Re: [hwloc-users] Building hwloc on Cray with /opt/cray/craype/2.5.4/bin/cc
I think you are mixing hwloc libraries here. CPUType was removed a while ago (except on Solaris). And CPUVendor was widely added later. My feeling is that your lstopo uses a recent libhwloc while your test program uses an old one.

Re: [hwloc-users] Building hwloc on Cray with /opt/cray/craype/2.5.4/bin/cc
configure seems to have detected ffsl() properly, but it looks like our ffsl() redefinition gets enabled anyway, and conflicts with the system-wide one. Does it help if you comment out line #66 of include/private/misc.h ? extern int ffsl(long) __hwloc_attribute_const; Brice Le 05/01/2017 13:52, Xavier LACOSTE a écrit : > > Hello Brice, > > > > I attached the files. > > > > I could build hwloc and link with it using the default (gcc) compiler. > > But If I use gcc to build the library I can link with gcc/icc/pgcc but > not with cc from cray. > > > > Thanks, > > > > XL. > > > > > > *De :*Brice Goglin [mailto:brice.gog...@inria.fr] > *Envoyé :* jeudi 5 janvier 2017 12:50 > *À :* Xavier LACOSTE > *Cc :* Hardware locality user list > *Objet :* Re: [hwloc-users] Building hwloc on Cray with > /opt/cray/craype/2.5.4/bin/cc > > > > Hello Xavier > Can you send the /usr/include/string.h from that cray machine, your > config.log and include/private/autogen/config.h from the hwloc build > directory? > Do you get the same error if building from the default compiler > instead of /opt/cray/craype/2.5.4/bin/cc? > thanks > Brice > > Le 05/01/2017 12:31, Xavier LACOSTE a écrit : > > > > Hello, > > > > I’m trying to build hwloc on a cray machine with cray > compiler :/opt/cray/craype/2.5.4/bin/cc > > > > I get the following error : > > $> CC=cc ./configure --prefix=$PWD-cc-install > > $> make > > Making all in src > > make[1]: Entering directory `/home/j0306818/xavier/hwloc-1.11.5/src' > > CC bitmap.lo > > CC-147 craycc: ERROR > > Declaration is incompatible with "int ffsl(long)" (declared at > line 526 of > > "/usr/include/string.h"). > > > > > > Total errors detected in bitmap.c: 1 > > make[1]: *** [bitmap.lo] Error 1 > > make[1]: Leaving directory `/home/j0306818/xavier/hwloc-1.11.5/src' > > make: *** [all-recursive] Error 1 > > > > Do you have any idea of what I am doing wrong ? > > Is this a known issue ? > > > > Another secondary question : > > > > Hwloc builds correctly with gcc compiler but the CPUVendor field > is not available using this code : > > > > #include > > > > int main(int argc, char *argv[]) > > { > > hwloc_topology_t topo; > > hwloc_obj_t obj; > > int err; > > int i; > > char obj_str[2048]; > > char attr_str[2048]; > > > > /* initialize a topology context */ > > err = hwloc_topology_init(&topo); > > assert(!err); > > > > /* insert optional topology configuration here */ > > > > /* build the topology created and configured above */ > > err = hwloc_topology_load(topo); > > > > /* play with the topology here */ > > obj = hwloc_get_obj_by_type(topo, HWLOC_OBJ_PACKAGE, 0); > > fprintf(stdout, "CPU_Vendor : %s \n", > hwloc_obj_get_info_by_name(obj,"CPUVendor")); > > hwloc_obj_type_snprintf(obj_str, 2048, obj, 1); > > hwloc_obj_attr_snprintf(attr_str,2048, obj, " | ", 1); > > fprintf(stdout, "%s : %s\n", obj_str, attr_str); > > > > /* terminate this topology context */ > > hwloc_topology_destroy(topo); > > > > return 0; > > } > > > > Am I using the correct code to retrieve the CPUVendor ?

What output do you get?

Hello Xavier Can you send the /usr/include/string.h from that cray machine, your config.log and include/private/autogen/config.h from the hwloc build directory? Do you get the same error if building from the default compiler instead of /opt/cray/craype/2.5.4/bin/cc? thanks Brice Le 05/01/2017 12:31, Xavier LACOSTE a écrit : > > > > Hello, > > > > I’m trying to build hwloc on a cray machine with cray > compiler :/opt/cray/craype/2.5.4/bin/cc > > > > I get the following error : > > $> CC=cc ./configure --prefix=$PWD-cc-install > > $> make > > Making all in src > > make[1]: Entering directory `/home/j0306818/xavier/hwloc-1.11.5/src' > > CC bitmap.lo > > CC-147 craycc: ERROR > > Declaration is incompatible with "int ffsl(long)" (declared at line > 526 of > > "/usr/include/string.h"). > > > > > > Total errors detected in bitmap.c: 1 > > make[1]: *** [bitmap.lo] Error 1 > > make[1]: Leaving directory `/home/j0306818/xavier/hwloc-1.11.5/src' > > make: *** [all-recursive] Error 1 > > > > Do you have any idea of what I am doing wrong ? > > Is this a known issue ? > > > > Another secondary question : > > > > Hwloc builds correctly with gcc compiler but the CPUVendor field is > not available using this code : > > > > #include > > > > int main(int argc, char *argv[]) > > { > > hwloc_topology_t topo; > > hwloc_obj_t obj; > > int err; > > int i; > > char obj_str[2048]; > > char attr_str[2048]; > > > > /* initialize a topology context */ > > err = hwloc_topology_init(&topo); > > assert(!err); > > > > /* insert optional topology configuration here */ > > > > /* build the topology created and configured above */ > > err = hwloc_topology_load(topo); > > > > /* play with the topology here */ > > obj = hwloc_get_obj_by_type(topo, HWLOC_OBJ_PACKAGE, 0); > > fprintf(stdout, "CPU_Vendor : %s \n", > hwloc_obj_get_info_by_name(obj,"CPUVendor")); > > hwloc_obj_type_snprintf(obj_str, 2048, obj, 1); > > hwloc_obj_attr_snprintf(attr_str,2048, obj, " | ", 1); > > fprintf(stdout, "%s : %s\n", obj_str, attr_str); > > > > /* terminate this topology context */ > > hwloc_topology_destroy(topo); > > > > return 0; > > } > > > > Am I using the correct code to retrieve the CPUVendor ?
