Is there any way to tell which version of gcc an executable is compiled with?
Hello :)
Maybe can be a better way :) But this just works.
strings -a /the/file | grep -m1 GCC
Good Luck!
Seems to work, but only on binaries and libraries that have been compiled against glibc. Libraries compiled against uclibc won't show this information.
Rare, this is not related to what "libc" used, is just an assembler label (.ident) that GCC put in the output .s file. What are the commands that you use to build the library? Compiling an executable/library with toolchain-ulibc works fine here. $ x86_64-unknown-linux-uclibc-gcc -fPIC -c hola.c $ x86_64-unknown-linux-uclibc-gcc -shared -o hola.so hola.o $ strings -a hola.so | grep -m1 GCC: GCC: (GNU) 4.4.0 20090526 (prerelease) $ readelf -d hola.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [libgcc_s.so.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.0] -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D
