C++ 交叉编译Webots控制器
我正在尝试使用MinGW从Linux到Windows交叉编译Webots()的机器人控制器(.exe) Webots提供了一个所有平台通用的文件,该文件为编译准备了构建环境(必要的依赖项): 我当前的makefile,其中我根据MinGW和我的webots安装设置了几个变量:C++ 交叉编译Webots控制器,c++,makefile,mingw,cross-compiling,webots,C++,Makefile,Mingw,Cross Compiling,Webots,我正在尝试使用MinGW从Linux到Windows交叉编译Webots()的机器人控制器(.exe) Webots提供了一个所有平台通用的文件,该文件为编译准备了构建环境(必要的依赖项): 我当前的makefile,其中我根据MinGW和我的webots安装设置了几个变量: WEBOTS_HOME = /usr/share/webots/resources/windows_home #WEBOTS_HOME = /usr/share/webots RESOURCES_PATH = $(WEB

另外,我已经在我的Windows设备上安装了Webots,并将安装文件夹复制到Linux设备上的安装文件夹中,这样我就可以访问预编译的Windows库
问题是当链接器尝试查找两个库时(-lccontroller
和-lCppController
,它们附加在Makefile.include
)中:
从我收集的资料来看,这个问题通常是在尝试将32位库链接到64位二进制文件时引起的(反之亦然),但我的makefile或makefile.include上没有-m32
或-m64
标志。我的OSs都是64位的,所以我认为库的类型应该没有任何问题
我尝试过使用Webots的本机linux安装文件夹,但遇到了类似的问题:

/usr/share/webots/resources/Makefile.include:529: recipe for target 'build/release/darwin_socket.exe' failed
make: *** [build/release/darwin_socket.exe] Error 1
这很奇怪,因为libController.so
和libcppccontroller.so
都存在于/usr/share/webots/lib/
中
那么我到底错过了什么呢?一个有趣的问题。我和Webots合作多年,但从未尝试过。一点也不确定,但不会,因为您应该使用libController.dll文件(windows one)而不是libController.so(linux one)。
