This is because Consts.cs isn't in the build script.  You can

add ../../build/common/Consts.cs to

mcs/tools/monodoc/monodoc.dll.sources and the Consts type will be


Thanks for this tip !

No.  The AssemblyVersionAttribute doesn't say what runtime version it

targets.  It specifies the version of the assembly itself (monodoc.dll

in this case).

well, that's what I figured out at the end.

Since we were compiling the assembly twice with the same version number

each time, gacutil was installing both of them into the same directory.

If the separate builds had different version numbers, they'd be

installed into different GAC directories.  Hence using Consts.FxVersion

would be *a* fix for this.

Thanks again, so the whole idea is to separate the two monodoc.dlls so the
2.0 one doesn't get overwritten with the 4.0 one.

But this is, in fact, the wrong compiler.  It's the wrong compiler

because monodoc (the app) was built against gmcs (see mono-tools).  Thus

when it runs, it'll be started as a 2.0 app, which won't be able to add

4.0-specific members, which is *exactly* the scenario you're in.

   2. cd mcs/tools/monodoc

   3. make PROFILE=net_2_0

   4. make PROFILE=net_2_0 install

Thanks for this tip too.

A longer term fix is to make the AssemblyVersionAttribute conditional on

the framework version (e.g. use Consts.FxVersion).

here is what I did:

   1. changed AssemblyVersionAttribute to Consts.FxVersion.
   2. in mcs/tools/monodoc
      1. make PROFILE=net_2_0 && sudo make install PROFILE=net_2_0
      2. make PROFILE=net_4_0 && sudo make install PROFILE=net_4_0

now there is two folders in mono/gac/monodoc, a 2.0.0* one and a 4.0.0* one,
I think the latter has no importance and actually is not used, but it won't

now monodoc runs fine but there is something weird:
I can't see gtk sharp libraries documentation, maybe I have to recompile gtk
sharp (and hence its documentation) again. I will try and report back,  I'm
doing an Electronics project now, which I hate :), so I may reply late.

Big Thanks !
