ARM64 relocation error due to default linker flags #28

Closed opatry closed 9 years ago

opatry commented 9 years ago

Hi,

it seems that the default linker flags breaks the ARM 64 build available since NDK r10 (cf. PR 23).

set( CMAKE_EXE_LINKER_FLAGS    "-Wl,-z,nocopyreloc"      CACHE STRING "executable linker flags" )

should be replaced with 

set( CMAKE_EXE_LINKER_FLAGS    ""      CACHE STRING "executable linker flags" )

It fixes the relocation/link issue on ARM64 and had no incidence on other architectures. Maybe it should be defined according to current architecture and disabled only for ARM64?

Using the master branch instead of the mentioned PR 23, everything goes well despite the -Wl,-z,nocopyreloc linker flag.
