--- Begin Message ---Package: icu Version: 3.6-1 Severity: wishlist Tags: patch The ICU shared libraries are all linked against libpthread, but the only pthread functions ICU actually uses are: libicuuc.so: U pthread_mutex_destroy libicuuc.so: U pthread_mutex_init libicuuc.so: U pthread_mutex_lock libicuuc.so: U pthread_mutex_unlock On a glibc-based system, these functions are all in libc, so the ICU libraries can safely be built without linking against libpthread. It is desirable to avoid libpthread, because glibc attempts to ensure that single-threaded programs are not subject to the overhead of thread safety, and it detects multi-threadedness by checking whether libpthread is loaded at runtime. Thus, any single-threaded program that uses ICU is currently subject to unnecessary overhead. It's possible to avoid linking ICU against libpthread by a clever trick which does not involve any modifications to the upstream source, and this is what I have done in the appended patch. It applies relative to the top level of the directory you get by unpacking the source deb (*not* to build-tree/). -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.17-2-686 Locale: LANG=en_US, LC_CTYPE=en_US (charmap=UTF-8) -- patch: --- debian/rules 2006-09-24 11:48:05.000000000 -0700 +++ debian/rules 2006-09-24 11:14:32.000000000 -0700 @@ -14,7 +14,8 @@ awk '/Version:/ {print $$2}' | cut -d- -f 1) DEB_TAR_SRCDIR = icu/source -DEB_CONFIGURE_USER_FLAGS = --disable-samples --enable-static +DEB_CONFIGURE_USER_FLAGS = --disable-samples --enable-static \ + CONFIG_SITE=../../../config.site DEB_COMPRESS_EXCLUDE = html examples DEB_INSTALL_EXAMPLES_libicu36-dev = \ build-tree/$(DEB_TAR_SRCDIR)/samples/* --- config.site 1969-12-31 16:00:00.000000000 -0700 +++ config.site 2006-09-24 11:47:28.000000000 -0700 @@ -0,0 +1,7 @@ +# These trick the configure script into not linking anything with libpthread, +# while still enabling thread safety (it goes on to check for +# pthread_mutex_lock in libc, which is enough for what it actually needs). +# Should work correctly on all glibc-based systems. +ac_cv_lib_pthread_pthread_attr_init=no +ac_cv_search_pthread_mutex_destroy=no +ac_cv_lib_pthread_pthread_mutex_init=no
