Finally I got the Yices working by adding yices-2.1.0/bin to my path. Still looking to resolve Z3. Regards, Mukesh Tiwari On Mon, Jul 1, 2013 at 3:42 PM, mukesh tiwari wrote:

I also tried installing Yices[1] but still getting same error. I followed the instructions but still the same error. Seems like I am missing some crucial details about path but not able to resolve it.

This file is part of the Yices 2.0 binary distribution for MacOS X. Yices is distributed free-of-charge for personal use under the terms of the Yices license (see LICENSE).

Content -------

This distribution includes three solvers

bin/yices (for the Yices 2 language) bin/yices-smt (for SMT-LIB 1.2) bin/yices-sat (sat solver, DIMACS format)

and the Yices libraries and header files

lib/libyices.2.0.0.dylib include/yices.h include/yices_types.h include/yices_limits.h include/yices_exit_codes.h

Examples and documentation are in the examples and doc directories.

The binaries and library were linked statically against GMP version 5.0.4, copyright Free Software Foundation (see NOTICES).

Recommended Library Installation on MacOS X -------------------------------------------

The library's install name is '/usr/local/lib/libyices.2.dylib' so the following procedure should be used to install it.

1) copy libyices.2.0.0.dylib in /usr/local/lib (this requires administrative privileges):

sudo cp libyices.2.0.0.dylib /usr/local/lib sudo chmod 755 /usr/local/lib/libyices.2.0.0.dylib

2) add two symbolic links:

sudo ln -sf libyices.2.0.0.dylib /usr/local/lib/libyices.dylib sudo ln -sf libyices.2.0.0.dylib /usr/local/lib/libyices.2.dylib

Hello all, Not directly related to Haskell but I am trying to install Z3 to use SBV package[1]. I followed the instructions[2] to install it.

*Mukeshs-MacBook-Pro:SMT mukeshtiwari$ git clone https://git01.codeplex.com/z3 -b unstable Cloning into 'z3'... remote: Counting objects: 16070, done. remote: Compressing objects: 100% (3928/3928), done. remote: Total 16070 (delta 12057), reused 16070 (delta 12057) Receiving objects: 100% (16070/16070), 7.62 MiB | 287 KiB/s, done. Resolving deltas: 100% (12057/12057), done.*

After installing Z3 *Running python example.py in z3/examples/python gives this result. * *Mukeshs-MacBook-Pro:python mukeshtiwari$ python example.py sat [y = 4, x = 2]*

but when I am running sbv package, I am getting this error.

I have posted every details on installation on pastebin[3]. The documentation file says that[4] it will install

*2) Building Z3 using make/g++ and Python Execute:

autconf ./configure python scripts/mk_make.py cd build make sudo make install

It will install z3 executable at /usr/bin, libraries at /usr/lib, and include files at /usr/include.*

Mukeshs-MacBook-Pro:z3 mukeshtiwari$ echo $PATH

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/mukeshtiwari/Programming/GHC/ghc-7.6.1/bin:/Users/mukeshtiwari/.cabal/bin:/Users/mukeshtiwari/Erlang/bin:/Users/mukeshtiwari/Programming/Scala/scala-2.10.0/bin:/usr/local/smlnj-110.75/bin:/Users/mukeshtiwari/.rvm/bin

Could some one please tell me how to solve this problem.

Only applicable on Linux (and setting the OS X equivalent of LD_LIBRARY_PATH is an absolutely wonderful way to break your system). OS X compiles full paths to shared objects into binaries, and provides a tool to change them if the need arises (install_name_tool). -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Thank you for your response. Now it's working. -Mukesh Tiwari On Mon, Jul 1, 2013 at 8:32 PM, Levent Erkok wrote:

SBV should be able to pick up Z3 from your path; make sure the "z3" executable is in it and you can invoke it from your shell. Alternatively, you can use the SBV_Z3 environment variable to point to the executable itself, if adding it to your path is not desirable for whatever reason.

Let me know if you still have issues.

Unable to locate executable for z3

well, do you really have z3 in the $PATH? what does 'which z3' answer?

I used this for installation of z3: python scripts/mk_make.py --prefix=/usr/local

and note that the install script says:

Z3 shared libraries were installed at /usr/local/lib, make sure this directory is in your LD_LIBRARY_PATH environment variable.
