as the next klibc release 1.5.16 looks like shaping up, I have a trouble to build that for Debian. currently I build depent on linux-libc-dev, I don't know what against I can build latest klibc, see klibc fails to build due too: make -C linux/ ARCH=x86_64 INSTALL_HDR_PATH=debian/tmp/usr/lib/klibc/ headers_install make[3]: *** No rule to make target `headers_install'. Stop. make[2]: ***

Hi all, If any perticular OS does not have 'struct cmsghdr' in sys/socket.h and also it does not have access rights in 'struct msghdr', then how the compilation should be done ? Does anybody had similar problem earlier ? Regards, Ajit

Hi Phil, answer to your questions: > Which specific Slackware? Too embarrassed to say? Really, really don't know exactly. :) Installed approx. 5 yeras ago (maybe 4.5, 4.6, maybe 5.0 ... who knows now ... ) > Which OpenSSL? 0.9.6a? 0.9.6b? 0.9.6c? 0.9.6d? Only info I found is 0.9.6. Let's suppose it's 0.9.6. ;) > How about telling me how long you're going

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried

http://bugzilla.mindrot.org/show_bug.cgi?id=206 ------- Additional Comments From Matthew_Clarke at mindlink.bc.ca 2002-04-08 09:44 ------- More investigation shows that adding "--with-cppflags=-D_BSD=44" triggers a "struct cmsghdr" definition in the system headers, fixing the compilation error. However, that triggers changes to the WIFEXITED() macro and friends, such that they expect a "struct wait" instead of an "int", which breaks the compile of entropy.c. Read some traffic on the openssh-unix-...

Contrast http://cvsweb.mindrot.org/index.cgi/openssh/monitor_fdpass.c?r1=1.23;r2=1.24 with http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/monitor_fdpass.c.diff?r1=1.14&r2=1.15 The original replaces cmsgbuf.tmp with cmsgbuf.buf, while the -portable version *adds* cmsgbuf.buf but retains cmsgbuf.tmp. I assume this was an oversight, and cmsgbuf.tmp should be removed? DES -- Dag-Erling
