I'm not really familiar with VxWorks but I imagine this should be OK. If the required ABI for libraries has changed it ought to be mentioned in the documentation. >I don't think that this is really building a cross compiler >as my host and target are sharing the same instruction set, >but different OS's. Technically, it is still a cross compiler and you still have to configure it as such. >I wish to evaluate the code generation improvement over the >2.7.9-970819 compiler. Would I be more wise to get an egcs >version? No; gcc 2.95.1 supplants the egcs-1.x releases. >The compiler on the Netwinder is 2.8.1, but I am quite sure >it produces elf output. Yes. The NetWinder ships with a modified version of gcc 2.8.1 to which ARM/ ELF support was added. >If I wish to build a cross compiler for NT with an VxWorks >ARM target would it be better to use an x86 linux or the ARM >linux (or no different)? I don't really understand what you're getting at here. p. ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
