Can you help diagnose this, as I'm not able to reproduce this.
What does this command give you?
$ file /home/michael/dev/cmake/Tests/BundleUtilities/testbundleutils1
I get this:
./testbundleutils1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped
Also, can you try the patch I'm attaching to see if it changes anything? |

I get a similar output:
/home/michael/dev/cmake/Tests/BundleUtilities/testbundleutils1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
Unfortunately, the patch doesn't change the test output in any way.
Thanks for the response, and please let me know anything else I can provide to help track this down. |

When running the test manually:
./testbundleutils1: error while loading shared libraries: libshared.so: cannot open shared object file: No such file or directory |

The problem is that your file command did not print the keyword "executable"
We need to find out why and fix that, modify getprerequisites.cmake to recognize the alternate output, or use a different tool.
The problem running it is because it has absolute rpaths built in that it needs to be installed to run, but your install step in the test doesn't work. |

What version of file are you using? I have 5.11 here. |

I'm using 5.04 and my /etc/magic and /usr/share/misc/magic are empty.
Perhaps you have local definitions that change these words (the man page says to avoid that). |

I get the same output with 5.04, and both those are empty too. |

Does "objdump -f testbundleutils1" give EXEC_P among others?
What compile flags were used to build it?
What does "file libshared.so" give? |

Try this:
cd Tests/BundleUtilities
rm testbundleutils1
make VERBOSE=1 testbundleutils1/fast
My flags building the thing are:
/usr/bin/c++ CMakeFiles/testbundleutils1.dir/testbundleutils1.cpp.o -o testbundleutils1 -rdynamic libshared.so libframework.so -ldl -Wl,-rpath,/home/cjstimp/cmake/build/Tests/BundleUtilities/testdir1
What do you have? |

Sorry, I thought you meant something else. My mistake. |

Hmm... I'm not sure where the difference is coming from. Which OS is this?
And why don't the elf headers for these binaries have the executable bit marked.
Maybe there is a different default compiler or linker flag.
Can you attach the link.txt file created from the following command?
echo "int main(){}" > test.cpp && g++ -v -Wl,--verbose test.cpp >& link.txt |

The requested output has been attached.
I'm running Gentoo Linux, with GCC 4.7.1 |

Ok, that's it... If I add the -pie linker flag, I get the same problem! |
