Dark_LanternHey09:35
Dark_LanternI am having trouble running shogun from source09:35
Dark_LanternWhile it is compiling normally09:35
Dark_Lanternwhen I run the minimal.cpp program I get undefined reference errors09:35
wikingmmm09:36
wikingmaybe it doesn't find the location where the lib is installed09:36
Dark_LanternYes09:37
Dark_LanternEven pkg-config can't find the shogun libs09:37
wikinghow do you run ./configure?09:37
Dark_LanternSo what mistake am I making in the installation?09:38
Dark_LanternYes, that was the first thing I did09:38
wikingbut what's your full ./configure command looks like?09:41
wikinghow do you run it09:41
wiking?09:41
wikingif you just run simply ./configure09:41
wikingthen make and make install09:41
wikingthen your shogun libraries should be under /usr/local/lib09:42
wikingcheck it if that's right09:42
