使用libld错误构建Android-runtimeTest链接

由于我升级了gcc，我似乎无法编译我的Android 2.1项目

现在有一个链接错误：

out/host/linux-x86/obj/EXECUTABLES/acc_intermediates/main.o: In function `symbolLookup(void*, char const*)':
/home/roeischuster/tdroid/system/core/libacc/tests/main.cpp:41: undefined reference to `dlsym'
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/acc_intermediates/acc] Error 1
make: *** Waiting for unfinished jobs....
out/host/linux-x86/obj/EXECUTABLES/accRuntimeTest_intermediates/runtimeTest.o: In function `symbolLookup':
/home/roeischuster/tdroid/system/core/libacc/tests/runtimeTest.cpp:66: undefined     reference to `dlsym'
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/accRuntimeTest_intermediates/accRuntimeTest] Error 1

我曾尝试将libld添加到system/core/libacc/tests/Androd.mk的本地共享库中，但后来我得到了：

make: *** No rule to make target `out/host/linux-x86/obj/lib/libdl.so', needed by `out/host/linux-x86/obj/EXECUTABLES/accRuntimeTest_intermediates/accRuntimeTest'.  Stop.

我做错了什么？

正如您在错误消息中看到的-

未定义对“dlsym”的引用

，当试图完成编译和链接

main.cpp-->main.o-->main

时，GNU链接器

ld

不知道可以使用

dl

库解析函数

dlsym

。我们可以通过传递参数

--library dl

或

-ldl

来通知

gcc

或

ld

有关

dl

库的信息

对于Android中交叉编译的特殊情况，请再次返回错误消息：

/home/roeischuster/tdroid/system/core/libacc/tests/main.cpp:41: 
undefined reference to `dlsym'

您应该在

~/tdroid/system/core/libacc/tests/Android.mk

上找到一个名为

Android.mk

的文件。要解决编译错误，请在每行

include$（CLEAR\u VARS）

之后添加一行，上面写着

LOCAL\u LDLIBS+=-ldl

。您的

Android.mk

文件现在应该如下所示，如果您在进行更改后再次执行

make

，所有内容都应该编译。干杯：-）
