this script puts the tools in $HOME/mips_toolchain/bin so modify the plasma tools Makefile to point at this location.

<<<<<<<<< got rid of those ld PIC errors ... woohoo !!>>>>>>

bootldr builds OK .... :-)

hi Paul thanks for your script, i've tried it in ubuntu 9.04 32bits, but unfortunately it doesn't work, in the folder mips_toolchain/bin/ i don't have mips-elf-gcc

i have just : mips_toolchain/bin/mips-elf-addr2line mips_toolchain/bin/mips-elf-ar mips_toolchain/bin/mips-elf-as mips_toolchain/bin/mips-elf-c++filt mips_toolchain/bin/mips-elf-ld mips_toolchain/bin/mips-elf-nm mips_toolchain/bin/mips-elf-objcopy mips_toolchain/bin/mips-elf-objdump mips_toolchain/bin/mips-elf-ranlib mips_toolchain/bin/mips-elf-readelf mips_toolchain/bin/mips-elf-size mips_toolchain/bin/mips-elf-strings mips_toolchain/bin/mips-elf-strip mips_toolchain/bin/tclsh8.4

during the compilation of the script there was no error

so what should i do?

thanks

Hi Ali, your gcc may not have built if the gcc you are building with cannot find the path to the elf executables. Put an exit command just after the following lines in the script

cd $INSTALL_DIR/build ./$GCC_VER/configure --prefix=$INSTALL_DIR --target=$TARGET-elf --enable-languages=c make make install exit

This will stop the script just after gcc make and install. Examine the output to see if gcc appears to build and install OK. There could be something wrong with the path. Unfortunately I dont do error checking so the script will continue even if there is an error in one of the stages. Let me know how you go.

thanks Paul for your respond

here what I got at the end off gcc but i dont know what should I do correct it

Your problem is a Ubuntu GCC issue .... see here

https://wiki.kubuntu.org/CompilerFlags

Apparently the solution is to remove the -O2 flags from the CFLAGS options for GCC in the script.

CFLAGS="-g -O2 -mabi=32" ASFLAGS=$CFLAGS

find the part of the script above and remove the -O2

... I dont have ubuntu so you will have to test.

Paul.
