If you don't do anything at all, the default behavior is "METHODS='dbg devel opt'", which simultaneously builds versions of libmesh with ridiculous levels of debugging enabled, sane levels of debugging enabled, and no debugging enabled, respectively. >> 2, It outputs an error when I install libmesh: "attempted static link with >> libstdc++.so", how can I link this lib correctly? We never add this library to the link line ourselves - it would be redundant since we use C++ compilers to link. We do pull in linker options from other packages, like PETSc; you can examine configure logs to see which is including that entry. By the way - is the text in quotation marks an exact quotation, or a paraphrase? It looks like the latter, but paraphrasing compiler error messages is never a good idea; Google doesn't work well that way. --- Roy ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
