Package: libtool Version: 2.2.6a-1 Severity: normal Tags: patch
libtool2.2.6a, when run under zsh, adds bogus directories to linker lines: /usr/local/bin/zsh ../libtool --tag=CC --mode=link gcc -g -O2 -module -thread-safe -version-info 6:0:0 -no-undefined -Wl,--version-script,../libclamunrar_iface/libclamunrar_iface.map -o libclamunrar_iface.la -rpath /usr/local/lib/elf unrar_iface.lo libclamunrar.la -lz libtool: link: gcc -shared .libs/unrar_iface.o -Wl,-rpath -Wl,/tmp/clamav-0.95rc1/libclamav/.libs -Wl,-rpath -Wl,/usr/local/lib/elf ./.libs/libclamunrar.so /usr/local/bin -lz -Wl,--version-script -Wl,../libclamunrar_iface/libclamunrar_iface.map -Wl,-soname -Wl,libclamunrar_iface.so.6 -o .libs/libclamunrar_iface.so.6 /usr/local/bin: file not recognized: File format not recognized Notice that /usr/local/bin got added to the linker line. See https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1434 for more details, I have reproduced the bug running the attached libtool under zsh on Debian, I had /usr/lib/ccache added to the linker line (which is my first entry in $PATH) This happens because libtool has this code around line 5898 in ltmain.sh: for deplib in $dependency_libs; do case $deplib in -L*) path="$deplib" ;; *.la) ... sets path ... ;; esac case " $deplibs " in *" $path "*) ;; *) deplibs="$path $deplibs" ;; However "path" is not assigned a value when deplib is something like '-lz'. When run under bash this is not a problem, $path will be the empty string, however when run under zsh, it will be the first component of $PATH, which is a directory, and will cause link failure. This can be fixed by applying the patch below: index b36c4ad..554c74a 100755 --- a/ltmain.sh +++ b/ltmain.sh @@ -5944,6 +5944,7 @@ func_mode_link () path="-L$absdir" fi ;; + *) path="";; esac case " $deplibs " in *" $path "*) ;; -- System Information: Debian Release: 5.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.28.3 (SMP w/4 CPU cores; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages libtool depends on: ii autotools-dev 20080123.2 Update infrastructure for config.{ ii bcc [c-compiler] 0.16.17-3 16-bit x86 C compiler ii cpp 4:4.3.2-3 The GNU C preprocessor (cpp) ii file 4.26-2 Determines file type using "magic" ii gcc [c-compiler] 4:4.3.2-3 The GNU C compiler ii gcc-3.4 [c-compiler] 3.4.6-9 The GNU C compiler ii gcc-4.1 [c-compiler] 4.1.2-25 The GNU C compiler ii gcc-4.2 [c-compiler] 4.2.4-6 The GNU C compiler ii gcc-4.3 [c-compiler] 4.3.3-4 The GNU C compiler ii libc6-dev [libc-dev] 2.9-2 GNU C Library: Development Librari Versions of packages libtool recommends: ii libltdl7-dev 2.2.6a-1 A system independent dlopen wrappe Versions of packages libtool suggests: ii autoconf 2.61-8 automatic configure script builder ii automake [automaken] 1:1.10.1-3 A tool for generating GNU Standard ii automake1.7 [automaken] 1.7.9-9 A tool for generating GNU Standard pn gcj <none> (no description available) pn gfortran | fortran95-compiler <none> (no description available) pn libtool-doc <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
