Question

我使用以下脚本来构建C ++库。对于i386架构，一切正常，但对于arm64，我收到一条错误消息。

错误：

make[1]: *** [base/low/cl_low_div.lo] Error 1
make: *** [install-recursive] Error 1

剧本：

   arr[${#arr[@]}]=$sdk

make clean

make install
}

findLatestSDKVersion iPhoneOS

buildit arm64 iPhoneOS

lipo -create ./output/arm64/lib/libcln.a -output libcln.a

其中一个错误（都是相似的）：

base/low/cl_low_div.cc:210:8: error: declaration of 'divu_64_rest' in global
  scope conflicts with declaration with C language linkage
  uint64 divu_64_rest;
         ^
./base/cl_low.h:982:21: note: declared with C language linkage here
  extern "C" uint64 divu_64_rest;                         // -> Rest r

我找不到有关它与构建库的架构之间的连接的信息。

提前致谢。

请在您的问题中发布错误，而不是在其他地方发布，尤其不是那些不允许纯文本复制/粘贴的地方。选择完整输出的相关部分并仅发布，而不是大量无用的内容。

您的问题是在头文件cl_low.h中声明了一个如下变量：

extern "C" uint64 divu_64_rest;

但在源文件cl_low_div.cc中，您将其定义为：

uint64 divu_64_rest;

那些不一样。在声明变量和定义变量时，必须同时具有extern "C"（或不）extensions.conf [test] exten => *300,1,NoOp(login/logout) ${DB(Queue/PersistentMembers/empfang)} ${REGEX("PJSIP/1001"),${DB(/Queue/PersistentMembers/empfang)}} same => n,GotoIf(${REGEX("PJSIP/1001",${DB(Queue/PersistentMembers/empfang)})}?*300-logout,1:*300-login,1) same => n,Hangup exten => *300-logout,1,NoOp(1001 exists, logout) same => n,RemoveQueueMember(empfang,PJSIP/1001) same => n,Playback(beep) same => n,Hangup() exten => *300-login,1,NoOp(1001 doesn't exists, login) same => n,AddQueueMember(empfang,PJSIP/1001) same => n,Playback(beep) same => n,Hangup()。你所有的错误似乎都很相似。
