[gmx-developers] Linking error while using external lapack/blas

[Béla Voß]

Hi,

I noticed that running the configure script with the 
--with-external-blas or --with-external-lapack options will lead to a 
linking error during the make procedure because the configure script 
does not check for those libraries and does not add an entry to the LIBS 
variable in the makefiles. This applies both to the 4.0.7 version and to 
master branch.

I wanted to ask whether this is the desired behaviour in order to 
enforce the user to choose the right libraries.
Otherwise i.e. if the configure script should check for all necessary 
dependencies (what is in my opinion more correct) this could be fixed by 
adding the checks to configure.ac (see attachment)

Kind regards,
Béla
