Hello, here is my problem: I want to install monodevelop, and to do this I have to install gtksourceview#. But this last one does not recognize gnome#: checking for GTK_SHARP... configure: error: Package requirements (gnome-sharp-2.0 >= 1.9.3) were not met: No package 'gnome-sharp-2.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GTK_SHARP_CFLAGS and GTK_SHARP_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. so I reinstalled gnome-sharp and after having entered "./configure" I have the following message: --- Configuration summary * Installation prefix = /opt/local * C# compiler: /opt/local/bin/mcs -define:GTK_SHARP_2_6 -define:GTK_SHARP_2_8 -define:GNOME_SHARP_2_16 Optional assemblies included in the build: * art-sharp.dll: yes * gnomevfs-sharp.dll: yes * gnome-sharp.dll: no * rsvg-sharp.dll: no * gtkhtml-sharp.dll: no * vte-sharp.dll: no NOTE: if any of the above say 'no' you may install the corresponding development packages for them, rerun autogen.sh to include them in the build. --- so we can see that gnome-sharp is not installed.(what is confirmed if I go to /opt/local/lib/pkgconfig, where there is no gnome-sharp-2.0.pc file). Do you know how I can install this dll?Is there an option of the "configure" command I didn't used? lolveley.
