Packages and -fvisibility-inles-hidden

[addeman]

Hello,

I recently started to build a new gentoo system (in a chroot) for my laptop. I use ~amd64 and i wanted to experiment a little with my CXXFLAGS. I have this in make.conf

Code: Select all

CFLAGS="-O2 -pipe -march=core2 -fomit-frame-pointer"
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden -fvisibility=hidden"

As emerge correctly warns, to flags may break packages, here is a list so far of packages that breaks:

• libusb
  libpcre
  exiv2
  cln
  htdig
  qca
  poppler
  poppler-bindings
  texlive-core ( maybe the rest of texlive-* too, i didn't bother to try)
  libqalculate
  libmodplug (xine-lib failes)
  clucene (strigi fails)

It's actually the flag -fvisibility-inlines-hidden that's causing this, since it removes the declaration and definition of functions declared 'inline'. For most this is well and good, but packages that fails uses pointers to inline functions. I don't think that is really "cosher"... Is there any other coding style that would trigger this failure? Why would someone want a pointer to an inline function?

I really wish for 'per package C(XX)FLAGS' feature

Best regards
