[ECOS] Problem while building the ecos Application with newer version gcc tool set.

[ECOS] Problem while building the ecos Application with newer version gcc tool set.

[jameshq]

Hi all :
   While I am using the newer version of gcc, g++, insight, binutils.
binutils-2.12.1.tar.bz2
gcc-3.0.4.tar.bz2
gc-g++-3.0.4.tar.bz2
insight-5.2.tar.bz2

I can have the tool set(ARM E7T) built and get the ecos library(default)
successfully but when I tried to compile my application: hello.c as:

arm-elf-gcc -I/e7t/e7t_install/include
hello.c -L/e7t/e7t_install/lib -Ttarget.ld -nostdlib

I got the following error message:

/tools/H-I686~1/bin/../lib/gcc-lib/arm-elf/3.0.4/../../../../arm-elf/bin/ld:
can
not find libsupc++.a
collect2: ld returned 1 exit status

Did I miss something? Thanks for your help.

regards!
james

The library should be in your gcc install directory:

$ find . -name libsupc++.a
./arm-elf/lib/thumb/libsupc++.a
./arm-elf/lib/libsupc++.a

Is it there?

pass -v to gcc so you see exactly what ld is doing. Does it have the
paths correct?

It is very strange I don't have this library installed. Is it installed
while confinguring? I just got "libgcc.a". how can I solve this problem?
Thanks a lot!

The make install would of installed it. When you built gcc, what
languages did you make? I could imagine that if you only build a C
compiler and not a C++ compiler, maybe it did not build this library.

I followed exactly the same as on the web:
http://sources.redhat.com/ecos/tools/win-arm-elf.html

Configure GCC, ensuring that the GNU Binary Utilities are at the head of the
PATH:
    PATH=/tools/H-i686-pc-cygwin/bin:$PATH ; export PATH
    mkdir -p /tmp/build/gcc
    cd /tmp/build/gcc
    /src/gcc/gcc-2.95.2/configure --target=arm-elf \
      --prefix=/tools \
      --exec-prefix=/tools/H-i686-pc-cygwin \
      --with-gnu-as --with-gnu-ld --with-newlib \
      -v 2>&1 | tee configure.out

Build and install GCC:
    make -w all-gcc install-gcc \
      LANGUAGES="c c++" 2>&1 | tee make.out

I redo it again but still can't get the library. Is it because I am using
the GCC 3.0.4?

Thanks a lot!

Search the mailing list archives for "cannot find libsupc++.a" and you'll find 
the answer.  I think someone posted the answer again just yesterday.
It involves removing libsupc++ from the target.ld file.

No, it doesn't (at least not if you want to write C++ code). It involves
building and installing libsupc++:
