Hi Mike, I am building uClinux-dist-2008R1-RC8 from source, and I am getting messages like
strace.o: In function `strace_popen': ../strace-4.5.15/strace.c:274: undefined reference to `_fork' I think this is because my uclibc does not provide fork() for blackfin. Which is totally expected. On the other hand, uClinux-dist-2008R1-RC8 was successfully built by others, without doubt. Which is a contradiction. I downloaded blackfin-toolchain-uclibc-default-08r1-8.i386.tar.gz and indeed, I see in opt/uClinux/bfin-uclinux/bfin-uclinux/runtime/usr/include/unistd.h: #if 1 || defined __ARCH_USE_MMU__ /* Clone the calling process, creating an exact copy. Return -1 for errors, 0 to the new process, and the process ID of the new process to the old process. */ extern __pid_t fork (void) __THROW; #endif It also has libc.a::fork.o which seems to be a stub. Current svn in the same spot in include/unistd.h says: #ifdef __ARCH_USE_MMU__ /* Clone the calling process, creating an exact copy. Return -1 for errors, 0 to the new process, and the process ID of the new process to the old process. */ extern __pid_t fork (void) __THROW; #endif Am I reading this correctly to mean that current uclibc svn can't be used unmodified to build uClinux-dist-2008R1-RC8 on blackfin? -- vda _______________________________________________ uClibc mailing list [email protected] http://busybox.net/cgi-bin/mailman/listinfo/uclibc
