UNRESTRICTED / ILLIMITÉE

Hi Mark,

Thanks for the prompt reply.

I did have the correct links, but I found this out with some tinkering it was actually a missing g++ library that solved my problem.

I had to install g++-multilib, that solved the libstdc++ link issue.

My three builds built, but I know have a separate issue. Please review it to determine if I should post it to another subject.

Which looks complete.

Good.

Ls x86:

/usr/local/epics.bak/base-3.14.12.3/bin$ ls linux-x86

convertRelease.pl  filterWarnings.pl  makeBaseExt.pl     mkmf.pl

cvsclean.pl        fullPathName.pl    makeIncludeDbd.pl  munch.pl

dos2unix.pl        installEpics.pl    makeMakefile.pl    replaceVAR.pl

expandVars.pl      makeBaseApp.pl     makeTestfile.pl    useManifestTool.pl

Missing a lot of tools here.

Please tell me your thoughts.

Thanks so much,

Are you sure you have installed both the 64-bit and 32-bit versions of the system library libstdc++.so?

Here are the files on my Fedora system:

7233436    0 lrwxrwxrwx   1 root     root           37 Apr 10  2012 /usr/lib/gcc/x86_64-redhat-linux/4.6.3/libstdc++.so -> ../../../../lib64/libstdc++.so.6.0.16

7233434    0 lrwxrwxrwx   1 root     root           31 Apr 10  2012 /usr/lib/gcc/x86_64-redhat-linux/4.6.3/32/libstdc++.so -> ../../../../libstdc++.so.6.0.16

Note that there are both 64-bit and 32-bit versions of that library.

Do you find both 64-bit and 32-bit versions of libstdc++.so on your system?

Subject: EPICS BASE-3.14.12.3 32-bit Binaries on 64-bit host Machine

OFFICIAL USE ONLY / À USAGE EXCLUSIF

Hello,

I will start will giving some of the environment details:

Host Machine:

Ubuntu 12.04 (3.13.0-71-generic kernel) x86_64

I am building IOC’s for 64 and 32-bit machines; I am also cross compiling for ARM (Raspberry Pi), with crosstools-ng.

The build is successful for 64 bit binaries and the 32-bit cross compile, but I keep getting an error for x86:

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.6/libstdc++.so when searching for -lstdc++

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.6/libstdc++.a when searching for -lstdc++

/usr/bin/ld: cannot find -lstdc++

collect2: ld returned 1 exit status

make[3]: *** [libCom.so.3.14] Error 1

make[3]: Leaving directory `/usr/local/epics.bak/base-3.14.12.3/src/libCom/O.linux-x86'

make[2]: *** [install.linux-x86] Error 2

make[2]: Leaving directory `/usr/local/epics.bak/base-3.14.12.3/src/libCom'

make[1]: *** [libCom.install] Error 2

make[1]: Leaving directory `/usr/local/epics.bak/base-3.14.12.3/src'

make: *** [src.install] Error 2

I have the gcc-multilib package, and lib32, and I followed this advice:

base/configure/os/CONFIG_SITE.linux-x86.Common:

# T.S, 2006/09/05

# add -m32 so we create 32-bit code when

# executing on 64-bit machine with EPICS_HOST_ARCH=linux-x86

ARCH_DEP_CFLAGS+=-m32

ARCH_DEP_CXXFLAGS+=-m32

ARCH_DEP_LDFLAGS+=-m32

Thanks you in advance for your help,

Lee
