I think maybe this compile error from compiler version. Please let me know recommend or require Sourcery CodeBench compiler version.

Hello,

I am using 4.7.3 version, and did not experience this issue, can you try that one and report back?

Accepted Answer

Hello Martin, I find this issue point. mbed-SDK python script, call to "arm-none-eabi-foo", but Sourcery CodeBench name is arm-none-linux-gnueabi-foo or arm-none-linux-gnueabi/bin/gcc. Therefore, I make to hard link. ln -sf arm-none-linux-gnueabi-foo arm-none-eabi-foo Build.py is call of only arm-none-eabi-foo. not arm-none-linux-gnueabi-foo.

please see following. workspace_tools/toolchains/gcc.py

        main_cc = join(tool_path, "arm-none-eabi-gcc")
        main_cppc = join(tool_path, "arm-none-eabi-g++")
        self.asm = [main_cc, "-x", "assembler-with-cpp"] + common_flags
        if not "analyze" in self.options:
            self.cc  = [main_cc, "-std=gnu99"] + common_flags
            self.cppc =[main_cppc, "-std=gnu++98"] + common_flags
        else:
            self.cc  = [join(GOANNA_PATH, "goannacc"), "--with-cc=" + main_cc.replace('\\', '/'), "-std=gnu99", "--dialect=gnu", '--output-format="%s"' % self.GOANNA_FORMAT] + common_flags
            self.cppc= [join(GOANNA_PATH, "goannac++"), "--with-cxx=" + main_cppc.replace('\\', '/'), "-std=gnu++98", "--dialect=gnu", '--output-format="%s"' % self.GOANNA_FORMAT] + common_flags
        
        self.ld = [join(tool_path, "arm-none-eabi-gcc"), "-Wl,--gc-sections", "-Wl,--wrap,main"] + self.cpu
        self.sys_libs = ["stdc++", "supc++", "m", "c", "gcc"]
        
        self.ar = join(tool_path, "arm-none-eabi-ar")
        self.elf2bin = join(tool_path, "arm-none-eabi-objcopy")


class GCC_CS(GCC):
    def __init__(self, target, options=None, notify=None, macros=None):
        GCC.__init__(self, target, options, notify, macros, GCC_CS_PATH)

Thank you for your pick-up and answer for my question. Regards, Kazu,
