cmake setup for analysis tools

[Prasun Ratn]

I am trying to set up cmake based build for a drmemtrace analyzer and I am following the directions from the "Creating New Analysis Tools" page https://dynamorio.org/sec_drcachesim_newtool.html

This is my CMakeLists.txt

    cmake_minimum_required(VERSION 3.10)
    project(analyzer_example)

    find_package(DynamoRIO)
    if (NOT DynamoRIO_FOUND)
        message(FATAL_ERROR "DynamoRIO package required to build")
    endif(NOT DynamoRIO_FOUND)

    set (target analyzer_example)
    add_executable (${target} ${target}.cpp)

    # The target OS:
    if (APPLE)
        set(MACOS 1)
    elseif (UNIX)
        set(LINUX 1)
    endif (APPLE)
    if (WIN32)
        set(WINDOWS 1)
    endif (WIN32)

    if (LINUX)
        target_compile_definitions(${target} PRIVATE -DLINUX -DUNIX)
    elseif (WINDOWS)
        target_compile_definitions(${target} PRIVATE WINDOWS)
    endif (LINUX)

    target_compile_definitions(${target} PRIVATE X86_64 X64)

    configure_DynamoRIO_main_headers()
    use_DynamoRIO_drmemtrace(${target})

This is my analyzer_example.cpp

    #include "analysis_tool.h"
    #include <string>

    int main()
    {
        return 0;
    }

On compiling, I get this error

    fatal error: analysis_tool.h: No such file or directory
        1 | #include "analysis_tool.h"

I also tried adding configure_DynamoRIO_main_headers() in CMakeLists.txt but it did not help.

I am able to compile if I change the include to this

    #include "drmemtrace/analysis_tool.h"

Is my CMakeLists.txt set up incorrectly?

It looks like use_DynamoRIO_drmemtrace() adds the base include/ dir to the compiler search dirs, and the headers for drmemtrace are in the drmemtrace/ subdir of that base include/ dir, so it looks like you would be expected to use the #include "drmemtrace/analysis_tool.h"?  Probably that documentation page should explicitly say that?  I wonder if you could send a pull request making that clearer (plus anything else you found confusing on that page).

Thanks. I wasn't sure if that was needed or if I was doing something wrong.

I added a small example https://github.com/DynamoRIO/dynamorio/pull/5880
