Question

根据这一SO问题,。富隆可以通过<条码>-Wl,-rpath,$-{ORIGIN}找到同一倍的共享图书馆。因此,与可执行目录相同。

我们重新使用碎块,因此,Im添加了一种形式线。

target_link_options(Executable PRIVATE -Wl,-rpath=${ORIGIN})

to CMakeLists.txt. 这里的问题是,碎块试图将9个特性序列(>${ORIGIN}作为一个变量加以解释,将其替换为零。

迄今为止,我已尝试:

$${ORIGIN}
${ORIGIN}
${ORIGIN}
$${ORIGIN}
${ORIGIN}

其中没有一个工作。我如何能够做到这一点?

正如“Tsyvarev”评论所指出的,这在我的特定情况下是一个XY问题,因为地震有直接设计用来操纵呼吸的设施。通过这样做,我得以找到解决办法。

就我而言,为CMakeList增加了以下三条线。 t是trick。

SET(CMAKE_SKIP_BUILD_RPATH  FALSE)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)
SET(CMAKE_INSTALL_RPATH "${ORIGIN}")

请注意,我们建设过程的一部分涉及将.so复制到产出夹,以准备建造最后的柏油树脂。因此,使用<代码>-rpath=${ORIGIN}在树林中进行测试,并在Docker集装箱中最终安装可执行装置。

Answer 1

As you already noticed, you should use CMAKE_INSTALL_RPATH or INSTALL_RPATH. INSTALL_RPATH sets the rpath when installing a specific target. CMAKE_INSTALL_RPATH is the global variant, doing the same for all targets.

I also struggled, how to escape $ORIGIN. But, for me it works without escaping it at all:

set_target_properties(<target> PROPERTIES INSTALL_RPATH "$ORIGIN")

Answer 2

它不仅仅为我设置了<条码>CMAKE_INSTALL_RPATH(cmake版本3.20.2, 3.7.2):

I ve set CMAKE_INSTALL_RPATH in a high level CMakeLists. txt file:

set(CMAKE_INSTALL_RPATH "${LIB_INSTALL_PATH}:$ORIGIN")

这个例子还增加了另一个途径,从一个变数I生成的LIB_INSTALL_PATH。

关于目标分子,我有:

 set_target_properties(mytarget
   PROPERTIES
      BUILD_WITH_INSTALL_RPATH true
      LINK_OPTIONS "-Wl,--disable-new-dtags"
)

The --disable-new-dtags was need to use RPATH instead of RUNPATH (the new default) which apparently has issues.

Not adding anything to the target CMakeLists.txt file results in RPATH set to the build path:

 0x000000000000000f (RPATH)              Library rpath: [/home/brookbot/workspace/my_project/build/tgt/stuff:/home/brookbot/workspace/my_project/build/tgt]

But adding the property BUILD_WITH_INSTALL_RPATH true to the target gives me the desired result:

0x000000000000000f (RPATH)              Library rpath: [/my/install/path:$ORIGIN]

I m using readelf -d to examine the results.

I ve还核实了这一工程的基数版本3.7.2,并警告说,它生成了RUNPATH而不是RPATH。 (如-OPTIONS property is not work),但它在目标上仍为我 runs:

 0x000000000000001d (RUNPATH)            Library runpath: [/my/install/path:$ORIGIN]
