[Buildroot] luaposix not working with luajit/lua5.1

[Arnout Vandecappelle]

 Hi Francois,

 Three years ago you submitted a patch that was supposed to fix luaposix by
adding the bitop module. However, with this defconfig:

BR2_x86_64=y
BR2_x86_core2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-x86-64-core2-full-2017.02-rc1-2-g133c5ac.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_5=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_4=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_INET_RPC=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_LUA=y
BR2_PACKAGE_LUA_5_1=y
BR2_PACKAGE_LUAPOSIX=y

 I get:
# chroot output/target /usr/bin/lua -e 'require "posix"'

        (command line):1: in main chunk
        [C]: at 0x00402068

 Am I missing something?


 I've worked around this by using the bit32 module instead of the bitop module.
I can submit this patch but I first wanted to check if I just did something wrong.

 Regards,
 Arnout
