Are you sure it's latest? If you're using a snapshot there are multiple branches (iirc 1.0.DEVEL and 1.1.DEVEL or something like that) and the old one is very outdated and broken. > Unfortunately the compilation breaks with > > ----------- > ... > pcc -std=c99 -nostdinc -ffreestanding -fexcess-precision=standard -frounding-math -D_XOPEN_SOURCE=700 -I./arch/x86_64 -I./src/internal -I./include -Os -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack -Werror=implicit-function-declaration -Werror=implicit-int -Werror=pointer-sign -Werror=pointer-arith -fno-stack-protector -c -o src/aio/aio_readwrite.o src/aio/aio_readwrite.c > ../arch/x86_64/syscall_arch.h, line 37: warning: no register assignment (yet) > ../arch/x86_64/syscall_arch.h, line 46: warning: no register assignment (yet) > ../arch/x86_64/syscall_arch.h, line 47: warning: no register assignment (yet) > ../arch/x86_64/syscall_arch.h, line 56: warning: no register assignment (yet) > ../arch/x86_64/syscall_arch.h, line 57: warning: no register assignment (yet) > ../arch/x86_64/syscall_arch.h, line 58: warning: no register assignment (yet) > src/aio/aio_readwrite.c, line 23: compiler error: unsupported xasm constraint r11 > error: XXXXX/libexec/ccom terminated with status 1 > make: *** [src/aio/aio_readwrite.o] Error 1 > ----------- > > Is there any way around this, short of adding the register assignment > functionality to the compiler? Just use the #ifdef __clang__ branch of the code which handles the same brokenness in clang. :-) Rich
