Let configure include `sys/if_tun.h` when testing for `netinet/if_ether.h` to detect the Kernel/libc header conflict on musl. After this patch, configure will correctly detect `netinet/if_ether.h` as unusable and the subsequent compilation will not attempt to use it. Fixes the following compatibility error: In file included from .../staging_dir/toolchain-mips_mips32_gcc-4.8-linaro_musl-1.1.9/include/linux/if_tun.h:20:0, from linux/device.c:24: .../staging_dir/toolchain-mips_mips32_gcc-4.8-linaro_musl-1.1.9/include/linux/if_ether.h:137:8: error: redefinition of 'struct ethhdr' struct ethhdr { ^ In file included from .../staging_dir/toolchain-mips_mips32_gcc-4.8-linaro_musl-1.1.9/include/net/ethernet.h:10:0, from linux/../have.h:180, from linux/../system.h:26, from linux/device.c:21: .../staging_dir/toolchain-mips_mips32_gcc-4.8-linaro_musl-1.1.9/include/netinet/if_ether.h:96:8: note: originally defined here struct ethhdr { ^ make[5]: *** [linux/device.o] Error 1 Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> |
