解决错误 undefined reference to symbol '__cxa_throw_bad_array_new_length@@CXXABI_1.3.8'

在Makefile里，定义CC为"aarch64-linux-gnu-g++ --sysroot=$(MPSOC_ROOTFS)"，编译test.cpp，没有错误。如果使用environment-setup-aarch64-xilinx-linux里的设置，在Makefile里不定义CC，编译test.cpp出现下列错误。

2. 编译器信息

在Makefile里，使用编译器aarch64-linux-gnu-g++。
在environment-setup-aarch64-xilinx-linux里，定义CC为"aarch64-xilinx-linux-gcc --sysroot=$SDKTARGETSYSROOT"，使用编译器aarch64-xilinx-linux-gcc。

  3. Makefile

 

SYSROOT=/xilinxtool/peta/2018.2/zcu106sdk/sysroots/aarch64-xilinx-linux
MPSOC_ROOTFS=/xilinxtool/peta/2018.3/zcu106sdk/sysroots/aarch64-xilinx-linux

CC = aarch64-linux-gnu-g++ --sysroot=$(MPSOC_ROOTFS)

CFLAGS += -g -Wall -O2 -Wall -fpic -fpermissive
CFLAGS += -I ${SYSROOT}/usr/include           -I ${SYSROOT}/usr/include/drm           -I ${SYSROOT}/usr/include/libdrm 
LDFLAGS += -L ${SYSROOT}/usr/lib/ -lpthread -ldl -lrt -Wl,-rpath-link, -Wl,-O1 -Wl,--hash-style=gnu 
LDFLAGS += -ldrm -lm -lEGL

 

4. 解决办法

在environment-setup-aarch64-xilinx-linux里， CC被定义成"aarch64-xilinx-linux-gcc --sysroot=SDKTARGETSYSROOT"。

而Makefile里使用gcc去编译cpp文件，导致错误。Makefile里，定义CC为“aarch64-linux-gnu-g++”，也不符合常规。

在Makefile里使用CXX去编译cpp文件，就没有这个问题，其中CXX被定义成"aarch64-xilinx-linux-g++ --sysroot=SDKTARGETSYSROOT"。

所以关键是使用aarch64-xilinx-linux-g++编译cpp文件。
