我在我的实际程序中发现了以下问题:
´*** glibc detected *** ./PRUssExternal: double free or corruption (top): 0x00024fe8 ***´
我在网上搜索，我发现最有用的程序来管理这个问题是Valgrind。
如何使用gdb跟踪c++中的double free或corruption错误
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 .3 = 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/包括"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前缀=/opt/valgrid主机= arm-cortexa8-linux-gnueabi—target = arm-none-linux-gnueabi构建= x86_64-ubuntu-linux

在这个输出的最后一行，出现了My Issue，尽管我查找了一些信息，并且cortex是受支持的平台之一。
valgrind on ARM9?
因此，我的问题是我的板是否不受支持，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。
感谢您的宝贵时间
对

您应该编辑配置文件。找到一行"armv7*"并将其更改为"arm*"-这就足够了。
