I pulled all the source files, and then ran the following command to configure and tried to build vim with GUI support:
/configure --enable-gui=auto
Here is some more information:
checking --enable-gui argument... yes/auto - automatic GUI support
checking whether or not to look for GTK+ 2... yes
checking --disable-gtktest argument... gtk test enabled
checking for location of Motif GUI includes... <not found>
But the vim I compiled still doesn't support GUI.
vim --version
VIM - Vi IMproved 8.1 (2018 May 18, compiled Jul 6 2018 16:24:24)
Included patches: 1-155
Compiled by coeus@debian9
Huge version without GUI. Features included (+) or not (-):
I am using Debian Stretch. Can anyone help me?
I tried to follow up with INSTALL file, but it seems it doesn't work, and there are no error messages mentioning the GUI is not compiled... Very strange.
