Hello,
I am trying to build LMDB libraries from source on SUSE Linux using gcc 4.7.2 to try for an experimental project at work. I am getting some build errors. I see pthread.h and libpthread.{a/so} installed in /usr/include and /usr/lib64, respectively. But I do not see these functions in the header file or in the library. Maybe the pthread library version is old. I am not sure. I tried searching on the web, but I was not able to understand how to install a different version of the pthread library (it seems to come packaged with the OS?). I do not have admin rights so I would try installing in my local area. Can someone please advise on things I can try to resolve this issue? Thank you for your time and help. (P.S. I had built LMDB successfully on a Mac OS X machine (home computer) without any issues) $ make gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized -c mdb.c mdb.c: In function ‘mdb_mutex_failed’: mdb.c:9827:4: warning: implicit declaration of function ‘pthread_mutex_consistent’ [-Wimplicit-function-declaration] gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized -c midl.c ar rs liblmdb.a mdb.o midl.o ar: creating liblmdb.a gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized -fPIC -c mdb.c -o mdb.lo mdb.c: In function ‘mdb_mutex_failed’: mdb.c:9827:4: warning: implicit declaration of function ‘pthread_mutex_consistent’ [-Wimplicit-function-declaration] gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized -fPIC -c midl.c -o midl.lo gcc -pthread -shared -o liblmdb.so mdb.lo midl.lo gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized -c mdb_stat.c gcc -pthread -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -Wuninitialized mdb_stat.o liblmdb.a -o mdb_stat liblmdb.a(mdb.o): In function `mdb_env_setup_locks': /nfs/pdx/proj/dt/tctg03/pgupta6/lmdb-mdb.master/libraries/liblmdb/mdb.c:4642: undefined reference to `pthread_mutexattr_setrobust' liblmdb.a(mdb.o): In function `mdb_mutex_failed': /nfs/pdx/proj/dt/tctg03/pgupta6/lmdb-mdb.master/libraries/liblmdb/mdb.c:9827: undefined reference to `pthread_mutex_consistent' collect2: error: ld returned 1 exit status make: *** [mdb_stat] Error 1 My environment is as follows: $ more /etc/SuSE-release SUSE Linux Enterprise Server 11 (x86_64) VERSION = 11 PATCHLEVEL = 2 $ uname -a Linux 3.0.101-0.7.29.1.8482.4.PTF-default #1 SMP Tue May 5 16:00:34 UTC 2015 () x86_64 x86_64 x86_64 GNU/Linux |
