C++ 犰狳与libacml的关联问题

我正在研究一个小型神经网络，主要是作为一个训练示例（我希望在使用mlpack之前能够自己做） 所以我试着安装acml，用我的gpu加速一些矩阵运算。我无法让它工作，所以我尝试禁用它，现在我在编译时遇到了这个警告

/usr/bin/ld:警告：未找到/usr/lib64/libarmadillo.so所需的libacml\u mp.so（请尝试使用-rpath或-rpath链接）

当然，在运行时我会遇到以下错误：

/home/sapphie/Documents/CLionProjects/FirstNNTest/cmake build debug/FirstNNTest:加载共享库时出错：libacml\u mp.so:无法打开共享对象文件：没有此类文件或目录

我尝试过设置LD_LIBRARY_PATH和LIBRARY_PATH变量，尝试过修补rpath和rpath link，但什么都没有，我一直遇到这些问题

现在，如果我尝试通过cmake链接ACML，我会遇到另一组更有趣的问题

使用以下cmakelist：

cmake_minimum_required(VERSION 3.7)
project(FirstNNTest)

set(CMAKE_CXX_STANDARD 11)

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake")
find_package(Armadillo REQUIRED)
find_package(ACML REQUIRED)
include_directories(${ARMADILLO_INCLUDE_DIRS})
include_directories(${ACML_INCLUDE_DIRS})



set(SOURCE_FILES main.cpp Network.cpp Network.h Tools.h)
add_executable(FirstNNTest ${SOURCE_FILES})
target_link_libraries(FirstNNTest ${ARMADILLO_LIBRARIES} ${ACML_LIBRARIES})

---

我在这个问题上花了好几个小时，差点就要重新安装整个操作系统了。

根据错误消息，问题不在于您的项目，而在于

acml

和

gfortran

库。你有这些库吗（准确的名称在错误日志中）？ACML安装在那里，但我似乎无法在那个地方或我系统上的任何其他地方找到gfortran.so。
