I'm just now working on converting some of my SAM7X code over to C++, taking cues from the popular "Building Bare Metal Systems" series of articles. I have the C++ runtime in decent shape and most things seem to be working as expected. My problem is that the libc.a that my project links against is /usr/local/arm/bin/../lib/gcc/arm-elf/4.2.2/../../../../arm-elf/lib/inte rwork/libc.a and that version of libc.a does not have init.o included. The function I'm ultimately trying to get at is __libc_init_array to initialize static constructors. The example projects from the Bare Metal series show the equivalent of /usr/local/arm/bin/../lib/gcc/arm-elf/4.2.2/../../../../arm-elf/lib/libc .a being linked in, which in my toolchain does include init.o and the symbol for __libc_init_array, but I can't quite figure out how to specify that. My project is based on the FreeRTOS, originally from the SAM7X256 lwIP demo which has a makefile very similar to Martin's. I'm using the toolchain compiled by Darrik Spaude for OS X intel - the latest version he has there is 4.2.2. Should the interwork version of libc.a include this? Is some other aspect of my configuration screwy? Thanks for any tips!
Hi, Did any one solve this problem ? I am facing the same problem when porting the "Building Bare Metal Systems" C++ example to SAM7X ARM.
