Robin <solence@zoho.eu> has reassigned Bugzilla Automation <bugzilla@FreeBSD.org>'s request for maintainer-feedback to gnome@FreeBSD.org: Bug 221645: www/webkit2-gtk3 build fails on PPC because of exception for PPC https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221645 --- Description --- This build fails with the following error: Source/JavaScriptCore/heap/MachineStackMarker.cpp: In function 'void pthreadSignalHandlerSuspendResume(int, siginfo_t*, void*)': Source/JavaScriptCore/heap/MachineStackMarker.cpp:92:69: error: 'mcontext_t {aka struct __mcontext}' has no member named 'uc_regs' threadData->suspendedMachineContext = *userContext->uc_mcontext.uc_regs; ^ ninja: build stopped: subcommand failed. There is an exception in MachineStackMarker.cpp for PowerPC to use uc_regs, which is not declared on PowerPC, so this does not make much sense: ucontext_t* userContext = static_cast<ucontext_t*>(ucontext); #if CPU(PPC) threadData->suspendedMachineContext = *userContext->uc_mcontext.uc_regs; #else threadData->suspendedMachineContext = userContext->uc_mcontext; #endif Here is the definition of mcontext_t on PowerPC for reference: typedef struct __mcontext { int mc_vers; int mc_flags; #define _MC_FP_VALID 0x01 #define _MC_AV_VALID 0x02 int mc_onstack; /* saved onstack flag */ int mc_len; /* sizeof(__mcontext) */ uint64_t mc_avec[32*2]; /* vector register file */ uint32_t mc_av[2]; register_t mc_frame[42]; uint64_t mc_fpreg[33]; } mcontext_t __aligned(16); Removing the exception allows the build to continue.help
