Bug 270963 – [GTK] [2.42.5] SharedContextMutex.cpp: error: inlining failed in call to ‘always_inline’

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKitGTK

[Alberto Garcia]

Both WebKitGTK and WPE WebKit 2.42.5 have recently stopped building in Debian unstable:

                           ----------------------------------------
/<<PKGBUILDDIR>>/Source/ThirdParty/ANGLE/src/libANGLE/SharedContextMutex.cpp:219:41: error: inlining failed in call to ‘always_inline’ ‘egl::SharedContextMutex<Mutex>* egl::SharedContextMutex<Mutex>::doTryLock() [with Mutex = std::mutex]’: recursive inlining
  219 | ANGLE_INLINE SharedContextMutex<Mutex> *SharedContextMutex<Mutex>::doTryLock()
      |                                         ^~~~~~~~~~~~~~~~~~~~~~~~~

/<<PKGBUILDDIR>>/Source/ThirdParty/ANGLE/src/libANGLE/SharedContextMutex.cpp:241:41: error: inlining failed in call to ‘always_inline’ ‘egl::SharedContextMutex<Mutex>* egl::SharedContextMutex<Mutex>::doLock() [with Mutex = std::mutex]’: recursive inlining
  241 | ANGLE_INLINE SharedContextMutex<Mutex> *SharedContextMutex<Mutex>::doLock()
      |                                         ^~~~~~~~~~~~~~~~~~~~~~~~~
                           ----------------------------------------

This is due to the ANGLE_INLINE macro in Source/ThirdParty/ANGLE/src/common/angleutils.h:

   #if defined(NDEBUG) && ANGLE_HAS_ATTRIBUTE_ALWAYS_INLINE
   #    define ANGLE_INLINE inline __attribute__((always_inline))
   #elif defined(NDEBUG) && ANGLE_HAS___FORCEINLINE
   #    define ANGLE_INLINE __forceinline
   #else
   #    define ANGLE_INLINE inline
   #endif

I'm building WebKit with NDEBUG so ANGLE_INLINE is 'inline __attribute__((always_inline))'

If I stop using NDEBUG or otherwise force ANGLE_INLINE to simply be 'inline' then this builds fine.

Never mind, this was caused because I was accidentally using -Werror=implicit-function-declaration for C++ files.

Closing as invalid.
