Help with installing package lrslib-062+autotools-2017-03-03.p1

[Lisa Marie]

Hey everybody,

I have a problem with installing the package lrslib-062+autotools-2017-03-03.p1 for sage. I work on an Macbook with an Intelprocessor and MacOSX Big Sur, 11.1. I also installed every package recommended for sage. 

Can you help me fix the problem or at least say what the problem is?

The log-file of the problem is appended.

Thanks for helping!

Lisa

the problem is that the compiler in XCode 12 has unreasonable assumptions about C/C++ code.

This most probably can be fixed by setting appropriate compiler flags. See the relevant to XCode   12 and macOS 11 tickets on trac.sagemath.org

Hi,

thanks for the quick help.

I'm not really familiar with compiler flags. Could you specify your answer a bit? Would be really helpful for me!

Did you build sage from source? I had success getting lrslib to build by running:

CFLAGS=-Wno-implicit-function-declaration make lrslib

if you didn't build from source then you might try

CFLAGS=-Wno-implicit-function-declaration sage -i lrslib

thanks, that worked!
