Question

此刻，我尝试为Raspberry交叉编译一个应用程序，该程序具有czmq库作为依赖项。

我的方法：

在Raspberry pi（https://github.com/zeromq/czmq）上安装czmq库
重新同步我的本地sysroot文件夹（在我的主机上）（/usr/; /lib/）
启动我的交叉编译器：

arm-linux-gnueabihf-gcc --sysroot=/home/alexander/tmp/CMake_Raspi/rootfs -g 
-Wall -fmessage-length=0 -ggdb -Iinclude src/functions.c src/Trainstation_Sequenzer.c 
-o bin/trainstationsequencer -lczmq -lzmq -pthread

但是有很多错误

如果我使用buildroot在主机上启动编译，则没有错误，并且该应用程序在我的Raspberry上运行
如果我在主机上开始编译（仅使用gcc =>无交叉编译），则没有错误，并且该应用程序在桌面PC上运行
如果我在Raspberry（使用gcc）上开始编译，则没有错误，并且应用程序在Raspberry上运行

你知道我的错是什么吗？
