Re: [HTCondor-users] virtualenv, pip and htcondor (python)

[L Kreczko <L.Kreczko@xxxxxxxxxxxxx>]

Hi John, hi Brian,

Thanks for the answers. After a bit of fiddling I ended up with this set:

cmake -DPROPER:BOOL=FALSE -DCLIPPED:BOOL=TRUE -DWITH_BLAHP:BOOL=FALSE -DWITH_COREDUMPER:BOOL=FALSE \

   -DWITH_CREAM:BOOL=FALSE -DWITH_DRMAA:BOOL=FALSE -DWITH_GLOBUS:BOOL=FALSE -DWITH_GSOAP:BOOL=FALSE \

   -DWITH_HADOOP:BOOL=FALSE -DWITH_LIBVIRT:BOOL=FALSE -DWITH_LIBXML2:BOOL=FALSE -DWITH_UNICOREGAHP:BOOL=FALSE \

   -DWITH_VOMS:BOOL=FALSE -DWITH_BOINC:BOOL=FALSE -DWITH_KRB5:BOOL=FALSE -DWITH_LIBCGROUP:BOOL=OFF\

   -DWITH_GANGLIA:BOOL=OFF -DWITH_CAMPUSFACTORY:BOOL=OFF -DWITH_BOSCO:BOOL=OFF -DWANT_GLEXEC:BOOL=OFF \

   -DUW_BUILD:BOOL=TRUE -D_VERBOSE:BOOL=TRUE -DBUILDID:STRING=UW_development -DCMAKE_INSTALL_PREFIX:PATH=${PWD}/release_dir "$@"

However, since I turn off KRB5 an error occurs:

/home/vagrant/workspace/htcondor/src/condor_io/condor_auth_ssl.cpp: In static member function âstatic bool Condor_Auth_SSL::Initialize()â:

/home/vagrant/workspace/htcondor/src/condor_io/condor_auth_ssl.cpp:107:7: error: âCondor_Auth_Kerberosâ has not been declared

 if ( Condor_Auth_Kerberos::Initialize() == false ||

   Â^

If I allow for KRB, the compilation fails at DAG:

[ 74%] Linking CXX executable condor_submit_dag

+ many more 'undefined reference'.

Is there a way to disable DAG? Essentially, I just want the python-bindings :)

And just as I said that, IÂ

cd src/python-bindings/

make

and end up with htcondor.so and classad.so!

Well, that was easy ;)

Starting from fresh, the python-bindings also compile

Â- src/classad

Â- src/condor_utils

Next step is to make the compiled libraries work with the installed ones (e.g import the module):

python -c 'import htcondor'Traceback (most recent call last):

 File "<string>", line 1, in <module>

ImportError: /home/vagrant/workspace/htcondor/src/python-bindings/libcondor_utils_8_5_9.so: undefined symbol: _ZN7classad19ClassAdJsonUnParser7UnparseERNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEPKNS_7ClassAdERKSt3setIS6_NS_12CaseIgnLTStrESaIS6_EE

BTW: 'import classad' works out-of-the-box'

For the setup.py there are two approaches:

Â1) C++ Extension:Âhttps://docs.python.org/2.7/extending/building.html

Â2) Using DistutilsInstall:Âhttp://stackoverflow.com/questions/1754966/how-can-i-run-a-makefile-in-setup-py

Not experienced with either, suggestions are welcome.

Cheers,

Luke

I suspect you'll need to pick apart ./configure_uw and aggressively disable cmake flags. For example, the error you reference on 16.04 is due to a failure building a unit test. You can do without those!

All variants of the compilation should result in a compatible protocol layer. However, if you disable some of the security libraries (think Globus, Kerberos), the security negotiation might fail.
