here is my proposed patch to allow, at configure, time the production of
shared library with versioned symbols. i used it to build curl 7.14.1-1
debian package now in experimental.
Thanks!
I like the general spirit, but I have a few remarks:
1 - it checks the --help output from 'ld' to decide if version-script works
or not. Please make a runtime test instead, as all versions may not
mention the option, or perhaps a version mentions it but doesn't work
properly
2 - when versioned symbols are enabled, you assume you can send linker options
to the linker with -Wl, but you didn't check if gcc (or a gcc option
compliant compiler such as icc) is in use. AFAICS, if I have the GNU ld
installed but use a different compiler, this might break.
3 - only symbols starting with curl_ are globally available. Curl_ and curlx_
are not.
