Interesting development... Although my gcc version is supposed to be 4.1.2, when I found libstdc++.a, it was symlink'd from a 4.1.2 dir to a 4.1.1 dir. Anyway, I tried recompiling again using "CXXFLAGS=-L/usr/lib/gcc/i386-redhat-linux/411" and although the error is formatted different than before, it seems to be the same issue. Maybe there's more info in the error now that might help? libIpcIo.a(IpcIoFile.o): In function `Ipc::Atomic::WordT<int>::get() const': IpcIoFile.cc:(.text._ZNK3Ipc6Atomic5WordTIiE3getEv[Ipc::Atomic::WordT<int>::get() const]+0x15): undefined reference to `__sync_fetch_and_add_4' libIpcIo.a(IpcIoFile.o): In function `Ipc::Atomic::WordT<int>::operator+=(int)': IpcIoFile.cc:(.text._ZN3Ipc6Atomic5WordTIiEpLEi[Ipc::Atomic::WordT<int>::operator+=(int)]+0x14): undefined reference to `__sync_add_and_fetch_4' libIpcIo.a(IpcIoFile.o): In function `Ipc::Atomic::WordT<int>::swap_if(int, int)': IpcIoFile.cc:(.text._ZN3Ipc6Atomic5WordTIiE7swap_ifEii[Ipc::Atomic::WordT<int>::swap_if(int, int)]+0x1b): undefined reference to `__sync_bool_compare_and_swap_4' libIpcIo.a(IpcIoFile.o): In function `Ipc::Atomic::WordT<int>::operator-=(int)': IpcIoFile.cc:(.text._ZN3Ipc6Atomic5WordTIiEmIEi[Ipc::Atomic::WordT<int>::operator-=(int)]+0x14): undefined reference to `__sync_sub_and_fetch_4' ipc/.libs/libipc.a(ReadWriteLock.o): In function `Ipc::Atomic::WordT<int>::operator++(int)': ReadWriteLock.cc:(.text._ZN3Ipc6Atomic5WordTIiEppEi[Ipc::Atomic::WordT<int>::operator++(int)]+0x21): undefined reference to `__sync_fetch_and_add_4' ipc/.libs/libipc.a(ReadWriteLock.o): In function `Ipc::Atomic::WordT<int>::operator--(int)': ReadWriteLock.cc:(.text._ZN3Ipc6Atomic5WordTIiEmmEi[Ipc::Atomic::WordT<int>::operator--(int)]+0x21): undefined reference to `__sync_fetch_and_sub_4' ipc/.libs/libipc.a(StoreMap.o): In function `Ipc::Atomic::WordT<unsigned char>::get() const': StoreMap.cc:(.text._ZNK3Ipc6Atomic5WordTIhE3getEv[Ipc::Atomic::WordT<unsigned char>::get() const]+0x21): undefined reference to `__sync_fetch_and_add_1' ipc/.libs/libipc.a(PageStack.o): In function `Ipc::Atomic::WordT<unsigned int>::swap_if(unsigned int, unsigned int)': PageStack.cc:(.text._ZN3Ipc6Atomic5WordTIjE7swap_ifEjj[Ipc::Atomic::WordT<unsigned int>::swap_if(unsigned int, unsigned int)]+0x27): undefined reference to `__sync_bool_compare_and_swap_4' ipc/.libs/libipc.a(PageStack.o): In function `Ipc::Atomic::WordT<unsigned int>::fetchAndAnd(unsigned int)': PageStack.cc:(.text._ZN3Ipc6Atomic5WordTIjE11fetchAndAndEj[Ipc::Atomic::WordT<unsigned int>::fetchAndAnd(unsigned int)]+0x20): undefined reference to `__sync_fetch_and_and_4' collect2: ld returned 1 exit status libtool: link: rm -f ".libs/squidS.o" make[3]: *** [squid] Error 1 make[3]: Leaving directory `/root/work/squid-3.2.1/src' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/work/squid-3.2.1/src' make[1]: *** [all] Error 2 make[1]: Leaving directory `/root/work/squid-3.2.1/src' make: *** [all-recursive] Error 1 ----- Original Message ----- From: "Amos Jeffries" <squid3@xxxxxxxxxxxxx> To: "Jeff Gerard" <mysubscriptions@xxxxxxx> Cc: squid-users@xxxxxxxxxxxxxxx Sent: Tuesday, 28 August, 2012 11:47:38 PM Subject: Re: Compile error Squid 3.2.1 On 29/08/2012 2:24 a.m., Jeff Gerard wrote: > Thanks for the suggestions. Unfortunately this goes beyond my understanding of compiling as I have no idea as to how to tell if I have multiple libc libraries installed, and if I do, how to account for it using CXXFLAGS. You should be able to locate it/them with the command line "locate libstdc++.a". Add '-L' followed by the directory path where the library .a file is found to the CXXFLAGS variable. For example it is probably: ./configure CXXFLAGS=" -L/usr/lib" Amos > ----- Original Message ----- > From: "Amos Jeffries" <squid3@xxxxxxxxxxxxx> > To: squid-users@xxxxxxxxxxxxxxx > Sent: Tuesday, 28 August, 2012 4:50:44 AM > Subject: Re: Compile error Squid 3.2.1 > > On 28/08/2012 6:25 a.m., Jeff Gerard wrote: >> I am looking for help in determining why my compile will not work. >> >> I have been running into the following errors during compile: >> >> /root/work/squid-3.2.1/src/ipc/../../src/ipc/AtomicWord.h:47: undefined reference to `__sync_fetch_and_add_4' >> ipc/.libs/libipc.a(PageStack.o):/root/work/squid-3.2.1/src/ipc/../../src/ipc/AtomicWord.h:47: more undefined references to `__sync_fetch_and_add_4' follow >> ipc/.libs/libipc.a(PageStack.o): In function `Ipc::Atomic::WordT<unsigned int>::swap_if(unsigned int, unsigned int)': >> /root/work/squid-3.2.1/src/ipc/../../src/ipc/AtomicWord.h:38: undefined reference to `__sync_bool_compare_and_swap_4' >> ipc/.libs/libipc.a(PageStack.o): In function `Ipc::Atomic::WordT<int>::swap_if(int, int)': >> /root/work/squid-3.2.1/src/ipc/mem/PageStack.cc:88: undefined reference to `__sync_bool_compare_and_swap_4' >> ipc/.libs/libipc.a(PageStack.o): In function `Ipc::Atomic::WordT<int>::operator+=(int)': >> /root/work/squid-3.2.1/src/ipc/../../src/ipc/AtomicWord.h:31: undefined reference to `__sync_add_and_fetch_4' > For some reason your system header files are defining those __sync > symbols but the libc which is being linked against does not contain them. > > Please check your system for multiple libc libraries and ensure only one > version is installed (latest by version is best) or that CXXFLAGS is > passed arguments to identify the latest one explicitly. > >> collect2: ld returned 1 exit status >> libtool: link: rm -f ".libs/squidS.o" >> make[3]: *** [squid] Error 1 >> make[3]: Leaving directory `/root/work/squid-3.2.1/src' >> make[2]: *** [all-recursive] Error 1 >> make[2]: Leaving directory `/root/work/squid-3.2.1/src' >> make[1]: *** [all] Error 2 >> make[1]: Leaving directory `/root/work/squid-3.2.1/src' >> make: *** [all-recursive] Error 1 >> >> I am running this on Fedora Core 6 (have been running 3.1.20 with no issue) and gcc version is 4.1.2 > 3.1 series contains no SMP support or atomic operations. > > AMos
