Question

当我想为我的代码创建静态构建时（我想在服务器上运行此代码）我遇到了一个奇怪的问题：

我的cmake看起来完全像这样：

cmake_minimum_required(VERSION 2.8.9)

set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake)
project(crypto)

set(PROJECT_NAME "crypto")

find_package(NTL REQUIRED)

include(CheckCXXCompilerFlag)
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)
CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)

if(COMPILER_SUPPORTS_CXX11)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
elseif(COMPILER_SUPPORTS_CXX0X)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x -pthread")
else()
        message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")
endif()

SET(CMAKE_EXE_LINKER_FLAGS "-static -lntl -lgmpxx -lgmp -lm")

add_executable(crypto main.cpp elliptic_curve.cpp point.cpp lenstra.cpp pollard_algorithm.cpp ThreadPool.cpp)
target_link_libraries(crypto ${NTL_LIBRARY})

我真的不知道我做错了什么，我会感激任何帮助。

更新：

我安装了gmp和ntl：

⋊> ~/D/gmp-6.1.0 ls ~/sw/lib/libntl.a        
/home/piotr/sw/lib/libntl.a
⋊> ~/D/gmp-6.1.0 ls /usr/local/lib/libgmp.a     
/usr/local/lib/libgmp.a
⋊> ~/D/gmp-6.1.0 ls /usr/local/lib/libgmpxx.a   
/usr/local/lib/libgmpxx.a

当我删除行时：

SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")

来自cmake，我可以正常编译而没有任何问题我的代码。但我需要一个静态编译来在服务器上执行此代码，但是现在我的构建设置是不可能的，我不知道为什么。

我还有正确的FindNTL.cmake文件，如下所示：

FIND_PATH(NTL_INCLUDE_DIR RR.h
  HINTS
  $ENV{NTLDIR}
  PATH_SUFFIXES NTL include/NTL include
  PATHS
  ~/sw #
)

FIND_LIBRARY(NTL_LIBRARY
  NAMES ntl
  HINTS
  $ENV{NTLDIR}
  PATH_SUFFIXES lib64 lib libs64 libs libs/Win32 libs/Win64
  PATHS
  ~/sw
)


# handle the QUIETLY and REQUIRED arguments and set NTL_FOUND to TRUE if
# all listed variables are TRUE
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(NTL DEFAULT_MSG  NTL_LIBRARY NTL_INCLUDE_DIR)

MARK_AS_ADVANCED(NTL_LIBRARY NTL_INCLUDE_DIR)

使VERBOSE = 1

/usr/bin/cmake -E cmake_link_script CMakeFiles/crypto.dir/link.txt --verbose=1

Answer 1

根据来自@Tsyvarev的提示，我做了一些更改，并使用详细的make运行make，最后我得到make命令，如下所示：

g++ -std=c++11 -static -lgmpxx -lgmp -lm CMakeFiles/crypto.dir/main.cpp.o CMakeFiles/crypto.dir/elliptic_curve.cpp.o CMakeFiles/crypto.dir/point.cpp.o CMakeFiles/crypto.dir/lenstra.cpp.o CMakeFiles/crypto.dir/pollard_algorithm.cpp.o CMakeFiles/crypto.dir/ThreadPool.cpp.o  -o crypto -rdynamic /home/piotr/sw/lib/libntl.a

但不假思索地结束了错误：

/usr/bin/ld: /usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0/crtbeginT.o: relocation R_X86_64_32 against `__TMC_END__' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0/crtbeginT.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

使用clang ++代替g ++时出错：

/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality in `/usr/bin/../lib64/gcc/x86_64-unknown-linux-gnu/5.3.0/../../../../lib64/libc.a(strcmp.o)' can not be used when making an executable; recompile with -fPIE and relink with -pie
clang-3.7: error: linker command failed with exit code 1 (use -v to see invocation)

所以我想我需要用-fPIE选项重新编译libc库

无法将静态程序与ntl库链接
