Bug#655432: clang unusable on armel and armhf, link failures
Package: clang
Followup-For: Bug #655432
Dear Maintainer,
In order to help track down this bug, I have tried an older version of clang.
My test program compiles successfully with clang 2.9-16 and libllvm2.9
2.9+dfsg-4. I will see if I can further pinpoint the change that may have
caused this bug.

Bug#655432: clang unusable on armel and armhf, link failures
Package: clang
Version: 3.0-1
Followup-For: Bug #655432
Dear Maintainer,
It appears that this bug first appears in 3.0-1 on the armel platform.
The changelog notes the removal of some debian specific patches which related
to debian multi-arch search paths. It seems likely that the upstream patches
which replaced the debian ones differed slightly from the debian clang 2.9-16
patches in some manner significant for the armel architecture. Please let me
know if I can be of further assistance in squashing this bug.
Trying to compile the test.c file fails at linking in a manner similar
to that reported above for clang 3.0-5.

Bug#655432: clang unusable on armel and armhf, link failures
Package: clang Version: 3.0-5 Followup-For: Bug #655432 Dear Maintainer, I can confirm this bug for the armel architecture. I too am unable to link a simple test program. Mine differed slightly from the original reporter in that my program was a simple Hello World test instead of containing an empty main function. My system is primarily testing, but the clang and llvm packages are from unstable. I was expecting the test program to be compiled and linked, but clang failed during linking in a manner similar to the original reporter. dpkg -l | grep llvm ii libllvm3.0 3.0-5 Low-Level Virtual Machine (LLVM), runtime library dpkg -S crti.o libc6-dev: /usr/lib/arm-linux-gnueabi/crti.o me@mybox:/tmp$ clang test.c -v Debian clang version 3.0-5 (tags/RELEASE_30/final) (based on LLVM 3.0) Target: arm-unknown-linux-gnueabi Thread model: posix /usr/bin/clang -cc1 -triple armv4t-unknown-linux-gnueabi -S -disable-free -disable-llvm-verifier -main-file-name test.c -mrelocation-model static -mdisable-fp-elim -mconstructor-aliases -target-abi aapcs-linux -target-cpu arm7tdmi -mfloat-abi soft -target-feature +soft-float-abi -target-linker-version 2.22 -momit-leaf-frame-pointer -v -resource-dir /usr/bin/../lib/clang/3.0 -fmodule-cache-path /var/tmp/clang-module-cache -internal-isystem /usr/local/include -internal-isystem /usr/bin/../lib/clang/3.0/include -internal-externc-isystem /usr/include/arm-linux-gnueabi -internal-externc-isystem /usr/include -ferror-limit 19 -fmessage-length 80 -fno-signed-char -fgnu-runtime -fobjc-runtime-has-arc -fobjc-runtime-has-weak -fobjc-fragile-abi -fdiagnostics-show-option -fcolor-diagnostics -o /tmp/test-1AcllR.s -x c test.c clang -cc1 version 3.0 based upon llvm 3.0 hosted on arm-unknown-linux-gnueabi ignoring nonexistent directory /usr/bin/../lib/clang/3.0/include ignoring nonexistent directory /usr/bin/../lib/clang/3.0/include ignoring duplicate directory /usr/local/include ignoring duplicate directory /usr/include/arm-linux-gnueabi ignoring duplicate directory /usr/include/arm-linux-gnueabi ignoring duplicate directory /usr/include/arm-linux-gnueabi ignoring duplicate directory /usr/include ignoring duplicate directory /usr/include/arm-linux-gnueabi ignoring duplicate directory /usr/include ignoring duplicate directory /usr/include #include ... search starts here: #include ... search starts here: /usr/local/include /usr/include/arm-linux-gnueabi /usr/include /usr/include/clang/3.0/include/ /usr/lib/gcc/arm-linux-gnueabi/4.6/include/ /usr/lib/gcc/arm-linux-gnueabi/4.6/include-fixed/ End of search list. /usr/bin/as -o /tmp/test-4BKE8B.o /tmp/test-1AcllR.s /usr/bin/ld -X --hash-style=both --build-id --eh-frame-hdr -m armelf_linux_eabi -dynamic-linker /lib/ld-linux.so.3 -o a.out crt1.o crti.o /usr/lib/gcc/arm-linux-gnueabi/4.6/crtbegin.o -L/usr/lib/gcc/arm-linux-gnueabi/4.6 -L/usr/lib/gcc/arm-linux-gnueabi/4.6/../../.. -L/lib -L/usr/lib /tmp/test-4BKE8B.o -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/arm-linux-gnueabi/4.6/crtend.o crtn.o /usr/bin/ld: cannot find crt1.o: No such file or directory /usr/bin/ld: cannot find crti.o: No such file or directory clang: error: linker command failed with exit code 1 (use -v to see invocation) -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (650, 'testing'), (600, 'unstable') Architecture: armel (armv5tel) Kernel: Linux 3.2.0-1-orion5x Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages clang depends on: ii libc62.13-26 ii libclang-common-dev 3.0-5 ii libffi5 3.0.10-3 ii libgcc1 1:4.6.2-12 ii libllvm3.0 3.0-5 ii libstdc++6 4.6.2-12 ii libstdc++6-4.6-dev 4.6.2-12 Versions of packages clang recommends: ii llvm-3.0-dev none ii python2.7.2-10 clang suggests no packages. -- no debconf information clang_test_strace.log Description: inode/empty
