编译问题？关于ACE的

chunyv

环境

# uname -a
FreeBSD  7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24 10:35:36 UTC 2008     root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

Target: amd64-undermydesk-freebsd

Thread model: posix
gcc version 4.2.1 20070719  [FreeBSD]

用/usr/posts/devel/ace安装的

# pkg_info|grep ace
ace-5.5.2_2         The Adaptive Communication Environment for C++

程序源码

#include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include "ace/ACE.h" #include "ace/OS.h" #include "ace/Message_Block.h" int main(int argc , char * argv[]) {     ACE_Message_Block *head = new ACE_Message_Block(BUFSIZ);     ACE_Message_Block *mblk = head;          for(;;)     {         ssize_t nbytes = ACE::read_n(ACE_STDIN , mblk->wr_ptr(),mblk->size());         if(nbytes <= 0)                     {             printf("%s:%d\n" , __FILE__ , __LINE__);             break;         }                  mblk->wr_ptr(nbytes);         printf("str = %s\n" , mblk->rd_ptr());                  mblk->cont(new ACE_Message_Block(BUFSIZ) );         mblk = mblk->cont();     }      //    ACE::write_n(ACE_STDOUT , head );          for(mblk = head ; mblk != 0; mblk=mblk->cont())     {         ACE::write_n(ACE_STDOUT , mblk->rd_ptr() , mblk->length() );     }          head->release();              return EXIT_SUCCESS; }

编译命令

g++ -o list list.cpp -I /usr/local/include/ -L /usr/local/lib/libACE.a

出错消息

我试过同样的代码和编译命令在Cent OS4.5上用g++ -o list list.cpp   -l ACE 就可以了

gvim

Cent OS4.5 的g++版本是多少？
没用过ace，/usr/local/lib/libACE.a 有 /usr/local/lib/libACE.so 吗？

chunyv

centos 的gcc是 3.4.6

两个系统的ace的头文件都在/usr/local/include/ace下面
库文件都在 /usr/local/lib/

-_-; 我的意思是：如果有.so，你试试 -l....ACE.so。而不是问你有没有这个东西。。。所以用不着把所有的列出来，我没必要知道
或者-L/usr/local/lib -lACE

gvim

g++ -o list list.cpp -I /usr/local/include/ -L /usr/local/lib/libACE.a...

忽然发现。。。有这样引用链接库的吗？-L ？ -l ？

chunyv

搞定了

g++ -o list list.cpp -I/usr/local/include/ -L/usr/local/lib -l ACE


还是不行，需要这样

g++ -o list list.cpp -I/usr/local/include/ -lpthread -L/usr/local/lib -l ACE


搞不清楚为什么linux可以不需要这个-lpthread ....
