What must be filled in the ZLIB field to get the generation going?
I am using a linux PC, I have ZLIB installed already, got the below by running dpkg -L zlib1g-dev
Thanks,
G Kowshik
It’s not same context but may be you can try this
please, give information as text, no useless screenshots, ty.
then, weren’t you trying to cross-compile something ? you probably cannot use your (host) system libs for this. in that case, rather use the BUILD_zlib flag, so it will also cross-compile 3rdparty libs
Hi,
I was able to get the generation done by making changes as below
I then went ahead to build/ folder and ran “make” command and I am getting the following errors
make -s

Thankstry to delete build folder and rerun cmake
I did try that couple of times, didn’t help.
hmm, that’s a compiler problem, it does not know, what a Mutex is
still cross-compiling ?
Hi berak,
yes I am trying to cross-compile it to cortex-r5 platform by using the arm-none-eabi-gcc compiler which I got from the ARM’s official website. Also I am little confused when you said “Compiler doesn’t know what a mutex is?” How is this a compiler attribute? I think It’s a cpp implementation that should be present. Correct me if wrong.
Thanks
and, does it support posix threads ?
exactly, as a part of the std libs, this compiler supports
How do I verify that please? I found on internet where I can run this command arm-none-eabi-g++ -xc -E -v - to see with what tags the compiler is built and I see the flag --disable-threads in the below log, Is this a problem? 
if yes, how do I fix it?
Using built-in specs.
