C++ G++；ARM交叉编译：未定义的引用

我正在尝试用arm-none-eabi-g++编译代码。 但是，它首先失败，并显示以下错误消息

/usr/lib/gcc/arm-none-eabi/4.8.2/../../../arm-none-eabi/bin/ld: cannot find -lstdc++

为了解决这个问题，我确保可以链接libstdc++.a。一旦我修复了它，它就失败了，出现以下错误：

/usr/lib/gcc/arm-none-eabi/4.8.2//libgcc.a(unwind-arm.o): In function `get_eit_entry':

以下是它失败的实际步骤：

arm-none-eabi-g++ -static -nostartfiles -ffreestanding -T ld_script -Wl,-O1,-Map=list.txt  ftl.o sata_identify.o sata_cmd.o sata_isr.o sata_main.o sata_table.o initialize.o mem_util.o flash.o flash_wrapper.o misc.o uart.o init.o -o firmware.elf -L"/usr/lib/gcc/arm-none-eabi/4.8.2/" -lgcc

有人能提出解决办法吗？此外，如果我使用arm-none-eabi-gcc而不是arm-none-eabi-g++，这也可以很好地解决问题。

编译器生成的异常处理代码导致了问题，它依赖于运行时组件，而这些组件在您的构建中并不存在

关闭编译器代码生成中的异常处理。

粗略猜测

-fno异常

？谢谢@matstpeterson！这确实消除了那些错误！谢谢。

-fno异常的作用是什么？我在网上找不到任何东西。谢谢你！此外，这会有任何运行时的副作用吗？我计划在ARM7TDMI控制器上运行代码。不要尝试抛出异常-会发生一些不好的事情，我不确定会发生什么（但希望所有代码都使用此标志编译，如果您尝试，我很确定会出现错误）
