I tried building the graph library and the graph examples with bjam. I am using gcc 3.2.1 on Solaris 2.8. The library seemed to build successfully but did have warnings. The examples failed to build complaining that it could not find the dependent graph library which seems to be a problem with my LD_LIBRARY_PATH or something like that. The build outputs for both cases are given below. I did not do any customizing for either of these builds. My cmd line was bjam "-sTOOLS=gcc" Any help is appreciated. Thanks in advance Vik Anantha <GRAPH EXAMPLES BEGIN> unknown dependent target <libs!graph!build>liblibbgl-viz.a </GRAPH EXAMPLES END> <BGL BUILD BEGIN> ...patience... ...found 437 targets... ...updating 11 targets...
