emcmake cannot find Boost

mpconte commented 2 years ago

Please include the following in your bug report:

Version of emscripten/emsdk: emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.11 (85c8b762740b866884088ba3832cb8b20e277873) clang version 15.0.0 (https://github.com/llvm/llvm-project 295d032762ad284068c72cc1904680a4db5e80d3) Target: wasm32-unknown-emscripten Thread model: posix InstalledDir: /root/emsdk/upstream/bin

When running standard cmake, the find_package command in my CMakeLists.txtseems to find all boost libraries fine, but the same CMakeLists.txt when run via emcmake cmake, I get the following error:

configure: cmake .. -DCMAKE_TOOLCHAIN_FILE=/root/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DCMAKE_CROSSCOMPILING_EMULATOR=/root/emsdk/node/14.18.2_64bit/bin/node;--experimental-wasm-threads

As per the requirement, I have installed libboost-all-dev on my debian distro container first to ensure boost was installed on my machine

I've discovered that my issue was resolved by excluding the COMPONENTS portion of the Boost find_package line in the CMakeLists.txt below (commented out). Seems like a strange workaround for what otherwised worked in the standard cmake (v 3.16.3)

cmake_minimum_required (VERSION 3.5)
project (SAMPLE)

# Use C++ 17 compiler standard
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DBOOST_BIND_GLOBAL_PLACEHOLDERS")

# include support for modern C++ language features across the build
if (WIN32 OR MSVC)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /wd4996 /wd4251")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} /wd4996")
    set(CMAKE_MODULE_PATH "${CMAKE_PREFIX_PATH}; C:/Program Files (x86)/GnuWin32")
elseif (ARM)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Os -Wall -Wextra -Wno-unused-parameter -Wno-unknown-pragmas")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Os ")
else ()
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Os -Wall -Wextra -Wno-unused-parameter -Wno-unknown-pragmas")
    set(CMAKE_CXX_FLAGS_DEBUG="-g -O0 -Wall -Wextra -Wno-unused-parameter -Wno-unknown-pragmas")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Os ")
    set(CMAKE_C_FLAGS_DEBUG="${CMAKE_C_FLAGS} -g -O0 ")
endif(WIN32 OR MSVC)

include_directories("${PROJECT_BINARY_DIR}")

# Find python and numpy

#include_directories(${Python3_INCLUDE_DIRS})
#include_directories(${Python3_Numpy_INCLUDE_DIRS})

# we need to tell the linker to use the sysroot (although the compiler does this automatically).
if (CMAKE_SYSROOT)
    set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} --sysroot=${CMAKE_SYSROOT} -lrt -lpthread -lresolv")
    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} --sysroot=${CMAKE_SYSROOT} -lrt -lpthread -lresolv")
endif()

# tell the installer where to put our output files. DESTDIR will be prefixed to this.

    set (CMAKE_INSTALL_PREFIX ${PROJECT_SOURCE_DIR})

    find_package(Boost COMPONENTS unit_test_framework iostreams system serialization thread program_options python numpy filesystem REQUIRED )
elseif (arm)
    find_package(Boost 1.65.1 REQUIRED unit_test_framework iostreams system serialization thread program_options python numpy filesystem)

    find_package(Boost REQUIRED )# COMPONENTS iostreams program_options filesystem  )
endif(WIN32 OR MSVC)
include_directories(${Boost_INCLUDE_DIRS})
include_directories(${PROJECT_SOURCE_DIR})
include_directories(${PROJECT_SOURCE_DIR}/code)

# Now we invoke each of our project sub-directories (they must each have a CMakeLists.txt file).

I have the same problem，but only use find_package(Boost REQUIRED )，it's also not work

emscripten-core / emscripten

emcmake cannot find Boost #17039
