visual studio - Find out whether a lib requires static or dynamic runtimes -

whenever link static libraries visual c++ project have create sure value runtime library of project matches value used compile library. if illustration library compiled alternative static runtimes , seek compile project dynamic runtimes linker throw error.

obviously linker has way of determining whether library compiled static or dynamic runtimes. wondering if there command line tool takes library , can straight tell me runtimes used during creation?

dumpbin /directives friend:

c:\jm>type 08.cpp int main() { } c:\jm>cl /nologo /c /mt 08.cpp 08.cpp c:\jm>dumpbin /nologo /directives 08.obj dump of file 08.obj file type: coff object linker directives ----------------- /defaultlib:libcmt /defaultlib:oldnames summary 60 .debug$s 2f .drectve 7 .text$mn c:\jm>

note /defaultlib:libcmt under "linker directives." linker directive injected object when compile /mt (static release crt). /mt, /mtd, /md, , /mdd linker options cause different runtime libraries dragged in. see the documentation details.

a library collection of objects, can utilize dumpbin /directives on lib file directives contained in each object in library. note it's possible (though quite uncommon) different objects in single static library compiled different runtime library options.
