This is fine.

On a GCC/ELF platform it may be simply $(CC) -shared on others it can invoke the linker with special options or what not. > see for example the *bsd and sunos4 entries in Makefile.shlib. Note that in sunos $(LD) -assert pure-text -Bdynamic the -Bdynamic option is not the same as the -Bsymbolic option. -Bdynamic simply means "create a shared library". (Not sure about the -assert thing, I think it ensures that the library is somewhat self contained.) Also, the *bsd lines you might be referring to $(LD) -x -Bshareable -Bforcearchive the -Bshareable is the flag to make a shared library, -Bforcearchive is completely unnecessary, and -x says "Discard all local symbols in the input files.", whatever that may mean. (In fact, I'm fairly convinced that this is not the recommended way to link shared libraries on these systems, but I don't have enough enthusiasm to amend this.) > These examples are why I added -Bsymbolic to HPUX's LINK.shared in the > first place, and I'm now inclined to leave it that way. Comments? Well, this is not really related. Makefile.shlib and LINK.shared say "link a shared library in some default way". The shlib_symbolic macro says "link a shared library in some other way". Now you can postulate the "other way" to be the new "default way", but at least that's how the setup is. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/
