Question

我正在尝试在IBM BlueGene机器上使用CMake编译Fortran程序。这是我的来源：

 > tree
.
├── CMakeLists.txt
└── src
    └── test1.f90

其中test1.f90只是：

program main
    use mpi
    integer   :: me, ierr

    call MPI_Init(ierr)
    call MPI_Comm_rank(MPI_COMM_WORLD, me, ierr)
    write (*,"(I4,A)") me, ": hello"
    call MPI_Finalize(ierr)
end program main

我想创建静态可执行文件。因此我创建了这个CMakeLists.txt：

cmake_minimum_required(VERSION 2.5)
project(STB)

file(GLOB_RECURSE sources  src/*.f90)

SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")
add_executable(test.x ${sources})

enable_language(Fortran)
set(CMAKE_Fortran_COMPILER_ID "IBM")

if(CMAKE_Fortran_COMPILER_ID MATCHES "IBM")
    MESSAGE(STATUS "IBM")
    set(CMAKE_Fortran_COMPILER mpixlf2008)
    set(dialect "-O2 -qarch=qp -qtune=qp -ufmt_littleendian={23}")
    set(debug "-C")
endif()


set(CMAKE_Fortran_FLAGS_DEBUG "${CMAKE_Fortran_FLAGS_DEBUG} ${bounds}")
set(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} ${dialect}")

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
MESSAGE( STATUS "cmake_module_path:    " ${CMAKE_MODULE_PATH})

这导致：

如果我在没有-rdynamic

的情况下重新运行最后一个参数

mpixlf2008   -static  -O2 -qarch=qp -qtune=qp -ufmt_littleendian={23} CMakeFiles/test.x.dir/src/test1.o  -o test.x

我收到错误：

/bgsys/drivers/ppcfloor/gnu-linux/powerpc64-bgq-linux/bin/ld: -f may not be used without -shared

如何使用CMake静态编译我的程序？如果我只是跑：

mpixlf2008 -c src/test1.f90
mpixlf2008 test1.o -o bla.x

编译工作正常，大小（45M）表明，它是静态编译的。

修改

如果我删除小端标志：

set(dialect "-O2 -qarch=qp -qtune=qp")

我可以运行cmake创建的makefile，然后手动删除-rdynamic

mpixlf2008 -static -O2 -qarch=qp -qtune=qp CMakeFiles/test.x.dir/src/test1.o -o test.x

然后成功编译。如何从CMake Makefile中删除-rdynamic？

Answer 1

尝试将-qstaticlink添加到链接行，而不是直接添加-static / -rdynamic。当您使用mpixlf2008命令时，编译器会在其自己的库中插入自己的-static / -rdynamic选项以进行链接，因此您添加的选项可能会干扰编译器正在使用的选项。 -qstaticlink选项告诉编译器您需要一个完全静态的二进制文件。该选项还有子选项，允许您仅静态链接gcc库。

此外，您获得的具体错误是因为您指定了＆＃34; -rdynamic＆＃34;。 XLF不知道这个选项，所以它假设它是一组较小的选项。因此它将其解析为：＆＃34; -r -d -ynamic＆＃34;。 -r用于创建不可执行的输出文件，-d用于保存预处理的输出，-y用于指定编译时舍入模式。 -y选项采用舍入模式的子选项，例如： -yn是最近的。你得到的错误是namic不是-y的已知子选项。要将-rdynamic传递给链接器，请将-Wl放在它之前。即＆＃34; -Wl，-rdynamic＆＃34;。

添加

允许我删除'-rdynamic'。这可能有点手动，但对于较旧的CMake版本，它可以工作。

与IBM的mpixlf2008一起使用
