我正在尝试使用libusb v1.0.19中的 arm-verifone-linux-gnueabi-gcc 编译器交叉编译Cygwin库,但是在结束时配置调用它会显示此错误:
请求udev支持但未安装libudev。
这是我的配置调用:
./configure CC=arm-verifone-linux-gnueabi-gcc --host=arm-linux
checking operating system... Linux
checking for library containing clock_gettime... -lrt
checking libudev.h usability... no
checking libudev.h presence... no
checking for libudev.h... no
configure: error: "udev support requested but libudev not installed"
configure: WARNING: cache variable lt_cv_path_LD contains a newline
错误清楚地表明libudev在我的设置中不可用,所以我尝试谷歌搜索libudev源码,所以我也可以交叉编译它,但不幸的是我找不到源代码。我在哪里可以找到libudev源或如何解决此错误?
更新: 通过运行此配置行,我能够摆脱“udev”错误:
./configure CC=arm-verifone-linux-gnueabi-gcc --host=arm-linux --disable-udev
但是在运行“make”之后,它会显示:
checking that generated files are newer than configure... done

我该如何解决这个问题?
