Hello all, I am a newbie though I have used CMake a bit for a few projects. Now, I am trying to use CMake for cross-compiling on my Linux desktop for an embedded system (ARM DS-5 based).
Right now, the needs are simple - I need to specify the compiler and linker with flags for both. However, I can't figure out why the linking step doesn't work. The "armlink" does get specified but Make is invoking it without any parameters, i.e., without any object files to link and produce the output .elf file. I am looking to keep it simple and hopefully this is not too involved. Any advice appreciated. My system has cmake version 2.8.7 and I invoke as: $ cd build $ cmake .. $ make VERBOSE=1 I can't seem to figure out where and how do I tell that the output will be blinky.elf. e.g., If I try on command-line by myself it is: $ armlink --cpu=Cortex-M3 --map --ro-base=0x0 --rw-base=0x0008000 --first='boot.o(RESET)' --datacompressor=off CMakeFiles/blinky.dir/blinky.c.o -o blinky.elf but the makefile is invoking as only: $ armlink My current CMakeLists and output is given below.
