llmv-g++4.2 for mac os 10.8.5 to compile Rosetta3.5

[Anonymous]

Hello all,
I try to build reosetta on a mac os 10.8.5 to use Erraser within Phenix 1.8.4-1496.
When I type
benoit1$ python external/scons-local/scons.py -j2 bin mode=release
Verbose gives
scons: Reading SConscript files …

Apparently llmv-g++-4.2 is not installed on my machine. Anyone know how to do that since I didn’t manage even after updating the Xcode5.0.2 command line.
Thanks in advance…

What compiler do you want to use? (Which ones do you have installed? IIRC, you need to explicitly install the developer tools on Macs to get a compiler – the default installation doesn’t have a compiler installed.)

There’s a number of options that the Rosetta scons setup takes which can control which compiler is used for builds. In the absence of the flags, it tries to do autodiscovery, which *usually* works. Run with the -h option to see the full description of what options are available, but the ones you’re most interested in are likely cxx and cxx_version. Adding something like “cxx=clang” or “cxx=clang cxx_ver=3.3” to the commandline might help. (Change compiler and version as appropriate for your system.)

By the way, if the compiler you do want to run is actually llvm-g++-4.2 and it’s installed, a likely cause of the error message is some issue with your path. You need to be at a point where doing a “which llvm-g++-4.2” gives you the path to your compiler. You may just need to add a symlink in a bin directory, or add something to your path in your shell setup file.

Thanks again. I input the command line as you suggested and it output the following. Still this llmv-g++4.2 appearing in the verbose. Any advice?
Cheers.

Thanks for your answer.

I don’t know how to edit scons.py to specifically use a given compiler. Scons.py seems to call llvm-g++-4.2 since the verbose mentions the command is not found. But I don’t have it installed and don’t manage to do it. I have gcc and g++ in /usr/bin. Xcode has installed gcc and g++ (which gcc answer positively /usr/bin/gcc). There are 2 ways to solve the pb according to your answer, either changing the compiler in scons.py, or to install llvm-g++-4.2 which I don’t manage to find or install.

You don’t need to actually edit the scons.py script, you just need to add parameters to your commandline. As you want a regular gcc compiler, all you have to do is change the command from this:

python external/scons-local/scons.py -j2 bin mode=release

To this:

python external/scons-local/scons.py -j2 bin mode=release cxx=gcc

Okay, I was off on telling you to use “cxx=gcc”, as the issue is that Rosetta apparently thinks that the “gcc” compiler for MacOS 10.8 is called “llvm-g++-4.2”.

The surefire way to fix it is to go into rosetta_source/tools/build/basic.settings, find the “gcc, 4.2, macos, 10.8” and “gcc, 4.2, macos, 10.7” blocks at around line 440, and change the “llvm-gcc-4.2” and “llvm-g++-4.2” to “gcc” and “g++” respectively.

Hello,
Your suggestion helped a lot. At least I got compilation to proceed. However compilation stopped at some point due to an error. Follows the verbose.

Thanks in advance for your help.

Which version of g++ are intending running, exactly? (What does “g++ –version” report?)

I tracked down some old versions of gcc, and the earliest version I could get to compile was 4.6. Earlier version, including 4.1 and 4.2, errored out with template issues (though not the issue you’re seeing) – though some of that might be other random settings on the machine I was trying it on.

The other thing you may be able to try is following the compiler error message, and add the ftemplate-depth flag to the compiler flags. Go to main/source/tools/build/basic.settings and around line 125 or so, in the main “gcc” block, find the line that sets the compile flags (something like `”compile” : [ “pipe”, “ffor-scope” ],`) and change it to something like `”compile” : [ “pipe”, “ffor-scope”, “ftemplate-depth=1024” ],`

To clarify, Rosetta still supports compilation with gcc 4.1. It looks like the issues I was having with earlier gcc versions has to do with the way they were installed on my system. The main Rosetta testing server is using gcc 4.1 and 4.2 and is not having issues with compilation.

Hello,

The fttemplate-depth modification was the trick!

Below follow the last lines of the verbose before getting back the prompt control. No error has been reported and all files have been installed a priori.

Install file: “build/src/release/macos/10.8/64/x86/gcc/4.2/default/zinc_heterodimer_design.default.macosgccrelease” as “bin/zinc_heterodimer_design.default.macosgccrelease”
scons: done building targets.

Now I can check if it works within Phenix.

Many thanks.
