how to compile C program for c6x-linux?

Shiqiang Lee

Hi,

I have built the linux kernel and filesystem as "Linux-c6x_2.0_Release" describes. And write the nand.bin to NAND Flash(My target is EVMC6678L). All include the mcsdk-demo and syslink examples seems to be OK.

But I am not clear enough about how to compile my own C program? For example, a "helloworld" program.

In $LINUX_C6X_TOP_DIR/linux-c6x-project/hello, there is an example, but when I run ./mk after edit some variables, I get the "can't find lc" "can't find crt1.o" msgs. In both $LINUX_C6X_TOP_DIR/opt/gcc-c6x and $LINUX_C6X_TOP_DIR/sdk dirs, I don't find those libs of executable tool.

Then, how could I compile the hello example successful?

By the way, what the difference of above two toolchains?(opt/gcc-c6x and sdk/bin)

Anyone could give me some help?

Thanks.

I have solved this problem, just compile with command "c6x-uclinux-gcc -o hello.out hello.c" will be OK.

And don't use the default mk file.

That is correct. You can export the PATH to include opt/gcc-c6x/bin, and compile with c6x-uclinux-gcc. Default mk file was written for CGT tools before linux-c6x-2.0 moved to gcc, and has not been updated.
