Alexey Brodkin b4c050e9af gpsd: Fix building with gcc 6.x ... When building C++ parts of gpsd (for example Qt bindings) with gcc 6.x following failure happens, see [1]: ------------------------------>8------------------------------- <command-line>:0:0: warning: "_LARGEFILE_SOURCE" redefined <command-line>:0:0: note: this is the location of the previous definition In file included from clock_gettime.c:10:0: compiler.h: In function 'void memory_barrier()': compiler.h:93:25: error: 'memory_order_seq_cst' was not declared in this scope atomic_thread_fence(memory_order_seq_cst); ^~~~~~~~~~~~~~~~~~~~ compiler.h:93:25: note: suggested alternative: In file included from .../output/host/usr/arc-buildroot-linux-uclibc/include/c++/6.2.1/atomic:41:0, from compiler.h:75, from clock_gettime.c:10: .../output/host/usr/arc-buildroot-linux-uclibc/include/c++/6.2.1/bits/atomic_base.h:62:7: note: 'memory_order_seq_cst' memory_order_seq_cst ^~~~~~~~~~~~~~~~~~~~ In file included from clock_gettime.c:10:0: compiler.h:93:45: error: 'atomic_thread_fence' was not declared in this scope atomic_thread_fence(memory_order_seq_cst); ^ compiler.h:93:45: note: suggested alternative: In file included from .../output/host/usr/arc-buildroot-linux-uclibc/include/c++/6.2.1/atomic:41:0, from compiler.h:75, from clock_gettime.c:10: .../output/host/usr/arc-buildroot-linux-uclibc/include/c++/6.2.1/bits/atomic_base.h:101:3: note: 'std::atomic_thread_fence' atomic_thread_fence(memory_order __m) noexcept ^~~~~~~~~~~~~~~~~~~ scons: *** [qt-clock_gettime.os] Error 1 scons: building terminated because of errors. ------------------------------>8------------------------------- As discussed on gpsd mailng list here [2] the only work-around as of today is to add "-std=gnu++98" to both CFLAGS and CXXFLAGS which we implement here.
