make && make install

mono is at current master

./autogen.sh --prefix=/mono --enable-llvm
make && make install
  CC       libmini_la-mini-llvm.lo
mini-llvm.c:40:2: error: #error "The version of the mono llvm repository is too old."
 #error "The version of the mono llvm repository is too old."
Makefile:2350: recipe for target 'libmini_la-mini-llvm.lo' failed

this error hit always i use --enable-llvm

Use the 'master' branch of the llvm repo, the 'mono' branch is obsolete.
Comment 2 pr0vieh 2015-03-26 06:42:01 UTC
With clone https://github.com/mono/llvm.git the same
With git checkout master the same

I have test this with a clean llvm master and the same issue i see you have set in last commit MONO_API_VERSION 4 this is exist in config/llvm-config but in your change @mono you check LLVM_API_VERSION is this right ?
Comment 3 Zoltan Varga 2015-03-26 06:51:03 UTC
Yes, it is right,  MONO_API_VERSION is taken from <llvm prefix>/include/llvm/Config/llvm-config.h and defined as an LLVM_API_VERSION define when compiling mono.
Comment 4 Zoltan Varga 2015-03-27 12:03:51 UTC
--enable-llvm picks up which llvm to use from PATH, try using --with-llvm=<prefix> instead.
Comment 5 pr0vieh 2015-03-27 13:02:48 UTC
Ok this works for me thx for help

i think update the documentation is a good way to prevent new requests about this
