Can't find Suitesparse

[michaels...@gmail.com]

I managed to build Suitesparse (using Clang). However, ceres does not seem to recognize it.

-- A library with BLAS API found.

-- Found LAPACK library: /usr/lib/liblapack.so;/usr/lib/libf77blas.so;/usr/lib/libatlas.so

-- Found BLAS library: /usr/lib/libf77blas.so;/usr/lib/libatlas.so

-- Building without SuiteSparse.

-- Building without CXSparse.

   ===============================================================

   Compiling without any sparse library: SuiteSparse, CXSparse 

   & Eigen (Sparse) are all disabled or unavailable.  No sparse 

   linear solvers (SPARSE_NORMAL_CHOLESKY & SPARSE_SCHUR)

   will be available when Ceres is used.

despite that I have (copied manually as make install did not want to do it for me)

libsuitesparseconfig.so and so on in /usr/local/lib

any suggestions? [I guess copying into /usr/local/include ?? but not sure what to call the folder]

Cheers, Mike

I am using 4.5.5

the output I get after running make install is (partially):

( cd Lib ; make install )

make[2]: Entering directory '/opt/suitesparse/SuiteSparse/SPQR/Lib'

make[2]: Nothing to be done for 'install'.

make[2]: Leaving directory '/opt/suitesparse/SuiteSparse/SPQR/Lib'

make[1]: Leaving directory '/opt/suitesparse/SuiteSparse/SPQR'

There should be more output from Ceres about why SuiteSparse was disabled, that would only be shown on the first configure though, when SUITESPARSE will be ON by default until something turns it OFF.  Thereafter when Ceres is re-configured it will be with SUITESPARSE=OFF and the log output won’t be shown as find_package(SuiteSparse) will not be being called.

You can force the error output to reappear by configuring Ceres with:

cmake -DSUITESPARSE=ON <PATH_TO_CERES_SOURCE_DIR>

what does the Ceres CMake output say then?

Thanks Alex.  This makes it clear. It misses the headers. I will copy those manually as well then.

I moved my headers into /usr/local/include/suitesparse and it is almost ok. However, I now have one missing header

- Found CHOLMOD library: /usr/local/lib/libcholmod.so

-- Found CHOLMOD header in: /usr/local/include/suitesparse

-- Found SuiteSparseQR library: /usr/local/lib/libspqr.so

-- Failed to find SuiteSparse - Did not find SUITESPARSEQR header (required SuiteSparse component).

-- Found SuiteSparse_config library: /usr/local/lib/libsuitesparseconfig.so

-- Found SuiteSparse_config header in: /usr/local/include/suitesparse

I do seem to have SuiteSparseQR_C and SuiteSparseQR_definitions.h there. 

RBio.h                       umfpack_report_numeric.h

cholmod_check.h        SuiteSparse_config.h         umfpack_report_perm.h

cholmod_cholesky.h     SuiteSparseQR_C.h            umfpack_report_status.h

cholmod_complexity.h   SuiteSparseQR_definitions.h

Not sure what the problem is. May be the latest SuiteSparse updated file names? How can I figure out which file it is looking for?

Best, Mike
