(hope u get what i mean.) -----thats it for the compile next.. on the research i did.. i found that .a means nothing but an archive of .o files...so i could extract the .o files from the archive so are there any options that i could give the ./configure script or the makefile to include these .o files while linking... u must have noticed by now, that these libs are not created/compiled by me. <IMG SRC="cid:1138963455.2720.6.camel@nextbitcpu.com" ALIGN="middle" ALT=";)" BORDER="0">. anyways plz help me some more <IMG SRC="cid:1138963516.2720.8.camel@nextbitcpu.com" ALIGN="middle" ALT=":)" BORDER="0"> . awaiting ur replies. bye take care sameer On Thu, 2006-02-02 at 13:53 +0100, Stefan Kost wrote: <BLOCKQUOTE TYPE=CITE> <PRE> Hi Sameer, so the libs are your own. In this case forget the pkg-config stuff for now (that is used for third party stuff). All you need is to add something lib '-lalgorithm -lmemory' to your LDFLAGS.
