Bug #: 14905
Summary: cmake+shared installation on Darwin needs
install_name_tool pass
Product: Build scripts
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: cmake
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
The cmake+shared built shared libraries and executables have been incorrectly
installed since cmake was born. Simply copying the built binaries to the
install location does not work without having to set other ld/dyld related
environment variables. The following post-install script is necessary to fix
up dependent shared library paths in binaries (fairly standard recipe for
cmake-built packages).
(libtool does this correctly at install-time)
I've been using this for a few years, but never bothered to report it before,
as it is more of a deficiency in cmake.
The script can also be trivially modified to work on DESTDIR-staged builds.
========== install-shared.sh ==========
#!/bin/sh -ev
prefix=/usr/local/wherever
make -j1 install/fast
pushd $prefix/lib
for f in *.dylib *.so
do
if test ! -L $f
then
install_name_tool -id "$prefix/lib/$f" "$f"
case $f in
*.dylib) filt="sed 1,2d" ;;
*.so) filt="sed 1d" ;;
esac
deplibs=`otool -L $f | $filt | awk '{print $1;}' | tr '\n' ' '`
for d in $deplibs
do
# prefix absolute paths to llvm/clang's lib installation
case $d in
/*) ;;
*) install_name_tool -change "$d" "$prefix/lib/$d" $f ;;
esac
done
fi
done
popd
pushd $prefix/bin
for f in *
do
if test ! -L $f
then
deplibs=`otool -L $f | sed 1d | awk '{print $1;}' | tr '\n' ' '`
for d in $deplibs
do
# consider substituting with relative @executable_path/../lib ?
case $d in
/*) ;;
@*) ;;
*) install_name_tool -change "$d" "$prefix/lib/$d" $f ;;
esac
done
fi
