I unable to Ta-lib, a module for technical analysis in python3 in an always free ARM 64(AArch64) Amepere processor with Ubuntu 20 from Oracle cloud. To verify if the steps I followed are correct, I manage to install successfully in a X64 VM with AMD processor. Thus, I tink AArch64 may need some tweak to install Ta-lib.
The steps I used are below (https://sachsenhofer.io/install-ta-lib-ubuntu-server/)
wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
tar -xzf ta-lib-0.4.0-src.tar.gz
cd ta-lib/
./configure
make
sudo make install
The error I found in my Ubuntu terminal for ./configure as below

It turns out having an installed x86_64 version of TA-Lib will interfere with the installation of the arm64 version of TA-Lib.
please uninstall the x86_64 version of TA-Lib using brew uninstall ta-lib first before installing the arm64 version of TA-Lib.
Some possible debugging:

/opt/homebrew/bin/brew
➜ brew --prefix ta-lib

Just download the newsest config.guess config.sub from the source and repeat the configure & make install progress. ta-lib will install successfully.
ta-lib-config --version

I installed another version of gcc (9.2.0) to a non-default folder in my Linux machine and pointed $PATH to that new location. gcc and g++ are working but there is no cc so I made a symlink:
ln -s $HOME/.local/bin/gcc $HOME/.local/bin/cc
I thought cc now points to the correct one
$ ~/.local/bin/cc --version
cc (GCC) 9.2.0
$ which cc
~/.local/bin/cc
but without the full path, cc still uses the old version
$ cc --version
cc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-16)
I could not understand how this could happen. Any help is appreciated.
I am learning x86_64 assembly. But I have run into the following problem:
I am assembling a program with gcc -g -c exercise1.s -o exercise1.o and linking it with ld -g -o exercise1 exercise1.o -m elf_x86_64
However when I try to run the program I get the following error: bash: ./exercise1: cannot execute binary file: Exec format error
Running uname -a I get Linux lubuntu 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux and arch outputs x86_64.
file outputs exercise1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), corrupted program header size, with debug_info, not stripped.
To me it seems that I am trying to run a 64-bit program on a 64-bit kernel on a 64-bit CPU. Why is it not working?
I am new to Linux and unfamiliar with gfortran.
I am trying to install gfortran lapack (according to instructions here) to install JAGS for R on a Linux Mint 17.2 64 bit machine. My system settings are:
[14:20] ~/lapack-3.6.1$ uname -a
Linux X1Carbon 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
On running make in the lapack directory, this is the error received:
[14:10] ~/lapack-3.6.1$ make
( cd INSTALL; make; ./testlsame; ./testslamch; ./testdlamch; \
./testsecond; ./testdsecnd; ./testieee; ./testversion )
make[1]: Entering directory `/home/joanna/lapack-3.6.1/INSTALL'
gfortran -O2 -mtune=pentium4 -c lsame.f -o lsame.o
f951: error: CPU you selected does not support x86-64 instruction set
make[1]: *** [lsame.o] Error 1
make[1]: Leaving directory `/home/joanna/lapack-3.6.1/INSTALL'

/bin/sh: 2: ./testieee: not found
/bin/sh: 2: ./testversion: not found
make: *** [lapack_install] Error 127
Other sites such as here reference a similar error but it is to do with a -march=i686 flag which is not present in the gfortran command line that is run.
Could anyone suggest what the problem is and how to fix it? Many thanks in advance.
My Linux Server information is:
[root#centos nan]# uname -a
Linux centos 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
By default, the gcc will generate the 64-bit executable file, so I use the "-m32" flags to build 32-bit executable file.
After running the following command:
[root#centos nan]# gcc -m32 -o a a.c
/usr/bin/ld: crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status
So how to build 32-bit executable file in 64-bit Linux?
