当我尝试vrpn 7.33在 Mac 上编译时出现以下错误。它说这libusb是为不同的架构编译的，而不是vrpn正在编译的：

Linking CXX executable client_and_server
ld: warning: ignoring file /usr/local/lib/libusb-1.0.dylib, file was built for i386 which is not the architecture being linked (x86_64): /usr/local/lib/libusb-1.0.dylib

但是，当我重新编译libusb将架构更改为时，x86_64我开始收到以下错误：

Linking CXX executable client_and_server

注意链接器现在是如何搜索原始i386架构的。

为什么vrpn在这两种情况下都抱怨？

vrpn正在同时为多个架构编译。这就是为什么libusb单一架构的编译不起作用的原因。

libusb解决方案是使用以下命令序列同时编译两个架构：

./configure
make CFLAGS="-arch x86_64 -arch i386" LDFLAGS="-arch x86_64 -arch i386"
sudo make install
