Summary0013497: CMAKE_SKIP_INSTALL_RPATH removes RPATH but leaves empty RUNPATH.
DescriptionHello,

I used the downloadable binary version of cmake for this test.

If I do not specify options for RPATH specific features, then the behaviour is the same - this is probably the default anyway.

My first question is that if this behaviour (= empty RUNPATH) is intendend?

Since I assume not, both fields, RPATH and RUNPATH, should always have the same contents or should both not exist at all. I could use CMAKE_BUILD_WITH_INSTALL_RPATH or CMAKE_SKIP_BUILD_RPATH which works around the problem, but then of course I would not be able to run programs from the build directory.

Thank you for your answer,

Martin Lederhilger
Steps To ReproducePlease see the test case in the attached tar.gz-file.

An issue very similar to this was fixed as of CMake 2.8.0:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=2a85f828 [^]

The implementation as of 2.8.9 is here:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmSystemTools.cxx;hb=v2.8.9#l2694 [^]

I added these lines to your example to enable DT_RUNPATH on my system:

 set(CMAKE_SHARED_LINKER_FLAGS "-Wl,--enable-new-dtags")
 set(CMAKE_EXE_LINKER_FLAGS "-Wl,--enable-new-dtags")

but I cannot reproduce the problem:

 $ cd build
 $ cmake --version
 cmake version 2.8.9
 $ cmake .. -DCMAKE_INSTALL_PREFIX="$(pwd)/../install"
 $ make
 $ readelf -d libb/libb.so |grep PATH
  0x000000000000000f (RPATH) Library rpath: [.../build/liba:]
  0x000000000000001d (RUNPATH) Library runpath: [.../build/liba:]
 $ readelf -d prg |grep PATH
  0x000000000000000f (RPATH) Library rpath: [.../build/libb:.../build/liba:]
  0x000000000000001d (RUNPATH) Library runpath: [.../build/libb:.../build/liba:]

 $ make install
 -- Installing: .../install/bin/prg
 -- Removed runtime path from ".../install/bin/prg"
 -- Installing: .../install/liba/liba.so
 -- Installing: .../install/libb/libb.so
 -- Removed runtime path from ".../install/libb/libb.so"
 $ readelf -d ../install/bin/prg |grep PATH
 $ readelf -d ../install/libb/libb.so |grep PATH

Please attach the actual "libb.so" and "prg" binaries from your build tree so I can see the difference.

Hmm, since I do not want to use RUNPATH anyway, I could use

set(CMAKE_SHARED_LINKER_FLAGS "-Wl,--disable-new-dtags")
set(CMAKE_EXE_LINKER_FLAGS "-Wl,--disable-new-dtags")

. But it would still be nice, if everything works;)

Great, thanks. Now I'm able to reproduce it but *only* with the pre-compiled binary from the download page. The problem is here:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmELF.cxx;hb=v2.8.9#l126 [^]
 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmELF.cxx;hb=v2.8.9#l333 [^]

in combination with the version of Linux on which the binary is built being so old that it does not define DT_RUNPATH.

I think a workaround like this might work:

#if !defined(DT_RUNPATH) && defined(__linux) && DT_NUM <= 29
# define DT_RUNPATH 29
#endif


or just adding -DDT_RUNPATH=29 to the compilation on that machine.

Thank you, I have compiled cmake from source and now it works perfectly.

This should correct the build on our binary release machine:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=c0f89e9c [^]

We'll build 2.8.10 and newer binaries like that.

We may also build new binaries for older versions and will update the download links accordingly.
