Indeed, /opt/csw/gcc4/lib/gcc/sparc-sun-solaris2.8/4.0.2/../../../libgcc_s.so is a 32 bit library. I wonder how it get linked in a 64 bit generation; normally, the /opt/csw/gcc4/lib/spqrcv9/libgcc_s.so is used in this case and it is a 64 bit library.
Can you give me a minimal C program which manifest this behaviour?
Please re-execute your example using the -v switch and attach the output thus obtained.
Also, I gather from your example that it is extracted from a libtool based link phase. Am I correct? |

Hi,
1. I am new to unix world now.... last i did was 20 years ago....so am quite rusty.... I am trying to build a package (an IBM mainframe emulator)..... here is the link for entire source as ditsributed by the developers: http://www.hercules-390.org/hercules-3.03.1.tar.gz. [^] this will allow you to run configure and make yourself.
2. Attached is the log from Configure and make.... that i ran. http://solutionint.com/configure-and-make.log..... [^] pls also notice that it did not detect libiconv whereas gcc3 sucessfuly detects that.
Thanks for your help. |

Sorry, i forgot to attach the output with -v option, here it is:

1118 is not the same case: here we have C, there we have C++. The same example as in 1118 works when on a C program. I\'m continuing the investigations. |

1118 is similar, it\'s just that C++ causes inclusion of -lgcc_s for a trivial program. Try:
$ echo \"main(){}\" > source.c
$ /opt/csw/gcc4/bin/gcc -m64 source.c -lgcc_s
ld: fatal: file /opt/csw/gcc4/lib/gcc/sparc-sun-solaris2.8/4.0.2/../../../libgcc_s.so: wrong ELF class: ELFCLASS32
ld: fatal: File processing errors. No output written to a.out
collect2: ld returned 1 exit status
and note the example above uses lgcc_s
ld is finding /opt/csw/gcc4/lib/libgcc_s.so.1 before /opt/csw/gcc4/lib/sparcv9/libgcc_s.so.1 |

Using:
LD_OPTIONS=\'-Dfiles,libs,detail\' gcc -v -m64 t.c -lgcc_s -o t
and
LD_OPTIONS=\'-Dfiles,libs,detail\' g++ -v -m64 txx.cc -o txx
I found the culprit: a missing symbolic link. To link 64 bit objects you must do, as root, the following:
cd /opt/csw/gcc4/lib/sparcv9
ln -s libgcc_s.so.1 libgcc_s.so
installf CSWgcc4core /opt/csw/gcc4/lib/sparcv9/libgcc_s.so
installf -f CSWgcc4core
I\'ll put this on the package\'s main page and will correct in the package for the next release, probably 4.0.3
Note that the deep reason of this is an incorrect specification file --- /opt/csw/lib/gcc/sparc-sun-solaris2.8/4.0.2/specs --- and the correction that I\'ll made available in the future packages will use this.
