I go for the manual:
http://www.yoctoproject.org/docs/1.8/dev-manual/dev-manual.html#adt-eclipse
I could compile this Yocto Project ADT Autotools Project "hello world"
It generates a lot of files and I am lost how to add more source files and headers.
I added a second c-file with a function "sub" and header and included the header in the hello world.c.
But I get linker problems and the second c file isn't get compiled. What do I have to do if the project gets bigger with more files ...? In the old times I added something to makefile, but I have two and both are crowded ...
make all
make all-recursive
make[1]: Entering directory `/home/user/ws/sp_test'
Making all in src
make[2]: Entering directory `/home/user/ws/sp_test/src'
../arm-poky-linux-gnueabi-libtool --tag=CC --mode=link arm-poky-linux-gnueabi-gcc -march=armv7-a -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a9 --sysroot=/home/user/yocto_microzed/tmp/sysroots/microzed-zynq7 -g -O0 --sysroot=/home/user/yocto_microzed/tmp/sysroots/microzed-zynq7 --sysroot=/home/user/yocto_microzed/tmp/sysroots/microzed-zynq7 -o sp_test sp_test-sp_test.o

sp_test-sp_test.o: In function `main':
/home/user/ws/spi_test/src/sp_test.c:40: undefined reference to `sub'
collect2: error: ld returned 1 exit status
The second issue is with qemu:
I get the message
Error: unknow fuile arg [path to my uImage]
This is the automatical generated config:
-e "source /home/user/yocto_microzed/tmp/environment-setup-cortexa9-vfp-neon-poky-linux-gnueabi;runqemu /home/user/yocto_microzed/tmp/deploy/images/microzed-zynq7/uImage /home/user/yocto_microzed/tmp/sysroots/microzed-zynq7 ;bash"
and here what can be found at this locations:
user@vb:~$ ll /home/user/yocto_microzed/tmp/deploy/images/microzed-zynq7/uImage

I hope someone can help a YOCTO 1.8 beginner.
