Hi Amitvikram,

Could you send us your CMakeCache.txt file from your build directory and the output from running:
make VERBOSE=1
for both cases.

In the case of using ThirdParty LAPACK, it seems to not be linking to it. Probably you should be using vendor-supplied libraries if possible though so better if ee can get those working.

Thanks,
Chris

Hi Jeremy,

I'm actually trying to build nektar++ on a BGQ cluster similar to Mira.

I'm trying to build nektar++-4.4.1 and the system lapacek version is 3.4.2

Sincerely,

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.

Thanks,

Jeremy

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,
