VBNC2017: The library 'System.Xml.dll' could not be found.

[ocgltd]

I am running on AlmaLinux9 (RedHat 9 clone) and have added mono-* from the EPEL repos. All worked well, but I also needed mono-vbnc so I downloaded the mono-basic project source from github. I ran ./configure and then make, but make is having trouble finding a dll:

I confirmed that System.Xml.dll is on my system:

$ find / -name System.Xml.dll
/usr/lib/mono/4.5/System.Xml.dll
/usr/lib/mono/gac/System.Xml/4.0.0.0__b77a5c561934e089/System.Xml.dll
/usr/lib/mono/4.7.1-api/System.Xml.dll

I have no idea how to fix this (new to mono). Do I need to specify a prefix for configure to point to /usr/lib/mono/4.5 ?

Hi!
I faced with the same problem. Here is my solution:

1. sudo apt-get install git autoconf automake libtool make gettext
2. git clone https://github.com/mono/mono-basic.git
3. cd mono-basic
4. ./configure --prefix=/usr
5. Open file "../mono-basic/build/profiles/net_4_5.make" and fix line to "PROFILE_VBNC_FLAGS = /sdkpath:$(prefix)/lib/mono/4.5/"
6. make
7. sudo make install
   The compiled files will be located at "/mono-basic/class/lib/net_4_5".
   Would be nice to add this to the manual.
