I have a problem with static vs. dynamic linking, trying to get X support
in Emacs 18.57, using the X11 library in /usr/openwin/lib, and the SunOS
cc.
I can build a runnable xemacs if I don't define HAVE_X_WINDOWS in
config.h. No problem.
However, as I want X support in Emacs, linking temacs fails because the
OpenWindows X11 library is only available as a shared object on my IPC.
I'm using -Bstatic on the ld command which makes temacs, so
ld -L/usr/openwin/lib -e __start -Bstatic -o temacs crt0.o .... -lX11 ....
fails because the libX11.a doesn't exist.
Changing from static to dynamic linking gives the error
ld: _DYNAMIC bootstrapping not available: use -Bstatic
Having checked the Programming Utilities & Libraries manual about shared
libraries, I tried the suggested mixture of static and dynamic linking
ld -L/usr/openwin/lib -e __start -Bstatic -o temacs crt0.o .... \
-Bdynamic -lX11 -Bstatic ....
but that provokes the same error about _DYNAMIC bootstrapping.
I read that the __DYNAMIC symbol is referred to by the standard
/usr/lib/crt0.o, but using that and changing the entry point to "start"
just gives a runtime error of "ld.so: Undefined symbol: __start".
I'm sure someone must have succeeded in building Emacs with this
configuration. What's the trick?
