTALL-WIN32.md +++ b/HOWTO/INSTALL-WIN32.md @@ -61,8 +61,8 @@ This is the short story though, for the experienced and impatient: * Get, build and install OpenSSL v1.1.1d or later (up to 1.1.1d tried & working) with static libs. - * Get, build and install wxWidgets-3.1.3 or later (up to 3.1.3 - tried & working) with static libs. + * Get, build and install wxWidgets-3.2.2.1 or later (up to that + version tried & working) with static libs. * Get the Erlang source distribution (from <http://www.erlang.org/download.html>) and unpack with `tar` @@ -152,20 +152,20 @@ the different tools: * wxWidgets (optional) You need this to build wx and use gui's in debugger and observer. - We recommend v3.1.4 or later. - Unpack into `c:/opt/local64/pgm/wxWidgets-3.1.4` + We recommend v3.2.2.1 or later. + Unpack into `c:/opt/local64/pgm/wxWidgets-3.2.2.1` - If the `wxUSE_POSTSCRIPT` isn't enabled in `c:/opt/local64/pgm/wxWidgets-3.1.4/include/wx/msw/setup.h`, + If the `wxUSE_POSTSCRIPT` isn't enabled in `c:/opt/local64/pgm/wxWidgets-3.2.2.1/include/wx/msw/setup.h`, enable it.
