Я пытаюсь установить plexe-sumo с помощью cmake.Я следовал учебному пособию на plexe.car2x.org и вот результаты:
-- CMAKE_BUILD_TYPE: Release
-- CMAKE_BINARY_DIR: /home/cc/src/plexe-sumo/build-release
-- CMAKE_SOURCE_DIR: /home/cc/src/plexe-sumo
--
-- Platform:
-- Host: Linux4.15.0-34-genericx86_64
-- CMake: 3.12.2
-- CMake generator: Unix Makefiles
-- CMake build tool: /usr/bin/make
--
-- Found Proj: /usr/lib/x86_64-linux-gnu/libproj.so
CMake Error at /usr/local/share/cmake-3.12/Modules/UseSWIG.cmake:627 (add_custom_target):
add_custom_target cannot create target "libsumo_swig_compilation" because
another target with the same name already exists. The existing target is a
custom target created in source directory
"/home/cc/src/plexe-sumo/src/libsumo". See documentation for policy
CMP0002 for more details.
Call Stack (most recent call first):
src/libsumo/CMakeLists.txt:39 (SWIG_ADD_LIBRARY)
-- Enabled features: Linux-4.15.0-34-generic Proj GUI GDAL OSG GL2PS SWIG
-- Configuring incomplete, errors occurred!
Нет файла с именем 'libsumo_swig_compilation' в папке "/ home / cc / src / plexe-sumo / src / libsumo".
Затем я проверил файл журнала ошибок, но показанные ошибки касаются pthread, говоря «неопределенная ссылка на pthread_creat» и «не удается найти -lpthreads».На самом деле моя библиотека pthread установлена по адресу 'libc6: /lib/x86_64-linux-gnu/libpthread.so.0'.
Так что мне было интересно, в чем именно заключается проблема и как ее решить.Я использую виртуальную машину с Ubuntu 16. Я ценю вашу помощь!
Ниже приведен файл журнала ошибок:
