Compile Sage 8.9 on Opensuse Tumbleweed:Error building gfortran-7.4.0

[Shing Hing Man]

Hi,

  When I compile Sage 8.9 on Opensuse Tumbleweed, there is a problem building   gfortran-7.4.0 :

I ran

Thanks in advance for any assistance !

Do you have a 32-bit system?

Anyway, if you could install system's gfortran package it would be a way out of this.

It seems your system should have gfortran version 7,  the package is called gcc-fortran.

My CPU is AMD Ryzen 2700X, so it is 64bit.

I already have gcc-fortran-9-1.6.x86_64
  installed when I did the build earlier.

After I install gcc-fortran-32bit-9-1.6.x86_64,  and then do a make (on a new sage-8.9 folder) , the error on gfortran disappeared and  sage has built.

Thank you for your assistance !

but why do you need a 32-bit gfortran? Is something getting misconfigured?

Could you post the output of Sage's config.log if you use the "normal" gfortran?

Thanks.

Thanks. So one sees

configure:19813: result: gfortran-7.4.0 will not be installed
(configure check)

which means that Sage will not attempt to build its own gfortran.
I presume you also see

... result: gcc-... will not be installed (configure check)

Are you saying that despite this, an attempt is made to do so?
The only case this could happen is, I think, that you started a build
without gfortran installed, then
installed it, didn't

make distclean && ./configure

Hi,

   You are correct that  in my config.log,  there is message saying "gcc- ... will not be installed" :

matmsh@euler:~/installed/sages/sage-8.9> grep gcc config.log  | grep install
configure:7665: === checking whether to install the gcc SPKG ===
configure:19813: result:     gcc-7.4.0 will not be installed (configure check)
matmsh@euler:~/installed/sages/sage-8.9>

I have done a rebuilt:

> make distclean && ./configure
> make

After the rebuilt,  the config.log still contains

matmsh@euler:~/installed/sages/sage-8.9> grep gfortran config.log  | grep install

configure:13595: === checking whether to install the gfortran SPKG ===

configure:19813: result:     gfortran-7.4.0 will not be installed (configure check)

matmsh@euler:~/installed/sages/sage-8.9> grep gcc config.log  | grep install
configure:7665: === checking whether to install the gcc SPKG ===
configure:19813: result:     gcc-7.4.0 will not be installed (configure check)

Below are intalled Fortran related rpm packages.

matmsh@euler:~/installed/sages/sage-8.9> rpm -qa | grep fortran
libgfortran4-7.5.0+r278197-1.1.x86_64
gcc9-fortran-32bit-9.2.1+r275327-1.3.x86_64
libgfortran5-9.2.1+r275327-1.3.x86_64
gcc-fortran-32bit-9-1.6.x86_64
libgfortran5-32bit-9.2.1+r275327-1.3.x86_64
gcc9-fortran-9.2.1+r275327-1.3.x86_64
gcc-fortran-9-1.6.x86_64
matmsh@euler:~/installed/sages/sage-8.9>

As Sage is working on my PC, I will leave it as it.

Thanks for your comments !
