Связывание внешней архивной библиотеки cblas с помощью cmake

2 голосов
/ 12 января 2020

Я загрузил и собрал (казалось бы, правильно) соответствующие библиотеки BLAS и CBLAS (с netlib.org/blas) в моей среде Linux Fedora. Результатом этого стал файл blas_LINUX.a, который я переименовал в libblas.a и скопировал в \usr\local\lib, и файл cblas.h, который я скопировал в \usr\include. Впоследствии я попытался сослаться на это в файле CMakeList.txt в проекте CLion. Файл выглядит следующим образом: 

project(test C)
cmake_minimum_required(VERSION 3.10)

set(CMAKE_C_STANDARD 99)

include_directories(include)

add_executable(${PROJECT_NAME} src/main.c)

find_library(blas libblas.a /usr/local/lib)
MESSAGE(STATUS "CBLAS location is: " ${blas})

target_link_libraries(${PROJECT_NAME} ${blas})

Судя по сообщению, которое cmake выдает при перезагрузке, библиотека cblas, похоже, в порядке. Однако, когда я пытаюсь запустить свое приложение, я получаю следующее сообщение об ошибке компоновщика: 

undefined reference to `cblas_dgemm`

Ниже приводится содержимое моего main.c файла 

#include <stdio.h>
#include <stdlib.h>

#include <cblas.h>

int main(int arg, char *args[]) {

  .
  .
  .

    printf("Processing cblas_dgemm matrix multiplication.\n");
    cblas_dgemm(CblasRowMajor, CblasNoTrans, CblasNoTrans, N, N, N, alpha, A[0], N, B[0], N, beta, C[0], N);

  .
  .
  .
    return 0;
}

Я не совсем уверен, что я здесь не так. Я очень новичок в использовании cmake, и я хожу по кругу, пытаясь выяснить, в чем проблема, при поиске в Интернете. Любые указатели в правильном направлении будут приняты и оценены.

Исправление (CMakeOutput.txt выглядит следующим образом) 

The system is: Linux - 5.4.8-200.fc31.x86_64 - x86_64
Compiling the C compiler identification source file "CMakeCCompilerId.c" succeeded.
Compiler: /usr/bin/cc 
Build flags:

The output was:

Compilation of the C compiler identification source "CMakeCCompilerId.c" produced "a.out"

The C compiler identification is GNU, found in "/home/xxx.xxx/CLionProjects/assignment_2/cmake-build-debug/CMakeFiles/3.15.3/CompilerIdC/a.out"

Determining if the C compiler works passed with the following output:

Ваш файл CMakeLists.txt должен выглядеть примерно так, следуя предложению FindBLAS: 

include(FindBLAS)

if (BLAS_FOUND)
    target_compile_options(${PROJECT_NAME} PRIVATE ${BLAS_LINKER_FLAGS})
    target_link_libraries(${PROJECT_NAME} ${BLAS_LIBRARIES})
endif ()

Я не знаю, как именно вы сгенерировали libblas.a, но вы можете взглянуть на директиву FindBLAS CMake. (Обратите внимание на примечание относительно C / C ++)

Есть куча вещей, которые могут go ошибиться, но для упрощения:

  1. скопируйте libblas.a в тот же каталог, что и ваша программа
  2. Ссылка явно в make-файле.
  3. Проверьте, чтобы увидеть расположение CBLAS в вашем выводе (не показан)
  4. Проверьте разрешения libblas.a и посмотрите на символы, используя nm
  5. Заставить CMake связать все статически (например, здесь stati c link question

Ваши симптомы свидетельствуют о том, что вы собираете какую-то другую библиотеку blas при компиляции, но не при во время выполнения.

Похоже, что динамический c компоновщик не может найти общую библиотеку.

Вы можете использовать ldd для проверки динамических c зависимостей

Пример просмотра зависимостей / bin / ls
