With Peter Dimov's help I've resolved my earlier problems packaging
Boost for Fedora.
Now my problem is that the generated .cmake files contain the full
--prefix path, which is not what I want because that's just a staging
area, not the final resting place for the files (think DESTDIR in an
autotools build).
I see lines like this in each of the installed .cmake files:
/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake:if(EXISTS
"/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake")
/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake:
get_filename_component(_BOOST_CMAKEDIR_ORIGINAL
"/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake"
REALPATH)
/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake/boost_python-1.73.0/boost_python-config.cmake:
set(_BOOST_CMAKEDIR
"/builddir/build/BUILDROOT/boost-1.73.0-0.1.fc33.x86_64/usr/lib64/openmpi/lib/cmake")
These files won't work after everything gets moved from the staging
area $RPM_BUILD_ROOT/usr/... to the final lcoation on a user's
machine, under /usr/...
I can just use sed to alter them, but surely there's way to set the
desired prefix?
I'm trying:
./bootstrap.sh --with-toolset=gcc --with-icu --prefix=/usr
./b2 -d+2 -q -j 4 \
--without-mpi --without-graph_parallel --build-dir=serial \
--prefix=/usr --libdir=/usr/lib64 \
variant=release threading=multi debug-symbols=on pch=off \
python=3.8 \
stage
...
./b2 -d+2 -q -j 4 \
--without-mpi --without-graph_parallel --build-dir=serial \
--prefix=$RPM_BUILD_ROOT/usr \
--libdir=$RPM_BUILD_ROOT/usr/lib64 \
variant=release threading=multi debug-symbols=on pch=off \
python=%{python3_version} \
install
And this produces the .cmake files with the unwanted
$RPM_BUILD_ROOT/usr prefixes.
I originally didn't have the --prefix and --libdir options on the
bootstrap.sh command and the 'b2 .. . stage' command, but it doesn't
seem to matter whether they're there or not.
Is there some way to control the prefix that ends up in those .cmake files?
