Hey,
So a big win last night: after installing libgit2 from ports, was able to
build and run MOnoDevelop from MonoDevelop. I patched
file:///usr/home/rhaley/git/monodevelop/main/external/libgit2sharp/LibGit2S=
harp/Core/NativeDllName.cs:
public const string Name =3D "/usr/local/lib/libgit2.so";
and had to make some other changes and remove an NFactory test. I'll try
to reproduce it and create a patch some time later. Yay!
The REAL error I am trying to track down occurs when adding or removing a
new project to a solution. I get a general I/O error. I've tracked it down
to
main/src/core/MonoDevelop.Core/MonoDevelop.Core/FileService.cs
at line 572 a Syscall.rename is attempted and the error code is not handled
in the case statement. I am getting
Mono.Unix.Native.Errno.EXDEV (value 18)
Which I tracked down here:
http://docs.go-mono.com/index.aspx?link=3DF%3AMono.Unix.Native.Errno.EXDEV
"Cross-device link. A hard link to a file on another file system was
attempted."
Values are:
sourceFile "/tmp/tmp51cc4b8d.tmp"
destFile
"/usr/home/rhaley/Projects/Objektiv2/Objektiv/Objektiv/Objektiv.sln"
mount reveals the following:
tank/tmp on /tmp (zfs, local, nosuid, nfsv4acls)
tank/usr/home on /usr/home (zfs, local, nfsv4acls)
tank/usr/home/rhaley on /usr/home/rhaley (zfs, local, nfsv4acls)
however, I can manuall mv the file.
Any thoughts? I am guessing that the syscall.rename is doing something
other than an mv and zfs doesn't like it. Or conversly, zfs is doing
something funky and the mono wrapper library doesn't like it?
Anyway, all input welcome. Much thanks!
Russell
