我知道有很多类似的问题,但我的问题有点不同,没有他们帮助我。
我正在使用 boost-iostreams 库,这是我的问题,我试图将我的程序与库链接:
ld -I/usr/include/boost/iostreams/ -I/usr/include/boost/iostreams/device/ -L/usr/lib/libboost_iostreams.so -lboost-iostreams fd.o -o x
结果是:
ld: cannot find -lboost-iostreams
当我试图明确地写它时:
ld -I/usr/include/boost/iostreams/ -I/usr/include/boost/iostreams/device/ --library /usr/lib/libboost_iostreams.so -lboost-iostreams fd.o -o x
它告诉我图书馆不存在:
ld: cannot find -l/usr/lib/libboost_iostreams.so
ld: cannot find -lboost-iostreams
但它确实:
$ ls -l /usr/lib/libboost_iostreams*
-rw-r--r-- 1 root root 204682 feb 4 05:28 /usr/lib/libboost_iostreams.a
lrwxrwxrwx 1 root root 20 feb 4 05:28 /usr/lib/libboost_iostreams-mt.a -> libboost_iostreams.a
lrwxrwxrwx 1 root root 28 feb 4 05:28 /usr/lib/libboost_iostreams-mt.so -> libboost_iostreams.so.1.49.0
lrwxrwxrwx 1 root root 28 feb 4 05:28 /usr/lib/libboost_iostreams.so -> libboost_iostreams.so.1.49.0
-rw-r--r-- 1 root root 94280 feb 4 05:28 /usr/lib/libboost_iostreams.so.1.49.0
关于我:
- 操作系统:Debian 7 Wheezy
- 编。语言:C++
- 编译器:g++ (Debian 4.7.2-5) 4.7.2
- 链接器:GNU ld(Debian 的 GNU Binutils)2.22
- boost库版本:1.49(来自debian repo)
谢谢!
编辑:
正确的选择应该是-lboost_iostreams
,而不是-lboost-iostreams
编辑2:
编辑后我的命令是:
ld fd.o -I/usr/include/boost/iostreams/ -I/usr/include/boost/iostreams/device/ -o x $(LIB_PATH) -lboost_iostreams
其中 libpath 是以下之一:
LIB_PATH=
LIB_PATH=-L/usr/lib/
LIB_PATH=/usr/lib/libboost_iostreams.so
LIB_PATH=/usr/lib/libboost_iostreams.a
但结果仍然是:
ld: warning: cannot find entry symbol _start; defaulting to 000000000804cc10
fd.o: In function `__static_initialization_and_destruction_0(int, int)':
fd.cpp:(.text+0xd6): undefined reference to `__dso_handle'
ld: x: hidden symbol `__dso_handle' isn't defined
ld: final link failed: Bad value
