From 536ed76d5a69d8e3c0e247d6557f5942818cb253 Mon Sep 17 00:00:00 2001 From: grischka Date: Tue, 4 Apr 2017 08:34:52 +0200 Subject: tccgen/win32: let __declspec(dllimport) imply extern Also, retain storage qualifiers in type_decl, in particular also for function pointers. This allows to get rid of this very early hack in decl() type.t |= (btype.t & VT_STATIC); /* Retain "static". */ which was to fix the case of int main() { static int (*foo)(); ... Also: - missing __declspec(dllimport) is an error now - except if the symbol is "_imp__symbol" - demonstrate export/import of data in the dll example (while 'extern' isn't strictly required with dllimport anymore) - new function 'patch_storage()' replaces 'weaken_symbol()' and 'apply_visibility()' - new function 'update_storage()' applies storage attributes to Elf symbols. - put_extern_sym/2 accepts new pseudo section SECTION_COMMON - add -Wl,-export-all-symbols as alias for -rdynamic - add -Wl,-subsystem=windows for mingw compatibility - redefinition of 'sym' error for initialized global data --- win32/examples/dll.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'win32/examples/dll.c') diff --git a/win32/examples/dll.c b/win32/examples/dll.c index 4c1d8ce..052a056 100644 --- a/win32/examples/dll.c +++ b/win32/examples/dll.c @@ -4,9 +4,10 @@ // #include -#define DLL_EXPORT __declspec(dllexport) -DLL_EXPORT void HelloWorld (void) +__declspec(dllexport) const char *hello_data = "(not set)"; + +__declspec(dllexport) void hello_func (void) { - MessageBox (0, "Hello World!", "From DLL", MB_ICONINFORMATION); + MessageBox (0, hello_data, "From DLL", MB_ICONINFORMATION); } -- cgit v1.3.1
