Я пытаюсь собрать библиотеку clFFT (для выполнения FFT с OpenCL) и примеры, содержащиеся в clFFT git.
1) Сначала в /opt/ я сделал:
git clone https://github.com/clMathLibraries/clFFT.git
2) После того, как всегда в каталог /opt/, я сделал: $ mkdir build && cd build/
3) отсюда я позвонил cmake вот так:
cmake -DOpenCL_INCLUDE_DIR=/opt/AMDAPPSDK-3.0/include -DOpenCL_LIBRARY=/opt/AMDAPPSDK-3.0/lib/x86_64 ../clFFT/src/
Действительно, в каталог /opt/ я установил AMDAPPSDK-3.0 из архива AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2.
4) Кажется, все верно для компиляции clFFT, но это не удается:
4.1) Сначала, в конце указанной выше команды cmake, я получаю:
cmake -DOpenCL_INCLUDE_DIR=/opt/AMDAPPSDK-3.0/include -DOpenCL_LIBRARY=/opt/AMDAPPSDK-3.0/lib/x86_64 ../clFFT/src/

Я не понимаю, откуда могут возникнуть эти ошибки, похоже, что библиотека libclFFT.so.2.14.0, которую я построил, не содержит ссылок на основные функции OpenCL (например, clGetPlatformIDs или clCreateCommandQueue ...).
Более того, я не знаю, почему путь неопределенной ссылки находится на верхнем уровне, то есть /usr/bin/ld: ../library/libclFFT.so.2.14.0, поскольку библиотека встроена в /opt/build/library каталог
Я бы хотел иметь возможность скомпилировать libclFFT.so, который учитывает заголовки OpenCL, обозначенные путем OpenCL_INCLUDE_DIR и библиотеку OpenCL_LIBRARY.
Мне нужно решить эту проблему с путем, принятым cmake, то есть: ../library/libclFFT.so.2.14.0, и включить в сборку этой библиотеки все функции OpenCL из AMDAPP SDK.
Любая помощь приветствуется, с уважением
