Hi. I am having getting log4cplus compile with Solaris Studio 12.3 compiler using Libtool 2.4.2, Autoconf 2.69 and Automake 1.12. The problems I am having is that despite configuration with --with-pic no -KPIC or -fPIC option is being passed to the compiler. (...some time passes...) I am not sure whose bug is this anymore. I have reduced the problem to the -v option that I was passing to the compiler, which was itself added by detection by configure.in. First the output configure script shows the problem: checking for /opt/solarisstudio12.3/bin/cc option to produce PIC... -KPIC -DPIC checking if /opt/solarisstudio12.3/bin/cc PIC flag -KPIC -DPIC works... yes checking if /opt/solarisstudio12.3/bin/cc static flag -Bstatic works... yes checking if /opt/solarisstudio12.3/bin/cc supports -c -o file.o... yes checking if /opt/solarisstudio12.3/bin/cc supports -c -o file.o... (cached) yes checking whether the /opt/solarisstudio12.3/bin/cc linker (/usr/bin/ld -m elf_x86_64) supports shared libraries... yes checking dynamic linker characteristics...

(cached) no checking whether the /opt/solarisstudio12.3/bin/CC linker (/usr/bin/ld -m elf_x86_64) supports shared libraries... yes As you can see above, for C compiler, the PIC support is detected fine. But for C++ compiler it says no. If I remove the -v option detection and the option is not present on the command line then PIC supports gets correctly detected for C++ compiler as well. Here is the interesting part from config.log showing the "result: no" (full log is attached): configure:17042: checking for /opt/solarisstudio12.3/bin/CC option to produce PIC configure:17049: result: -KPIC -DPIC configure:17057: checking if /opt/solarisstudio12.3/bin/CC PIC flag -KPIC -DPIC works configure:17075: /opt/solarisstudio12.3/bin/CC -c -L/lib/x86_64-linux-gnu/ -L/usr/lib/x86_64-linux-gnu/ -mt=yes -O -v -library=stlport4 -library=Crun -D_REENTRANT -KPIC -DPIC -DPIC conftest.cpp >&5 ### CC: Note: NLSPATH = /opt/solarisstudio12.3/prod/bin/../lib/locale/%L/LC_MESSAGES/%N.cat:/opt/solarisstudio12.3/prod/bin/../../lib/locale/%L/LC_MESSAGES/%N.cat ### command line files and options (expanded): ### -c -L/lib/x86_64-linux-gnu/ -L/usr/lib/x86_64-linux-gnu/ -mt=yes -O3 -v -library=Crun,stlport4 -D_REENTRANT -xcode=pic32 -DPIC -DPIC conftest.cpp /opt/solarisstudio12.3/prod/bin/ccfe -xarch=amd64 -D__SUNPRO_CC=0x5120 -D__unix -D__unix__ -Dlinux -D__linux -D__linux__ -D__gnu__linux__ "-D__builtin_expect(e,x)=e" -D__x86_64 -D__x86_64__ -D__amd64 -D__amd 64__ -D_LP64 -D__LP64__ -D__BUILTIN_VA_STRUCT -Dunix -D_REENTRANT -D__SUN_PREFETCH -D__SUNPRO_CC_COMPAT=5 -I-xbuiltin -I/opt/solarisstudio12.3/prod/lib/compilers/rtlibs/usr/include -I/opt/solarisstudio12.3/p rod/include/CC/stlport4 -I/opt/solarisstudio12.3/prod/include/CC -I/opt/solarisstudio12.3/prod/include/cc -D_REENTRANT -DPIC -DPIC -ptf /tmp/ccfe.1335561892.25089.04.%1.%2 -ptx /opt/solarisstudio12.3/prod/bi n/CC -ptk "-c -mt=yes -O3 -v -library=stlport4 -library=Crun -D_REENTRANT -xcode=pic32 -DPIC -DPIC " -compat=5 -instlib=/opt/solarisstudio12.3/prod/lib/stlport4/amd64/libstlport.a -xdbggen=no%stabs+dwarf2+us edonly -xF=%none -xbuiltin=%default -pic -xldscope=global -xivdep=loop -xdepend -O3 conftest.cpp -o /tmp/ccfe.1335561892.25089.01.ir -s /tmp/ccfe.1335561892.25089.02.sd 2> /tmp/ccfe.1335561892.25089.03.err /opt/solarisstudio12.3/prod/bin/iropt -Qy -O3 -fstore -xarch=sse2 -m64 -xchip=generic -xcache=generic -fsimple=0 -fstore -depend -mt -k -xbuiltin=%default -I -xprefetch=auto,explicit -xprefetch_level=1 -xpre fetch_auto_type=no%indirect_array_access -xvector=simd -F -o /tmp/iropt.1335561892.25089.05.ir -is /tmp/ccfe.1335561892.25089.02.sd /tmp/ccfe.1335561892.25089.01.ir 2> /tmp/iropt.1335561892.25089.06.err rm /tmp/ccfe.1335561892.25089.01.ir /opt/solarisstudio12.3/prod/bin/ir2hf -Qy -O3 -xbuiltin=%default -m64 /tmp/iropt.1335561892.25089.05.ir /tmp/ccfe.1335561892.25089.02.sd /tmp/ir2hf.1335561892.25089.07.hf rm /tmp/ccfe.1335561892.25089.02.sd rm /tmp/ccfe.1335561892.25089.03.err rm /tmp/iropt.1335561892.25089.05.ir rm /tmp/iropt.1335561892.25089.06.err /opt/solarisstudio12.3/prod/bin/ube -Qy -verbose -iropt -O3 -fstore -comdat -m64 -xarch=sse2 -xchip=generic -xcache=generic -fsimple=0 -ZW -fstore -PIC -xbuiltin=%default -xprefetch=auto,explicit -xprefetch_ level=1 -xthreadvar=dynamic -mt -fbe /opt/solarisstudio12.3/prod/bin/fbe -ipo conftest.o -S /tmp/ube.1335561892.25089.08.s /tmp/ir2hf.1335561892.25089.07.hf rm /tmp/ir2hf.1335561892.25089.07.hf /opt/solarisstudio12.3/prod/bin/fbe -Qy -xarch=amd64 -xchip=generic -warn=%none -o conftest.o /tmp/ube.1335561892.25089.08.s rm /tmp/ube.1335561892.25089.08.s configure:17079: $? = 0 configure:17092: result: no -- VZ
