Dear Sir,

I want to port perl to embedded Linux . my environment is : ARM-Linux
,use xscale_be-gcc C compile .

I according to the steps in "Cross-compilation" section in INSTALL in
~/perl-5.8.8

Like this :

  sh ./Configure -des -Dusecrosscompile \

  -Dtargethost=*.*.*.*\

  -Dtargetdir=/tar/get/dir \

  -Dtargetuser=wuliu \

  -Dtargetarch=arm-linux \

  -Dcc=xscale_be-gcc \

  -Dusrinc=/opt/Perl_install/usr/local/include\

  -Dincpth=/opt/Perl_install/usr/local/include \

  -Dlibpth=/opt/Perl_install/usr/local/lib \

  -D...

Our host that running redhat 's ip address is *.*.*.*

But this is can't run success

The error :

I've tried to compile and run the following simple program​:

#include <stdio.h>

int main() { printf("Ok\n"); return(0); }

I used the command​:

  xscale_be-gcc -o try -O2 -DOVR_DBL_DIG=14 try.c

  /home/roger/Perl/perl-5.8.8/Cross/run-ssh ./try

and I got the following output​:

Permission denied, please try again.

bash​: line 1​: ././try​: cannot execute binary file

The program compiled OK, but exited with status 126.

You have a problem. Shall I abort Configure [y]

Ok. Stopping Configure.

I don't know what is wrong ,

Our target machine that my program run on it and host machine that my
program compile and build on it should be connect use SSH?

Thank you

Wu Liu

Do we have anyone familiar with cross-compilation issues who could take
a look at this ticket?

Thank you very much.

Re-posing the question 15 months later​: Is there someone familiar with

It's been quite a long time, but if you're still interested in
cross-compiling perl, the first recommendation would be to use castaway's
branch​:
https://github.com/castaway/perl/tree/jrobinson/configure-for-cross
Since that simplifies the process considerably.

Like this :

sh \./Configure \-des \-Dusecrosscompile \\

    \-Dtargethost=\*\.\*\.\*\.\*\\

    \-Dtargetdir=/tar/get/dir \\

    \-Dtargetuser=wuliu \\

    \-Dtargetarch=arm\-linux \\

    \-Dcc=xscale\_be\-gcc \\

    \-Dusrinc=/opt/Perl\_install/usr/local/include\\

    \-Dincpth=/opt/Perl\_install/usr/local/include \\

    \-Dlibpth=/opt/Perl\_install/usr/local/lib \\

    \-D\.\.\.

Our host that running redhat 's ip address is *.*.*.*

Hm, unless I'm reading this wrong, it sounds like you used that IP address
in -Dtargethost, rather than setting it to the target's IP? This sounds
like a "did you turn it off and on again" sort of question, but it's worth
checking.

But this is can't run success

The error :

I've tried to compile and run the following simple program​:

#include <stdio.h>

int main() { printf("Ok\n"); return(0); }

I used the command​:

    xscale\_be\-gcc \-o try \-O2 \-DOVR\_DBL\_DIG=14 try\.c

and I got the following output​:

bash​: line 1​: ././try​: cannot execute binary file

The program compiled OK, but exited with status 126.

It's possible that the user you're connecting to the device with doesn't
have the necessary permissions for the targetdir you specified? Even if you
do have the permissions, can you try creating a simple shell script, giving
it an execute bit, and trying to run it manually? Some OSs have partitions
mounted with the no-exec bit set (hello, Android's /sdcard), which trumps
everything else.
