Building packages under R >= 2.7.0 (issue with gcc-4.2)
Simon, Thanks for your reply. Please see inline. Le lun. 02 juin ? 09:16, Simon Urbanek a ?crit :
Vincent, I'm sorry but somehow I have no idea what you're talking about. Your package "actuar" (in the most recent version 0.9-7 on CRAN) passes "make check" with R 2.7.0 and it is available in binary form from CRAN as well, see: http://cran.r-project.org/web/packages/actuar/index.html more comments inline: On Jun 1, 2008, at 1:50 AM, Vincent Goulet wrote:
My package checked and buit fine under 2.6.2 on Leopard 10.5.2. Under 2.7.0, 2.7.0 patched (2008-05-29) and R-devel (2008-05-30) it always fails at the "checking whether package 'actuar' can be installed" step. The 00install.log tells me that R tried to call gcc-4.2, which I don't have. It is my understanding from reading the documentation that this version of gcc is not mandatory. I have XCode v. 3.0 installed.
The compiler used in the released versions is gcc (which is by default gcc-4.0 even if you installed gcc-4.2). You can map gcc to gcc-4.2 if you desire so, but that is a non-standard setup.
I started again from scratch (deleting everything in Library/ Frameworks/R.framework and reinstalling 2.7.0) and indeed, everything is fine. It appears I had the troublesome Resources/etc/x86_64/ Makeconf file in my installation. How it got there I have no idea. Perhaps a momentary lapse of reason in the installation process at some point.
Furthermore, I noticed that, for 2.7.0, the /Library/Frameworks/ R.framework/Resources/etc/*/Makeconf files refer to gcc for i386 and ppc, and to gcc-4.2 on x86_64. For 2.7.0 patched and R-devel, the Makeconf files refer to gcc-4.2 on all architectures.
Not in the official binaries that I am releasing: /Library/Frameworks/R.framework/Resources/etc/ppc/Makeconf: CC = gcc -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk - mmacosx-version-min=10.4 -std=gnu99 /Library/Frameworks/R.framework/Resources/etc/i386/Makeconf: CC = gcc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk - mmacosx-version-min=10.4 -std=gnu99
However, as I originally stated, all Makeconf files in R-2.7-branch- leopard-universal.tar.gz and R-devel-leopard-universal.tar.gz on R.research.att.com refer to gcc-4.2. But then these are not official releases, I guess.
I can't see what I did wrong, but then I'm certainly not the first one to compile a package from source since the release of 2.7.0. Any help would be appreciated.
You'll have to tell us exactly which R build are you using. CRAN binaries are clearly not configured the way you are describing, so you must be using some custom or experimental build in which case you're on you own ... Nonetheless, even in the case of using gcc-4.2 your package installs, so I have no idea what you are concerned about.
Again, this was most likely caused by a partially oozed system. Sorry for the inconvenience and thank you again for your help and great work. Best, Vincent
Cheers, Simon
