<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">2011/4/12 Kapoor, Nitin <Nitin.Kapoor@sensis.com>:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">> Do you know where it would come from ("/opt/csw/gcc4/lib/libstdc++.so") ? The only place where I have to pass the /opt/csw/gcc4/lib is when I configure a package.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">Two ideas about the libstdc++.so reference:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">- it's volunteered by the build system</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">- it comes from a *-config command of one of the dependencies</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">The *-config commands can return ldflags which are later used in the</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">build process. For example:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">$ libpng-config --ldflags</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">-L/opt/csw/lib -lpng12</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">Try looking at the config.log file of your build, maybe it'll contain</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">some hints. If not, look at all the dependencies, locate their</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">*-config scripts and see if they return libstdc++.so if you call them</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">with e.g. --libs or --ldflags.</FONT></SPAN></P>
