Hi Amitvikram, Can you provide some further details of the problem you're encountering. Specifically, can you confirm what platform (including version) you're building on, and if Linux, which I assume is the platform you're using, which distribution. Can you also confirm what version of Nektar++ you're trying to build, and the version of the system Lapack distribution that you're using.

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?
