Hi Csaba, so I am using a cmake and it is of the format: set(LAPACK_LIB "/usr/lib/liblapack.so") set(LAPACK_LIB "/usr/lib/liblapacke.so") set(BLAS_LIB "/usr/lib/libblas.so") for my ubuntu system, which I changed it to: set(LAPACK_LIB "/usr/lib/liblapack.a") set(BLAS_LIB "/usr/lib/libblas.a") for the cygwin.If I set the set(LAPACK_LIB "/usr/lib/liblapacke.a") it complains that it doesn't exist, since as you also said this package doesn't exist in Cygwin. So in my code I am calling at some point functions like the LAPACKE_zlange and there is the issue. I guess I cannot use them in Cygwin, and I will have to change it to FORTRAN calls

Hi Constantinos, On Sat, Nov 18, 2017 at 5:24 PM, Constantinos Zekios wrote:Hello everybody! I recently installed cygwin trying to compile my cpp code (it is build under linux) under windows. I am using LAPACKE (the c wrapper to run all the lapack libraries) in my code, but it seems that I am not able to install the packages in cygwin. I have installed lapack, as well as blas. Does anybody know how to install liblapacke.a, liblapacke.dll.a? The errors that I am getting are of the form: undefined reference to 'LAPACKE_zlange'.That sounds like the linker complaining about not finding a symbol, *not* about a missing library file. If that's the case, installing libraries will not help you. Just as well, because there's no Cygwin package containing liblapacke.a : https://cygwin.com/cgi-bin2/package-grep.cgi?grep=liblapacke&arch=x86_64 (Found 0 matches for liblapacke) What was the linker invocation (command line) that generated the error message?
