[FIXED] LNK1104 error with python setup.py build

Issue

I have built Quantlib on Windows using Visual Studio 2017 and want to build Quantlib-SWIG for Python.

However, I have LNK1104: error. Namely, after launching Command Prompt from C:\QuantLib-SWIG-1.12\Python directory I receive this error:

 fatal error LNK1104: cannot open file 'QuantLib-vc90-x64-mt.lib'

I saw a similar question with advise from Luigi Ballabio and KingJohnno to verify if QuantLib-vc90-x64-mt.lib file is in place & add to the path variable C:\QuantLib-SWIG-1.12.

I did the last suggestion, but I have the problem with that I have in C:\QuantLib\QuantLib-1.12\lib a QuantLib-vc141-x64-mt.lib library, i.e. not the file QuantLib-vc90-x64-mt.lib. I have created separate directory with vc141 file renamed to vc90. This did not help.

I have also read online that the problem might be with the Python specifically builded using different VS version. I have downloaded Python 2.7 builded using VS 2010 (not VS2008) and did not succeed as well.

Please see the whole terminal message here:

Solution

python setup.py build worked under Python 3.6.5.
