Build issue
Kmanolo opened this issue · comments
Hi,
I have downloaded pyql and Quantlib to a new Linux Mint system ( Linux Mint 17.2 cinnamon 64bit).
I am unable to build pyql with errors similar to 103.
The quantlib has build fine and I can run the examples fine. Please also note i am using Cython 0.23.4.
Any help is much appreciated, the error is attached below :

@Kmanolo This is a known issue. Either you have to downgrade cython to the same version used on master or patch the code to work with the latest Cython.
@dpinte thanks fro your reply. I misunderstood that its ok with Cython > 0.20. What would I have to patch to get it working with newer Cython ? Sth I missed on the previous issue ?
Many thanks!
@Kmanolo I haven't had the time to investigate the issue with the newest Cython. It seems the Period vs TimeUnit declarations in the pxd files should be reworked... You should look into quantlib/time/date.pyx and quantlib/time/_date.pxd
