gcc & g++

Hi all
I’ve downloaded a toolchain containing gcc and g++ in it , after installing angstrom from narcissus I’ve tried to compile the toolchain so
as I’ve read from somepages in internet I went to this folder
/usr/local/angstrom/arm and entered the following command
sh ./environment-setup
but nothing happend and just the command line jumped to another line as below :

root@beagleboard:/usr/local/angstrom/arm# sh ./environment-setup
root@beagleboard:/usr/local/angstrom/arm#

and I thought that gcc and g++ were installed by this command so I ran this code to compile my opencv example to see if I can see a simple image
histogram or not

root@beagleboard:/# g++ -o Hist Hist.cpp pkg-config --libs opencv pkg-config --cflags opencv
but the output was :
sh: g++: not found
!!!
I’m sure that my toolchain contains gcc and g++ because I searched the arm folder and found them , but I think that they are not installed .
any suggestion about this problem(my compile command is wrong or …) ?

Rahim,

Type gcc and then double tab after running the ./environment-setup, the angstrom-cross-binaries have a different name rather than just pure 'gcc' or 'g++'.

Regards,
Jack.

The arm cross compiler command would be arm-angstrom-linux-gnueabi-g++ or arm-angstrom-linux-gnueabi-gcc

Whoops! My mistake, it is indeed pre-fixed - not post-fixed as I earlier stated! *arm-angstrom-linux-gnueabi-g++* is correct.

`any suggestion about this problem(my compile command is wrong or …) ?```

If you see gcc and g++ in your toolchain, they are probably linked to the files I mentioned above. I would recommend that you use the full name as the native compiler uses gcc and g++ so you will end up with x86 code and not arm code. Just make sure the compiler bin folder is in your PATH.

Regards,

John

Good spot Koen. You can also do this

source environment-setup

Make sure you are using the correct environment-setup file. I installed
Angstrom in my home folder so my environment-setup file is in
~/.oe/environment-setup so here is the command I use:

source ~/.oe/environment-setup

hi…
I have developed a toolchain and now i want to develop a native compiler for Beagleboard-xM, hope u can help me…

Maddy, you are a tough guy! Why do you need our help?

Dear Maxim,
I know that I am tough guy… no one takes birth with the full knowledge… and if u want to learn than what goes in asking for help from anyone in the universe… now whether people help here or not it depends on thm… Even u would have taken help from various places… and every linux developer is a tough guy… so, u r also…
