w_scan cross compile issue

问题:

I download the w_scan project(a small command line utility used to perform frequency scans for DVB and ATSC transmissions.) from http://wirbel.htpc-forum.de/w_scan/index_en.html. I also install gcc-arm-linux-gnueabi on my Ubuntu x86_64.

I use the ./configure --host=arm-linux CC=arm-linux-gnueabi-gcc command to cross-compile, and it generates a binary file. However, I copy that file to my target board and execute that file, it shows sh: ./w_scan: No such file or directory.

I use the file command to see information of that binary file, it shows ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.31, BuildID[sha1]=0x9a584b4720fadf5eb5b77034ac85092daeb728c9, not stripped.

I found that error message stands the configuration of cross-compile doesn't correct.(reference http://ubuntuforums.org/showthread.php?t=1141792). How can I fix my configuration and correct cross-compile that project, THANKS!

回答1:

1. ./configure --host=arm-linux CC=arm-linux-gnueabi-gcc
2. make CFLAGS=-static
3. copy that binary file to my target board, it can execute normally and successfully.

And the file w_scan will shows ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.31, BuildID[sha1]=0x67b7e9f93015607f891c0b77493d9e47059ef6a1, not stripped.
