[200/300] Build your own Cross Compile toolchain - Shortcut

[xray]

mpfr and gmp compiled successfuly.

gcc is almost done. I have a little problem at make.

Code:

checking whether -lc should be explicitly linked in... no
checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[1]: *** [configure-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/usr/local/gcc-4.3'
make: *** [all] Error 2

Configure parameters are:

Code:

./configure --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --target=mips-linux-gnu --enable-threads --disable-libmudflap --disable-libssp --disable-libstdcxx-pch --with-arch=mips32r2 --with-float=hard --enable-mips-nonpic --enable-extra-sgxxlite-multilibs --with-gnu-as --with-gnu-ld --enable-languages=c,c++ --enable-shared --enable-symvers=gnu --enable-__cxa_atexit '--with-pkgversion=Sourcery G++ Lite 4.3-154' --with-bugurl=https://support.codesourcery.com/GNUToolchain/ --disable-nls --prefix=/opt/codesourcery/ --with-sysroot=/usr/local/mips-4.3/mips-linux-gnu/libc --with-build-sysroot=/usr/local/mips-4.3/mips-linux-gnu/libc --with-gmp=/usr/local/ --with-mpfr=/usr/local/ --disable-libgomp --enable-poison-system-directories --with-build-time-tools=/usr/local/mips-4.3/mips-linux-gnu/bin

maybe one of the parameters are incorrect.

any suggestions?

Finally i have compiled gcc crosscompiler also on x86 PC OS: Ubuntu 9.10. I will create a small howto for that also.

[xray]

my first test failed.

I tried to cross compile hello world.

Code:

#include <stdio.h>
main()
{
    (void) printf("Hello World\n");
    return (0);
}

but if i execute the binary compiled file

Code:

sh-3.00# ./h
sh: ./hello: Text file busy

compile command is simply: mips-linux-gnu-gcc hello.c -o hello

vaidyasr do you know what can be the problem?

You need to compile any .c files with the options as below
mips-linux-gnu-gcc -EL -march=74kc -fPIC hello.c -o hello

finally i've crosscompiled my first app: latest version of rsync. (3.0.7)

Thank you vaidyasr for your help.

Thank you vaidyasr for your help.

So, the v3.0.7 is working without any errors?

Hello

have you started to write the howto?

I would be interested as well

Thanks

Yes it is.

I will post it soon. My system is a little bit messed up... there are gigs of source code files i need to clean up and summarize the compile commands.

Hi,

I am also compiling under Ubuntu 9.10 but at the moment I am stucked.

AS I could not compile the gcc (got the same errors as xray on page 1) I tried to compile
a) gmp
error => checking for suitable m4... configure: error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons).

b) fmpr
error => configure: error: gmp.h can't be found, or is unusable.

I tried to compile with without parameter as stated by vaidyasr.

Any Idea someone ?

---

Ok, the gmp problem is solved by installing m4 !

Now I have still a problem with mpfr:

configure:25189: error: libgmp not found or uses a different ABI.

Or is it the wrong way to compile without parameters ?

Did you installed mpfr & gmp in native OS as I mentioned in page 1?

[Freebyter]

Yes, I tried it for this two onyl with ./configure.

Hello install os and platform native mpf and gmp package and add the path to --with-gmp and --with-mpfr switch.

[Freebyter]

it seems that it's long ago that I compiled some stuff......

The gmp and mpfr seemed to be ok now, but now the binutils part throws the following

Code:

Guys,
do you think we could focus our effort on getting openwrt
http://www.openwrt.org
support for SMP8643 ?
It would be wonderful to have a full cross compiling environment with lots and lots of applications available.

Hi Yellow,

Sounds like a very good idea! I'm currently working (professionally) with openwrt and will have a look to see if this is difficult to do.. Openwrt generates a complete flash or disk image containing a bootable linux kernel and file system. This flash image is normally programmed into the target hardware. It is a problem for the PCH devices, because it does not allow us to reprogram the flash . The only advantage would be to have a well defined cross compile environment and ability to build additional software easily. The cross compiled software needs to be copied manually to the PCH, but that should not keep you from not using openwrt.

Just my 2cents...

SoloHan.
