Building RPM 4.0.4 from Source (Available Mutex?)
Last modified: 2008-05-01 11:38:01 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461) Description of problem: Trying to compile the source pacakge results in a failure due to incorrect Mutex type. I am not able to find any working Mutex to use for the StrongARM architecutre. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Get the latest pacakge 2. Open it up in a directory 3. Using Intrinsync's StrongArm enviroment: Run: export CXX=gcc export CC=gcc export ac_cv_sizeof_char=1 \ ac_cv_sizeof_unsigned_char=1 \ ac_cv_sizeof_short=2 \ ac_cv_sizeof_unsigned_short=2 \ ac_cv_sizeof_int=4 export ac_cv_sizeof_long=4 \ ac_cv_sizeof_long_long=8 \ ac_cv_sizeof_unsigned_long_long=8 \ ac_cv_sizeof_float=4 export ac_cv_sizeof_double=8 \ db_cv_alignp_t=set \ db_cv_alignp_t="unsigned int" export db_cv_fcntl_f_setfd=yes \ db_cv_sprintf_count=no \ db_cv_mutex="ia64/gcc-assembly" (I tried, x86/gcc-assembly, ALPHA/gcc-assembly, ia64/gcc-assembly, and others) export PATH=/root/Intrinsyc/arm-linux/bin:/root/Intrinsync/bin:$PATH ./configure --build=i386-linux --host=arm-linux --disable-aio Actual Results: Different combinations of the same error: /tmp/ccsmWE1E.s: Assembler messages: /tmp/ccsmWE1E.s:85: Error: bad instruction `xchg1 r3=[r4,#0],r1' make: *** [mut_tas.lo] Error 1 ../mutex/mut_tas.c: In function `__db_tas_mutex_lock': ../mutex/mut_tas.c:109: inconsistent operand constraints in an `asm' Expected Results: Getting the binaries?! :) Additional info: I downloaded the latest stable and development package off www.rpm.org (4.0.4)
You're on an arm platform, you're gonna need arm assembly voo-doo for a test-and-set mutex, no other platform's assembly language will do. Try looking in libpthread for arm specific mutexes, or ask an ARM developer on an arm-specific mailing list for the Right Thing To Do. Sorry, ARM is not a platform that's available to me, so I can't undertake a fix flying blind, as it were. Please reopen this bug if you have a patch for rpm on arm, however, I'll be happy to integrate a known good patch
Wow, well Debian has been nicer with their reply, and they have one of their own, so I guess I will just move there. If you will be kind enough to look into their's available here: http://ftp.de.debian.org/debian/dists/woody/main/binary-arm/pool/main/r/rpm/
Wrong URL: http://ftp.debian.org/debian/pool/main/r/rpm/
Thanks for the pointer. Here's what I find + +The rpm source also includes (but is not built using) a copy of db3, which has +a BSD license (db/LICENSE in the source tree). + as it's db[34], not rpm, what needs the arm patch.
And I do not see an arm mutex patch at ../../d/db3/db3_3.2.9.patch.gz (relative to the URL you've given me). Again, if there's a patch, I'll be happy to integrate into the db-4.0.14 code within rpm. I have no way of testing still ...
Here's the arm asm voo-doo AFAICT: However your path of least resistance is gonna be to configure the internal db-4.0.14 with --enable-posixmutexes to use the mutexes from libpthread. Have fun with Debian however, I still cannot test the above. int __pthread_spin_lock (pthread_spinlock_t *lock) { unsigned int val; do asm volatile ("swp %0, %1, [%2]" : "=r" (val) : "0" (1), "r" (lock) : "memory"); while (val != 0); return 0; } weak_alias (__pthread_spin_lock, pthread_spin_lock) int __pthread_spin_trylock (pthread_spinlock_t *lock) { unsigned int val; asm volatile ("swp %0, %1, [%2]" : "=r" (val) : "0" (1), "r" (lock) : "memory"); return val ? EBUSY : 0; } weak_alias (__pthread_spin_trylock, pthread_spin_trylock) int __pthread_spin_unlock (pthread_spinlock_t *lock) { return *lock = 0; } weak_alias (__pthread_spin_unlock, pthread_spin_unlock)
