Hi,
I’m trying to compile cbang with v8 support, I need it in order to be able to compile Camotics. Any idea about how to “help” cbang to find v8?
Thank you very much in advance,
Luis Pablo
you’d need the v8-devel package installed
https://software.opensuse.org/package/v8-devel
then you’d run ./configure --with-v8 (or something similar) from the cbang src dir
you might need to tell the configure script where the v8-devel headers are
try running ./configure --help for more info
Thank you very much for your help. The v8 headers are installed:

There’s no a traditional “configure” script. Any idea?
Thank you in advance.
you seam to be missing ChakraCore.h that seams to be a part of Microsoft’s Edge
https://github.com/Microsoft/ChakraCore
according to cbang ChakraCore is a requirement see
https://github.com/CauldronDevelopmentLLC/cbang#general
and
https://github.com/CauldronDevelopmentLLC/cbang#building-chakracore
you can download ChakraCore from Microsof’t git build and install it in /usr/local then rerun the configure script
Yes! But that’s not a problem, I just need to enable v8 support. cbang can compile without ChakraCore and v8 support but I need cbang ith v8 support as a dependency of other application (Camotics) which doesn’t require cbang with ChakraCore support.
Thank you very much for your reply.
