Wireshark-dev: Re: [Wireshark-dev] Do Windows compilers require WS_VAR_IMPORT in .h files

Hello,
I'm working on building wireshark with gcc with -fvisibility=hidden. This
will mostly mimic the behaviour already on Windows. The gcc attribute
to change the visibility causes errors when used in .h files (well, in
declarations without a the object).
I have replaced WS_VAR_IMPORT with extern in .h files. Can someone on Windows
please test whether this still works?
Hi Jörg,
it fails with the following errors (MSVC2010EE 32 bits):
