D.gnu - Porting gdc to a new target (Nios2) any guides out there?
- John Carter (7/7) Jul 22 2014 So for various reasons I see potential to use a gdc on an Altera
- Timo Sintonen (13/20) Jul 22 2014 I do not know this system but should be possible.
- Iain Buclaw via D.gnu (8/22) Jul 22 2014 exists....
- Timo Sintonen (11/19) Jul 22 2014 The tricky part in arm build is libgcc. Is this processor type
So for various reasons I see potential to use a gdc on an Altera FPGA with a nios2 softcore running embedded linux. Given gdc on linux exists, gdc arm port exists, gcc nios2 back end exists.... Leaves me wondering... how hard could it be to get gdc targetting Nios2? Any "this is how to do these things" type guides out there?

Maybe this is the starting point: http://wiki.dlang.org/GDC/Installation At the end of the page there is a link to cross compiler page. In that page there is 4 different ways people have used. First forget D and try to build a C only toolset. If this works then build c++. If this works, then build D without library. If this works, then make your own runtime library, see Mikes work here: https://github.com/JinShil/D_Runtime_ARM_Cortex-M_study/wiki/1.0-Introduction or port an existing library like my minlibd: https://bitbucket.org/timosi/minlibd

If this works thenbuild c++ I'd skip step one and just go straight to building C++ first. Given that gcc is no longer written in C. Iain

Is this processor type mentioned and enabled by default in t-arm-elf? Is the library built with correct flags and is gcc picking the right one? C++ build also needs target libc and possibly the just built target libgcc while C only does not need any target library If something is not working C++ build may always fail. This is why I recommend to build C first to see if it can produce a working executable. If libraries are not working the C++ configure will never succeed.First forget D and try to build a C only toolset.
