Error compiling sage from source in arch linux: error installing package gcc-5.4.0, openblas

[David Lowry-Duda]

I am currently trying to build sage from source on an arch linux machine. I have only recently set up this arch linux machine, and I should preface this by saying that I still have a few things to learn about arch itself. However, I have built sage from source in Ubuntu and on Mac OSX before, so I am at least familiar with the process.

The problem occurs early in the build. I cloned the git repo, changed to the develop branch, and enter `make`.

I have attached the openblas and config logs. The gcc log is very large, but the tail is the following (please let me know if you want more from it):

My gcc version is 7.1.1.

I note that I also have g++ (version 7.1.1) and gfortran (version 7.1.1). I have attempted to set the environmental variable SAGE_INSTALL_GCC in the past so that sage does not attempt to build a new gcc, but not on this particular build. I will momentarily be setting `export SAGE_INSTALL_GCC=no` and trying to build again (as I've been twiddling a few things here and there). Somehow, this hasn't seemed to convince sage to not make a gcc. From documentation, I believe that one should be able to understand why sage things building its own gcc is necessary from the config.log file, which is why I've included it.

I'm sorry if this has been answered elsewhere. I looked up other topics that seemed somewhat similar, but I didn't find anything that worked for me. I understand that arch linux is not particularly well supported. Perhaps if this works out, then I will be able to spend more time thinking about sage on arch.

Thank you-

[David Lowry-Duda]

I have now managed to build sage on arch linux. Allow me to describe the final process notes.

Firstly, I manually set environmental flags for the C, C++, and Fortran compilers. For instance, I used

export GCC=/usr/bin/gcc

I did the same for CC, CXX, CPP. I set SAGE_INSTALL_GCC=no. This was sufficient, it seems, in preventing sage from trying to compile its own gcc. I was a bit surprised that merely setting SAGE_INSTALL_GCC=no wasn't enough.

I also encountered the same openblas error that a few others have reported here. This was solved in by setting OPENBLAS_CONFIGURE to "TARGET=ATOM", as noted in https://groups.google.com/forum/#!topic/sage-support/Tv68G0h8Keg (and elsewhere). I note that Atom worked, even though I did not actually check to see what sort of architecture lies underneath.

Do you have another (g)cc in your path?

Do you have gfortran installed? (if not, building gcc would be triggered, as gfortran is built along with it)

(It could also be that gfortran is installed, but fails a test: the same net effect).

I don't think GCC variable is used; but CC, etc are used.

Firstly, you're right about GCC not being used. I set environmental variables for CC, CXX, CPP, and FC. (I then typed what seemed obvious to me in the google group, and chose one that doesn't make sense. Whoops!). I do have gcc, g++, and gfortran installed.

I wonder if this is a case where arch has some blazing new gcc, g++, or gfortran that happens to fail some test.

In my path, I do have a /usr/bin/cc as well. I also have x86_64-pc-linux-gnu-gcc, x86_64-pc-linux-gnu-gcc-7.1.1, if that's helpful.

I'm marking this as complete, but of course I am happy to continue this line of inquiry.
