Hi. I found out that nptl make a compile error when MMU (i.e. 'Toolchain - Enable MMU support') is disabled. Detailed error message is as below. -------------------------------------------------------------------------------- In file included from libpthread/nptl/sysdeps/unix/sysv/linux/arm/fork.c:31:0: libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:61:17: error: 'fork' undeclared here (not in a function) libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:63:1: error: '__libc_fork' redeclared as different kind of symbol libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:61:23: note: previous declaration of '__libc_fork' was here libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:228:1: error: 'fork' redeclared as different kind of symbol libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:227:1: note: previous declaration of 'fork' was here libpthread/nptl/sysdeps/unix/sysv/linux/arm/../fork.c:229:1: error: '__EI_fork' aliased to undefined symbol '__GI_fork' make[1]: *** [libpthread/nptl/sysdeps/unix/sysv/linux/arm/fork.os] Error 1 -------------------------------------------------------------------------------- This problem is already reported by Axel Lin. (Link: http://lists.uclibc.org/pipermail/uclibc-cvs/2013-May/031094.html) However, it looks like that this issue is not solved for a long time. If someone let me know the alternative solution, I'd be really happy. Thank you in advances. BRs, Sangjung
