The use of dlopen() does not circumvent that you're creating a modified version. The GPL-incompatible code and the GPL code do not communicate at arms length. Hence, the GPL-incompatible code is to be relicensed if the modified work is to be distributed.i Alternatively, ask the license holder for an exception or see if the library can be relicensed under the LGPL. >From a GPL licensing point of view dlopen() is no different than static linking. > > > I'll also point out that the ELF specification does not define static > > > linking *at all*. > > > > I think that's because it doesn't need any special mention. > > Well, it specifically mentions being able to do something like > linking libc to libresolv, so that you implicitly get the resolver > library when you explicitly link in the C library.

Recording dependencies in ELF files is specific to dynamic linking. In fact, there's nothing that you need to add to ELF headers or sections to make static linking work. It's irrelevant to an ELF specification. That's why it's not mentioned. Dynamic linking needs special headers and/or sections in the ELF file to make it work. I don't think you can infer from the ELF specification that static linking is undefined. -- Marcel Moolenaar USPA: A-39004 [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
