bre*_*101 8 valgrind arm embedded-linux cortex-a8
我在ARM CortexA8的实际程序中找到了linux以下问题:
´*** glibc detected *** ./PRUssExternal: double free or corruption (top): 0x00024fe8 ***´
我正在网上搜索它,我发现管理这个问题最有用的程序是Valgrind.
然后我尝试在交叉编译中编译到我的系统,在配置中使用以下选项.我正在使用Valgrind 3.8.1
@ -virtual-machine:〜/ valgrind-3.8.1 $ CC = arm-cortexa8-linux-gnueabi-gcc CFLAGS =" - pipe -Os -mtune = cortex-a8 -march = armv7-a -mabi = aapcs-linux -msoft-float -I/opt/OSELAS.Toolchain-2011.11.3/arm-cortexa8-linux-gnueabi/gcc-4.6.2-glibc-2.14.1-binutils-2.21.1a-kernel-2.6.39-sanitez/sysroot-arm-cortexa8-linux-gnueabi/usr/include"LDFLAGS =" - L/opt/OSELAS.Toolchain-2011.11.3/arm-cortexa8-linux-gnueabi/gcc-4.6.2-glibc-2.14.1 -binutils-2.21.1a-kernel-2.6.39-sanitez/sysroot-arm-cortexa8-linux-gnueabi/usr/lib"./ configure -prefix =/opt/valgrid -host = arm-cortexa8-linux-gnueabi - target = arm-none-linux-gnueabi -build = x86_64-ubuntu-linux
这个配置的输出是:

在这个输出的最后一行,My Issue出现了,虽然我查找了一些信息,而Cortexa8却是支持的平台之一.
出于这个原因,我的问题是我的电路板是否不受支持,因为我使用的库不兼容,或者可能是其他原因.或者另一方面,我可以毫无畏惧地编译valgrind并跳过这个检查.
谢谢你的时间
