New submission from Trevor Bowen: FWIW, I'm using a Freescale cross-compile tool-chain on a Linux x86-64 build host, although I have duplicated the cross-compile error on an x86 Ubunutu 10.04 build host.
Steps to reproduce: $ wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2 $ tar -jxf Python-2.7.5.tar.bz2 $ cd Python-2.7.5 $ export PATH="/opt/freescale/usr/local/gcc-4.3.74-eglibc-2.8.74-dp-2/powerpc-none-linux-gnuspe/bin:${PATH}" # For info only: $ ls -l /opt/freescale/usr/local/gcc-4.3.74-eglibc-2.8.74-dp-2/powerpc-none-linux-gnuspe/bin total 10472 -rwxrwxrwx 1 root root 590485 Mar 5 2012 powerpc-none-linux-gnuspe-addr2line -rwxrwxrwx 1 root root 614647 Mar 5 2012 powerpc-none-linux-gnuspe-ar -rwxrwxrwx 1 root root 897161 Mar 5 2012 powerpc-none-linux-gnuspe-as -rwxrwxrwx 1 root root 235382 Mar 5 2012 powerpc-none-linux-gnuspe-c++ -rwxrwxrwx 1 root root 589227 Mar 5 2012 powerpc-none-linux-gnuspe-c++filt -rwxrwxrwx 1 root root 234277 Mar 5 2012 powerpc-none-linux-gnuspe-cpp -rwxrwxrwx 1 root root 8503 Mar 5 2012 powerpc-none-linux-gnuspe-embedspu -rwxrwxrwx 1 root root 235382 Mar 5 2012 powerpc-none-linux-gnuspe-g++ -rwxrwxrwx 1 root root 233126 Mar 5 2012 powerpc-none-linux-gnuspe-gcc -rwxrwxrwx 1 root root 233126 Mar 5 2012 powerpc-none-linux-gnuspe-gcc-4.3.2 -rwxrwxrwx 1 root root 16512 Mar 5 2012 powerpc-none-linux-gnuspe-gccbug -rwxrwxrwx 1 root root 28017 Mar 5 2012 powerpc-none-linux-gnuspe-gcov -rwxrwxrwx 1 root root 655127 Mar 5 2012 powerpc-none-linux-gnuspe-gprof -rwxrwxrwx 1 root root 1036372 Mar 5 2012 powerpc-none-linux-gnuspe-ld -rwxrwxrwx 1 root root 603678 Mar 5 2012 powerpc-none-linux-gnuspe-nm -rwxrwxrwx 1 root root 750617 Mar 5 2012 powerpc-none-linux-gnuspe-objcopy -rwxrwxrwx 1 root root 895336 Mar 5 2012 powerpc-none-linux-gnuspe-objdump -rwxrwxrwx 1 root root 614647 Mar 5 2012 powerpc-none-linux-gnuspe-ranlib -rwxrwxrwx 1 root root 264063 Mar 5 2012 powerpc-none-linux-gnuspe-readelf -rwxrwxrwx 1 root root 593901 Mar 5 2012 powerpc-none-linux-gnuspe-size -rwxrwxrwx 1 root root 591853 Mar 5 2012 powerpc-none-linux-gnuspe-strings -rwxrwxrwx 1 root root 750617 Mar 5 2012 powerpc-none-linux-gnuspe-strip $ ./configure --host=powerpc-none-linux-gnuspe \ --build=i586-linux-gnu --prefix=/ \ --disable-ipv6 ac_cv_file__dev_ptmx=no \ ac_cv_file__dev_ptc=no $ make Make fails because the foreign (powerpc, in this case) pgen binary is used to build the $(GRAMMAR_H). Instead, a native version of the python interpreter (preferrable) and pgen (essential) need to be built first using the host's toolchain. Then, these tools can be used to build the full foreign suite. FWIW, This 2 step process is well documented here: http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html However, the cross-compile fixes from Issue17086 may have helped this process. (It's hard for me to determine how to take advantage of these updates.) Certainly, they changed the above process dramatically. Incidentally, Python 3.3.2 exhibits almost the exact same build error, if not the same. Build log on an x86-64 host for Python-2.7.5 for a PowerPC-linux target is attached.
