链接V8时的未定义参考 [英] undefined reference when linking V8

问题描述

pre> #includev8.h

int main（）
{
v8 :: HandleScope handle_scope;

return 0;
}


编译行：g ++ -I / home / lterje / git / tengine / Externals / v8 / include /home/lterje/git/tengine/Externals/v8/out/ia32.release/obj.target/tools/gyp/libv8_snapshot.a test.cpp -o test -lpthread

我得到的错误：

  /tmp/ccHYtJuE.o： 
 test.cpp :(。text + 0x11）：未定义的引用`v8 :: HandleScope :: HandleScope（）'
 test.cpp :(。 ：HandleScope ::〜HandleScope（）'
 collect2：error：ld返回1退出状态
  

基础，快照和快照库文件之间的区别究竟是什么？我试过链接每个人，但没有一个工作：/

解决方案

可怜的英语。
我只是将.a文件链接到我自己的项目。
由于libv8_snapshot.a的依赖关系没有给出，因此有ld错误。

这是我的编译语句：

g ++ -o xxxxx -I〜v8 / out / native / obj.target / tools / gyp / libv8_ {base.native，snapshot} .a〜v8 / out / native / obj.target / third_party /icu/libicu{data,i18n,snapshot}.a〜v8 / out / native / obj.target / icudata / third_party / icu / linux / icudt46_dat.o -lrt -lpthread

我认为libv8_base.native.a libv8_snapshot.a是依赖于icu和icudt46文件，有一些关于unix clock_time的函数是依赖于rt，所以添加-lrt

希望对你有帮助〜
作为中文，对不起我的英语。

I'm strugling to compile a really small example with V8..

cpp program is this:

#include "v8.h"

int main()
{
     v8::HandleScope handle_scope;

     return 0;
}

Compile line: g++ -I/home/lterje/git/tengine/Externals/v8/include /home/lterje/git/tengine/Externals/v8/out/ia32.release/obj.target/tools/gyp/libv8_snapshot.a test.cpp -o test -lpthread

Error I'm getting:

/tmp/ccHYtJuE.o: In function `main':
test.cpp:(.text+0x11): undefined reference to `v8::HandleScope::HandleScope()'
test.cpp:(.text+0x22): undefined reference to `v8::HandleScope::~HandleScope()'
collect2: error: ld returned 1 exit status

What exactly is the difference between the base, snapshot and no snapshot library files? I've tried linking with each of them, but none of them works :/

解决方案

first I have to say sorry for my poor english. I have just link the .a file to my own project. There's ld error because of the dependencies of the libv8_snapshot.a is not been given.

This is my compile statement:

g++ -o xxxxx -I ~v8/out/native/obj.target/tools/gyp/libv8_{base.native,snapshot}.a ~v8/out/native/obj.target/third_party/icu/libicu{data,i18n,snapshot}.a ~v8/out/native/obj.target/icudata/third_party/icu/linux/icudt46_dat.o -lrt -lpthread

I think that the libv8_base.native.a libv8_snapshot.a is dependend on icu and icudt46 files and thereis some functions about unix clock_time is dependend on "rt", so add "-lrt"

Hope helpful for you all~ As a Chinese,sorry for my english.
