How to install on RHEL with Static lib V8 pre-downloaded (no live internet connection nor admin rights) ?

[jmbo1190]

Hello, would it be possible to specify the location of the static libV8 e.g. in an environment variable (previously downloaded from a separate machine and copied to the RHEL system) instead of downloading during the installation process ?

This would help when you have no direct internet access nor sudo rights!

Yes you can set envvars V8_PKG_LIBS and V8_PKG_CFLAGS

V8/configure

Lines 15 to 19 in dff09bc

	if [ "$V8_PKG_LIBS" ]; then
	PKG_LIBS="$V8_PKG_LIBS"
	PKG_CFLAGS="$V8_PKG_CFLAGS"
	DISABLE_STATIC_LIBV8=1
	fi
