What happened to __TRY?

[Michael Ost]

Hi all,

When I upgraded wine-develfrom 1.0 to 1.1.7, my winelib app that uses 
__TRY no longer links. It complains that RtlUnwind cannot be found. I 
can see that RtlUnwind was added to wine/exception.h, but I am not sure 
how to fix it.

I tried adding -lntdll and -lwine to the link command line but it didn't 
help. Any suggestions?

Thanks! ... mo

PS: Here's the linker line I am using and the error returns...

Have you tried linking to kernel32 too?

Yes, you need to link to ntdll. Linking to libwine shouldn't be
necessary. Please post the command line you are using and errors you
are getting even when you link to ntdll.

This should be fixed in git now, Alexandre added C++ wrappers for
exported APIs into public Wine .h files.

I tried linking to ntdll and kernel32, but same result. Unless I am 
linking in the wrong way? Command line and result are below.

BTW - I thought that wineg++ linked in ntdll and kernel32 automatically...?

Thanks! ... mo
