Hallo, one more with c++. Why are the macros __NFDBITS and __FDMASK redefined inside linux/posix_types.h. For me it looks the same at first glance. # make c++ -DHAVE_CONFIG_H -I. -I. -I.. -I../common -I../kcpplib -I/usr/src/linux/include -I/usr/rtlinux/include -I/usr/rtlinux/include/compat -I/usr/rtlinux/include/posix -Wall -Wstrict-prototypes -Winline -m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2 -fno-exceptions -fno-rtti -pipe -fno-strength-reduce -mpreferred-stack-boundary=2 -DCPU=686 -march=i686 -Wall -Wstrict-prototypes -D__RTL__ -D__KERNEL__ -DMODULE -D_LOOSE_KERNEL_NAMES -g -DDEBUG -c DaqCard.cc In file included from /usr/include/stdio.h:40, from /usr/lib/gcc-lib/i386-redhat-linux/2.95.2/../../../../include/g++-3/cstdio:6, from DaqCard.cc:44: /usr/include/bits/types.h:95: warning: `__NFDBITS' redefined /usr/src/linux/include/linux/posix_types.h:22: warning: this is the location of the previous definition /usr/include/bits/types.h:97: warning: `__FDMASK' redefined /usr/src/linux/include/linux/posix_types.h:34: warning: this is the location of the previous definition Next, how was in sucess to mix stl headers and kernel headers ? stl_alloc.h fails with PTHREAD_MUTEX_INITIALIZER Thanks Olaf -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
