Sorry, but I don't understand your mail. Did you saw the same problems like Adam when compiling "NativeImageBuffer.cpp"? - If yes, did you fix them by excluding the inclusion of "osSupport.hpp" ? That would be strange, because it doesn't seem to related to the problems reported until now at all. - If no, I'm totally confused... > Thanks, > Ichiroh Takiguchi > IBM Japan, Ltd. > > On 2018-11-27 02:06, Volker Simonis wrote: > > On Mon, Nov 26, 2018 at 2:16 PM Adam Farley8 <adam.far...@uk.ibm.com> > > wrote: > >> > >> Hi Volker, > >> > >> Apologies for the delay. > >> > >> I ran the contents of the file as requested (neat tip, thanks!) and I > >> discovered something: > >> > >> If jdk_internal_jimage_NativeImageBuffer.h contains this: > >> > >> ----- > >> extern "C" { > >> __attribute__((visibility("default"))) jobject JNICALL > >> Java_jdk_internal_jimage_NativeImageBuffer_getNativeMap > >> (JNIEnv *, jclass, jstring); > >> } > >> ----- > >> > >> It results in this error: > >> > >> ----- > >> blah blah "visibility" may be undeclared or ambiguous. > >> ----- > >> > >> But replacing that bit with this code: > >> > >> ----- > >> extern "C" __attribute__((visibility("default"))) jobject JNICALL > >> Java_jdk_internal_jimage_NativeImageBuffer_getNativeMap > >> (JNIEnv *, jclass, jstring); > >> ----- > >> > >> Results in no error. > >> > >> So it seems the difference between an "extern "C"" block and an inline > >> "extern"C"" is what's causing the issue. > >> > > > > Thanks for finding this out.
