Hello, When compiling syslog-ng 3.2.1 into my environment I discovered a bug in how this configure option is applied: --libexecdir=/home/y/libexec64 When this option is entered, this is generated in lib/syslog-ng.h: #if ENABLE_ENV_WRAPPER #define PATH_SYSLOGNG PATH_PREFIX "/libexec/syslog-ng" #endif As you can see this is a hard coded libexec path which does not match what my environment expects. Unfortunately it appears that the libexec variable never makes it into a C macro so I'm not totally clear on how to make a permanent patch for this one. I will work around it with something like this temporary patch for now. --- /home/megahall/syslog-ng.h 2010-12-13 15:54:56.000000000 -0800 +++ syslog-ng-3.2.1/lib/syslog-ng.h 2010-12-13 16:06:22.000000000 -0800 @@ -44,7 +44,7 @@ #define PATH_PIDFILE PATH_PIDFILEDIR "/syslog-ng.pid" #define PATH_CONTROL_SOCKET PATH_PIDFILEDIR "/syslog-ng.ctl" #if ENABLE_ENV_WRAPPER -#define PATH_SYSLOGNG PATH_PREFIX "/libexec/syslog-ng" +#define PATH_SYSLOGNG PATH_PREFIX "/libexec64/syslog-ng" #endif #define PATH_PERSIST_CONFIG PATH_LOCALSTATEDIR "/syslog-ng.persist" Another issue. Because of this bug syslog-ng fails to launch with return code 127. But it prints nothing to the console explaining why it failed: execve("/home/y/libexec/syslog-ng", ["/home/y/sbin64/syslog-ng"], [/* 21 vars */]) = -1 ENOENT (No such file or directory) exit_group(127) = ? I think some message should be added in syslog-ng/wrapper.c. This is an uncompiled example but should be very close. --- /home/megahall/wrapper.c 2010-12-13 16:15:29.000000000 -0800 +++ syslog-ng-3.2.1/syslog-ng/wrapper.c 2010-12-13 16:14:21.000000000 -0800 @@ -45,6 +45,7 @@ putenv(ldlibpath); } #endif + fprintf(stderr, "syslog-ng failed to launch because of XYZ\n"); execv(PATH_SYSLOGNG, argv); return 127; } Thanks for maintaining syslog-ng. I hope this helps keep the product great! Regards, Matthew Hall.
