I work for buildroot. My purpose work GUI on my buildroot with Gtk3.0 and Gstreamer1.0. I use Olinuxino A13 so I wrote GUI code(Gtk3.0 hello world example) on this with codeblocks. I use Debian wheezy. I want transfer this code from Debian wheezy to buildroot.
I tried this:
I transferred /path_to_proectfile/bin/Debug/my_program.my_program created by codeblocks. I wrote ./my_program on terminal and code work. I transferred this file to my buildroot but ./my_program does not work. It returns No such file or directory error.
I thought the problem might be compiling and tried compiled on terminal. I use gcc -o my_program main.c 'pkg-config --cflags --libs gtk+-3.0' again work on Debian wheezy terminal. After I transferred to buildroot but result does not change. I tried different compile kind like cc,arm-linux-gnueabi-gcc etc. but every time No such file or directory error.
Finally when I don't use gtk library(Just use printf Hello World), I saw Hello world. When I add gtk library returns No such file or directory error. Have you any suggestion?
You need to cross compile your program with the corresponding buildroot toolchain. It looks like you have transferred a binary which was built against a different libc (this gives a "No such file or directory" error).
The buildroot cross compiler with the correct libc can be used by setting CC to "path_to_buildroot_output/host/bin/arm-linux-*-gcc" (the exact name depends on which toolchain options you have chosen).
