mychem on osx 10.10.5

[hmpelta]

Hi I have followed instructions to install mychem on my mac (OS X yosemite 10.10.5) but I was not successful .

after typing this: mysql -u root -p < src/mychemdb_macosx.sql

I get this error :ERROR 1126 (HY000) at line 10: Can't open shared library 'libmychem.dylib' (errno: 2 dlopen(/usr/local/Cellar/mysql56/5.6.29/lib/plugin/libmychem.dylib, 2): Symbol not found: __ZN9OpenBabel12OBDescriptor14GetStrin).

i have tried with different version of mysql from 5.5 until 5.7.

it is several days i am trying to solve problem …

"make" command run successfully of course with one warning:

Which version of Open Babel are you using?

thanks for your consideration; I used openbabel 2.3.2 ( installed with brew )

finally the problem solved. in fact it was path finding problem. I changed mysql version to 5.7 also put openbabel libs in usr/local/opt/. SELECT MYCHEM_VERSION() return true version but running other commands return null. for example:

mysql> SELECT EXACTMASS(SMILES_TO_MOLECULE('c1ccccc1'));

SELECT EXACTMASS(SMILES_TO_MOLECULE('c1ccccc1'))

+-------------------------------------------+ | EXACTMASS(SMILES_TO_MOLECULE('c1ccccc1')) | +-------------------------------------------+ | NULL | +-------------------------------------------+ 1 row in set (0.00 sec)

mysql> select version(), mychem_version(), openbabel_version();

---

select version(), mychem_version(), openbabel_version()

+-----------+------------------+---------------------+ | version() | mychem_version() | openbabel_version() | +-----------+------------------+---------------------+ | 5.7.11 | 0.9.3 | 2.3.2 | +-----------+------------------+---------------------+ 1 row in set (0.00 sec)

Thanks;

To whom it may concern, openbabel could n`t link; so reinstalling openbabel solved the link problem;
