emerge --info
oops --with-boost[=ARG] use Boost library from a standard location
(ARG=yes), from the specified location (ARG=<path>),
or disable it (ARG=no) [ARG=yes]
--with-boost-libdir=LIB_DIR
Force given directory for boost libraries. Note that
this will override library path detection, so use
this parameter only if default library detection
fails and you know exactly where your boost
libraries are located.
--with-boost-asio[=special-lib]
use the ASIO library from boost - it is possible to
specify a certain library for the linker e.g.
--with-boost-asio=boost_system-gcc41-mt-1_34
--with-boost-system[=special-lib]
use the System library from boost - it is possible
to specify a certain library for the linker e.g.
--with-boost-system=boost_system-gcc-mt
--with-boost-thread[=special-lib]
use the Thread library from boost - it is possible
to specify a certain library for the linker e.g.
--with-boost-thread=boost_thread-gcc-mt
While fixing this bug, support for boost should probably be made optional. USE=cxx is causing some confusion in the ebuild as well: USE=cxx enables asio-lib, which requires boost, but boost can be disabled independently, so that calls for a REQUIRED_USE=".. cxx? ( boost )". But building libnghttp2_asio does not imply C++ so why have USE=cxx in the first place and not USE=asio?
As I'm updating to net-libs/nghttp2-1.31.1, it turned out that myeconfargs variable in the ebuild should be extended by --with-boost=${EPREFIX}/usr. Previously I did not mention the extra "/usr" at the end.
This is a problem if cross-emerging the package, to armv6j-unknown-linux-gnueabihf in my case.
Did you encounter additional problems? passing --with-boost=${EPREFIX}/usr seems reasonable to me?
Hmm, cross emerging with that fix passes, but it doesn't install the corresponding libnghttp2_asio.so libraries. net-libs/nghttp2-1.39.1 should work fine. |
Created attachment 519604 [details] config.log I'm trying to install nghttp2, which fails to find Boost::ASIO's version. The config.log is not really descriptive: configure:20043: checking whether the Boost::ASIO library is available configure:20074: x86_64-pc-linux-gnu-g++ -c -O2 -pipe -O2 -pipe -I/home/evidgbo/usr/roots/gentoo/include conftest.cpp >&5 configure:20074: $? = 0 configure:20088: result: yes configure:20181: error: Could not find a version of the library! After debugging the configure script, I ended up that if configure gets --with-boost=${EPREFIX}, then it properly finds Boost::ASIO, as it can set BOOST_ROOT and BOOST_LDFLAGS.
