dynamic linking error dlopen(libJerasure.dylib, 5): image not found

[Shafiul hasan]

Hi All,

I am getting this error while trying to running the test suites. My os version is

OS X Tosemite 10.10.3 Xcode Version 6.3.1

Here is the error trace messages,

May 4 01:33:37 **-MacBook-Air.local liberasurecode[17983] <Error>: liberasurecode_backend_open: dynamic linking error dlopen(libJerasure.dylib, 5): image not found Backend library not available!

I have a tight schedule to complete a project which was depending on your library. if possible please have a look.

I know that OSX uses difference compiler to compile the library, please suggest me any way-around if possible.

I might need to install jerasure lib separately. I am trying to install that and check it again.

@tareq_sust please let us know what you find out here.

The issue still persists.

I have install gf-complete and then jerasure . I run their test scripts and all test case passed. Then i wanted to build the liberasurecode , while running the autogen script i was getting these Logs with some warnings ,

After that i run the necessary commands and while running the make test command i am getting several failed test cases,

like this one,

ok 0 - create_and_destroy_backend: null (idx=0) May 4 15:33:12 Shafiuls-MacBook-Air.local liberasurecode[6744] <Error>: liberasurecode_backend_open: dynamic linking error dlopen(libnullcode.dylib, 5): image not found Backend library not available!

Seems that liberasurecode could not linking with libjerasure . I have checked my /usr/local/lib folder and all files are there

Please have a look :(.

[Shafiul hasan]

Seems that jerasure and gf-complete has some problem or i could not compile those properly.

To verify my setup , i download pyeclib and run the unit tests and got this error.

[Kevin Greenan]

@tareq_sust This is not a Jerasure or gf-complete problem, it is an issue with dlopen() on OS X.

@tsg- What ended up working for Clay's problem on his Mac? Was it setting DYLD_LIBRARY_PATH?

[Tushar Gohad]

@kmgreen2 yes, setting DYLD_LIBRARY_PATH seemed to have worked for him.

Marking resolved. Please reopen if needed.
