为Android构建nanomsg

Question

我有来自here的nanomsg和Android.mk。我尝试用Android NDK为Android构建它。我犯了一个错误：

问题出在哪里？我希望有人能帮上忙。

Answer 1

在您的Android.mk文件中，将您的

使用以下几行代码进行LOCAL_CFLAGS

LOCAL_CFLAGS :=  \
    -DNN_HAVE_STDINT \
    -DNN_HAVE_CLOCK_MONOTONIC \
    -DNN_HAVE_PIPE \
    -DNN_HAVE_SOCKETPAIR \
    -DNN_HAVE_SEMAPHORE \
    -DNN_HAVE_POLL \
    -DNN_USE_POLL \
    -DNN_USE_LITERAL_IFADDR \
    -DNN_HAVE_MSG_CONTROL

这两条线也是。

LOCAL_COPY_HEADERS_TO := nanomsg
LOCAL_COPY_HEADERS := nn.h bus.h reqrep.h pipeline.h pair.h survey.h pubsub.h
