 Solaris <= 7 doesn't have any ldconfig equivalent. Solaris 8 has crle.
 
 Creating shared libs is pretty much system dependent. With gcc on Solaris,
 you compile everything with -fPIC, and the correct Solaris linker invocation
 (you have /usr/ccs/bin in your PATH, have you?) would be something like

 ld -G [-L... -R...] -h libfoo.so.$MAJ -o libfoo.so.$VERS $OBJS

 You can leave out the -h part.

 Now, to link against shared libs: do *NOT* use LD_LIBRARY_PATH.
 It is generally frowned upon for security reasons.

 Use either "LDFLAGS = -R/path/to/foolibdir -lfoo" or

 $ LD_RUN_PATH=/path/to/foolibdir make

 Only the latter worked for me with php4, because libtool fscked up the
 LDFLAGS part.

 There :)
