Question

我正在使用命令cmake .. -G "CodeBlocks - Ninja编译我的项目，它工作正常，但是当我运行valgrind时它不会显示任何行号。这是我正在使用的valgrind命令：valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --log-file="log.txt" ./pony_gpExe。

以下是输出示例：

==5402== Use of uninitialised value of size 8
==5402==    at 0x40447B: get_double_arr_length (in /home/robbie/Dropbox/MIT/pony_gp_ubuntu/build/pony_gpExe)
==5402==    by 0x405184: get_test_and_train_data (in /home/robbie/Dropbox/MIT/pony_gp_ubuntu/build/pony_gpExe)
==5402==    by 0x4027B3: setup (in /home/robbie/Dropbox/MIT/pony_gp_ubuntu/build/pony_gpExe)
==5402==    by 0x402861: main (in /home/robbie/Dropbox/MIT/pony_gp_ubuntu/build/pony_gpExe)
==5402==  Uninitialised value was created by a stack allocation
==5402==    at 0x405149: get_test_and_train_data (in /home/robbie/Dropbox/MIT/pony_gp_ubuntu/build/pony_gpExe)

不确定这是否有用，但这是我的主要CMakeLists.txt：

cmake_minimum_required(VERSION 3.4.3)
project (pony_gp)
set(DIR ${pony_gp_SOURCE_DIR})

file(GLOB_RECURSE pony_gp_SOURCES "${DIR}/src/*.c")
file(GLOB_RECURSE pony_gp_HEADERS "${DIR}/include/*.h")

foreach (_headerFile ${pony_gp_HEADERS})
    get_filename_component(_dir ${_headerFile} PATH)
    list (APPEND pony_gp_INCLUDE_DIRS ${_dir})
endforeach()
list(REMOVE_DUPLICATES pony_gp_INCLUDE_DIRS)

include("${DIR}/include/CMakeLists.txt")
include_directories(${pony_gp_INCLUDE_DIRS})
add_executable (pony_gpExe ${pony_gp_SOURCES})

if (CMAKE_COMPILER_IS_GNUCC)

    target_link_libraries(pony_gpExe m)

    find_program(MEMORYCHECK_COMMAND valgrind)
    set(MEMORYCHECK_COMMAND_OPTIONS "--trace-children=yes --leak-check=full")
    set(MEMORYCHECK_SUPPRESSIONS_FILE "${DIR}/valgrind_suppress.txt")
endif()

include(CTest)
add_test(test pony_gpExe)

Answer 1

您需要告诉cmake生成调试可执行文件。没有看到你的cmake配置，很难告诉你如何做到这一点，但默认/约定，它应该是：

cmake -DCMAKE_BUILD_TYPE=Debug

有关其他信息，请参阅Debug vs Release in CMAKE上的此答案。

我希望您使用<%= render 'shared/navbar' unless (controller.controller_name == "messages" && controller.action_name == "new") || (controller.controller_name == "links" && controller.action_name == "edit") || (controller.controller_name == "messages" && controller.action_name == "edit") %> <%= render 'shared/sidebar' unless current_page?(root_path) || current_page?(edit_user_registration_path) || (controller.controller_name == "companies" && controller.action_name == "index") || (controller.controller_name == "companies" && controller.action_name == "create") || (controller.controller_name == "companies" && controller.action_name == "new") || current_page?(new_company_path) || (controller.controller_name == "links" && controller.action_name == "edit") || (controller.controller_name == "messages" && controller.action_name == "new") || (controller.controller_name == "messages" && controller.action_name == "edit") %>编译代码并假设您在-g或Ubuntu

中运行代码

尝试运行这样的Mac OS，它可以解决Ubuntu中的问题

所以，我不知道为什么，但随机的valgrind开始显示行号...我没有做任何不同的事情，但无论哪种方式都有效......

Valgrind在使用cmake编译时没有显示行号
