Can't locate File/Temp.pm in @INC (you may need to install the File::Temp module)

[rayjs]

I am using a custom tool chain to compile OpenBLAS for the Target below:
Target is armv7a (32 bit) (EmbeddedOS)
Host is x86_64 Ubuntu 16

Please note that I have previously compiled successfully for armv7a for android.

I get the following error:

This looks like the installation of perl in your toolchain is somehow incomplete - the dependency on the File::Temp module was added to the c_check about two years ago, and from what I read on perldoc.perl.org this module has been a standard part of perl since version 5.6.1 (you seem to be using 5.22.1, if your perl @INC setting is correct)

[brada4]

you can install missing perl module with 'cpan File::temp'

[rayjs]

I have no control over the tool chain but thank you all for the feedback.

[martin-frbg]

You can try removing the two lines use File::Temp qw(tempfile); and
$tmpf = new File::Temp( UNLINK => 1 ); (lines 4 and 14) from c_check that got added in #941, these should only be needed on MIPS.

[brada4]

@martin-frbg
c_check uses /usr/bin/perl
Could it become /usr/bin/env perl
to accomodate environment redirections?

[martin-frbg]

@brada4 are you assuming that the wrong perl binary got called in the OP's case, or is this just a general suggestion ? (Not sure about portability)

[brada4]

Script calls /usr/bin/perl, no matter environment redirections (as seen in @@inc )
'env' is very old posix, omnipresent, NO-OP in particular case
REF https://en.wikipedia.org/wiki/List_of_Unix_commands

I dont know if we ask @rayjs to change c_check 1st line instead of
#!/usr/bin/perl
to
#!/usr/bin/env perl
Maybe it magically starts to work

[rayjs]

Thank you all for the help. I am getting a different error now. Perhaps some issue with the tool chain.

c_check file first 15 lines:

#!/usr/bin/env perl

use File::Basename;
#use File::Temp qw(tempfile);

# Checking cross compile
$hostos   = `uname -s | sed -e s/\-.*//`;    chop($hostos);
$hostarch = `uname -m | sed -e s/i.86/x86/`;chop($hostarch);
$hostarch = "x86_64" if ($hostarch eq "amd64");
$hostarch = "arm" if ($hostarch =~ /^arm.*/);
$hostarch = "arm64" if ($hostarch eq "aarch64");
$hostarch = "power" if ($hostarch =~ /^(powerpc|ppc).*/);
$hostarch = "zarch" if ($hostarch eq "s390x");

#$tmpf = new File::Temp( UNLINK => 1 );
$binary = $ENV{"BINARY"};

Commands ( I was given an incorrect 32 bit toolchain, now I am using the 64 bit tool chain)

[brada4]

You need to 'make clean' between builds.
env+perl trick was meant to get around unloadable File::Temp function (that /usr/bin/perl tries to load from redirections shown in @@inc and fails for good)

[rayjs]

Yeah I do make clean.
The commands I showed is a shell script so it ensures 'make clean' always

[brada4]

Q1: does using 'env perl' in place of 'perl' helps perl script to find File::Temp?
Q2: cause (warnings etc) should be well before error in last screen. Just a wild guess: add build parameter:
AR=aarch64-poky-linux-ar

[brada4]

@rayjs which one solved your prob ? Either sort of necessitates small polishing of makefiles.

[rayjs]

@brada4 I am not sure, I referred the toolchain provider to this page and then they compiled OpenBLAS for me.

[mxbsakura]

did you have solved the issue, I have the same issue and if you have solved it please share with,thanks a lot
