Description
src/angle/src/config.pri
gcc {
QMAKE_CFLAGS_WARN_ON += -Wno-unknown-pragmas -Wno-comment -Wno-missing-field-initializers \
-Wno-switch -Wno-unused-parameter -Wno-write-strings -Wno-sign-compare -Wno-missing-braces \

QMAKE_CXXFLAGS_WARN_ON = $$QMAKE_CFLAGS_WARN_ON -Wno-reorder -Wno-conversion-null -Wno-delete-non-virtual-dtor
sse2: QMAKE_CXXFLAGS += -march=native
}
That -march=native is incorrect and it causes GCC to generate code that cannot be sent to another machine. Since sse2 is enabled for all x86-64 builds, as a consequence this makes the ANGLE libraries not portable at all.
That line was added with commit a6a12d8c0fc918972c15268f749ecc7c90b95d6c (ANGLE: upgrade to 2.1~07d49ef5350a) and it must go.
