Hello there
Is there a way to link 'libcudart.so' and 'libnvidia-ml.so' solely to
their respective plugin .so files, not the main libraries/executables?
This is the './configure' line i'm using:
./configure --enable-shared --enable-static --enable-pci --enable-cuda
--enable-nvml --enable-cairo --enable-plugins='nvml,cuda'
Software details:
- Centos 6.5
- gcc 4.4.7
- hwloc 1.10.1
- cuda 6.5-14
- nvidia driver 340.29
Hello
Your configure line should do exactly what you want, and that's the
whole point of plugins:

If ldd shows libcudart and libnvidia-ml dependencies in libhwloc.so, you
may use "make V=1" to verify the link command-line that built these
libs, and then find the relevant link line/options in Makefile, and then
in Makefile.am
Hi Brice, thanks for answering.
Strangely, xml_libxml and pci works fine as plugins, but nvml and cuda
not. I had no trouble making the 'pci' and 'xml_libxml' plugins link to
their respective libraries, leaving 'libhwloc.so' alone, but no dice
with 'nvml' or 'cuda'.
I've managed to find the offending link line:
========================================================================
libtool: link: gcc -shared -fPIC -DPIC .libs/topology.o

-o .libs/libhwloc.so.5.6.1
=========================================================================
'-L/usr/local/cuda-6.5/lib64 -lcudart -L/usr/src/gdk/nvml/lib
-lnvidia-ml' should not be here, right ?
Inside 'src/Makefile', the commenting mechanism of
'hwloc_xml_libxml_la_*', 'hwloc_cuda_la_*', 'hwloc_nvml_la_*',
'hwloc_pci_la_*' seems to be working fine ( uncommenting when set to be
made as plugins ).
Any clues ?
