Bug ID: 102193
Summary: DLL linking with a external referenced DLL
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: arsoftware25 at gmail dot com
Target Milestone: ---
Hi Corina
just figured out that a .def file in a dll may export function from a dll that
is referenced in the compilation stage like this:
gcc file.c external.dll def.def -o out.dll
if in the def.def it has a function that is in the file.c and also available in
external.dll it may generate an invalid out.dll
I don't know but this looks like a problem in gcc that need to be fixed, spend
one hour modifying my function in file.c and it was linking with external.dll
then I commented the function inside file.c and saw the compilation stage
finished without a link error
if it is a GCC feature then a warning about expernal DLL linkage could help a
lot when the function exported is inside an external DLL
hope to have explained it in an easy way
Ricardo
