On Debian testing, upgarding 10.1.beta7 to 10.1.beta8 and running prestlong gave a raft of new failures :

if you used systemwide sparsesuite (libcholmod is there) and updated
it, you'd need to rebuild everything that uses it.
Specifically, only cvxopt, it seems.

if you used systemwide sparsesuite (libcholmod is there) and updated
it, you'd need to rebuild everything that uses it.
Specifically, only cvxopt, it seems.

Indeed : recompiling after reconfigiring locate was inefficient.

I’m stuck : both cvxopt and suitesparse are installed systemwide :

And the effective installation seems to conform :

charpent@zen-book-flip:/usr/local/sage-10$ ls -l /usr/lib/x86_64-linux-gnu/libcholmod* -rw-r--r-- 1 root root 1807448 16 juil. 19:13 /usr/lib/x86_64-linux-gnu/libcholmod.a lrwxrwxrwx 1 root root 15 16 juil. 19:13 /usr/lib/x86_64-linux-gnu/libcholmod.so -> libcholmod.so.4 lrwxrwxrwx 1 root root 19 16 juil. 19:13 /usr/lib/x86_64-linux-gnu/libcholmod.so.4 -> libcholmod.so.4.0.4 -rw-r--r-- 1 root root 1226816 16 juil. 19:13 /usr/lib/x86_64-linux-gnu/libcholmod.so.4.0.4 charpent@zen-book-flip:/usr/local/sage-10$ find . -iname "libcholmod*" charpent@zen-book-flip:/usr/local/sage-10$

I do not understand why Sage looks for libcholmod.so.3 :

File "src/sage/matrix/matrix2.pyx", line 12741, in sage.matrix.matrix2.Matrix.cholesky Failed example: A.cholesky() Exception raised: Traceback (most recent call last): File "/usr/local/sage-10/src/sage/doctest/forker.py", line 709, in _run self.compile_and_execute(example, compiler, test.globs) File "/usr/local/sage-10/src/sage/doctest/forker.py", line 1144, in compile_and_execute exec(compiled, globs) File "<doctest sage.matrix.matrix2.Matrix.cholesky[60]>", line 1, in <module> A.cholesky() File "sage/matrix/matrix_double_sparse.pyx", line 197, in sage.matrix.matrix_double_sparse.Matrix_double_sparse.cholesky from cvxopt import cholmod, spmatrix, matrix as cvxopt_matrix ImportError: libcholmod.so.3: cannot open shared object file: No such file or directory

configure does not seem to be able to force a local installation of cvxopt.

Hints ?

Do you need the logs ? I have to post differently (Googne groups doe not accept attachments…).

cvxopt may be installed systemwide, but Sage does not use Python packages from the system.

"make cvxopt-uninstall cvxopt" should fix the problem

Indeeed. Except that you neeed make cvxopt-uninstall ; make cvxopt… Thank you Matthias !

The cvxopt errors disappeared. Hwever, I still have

• a few permanent errors :
