#1 Linker problem; libcolamd.a

[Samuel Fux]

Hi,

I downloaded the sources via svn co https://libgimli.svn.sourceforge.net/svnroot/libgimli/trunk libgimli and tried to compile libgimli.

For linking the required libraries, I set

export LDFLAGS='-L/cluster/apps/openblas/0.2.4_seq/x86_64/gcc_4.7.0 -lopenblas -L/cluster/apps/boost/1.51.0/x86_64/serial/gcc_4.7.0/lib64 -lboost_system -L/cluster/apps/suitesparse/4.0.2/x86_64/gcc_4.7.0/lib64 -lsuitesparseconfig -lcolamd -lcholmod -lamd -lldl'

Everything seems to compile without error but when doing an ldd -d command to check if the library is complete, it shows an undefined symbol

[sfux@brutus2 ~]$ ldd -d libgimli-0.9.so.0
linux-vdso.so.1 => (0x00007fffe4d24000)

undefined symbol: colamd_printf (./libgimli-0.9.so.0)
[sfux@brutus2 ~]$

this somehow indicates that libcolamd.a from suitesparse was not linked correctly. When linking to libgimli, I get an "undefined reference to" error shows up until libsuitesparseconfig and libcolamd are linked explicitely.

Best regards
