commit ec0803510289fcb15d8b4f8699169ac35f842bfe Author: Paolo Bonzini <pbonzini@xxxxxxxxxx> AuthorDate: Wed Aug 11 12:05:50 2021 +0200 Commit: Michael Roth <michael.roth@xxxxxxx> CommitDate: Tue Dec 14 12:49:09 2021 -0600 plugins: do not limit exported symbols if modules are active On Mac --enable-modules and --enable-plugins are currently incompatible, because the Apple -Wl,-exported_symbols_list command line options prevents the export of any symbols needed by the modules. On x86 -Wl,--dynamic-list does not have this effect, but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides it. On Apple there is no -Wl,--export-dynamic, because it is the default, and thus no override. Either way, when modules are active there is no reason to include the plugin_ldflags. While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is specified but --enable-modules is not; this way, the GNU and Apple configurations are more similar.
