Обсуждение: CVS tip compiler error with --enable-thread-safety
Hi, Platform Slackware linux 9.1/ Linux 2.6.4 I did a make distclean and ./configure --enable-thread-safety. The build aborted with following error messages make[4]: Leaving directory `/home/shridhar/postgresql/pgsql/src/port' gcc -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -Wmissing-declarations -DFRONTEND -I../../../src/interfaces/libpq -I../../../src/include -D_GNU_SOURCE -c -o initdb.o initdb.c rm -f exec.c && ln -s ../../../src/port/exec.c . gcc -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -Wmissing-declarations -DFRONTEND -I../../../src/interfaces/libpq -I../../../src/include -D_GNU_SOURCE -c -o exec.o exec.c gcc -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -Wmissing-declarations initdb.o exec.o -L../../../src/interfaces/libpq -lpq -L../../../src/port -Wl,-rpath,/usr/local/pgsql/lib -lz -lreadline -ltermcap -lcrypt -lresolv -lnsl -ldl -lm -lpgport -o initdb ../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_getspecific' ../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_once' ../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_key_create' ../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_setspecific' collect2: ld returned 1 exit status make[3]: *** [initdb] Error 1 make[3]: Leaving directory `/home/shridhar/postgresql/pgsql/src/bin/initdb' The relevant configure messages read ------------- checking whether pthreads work without any flags... no checking whether pthreads work with -Kthread... no checking whether pthreads work with -kthread... no checking for the pthreads library -llthread... no checking whether pthreads work with -pthread... yes ------------- Here is relevant portion of src/Makefile.global ------------- PTHREAD_CFLAGS = -pthread -D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS PTHREAD_LIBS = LIBS = -lz -lreadline -ltermcap -lcrypt -lresolv -lnsl -ldl -lm ------------- It worked after I manually added -lpthread to LIBS and did a make clean;make RegardsShridhar

Turns out I > wasn't using the thread libs as part of library creation. I updated anoncvs, the patch in src/port/Makefile is there but initdb still fails to compile. I suspect this is because in Makefile.global PTHREAD_LIBS is still blank. I need to add -lpthread these to get stuff working. However I could not figure out what create PTHREAD_LIBS in Makefile.global. Is there something else I should try? Shridhar

Config.log should show checks for a variety of thread flags, and it should add any ones that your compiler supports. I would look in there for a cause or email me the whole file offlist. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001+ If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania19073
