Hi all, I keep having the same problem while trying to install nektar++ with regards to the Lapack libraries. When I try to use the system Lapack installation I get the following message */scinet/bgq/Libraries/lapack/lib/liblapack.so: undefined reference to `_xlfEndIO@XLF_1.0'* while when I try to install using the ThirdParty Lapack supplied with the nektar++ source directory I get the following error *../../library/LibUtilities/libLibUtilities.so.4.4.1: undefined reference to `dtpmv_'* I have a feeling these errors have been encountered by the community at large before. Could someone point out where I'm going wrong? Sincerely, -- *Amitvikram Dutta* Graduate Research Assistant Fluid Mechanics Research Lab Multi-Physics Interaction Lab University of Waterloo
