Dear Ferenc, The problem occurs during linking of nsthreadtest, which is a utility for testing and not needed for the operations of naviserver. Nevertheless, it should certainly work.... and it does work for me.
when i go to the directory naviserver/nsthread and issue there rm *.o rm nsthreadtest make i see /bin/rm -Rf libnsthread.so gcc -shared -O2 -fomit-frame-pointer -Wall -Wno-implicit-int -fPIC -pipe -m64 -I../include -I"/usr/local/ns/include" -DHAVE_CONFIG_H -L../nsthread -L../nsd -L../nsdb -o libnsthread.so error.o master.o memory.o mutex.o cslock.o rwlock.o reentrant.o sema.o thread.o tls.o time.o pthread.o fork.o signal.o winthread.o -L/usr/local/ns/lib -ltcl8.5 -ldl -lgcc_s -lieee -lm -Wl,--export-dynamic -L/usr/local/ns/lib -Wl,-rpath,:/usr/local/ns/lib gcc -O2 -fomit-frame-pointer -Wall -Wno-implicit-int -fPIC -pipe -m64 -I../include -I"/usr/local/ns/include" -DHAVE_CONFIG_H -c -o nsthreadtest.o nsthreadtest.c /bin/rm -Rf nsthreadtest gcc -L../nsthread -L../nsd -L../nsdb -o nsthreadtest nsthreadtest.o -lpthread libnsthread.so -L/usr/local/ns/lib -ltcl8.5 -ldl -lgcc_s -lieee -lm -Wl,--export-dynamic -L/usr/local/ns/lib -Wl,-rpath,:/usr/local/ns/lib i.e. the program "nsthreadtest" links correctly. Notice, that the default complile steps on my machine don't include as your case the option "-fvisibility=hidden". My Machine data: gcc version 4.6.2 20111027 (Red Hat 4.6.2-1) (GCC) Linux alice.wu-wien.ac.at 3.2.2-1.fc16.x86_64 #1 SMP Thu Jan 26 03:21:58 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ./configure --prefix=/usr/local/ns --enable-threads --with-tcl=/usr/local/ns/lib --enable-64bit Notice the following difference: library libnsthread.so (and all *.o components) built with -fvisibility=hidden $ nm libnsthread.so | fgrep Ns_Tls 0000000000002b20 t Ns_TlsAlloc 0000000000002c00 t Ns_TlsGet 0000000000002ba0 t Ns_TlsSet ibrary libnsthread.so (and all *.o components) built without -fvisibility=hidden $ nm libnsthread.so | fgrep Ns_Tls 0000000000004260 T Ns_TlsAlloc 0000000000004360 T Ns_TlsGet 00000000000042f0 T Ns_TlsSet You see, the external symbols are only included in the .so-file without the hidden visibility. The question is, where is the "-fvisibility=hidden" coming from. Have you added it manually to the Makefile? If so, why? -gustaf neumann Am 14.02.12 08:24, schrieb Kulcsár Ferenc: > Hello! > > When I compile naviserver-4.99.4 the following error occures: > > gcc -shared -O2 -fomit-frame-pointer -Wall -Wno-implicit-int -fPIC -pipe > -fvisibility=hidden -m64 -I../include -I"/home/feri/tanul/include" > -DHAVE_CONFIG_H -L../nsthread -L../nsd -L../nsdb -o libnsthread.so error.o > master.o memory.o mutex.o cslock.o rwlock.o reentrant.o sema.o thread.o tls.o > time.o pthread.o fork.o signal.o winthread.o -L/home/feri/tanul/lib > -ltcl8.6 -ldl -lgcc_s -lieee -lm -Wl,--export-dynamic > -L/home/feri/tanul/lib -Wl,-rpath,:/home/feri/tanul/lib > gcc -O2 -fomit-frame-pointer -Wall -Wno-implicit-int -fPIC -pipe > -fvisibility=hidden -m64 -I../include -I"/home/feri/tanul/include" > -DHAVE_CONFIG_H -c -o nsthreadtest.o nsthreadtest.c > /bin/rm -Rf nsthreadtest > gcc -L../nsthread -L../nsd -L../nsdb -o nsthreadtest nsthreadtest.o -lpthread > libnsthread.so -L/home/feri/tanul/lib -ltcl8.6 -ldl -lgcc_s -lieee -lm > -Wl,--export-dynamic -L/home/feri/tanul/lib -Wl,-rpath,:/home/feri/tanul/lib > nsthreadtest.o: In function `Pthread': > nsthreadtest.c:(.text+0x19): undefined reference to `Ns_TlsSet' > nsthreadtest.c:(.text+0x25): undefined reference to `Ns_MutexLock' > nsthreadtest.c:(.text+0x47): undefined reference to `Ns_CondWait' > nsthreadtest.c:(.text+0x5d): undefined reference to `Ns_MutexUnlock' > nsthreadtest.c:(.text+0x67): undefined reference to `Ns_MasterLock' > ...... > > The compilation environment is: > > $ uname -a > Linux archlap.aneder.bel 3.2.5-1-ARCH #1 SMP PREEMPT Tue Feb 7 08:34:36 CET > 2012 x86_64 Intel(R) Pentium(R) Dual CPU T2390 @ 1.86GHz GenuineIntel > GNU/Linux > Archlinux > > $ ./configure --prefix=/home/feri/tanul --enable-threads --enable-shared > --with-tcl=/home/feri/tanul/lib --enable-dependency-tracking > > $ make -v > GNU Make 3.82 > Built for x86_64-unknown-linux-gnu > > $ gcc -vhi > Using built-in specs. > COLLECT_GCC=gcc > COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.2/lto-wrapper > Target: x86_64-unknown-linux-gnu > Configured with: /build/src/gcc-4.6-20120120/configure --prefix=/usr > --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man > --infodir=/usr/share/info --with-bugurl=https://bugs.archlinux.org/ > --enable-languages=c,c++,ada,fortran,go,lto,objc,obj-c++ --enable-shared > --enable-threads=posix --with-system-zlib --enable-__cxa_atexit > --disable-libunwind-exceptions --enable-clocale=gnu --disable-libstdcxx-pch > --enable-libstdcxx-time --enable-gnu-unique-object --enable-linker-build-id > --with-ppl --enable-cloog-backend=isl --enable-lto --enable-gold > --enable-ld=default --enable-plugin --with-plugin-ld=ld.gold > --disable-multilib --disable-libssp --enable-checking=release > Thread model: posix > gcc version 4.6.2 20120120 (prerelease) (GCC) > > glibc-2.15 > > Any help is appreciated. > > TIA > > feri > > ------------------------------------------------------------------------------ > Keep Your Developer Skills Current with LearnDevNow! > The most comprehensive online learning library for Microsoft developers > is just $99.99!
