【转帖】unresolved G-pdesc Linking Dll Libs
 

unresolved g_pdesc linking dll libs
unresolved g_pdesc linking dll libs
building the test app odamfcappdll works fine. but when i try to link my own app with dll libs (v. 1.10) i get lots of classxxxx::g_pdesc unresolved (see below). what should i check out in my build setup?
i have these defines active when i compile:
#define _toolkit_in_dll_
#define oda_db_exports
#define odafirst_dll_exports
#define odw_ge_exports
#define oda_br_exports
-rune
utldxf.lib(exodstorage.obj) : error lnk2001: unresolved external symbol "public: static class odrxclass * odrxclass::g_pdesc" (?g_pdesc@odrxclass@@2pav1@a)

check if you forgot to link with dd_root library.

i have dd_root_dll.lib in the link file.
my hunch is that the reference to...
"public: static class odrxclass * everyclassintoolkit::g_pdesc"
...is generated incorrectly at compile time. it is generated to reference a e.g. a non-dll implementation of the function. is there any defines or compile flags that controls how this function reference is layed out in the code?

you shouldn't define
#define oda_db_exports
#define odafirst_dll_exports
#define odw_ge_exports
#define oda_br_exports
these symbols in your project.
btw, odamfcappdll doesn't define them.
sincerely yours,
george udov

removing these defines proved to be significant.
it builds correctly now!

hi,
i have the same problem, but i don't use this defines...

i have only remove the static libs and try to use the dynamic libs.
