[Mono-devel-list] Problem in compiling Class library in Windows while using SecurityPermissionAttr

Hmmm... my guess is that by Windows you mean Microsoft's CSC under Windows
(and not Mono's MCS) right ?

Yes that's an old "problem".

It was.

Well when/if you get a problem when building anything Mono related in
[insert your current setup] way (i.e. not using the Makefile supplied in
Mono) then you should take the time to read them. Like Hari said: "RTFM,
read the fine makefile, that is :-)"

In this case you'll see that CSC 7.x (fx 1.x) requires something special to
compile mscorlib (note: this problem disappeared with CSC 8.x as the
security attributes are now encoded differently). You can see this in
/mcs/class/corlib/Makefile in the fourth line.

export __SECURITY_BOOTSTRAP_DB$=(topdir)/class/corlib

P.S. Look at the mailing-list archives if you want to know the "why".
