------=------=------=------=------=------=------=------=------=------ In Solaris 2.x static linking is not supported for any of the system libraries. All the functions that use /etc/nsswitch.conf (getXXXbyYYY, getpwXXX, etc) require the dynamic linker to load the code to load these functions. It is not possible to write configurable/extensible functions in such a way that dynamic linking is not required. E.g., you can add your own nsswitch.conf backend which would not be known to programs statically linked to only the standard backend code. ------=------=------=------=------=------=------=------=------=------ This recently drove a co-worker and I to the brink of insanity when we tried statically linking "ls" for our anonymous FTP site on a Solaris 2.4 machine. Seems like Solaris won't be able to handle this then, no? --john
It's not supported, but you CAN do it. Just make some stubs for _dlopen, _dlcose, and _dlsym that do the appropriate thing and link them in. I have a statically compiled version of ls (ported from NetBSD) that I use on our FTP server without any problems at all. Here's the code for those that are confused. Just link this in with your executable. It isn't supported, but so !@%#% what. When you need it, you need it. I just wish they'd change their position on this. #include <stdio.h> int dlclose(void *handle) {return 0;} void *dlsym(void *handle, const char *name) {return NULL;} void *dlopen(const char *pathname, int mode) {return NULL;} Link this in with your ls to make it static. Note: this doesn't fix other problems with no version of static libresolv library, but this should be easy enough to get with the bind code and linked in, and possibly be an even better resolv then the one on the system to begin with.
