Try: readelf -l /usr/bin/gcc | grep interpreter It should say "[Requesting program interpreter: /tools/lib64/ld-linux-x86- 64.so.2]". On 32-bit systems it may be /tools/lib/ld-linux.so.2. Anyway there should be a /tools prefix. If it's correct, try /tools/bin/ldd /usr/bin/python3.8 If there is any dependency "not found", that's the problem. On UNIX if "execve" call returns with ENOENT, there is no way to figure out if the executable file itself does not exist or one necessary shared object does not exist. So the shell just say "No such file" and the user should investigate to figure out the reason. (I've seen this kind of "the executable exists but shell say no such file" questions many times. Is it in the FAQ? If not we should add it.) -- Xi Ruoyao <[email protected]> School of Aerospace Science and Technology, Xidian University -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
