Compilation error: unknown type name ‘VTermSelectionMask’

[bbatsov]

I've installed all the required things for the build, but I get the following error:

Any pointers on how to resolve this will be appreciated!

You should upgrade your libvterm to 0.2

[bbatsov]

Someone should update the instructions here, then:

OPTIONAL: libvterm (>= 0.1). This library can be found in the official repositories of most distributions (e.g., Arch, Debian, Fedora, Gentoo, openSUSE, Ubuntu). Typical names are libvterm (Arch, Fedora, Gentoo, openSUSE), or libvterm-dev (Debian, Ubuntu). If not available, libvterm will be downloaded during the compilation process. Some distributions (e.g. Ubuntu < 20.04, Debian < 11) have versions of libvterm that are too old. If you find compilation errors related to VTERM_COLOR, you should not use your system libvterm. See FAQ for more details.

I've got Ubuntu 20.04 with libvterm-0.1.2, which should be fine according to the README.

I have this problem too on Ubuntu 18.04. It works when I set vterm to ignore system libvterm for compiling.

(setq vterm-module-cmake-args "-DUSE_SYSTEM_LIBVTERM=Off") ; note that -DUSE_SYSTEM_LIBVTERM=no will not work

this should have be fixed .
