I tried this, but this broke because SQLite3's build system builds executable build tools. So I could (and tried) making those targets separately, but then I realized that I was encoding too much knowledge of the internals of SQLite3's build system into the SFW makefile and decided that was not good. Or perhaps I could add -z ignore to LD_OPTIONS too (to ignore the symbols listed in the mapfile when building those interim executables). And use a separate target for the one executable that is installed (so it gets the noexecstack mapfile). > >BTW, I rather expect that we'll see a lot more of this as we add more > >and more libtool-using FOSS to SFW. > > Yes. We've both excited and afraid of this :-) Heh. OK, so for now I'll simply punt on symbol reduction. Nico --
