I am trying to compile LuaJIT 2.0.4 with GCC 4.7.4 on RISC OS. I get > Makefile:235: *** Unsupported target architecture. Stop.
The trouble is that my experience with makefiles is meagre. The makefile provided is huge, and complex (to me). I am not sure whether the make that comes with GCC 4.7.4 is adequate for it. The crunch line is > TARGET_TESTARCH=$(shell $(TARGET_CC) $(TARGET_TCFLAGS) -E lj_arch.h -dM) followed by what is in effect a switch statement. The relevant branch, apparently not taken is > ifneq (,$(findstring LJ_TARGET_ARM ,$(TARGET_TESTARCH))) > TARGET_LJARCH= arm Should GCCSDK's GCC 4.7.4 cope with this? I am aware that there are probably flags that I should have set in the makefile, but I am not sure which or how. A possibility is to make a simpler stripped-down Makefile targetted at the Raspberry Pi2, which does not try to be all things for all platforms. The problem is my lack of expertise. The original LuaJIT (2005) was only for x86 processors. Then came Power-PCs, and after that a bounty appeared for ARM to be catered for. At about the same time (2009) LuaJIT 2 appeared, a complete rewrite, abandoning the standard Lua VM for its own. Development of LuaJIT 1 stopped in 2012, and it never catered for ARM. I think the intended ARM platforms are for Android. It is automatically assumed that cross-compilation from a Linux platform will be the case. But I do not see why a RISC OS version should not be possible. It would be a stunning application to have: high speed, on the OMAP4460 some benchmarks show upto 64-times better results compared to interpreted Lua, with the ease of programming of an interpreted language. Another feature, the ffi-module, does what BBC BASIC's assembler does, which should please ARM assembly-language enthusiasts. -- Gavin Wraith (ga...@wra1th.plus.com) Home page: http://www.wra1th.plus.com/ _______________________________________________ GCCSDK mailing list gcc@gccsdk.riscos.info Bugzilla: http://www.riscos.info/bugzilla/index.cgi List Info: http://www.riscos.info/mailman/listinfo/gcc Main Page: http://www.riscos.info/index.php/GCCSDK
