mesa@17.1.6: error: Could not find llvm shared libraries

[chicagotripp (Altoine Barker)]

Mesa fails to build with the following error message:

DEBUG: Failed to locate 'lbzip2' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it?

Here are the steps of what I have to help resolve this issue: port select llvm Output:

Available versions for llvm:
	mp-llvm-3.7
	mp-llvm-3.8
	mp-llvm-3.9
	mp-llvm-4.0 (active)
	none

port info mp-llvm-4.0 Output:

Description:          The LLVM Core libraries provide a modern source- and target-independent optimizer, along with code generation support for many popular CPUs (as well as some less common ones!) These libraries are built around a well specified code representation known as the LLVM intermediate representation ("LLVM IR").

I am including the config.log and the main.log. I hope this information proves to be helpful.

The issue in your main log:

395	:info:configure configure: error: Could not find llvm shared libraries:
396	:info:configure         Please make sure you have built llvm with the --enable-shared option
397	:info:configure         and that your llvm libraries are installed in /opt/local/libexec/llvm-4.0/lib
398	:info:configure         If you have installed your llvm libraries to a different directory you
399	:info:configure         can use the --with-llvm-prefix= configure flag to specify this directory.
400	:info:configure         NOTE: Mesa is attempting to use llvm shared libraries by default.
401	:info:configure         If you do not want to build with llvm shared libraries and instead want to
402	:info:configure         use llvm static libraries then add --disable-llvm-shared-libs to your configure
403	:info:configure         invocation and rebuild.

appears to be due to the fact that the llvm libraries are built statically

$ llvm-config   --shared-mode
static

and can be fixed with

configure.args-append --disable-llvm-shared-libs

The other issues building mesa are not necessarily so easy.

This is embarrassing. I should have checked for the existence of port lbzip2 before I posted this trouble ticket. The port still fails but with a different error message. It needs to have a dependency for lbzip2. Here is my new error message after installing the port lbzip2:

configure: error: Could not find llvm shared libraries:
	Please make sure you have built llvm with the --enable-shared option
	and that your llvm libraries are installed in /opt/local/libexec/llvm-4.0/lib

	can use the --with-llvm-prefix= configure flag to specify this directory.
	NOTE: Mesa is attempting to use llvm shared libraries by default.
	If you do not want to build with llvm shared libraries and instead want to
	use llvm static libraries then add --disable-llvm-shared-libs to your configure
	invocation and rebuild.

Here are the new updated error logs that I will now include as attachments. Yes, that seems to be the only issue left. I'm going to rebuild with your suggested modification to see if that resolves this matter. I'm confident that more than likely will be the case.

I am happy to report after following your suggestion of adding:

configure.args-append --disable-llvm-shared-libs

It build and installed with no problems. I didn't check to see if lbzip2 had to be a runtime dependency or a build dependency but installing that port made the error message concerning not being able to find it go away.

The lbzip2 error message is irrelevant; please ignore it. That is a MacPorts base problem that needs to be fixed some other way.
