I search this , I found I must install gcc but gcc remove apt list(i installed clang but still cannot operate)

How can I fix it?

the __mulodi4 means you haven't linked against compiler_rt
i think you need to specifically add -lm and -lcompiler_rt flags to compiler and it will work

[makerdark98]

I try

LDFLAGS=" -lm -lcompiler_rt" pip install numpy

But I didn't work.
How can I add -lm -lcompiler_rt flags to compiler while installing numpy?

LDFLAGS=" -lm -lcompiler_rt" pip install numpy

Ooooooh~
I fixed it
LDFLAGS="-lm -lcompiler_rt" pip install --no-cache-dir numpy
I think I was stupid.
Thanks your answer add LDFLAGS
I am really really happy . Yeah!

[chewenkai]

Thanks for the solution. I meet the same situation.

[4thirteen2one]

Thanks a lot for solving my problem too!

[its-pointless]

For the sake of completeness I have scipy working as well in a repo of mine.

[Eliran79]

Can anyone explain me the purpose of:LDFLAGS="-lm -lcompiler_rt" ?

My termux is *8 times faster them my (i3 4G ram) laptop and I suspect it has something to do with it...
