我正在我的大学集群上建立一个caffe(3D-caffe),它在/software/software/<package>/<version-compiler>/
当cmake执行此编译步骤时:
g++ -fPIC -Wall -Wno-sign-compare -Wno-uninitialized -O3 -DNDEBUG \
CMakeFiles/caffe.bin.dir/caffe.cpp.o -o caffe -rdynamic ../lib/libcaffe.so \
../lib/libproto.a /software/software/Boost/1.61.0-foss-2016a/lib/libboost_system.so \
/software/software/Boost/1.61.0-foss-2016a/lib/libboost_thread.so \

TL; DR:要点表单是(注意-lz
用于链接到libz
):
g++ ... .../caffe.cpp.o -o caffe .../libcaffe.so .../libproto.a .../libboost_system.so ...more .so's and -lxyz's... -lz
错误:
/software/software/libpng/1.6.23-foss-2016a/lib/libpng16.so.16: undefined reference to `inflateReset2@ZLIB_1.2.3.4'
collect2: error: ld returned 1 exit status
这似乎是正确的,因为当我为-print-file-name=libz.so.1
指定g++
选项时,会打印/lib/../lib64/libz.so.1
,这对于版本来说有点过于陈旧。
我在/software/software/zlib/1.2.8-foss-2016a/lib/
中有一个较新的版本,但在我:
LD_LIBARY_PATH
,-rpath
选项或-L
选项 g++
在使用/lib/../lib64/libz.so.1
-print-file-name
工作原理是删除-lz
选项并将/software/software/zlib/1.2.8-foss-2016a/lib/libz.so.1
显式添加为要在编译/链接期间包含的文件。但这似乎是一种黑客攻击。
在完成g++
选项时,如何让/software/software/zlib/1.2.8-foss-2016a/lib/libz.so.1
使用/lib/../lib64/libz.so.1
代替-lz
?最好间接通过cmake(当建造咖啡时)。
提前谢谢!
修改
ldd
说明使用的权利.so
:
# ldd /software/software/libpng/1.6.23-foss-2016a/lib/libpng16.so.16
linux-vdso.so.1 => (0x00007fff55599000)
libz.so.1 => /software/software/zlib/1.2.8/lib/libz.so.1 (0x00007f7875b29000)
libm.so.6 => /lib64/libm.so.6 (0x00007f7875888000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f787566b000)
libc.so.6 => /lib64/libc.so.6 (0x00007f78752d7000)
/lib64/ld-linux-x86-64.so.2 (0x0000003328800000)
此外,该符号应该存在于此libz.so.1:
中# nm /software/software/zlib/1.2.8/lib/libz.so.1
...
0000000000008270 T inflateReset2
...
0000000000000000 A ZLIB_1.2.3.4
....
#
我在de @
中假设undefined symbol
- 符号 - 错误某种程度上需要A型符号作为版本检查(但我找不到任何关于此的文档)在ld.so
手册页中)
答案 0 :(得分:1)
我的猜测是,您 -L
之后添加-lz
,但-L
只会-l
影响-rpath
。另请注意,LD_LIBRARY_PATH
和NaN
正在影响运行时库搜索(以及ldd输出),因此它们不会对编译产生太大影响。
