Hi Sylvain,
I didn't realize it when you responded, but <sys/_types.h> is a toolchain problem, and you just nailed it. Cool:)
Early on, before it was pointed to me to use the Getting Started wiki, I used the src/README.building file, which is a normal practice for all unix developers/admins. When I couldn't find the gnuarm.com toolchain, I searched the web for ubuntu toolchains and found the linaro one, gcc-arm-linux-gnueabi, which doesn't provide <sys_types.h>. No dev version either:( So, when using that toolchain, I had to come up with the missing <sys/_types.h>, and the only one I could find was from vivado:(
Is there a point to my life's story? Just to pont out into how much problems one can get with the wrong README file. I realize that building procedure must be defined and maintained in 1 place, either the wiki or the README file. The wiki is a non standard unix location, but a more convenient one. I propose to fix the info in README.building, to avoid future issues. The fix can be as simple as "Prerequisite is the armel toolchain. Check the <wiki url> for installation"

Thx Sylvain,
For your fast response. This turned out not to be the problem, since I did several times make clean & make distclean, after I created the toolchain, before posting:) But your response helped, in that this isn't a usual problem. Therefore smt in my setup.
Turned out problem was in my CPPFLAGS include dir. Early on, I faced a few problems with missing include files. 1 in particular <sys/_types.h> was nowhere in my system other than in Xilinx vivado, under /gcc-arm-none-eabi/. Once I removed it from CPPFLAGS osmocom-bb compiled fine (with a few warnings)
Problem solved:)

I've been following the installation directions from the wiki, Getting Started. After generating the arm-none-eabi toolchain, I proceeded with make.
My guess is you first tried compiling without an arm toolchain installed and then installed the arm toolchain and didn't do a 'make clean' when retrying.
Cheers,
Sylvain
