Hi maintainer
Elpa FTBFS on Ubuntu builders as it fails the blacs link test in
configure with the following output:
configure:6376: checking for library containing blacs_gridinit
configure:6394: mpif90 -o conftest -g -O2 -ffree-form
-lblacsCinit-openmpi -lblacs-openmpi -lscalapack-openmpi conftest.f
-llapack -lblas >&5
/tmp/ccgbFmtZ.o: In function `MAIN__':
/build/buildd/elpa-2013.11.008/conftest.f:2: undefined reference to
`blacs_gridinit_'
collect2: error: ld returned 1 exit status
configure:6394: $? = 1
configure: failed program was:
| program main
| call blacs_gridinit
| end
...
configure:6411: result: no
configure:6421: checking whether we can link a program with a blacs lib
configure:6423: result: no
configure:6427: error: could not link with blacs: specify path
It seems the linker in Ubuntu is much stricter than the one in Debian.
I was able to get it to build successfully by reversing the order of the
blacs and scalapack libraries, and inserting them after 'conftest.f' (as
LIBS) instead of before 'conftest.f' (as LDFLAGS), as follows:
mpif90 -o conftest -g -O2 -ffree-form conftest.f -llapack -lblas
-lscalapack-openmpi -lblacs-openmpi -lblacsCinit-openmpi
Please consider the attached patch.
Regards
Graham

+Description: Add blacs libraries as LIBS instead of LDFLAGS
+ This patch fixes a FTBFS in Ubuntu when configure checks for blacs
+ and scalapack libraries.
+ .
+ This works in Debian, but fails in Ubuntu:
+ mpif90 -o conftest -g -O2 -ffree-form -lblacsCinit-openmpi
+ -lblacs-openmpi -lscalapack-openmpi conftest.f -llapack -lblas
+ .
+ While this works in Ubuntu:
+ mpif90 -o conftest -g -O2 -ffree-form conftest.f -llapack -lblas
+ -lscalapack-openmpi -lblacs-openmpi -lblacsCinit-openmpi
