我正在尝试构建一个简单的程序来测试外部库的使用,但在将它与g++连接时遇到了困难。见命令/结果:
user@user-Nuvo-2510VTC:~/Desktop/WDT_DIO/linux/test$ g++ -o main main.o -lwdt_dio

我想学习llvm,所以我不得不在我的ubuntu14.04中安装clang,但我遇到了一些problems.Here:
当我执行command:sudo apt-get install clang-3.5时,我得到一些错误消息,如下所示:
Reading package lists... Done Building dependency tree Reading
state information... Done Some packages could not be installed. This

当我试图在Ubuntu Trusty上构建Plasma5时,我遇到了一个与eglibc2.19相关的问题。
/usr/lib/x86_64-linux-gnu/libc_nonshared.a(lstat64.oS): In function ``lstat64': (.text+0xc): undefined reference to ``__lxstat64'
我不知道该怎么解决这个问题。谢谢。

将-v附加到g++和ld,got:COLLECT_GCC=/etc/alternatives/g++ COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86
这里有什么问题吗?我有以下简单的课程:
#include "libmnl/libmnl.h"
int main() {
struct mnl_socket *a = mnl_socket_open(12);
}
在运行简单的gcc编译(gcc -lmnl main.c)之后,我得到以下错误:
/tmp/cch3GjuS.o: In function `main':
main.c:(.text+0xe): undefined reference to `mnl_socket_open'
collect2: ld returned 1 exit stat
我正在使用openSUSE进行自动安装AutoYAST系统的工作,并且在一个小细节上遇到了困难。为了在用户的环境中设置相关的应用程序,我尝试将符号链接到/usr/local/bin中的所有应用程序中(所以说/usr/local/bin有addr2line实用程序,那么我想要一个指向~/bin中的应用程序的符号链接)。
为了实现这一点,我尝试执行以下代码片段:
su -c "for program in `ls /usr/local/bin`; do ln -s /usr/local/bin/$program ~/bin/$program; done" <user>
最近我升级到gcc-4.9,但它完全破坏了我的clang++,我无法编译任何东西。我正在收到的错误:
In file included from src/tester.cpp:11:
In file included from /usr/include/boost/progress.hpp:22:
In file included from /usr/include/boost/timer.hpp:20:
In file included from /usr/include/boost/config.hpp:40:
In file included from /usr/include/boos
我按照github中的这些说明克隆并构建了boost库。
./b2命令的末尾告诉我
Boost C++库已成功构建!
The following directory should be added to compiler include paths:
/home/user/Desktop/boost
The following directory should be added to linker library paths:
/home/user/Desktop/boost/stage/lib
我应该如何处理这些文件夹?我想把boost放在“为了让gcc看到它而应该去
