为ARMHF编译Crypto ++时链接错误 [英] Linking error when compiling Crypto++ for ARMHF
问题描述
我正在尝试编译crypto ++库来运行armhf架构。我遵循此答案中提供的方法。我调整了 setenv-embed.sh 以匹配我的系统配置。运行的输出。 ./setenv-embed.sh 是
I'm trying to compile the crypto++ library to run for the armhf architecture. I'm following the method provided in this answer. I tweaked the setenv-embed.sh to match my system's configuration. The output of running . ./setenv-embed.sh is

ARM_EMBEDDED_SYSROOT: /usr/arm-linux-gnueabihf
，表示已找到正确的编译器。但是，当我使用 make 构建库时，遇到以下错误
which indicates that the correct compilers have been found. However, when I build the library using make I run into the following error
/usr/lib/gcc-cross/arm-linux-gnueabihf/4.8/../../../../arm-linux-gnueabihf/bin/ld: cannot find /usr/arm-linux-gnueabihf/lib/libc.so.6 inside /usr/arm-linux-gnueabihf
/usr/lib/gcc-cross/arm-linux-gnueabihf/4.8/../../../../arm-linux-gnueabihf/bin/ld: cannot find /usr/arm-linux-gnueabihf/lib/libc_nonshared.a inside /usr/arm-linux-gnueabihf

但是当我打开位置 / usr / arm-linux-gnueabihf / lib 我可以找到上面提到的所有三个错误文件ie libc.so.6 ， libc_nonshared.a 和 ld-linux-armhf.so.3
But when I open the location /usr/arm-linux-gnueabihf/lib I can find all the three error files mentioned above ie libc.so.6, libc_nonshared.a and ld-linux-armhf.so.3
我正在为Beaglebone编译库，如果那个hel ps。
I'm trying to compile the library for Beaglebone, if that helps.

推荐答案
问题很简单。它位于 - sysroot 选项中。该选项的值为 / usr / arm-linux-gnueabihf / ，由链接器使用，生成的库文件夹将成为
/ usr / arm-linux-gnueabihf / usr / arm-linux-gnueabihf / lib /
The problem is simple. It is in the --sysroot option. The value of this option is /usr/arm-linux-gnueabihf/ and it is used by the linker and the resulting library folder becomes
/usr/arm-linux-gnueabihf/usr/arm-linux-gnueabihf/lib/
我删除了 - sysroot 选项从第68行文件GNUmakefile-cross和所有编译和链接确定。
I removed the --sysroot option from line 68 in the file GNUmakefile-cross and everything compiled and linked OK.
但是，我无法运行我的BeagleBone黑色的例子，因为一些共享库版本不匹配。但这对我来说不是一个真正的问题，因为在我的应用程序中，我将静态链接crypto ++，而不是动态链接。
However, I couldn't run the example on my BeagleBone Black because of mismatch of some shared libraries versions. But this wasn't a real problem for me, because in my application I link crypto++ statically, not dynamically.
