As an example, we will create camcv, a soft strongly inspired from raspistill. It will allow us later to modify source code and play with OpenCV.
- create a new folder in your home directory and copy all raspicam apps source code.
cd
mkdir camcv
cd camcv
cp /opt/vc/userland/host_applications/linux/apps/raspicam/* .
mv RaspiStill.c camcv.c
Perhaps a chmod is necessary (sudo chmod 777 camcv.c)
2. remove then content of CMakeLists.txt and replace with :
cmake_minimum_required(VERSION 2.8)
project( camcv )
SET(COMPILE_DEFINITIONS -Werror)
include_directories(/opt/vc/userland/host_applications/linux/libs/bcm_host/include)
include_directories(/opt/vc/userland/interface/vcos)
include_directories(/opt/vc/userland)
include_directories(/opt/vc/userland/interface/vcos/pthreads)
include_directories(/opt/vc/userland/interface/vmcs_host/linux)
add_executable(camcv RaspiCamControl.c RaspiCLI.c RaspiPreview.c camcv.c)
target_link_libraries(camcv /opt/vc/lib/libmmal_core.so /opt/vc/lib/libmmal_util.so /opt/vc/lib/libmmal_vc_client.so /opt/vc/lib/libvcos.so /opt/vc/lib/libbcm_host.so )
3. delete CMakeFiles directory if it exits
4. Compile & test
cmake .
make
./camcv -t 1000
5. [optional] Clean file. camcv.c is a long file with a lot of useless lines for us. All these following function could be delete (or commented). Remove of course all call to these functions in the remaining code.
static void dump_status(RASPISTILL_STATE *state)
static int parse_cmdline(int argc, const char **argv, RASPISTILL_STATE *state)
static void display_valid_parameters()
static MMAL_STATUS_T add_exif_tag(RASPISTILL_STATE *state, const char *exif_tag)
static void add_exif_tags(RASPISTILL_STATE *state)
static void store_exif_tag(RASPISTILL_STATE *state, const char *exif_tag)
The existing line default_status(&state); avoid you to parse command line using defaults parameters. Just add a line after this one :
state.filename=”foobar.jpg”;
Recompile and retest. Should work.
At this stage you should watch an old good movie with John Wayne.

I used to be suggested this blog by my cousin. I am no longer sure whether
or not this post is written by means of him as nobody else realize
such distinct approximately my difficulty. You are wonderful!
Thank you!
Hello all,
I have followed all the steps as mentioned above. But I am still getting the following error
/home/pi/camcv/RaspiTex.h:37:35: fatal error: interface/khronos/include/EGL/eglext_brcm.h: No such file or directory.
Compilation terminated.
I have gone through all the posts provided here. This issue was discussed earlier. i Followed rileyjenk solution for it but still getting the same error.
Searched out a lot but unable to find any solution.
Can someone please help!!
Edit RaspiTex.h on line 37 to read
#include “/opt/vc/userland/interface/khronos/include/EGL/eglext_brcm.h”
edit as needed for your file location. You will also likely want to edit line 38 (mmal.h include) to a similar location. Mine is:
#include “/opt/vc/userland/interface/mmal/mmal.h”
make[1]: CMakeFiles/Makefile2: No such file or directory

Can anyone help ?
I meet same problems,. Do u find ant solutions
Same problem here – any direction would be greatly appreciated
did you find the solution , i have the same problem here 😦
I have same problem, i need help!
…and another one bites the dust…
Solved this problem by adding to CMakeLists.txt this line:
SET(CMAKE_EXE_LINKER_FLAGS “-lpthread”)
But now I get the next reference problems: raspitex_set_defaults, raspitex_configure_preview_port, display_valid_parameters, parse_cmdline, dump_status, raspitex_init, raspitex_start, raspitex_capture, add_exif_tags, raspitex_stop, raspitex_destroy.
I have the same things. I go to the 5th step, delete functions and try to “make” one more time, but result is the same. I try it on raspberry pi B+, Raspbian OS:

same problem 😦 😦 did anyone find a solution yet?
Awesome I’m stuck at the same place as everyone else, why is it so hard to do this =( it looked so simple for him
hi, thx for sharing. i tired your cmakelist but it keep on report me:
CMake Error at CMakeLists.txt:19 (add_executable):
Cannot find source file:
gl_scenes/models.c
I have checked in gl_source, models.c is just there and i have no idea whats going wrong
Same problem here. any solution?
I’ve also encountered the same problem. Is there any solution?
“/usr/bin/ld: CMakeFiles/camcv.dir/camcv.c.o: undefined reference to symbol ‘sem_post@@GLIBC_2.4′”
I get the same error as this.
As I understang it, the reason is this:
This program needs Libc.
Raspbian is based on Debian which currently uses EGlibc.
I can’t see how we can compile this program without Libc.
Do we need to wait until Debian switches back to Libc, or is there a workaround?
I mean Glibc, not Libc

Check this to compile raspi camcv https://github.com/robidouille/robidouille/tree/master/raspicam_cv
This one is great but i was not able to do following steps.
Using the static library
Add the include path
-I$(HOME)/git/robidouille/raspicam_cv
Link with the raspicamcv library
-L$(HOME)/git/robidouille/raspicam_cv -lraspicamcv
Link with the userland libraries:
-L$(HOME)/git/raspberrypi/userland/build/lib -lmmal_core -lmmal -l mmal_util -lvcos -lbcm_host
how to do this step??? Do i need to add anything in CMakeLists.txt?
i failed this step(sudo make) and cannot find the solution , plx help !
Makefile:5 ../Makefile.include: no such file or directory
so i find in the directory /home/camcv/ ,
there isn’t any file named Makefile.include
There is only the file named Makefile which the line 5 is “include ../Makefile.include”
Hi, I was abe to compile raspicam_cv but still errors here while compiling camcv. Can anyone who succeeded to compile camcv display the values of the PATH variable here.
I resolved this problem.
Messages says “I can’t find the link to sem_*”.
the “sem_*” is the lib of pthread,
(c.f. http://askubuntu.com/questions/521706/error-adding-symbols-dso-missing-from-command-line-while-compiling-g13-driver)
In my case, this message was output
“CMakeFiles/camcv.dir/build.make:181: recipe for target ‘camcv’ failed” .
Around “CMakeFiles/camcv.dir/build.make:181” is
180 camcv: CMakeFiles/camcv.dir/link.txt
181 @$(CMAKE_COMMAND) -E cmake_echo_color –switch=$(COLOR) –red –bold “Linking CXX executable camcv”
182 $(CMAKE_COMMAND) -E cmake_link_script CMakeFiles/camcv.dir/link.txt –verbose=$(VERBOSE)
So I added “,-lpthread” end of “CMakeFiles/camcv.dir/link.txt”

Hello, i tried this list but at the end of compilation i get as
cc:error: “-lpthread”: no such file or directory
please help
https://thinkrpi.wordpress.com/2013/05/22/opencvpi-cam-step-3-create-your-own-project/
hello everybody
I compiled raspicam successfully
but as I compiled camcv, I got this error, what should I do?
/home/pi/camcv/RaspiTex.h:33:21: fatal error: EGL/egl.h: No such file or directory
compilation terminated.
I solved last probem but now I get this error:
libmmal_core.so not recognized
what would be the problem?
How did you solve the problem of EGL/egl.h?
Copying the content of /opt/vc/userland/interface/khronos/include to /usr/include should do the trick. Try:
sudo cp –r /opt/vc/userland/interface/khronos/include/* /usr/include
I changed the following lines in the file RaspiText.h and it worked:
#include
#include
But I also had to change the CMakeLists.txt to the ones proposed.
This were the lines to change in RaspiText.h:
#include \
#include \
I cant edit or delete my own coments. it doesnt show what I wrote. You just have to delete “EGL/” from the first two includes, leaving them just like “egl.h” and “eglext.h”
“…/usr/bin/ld: CMakeFiles/camcv.dir/gl_scenes/models.c.o: undefined reference to symbol ‘sqrtf@@GLIBC_2.4′…”
For anyone getting this message, it means the linker was unable to resolve the floating square root function used in models.c file. What you will need to do is to add “-lm” linker flag during compilation. I suggest adding it to the “-lpthread” linker flag already suggested by others in the line:
SET(CMAKE_EXE_LINKER_FLAGS “-lpthread -lm”)
That should take care of the problem and be able to compile successfully.
Worked out for me ! Thanks 🙂
I have a problem. I take this error message.

when I try to run ./camcv -t 1000
i get the following error
mmal: mmal_vc_component_create: failed to create component ‘vc.ril.camera’ (1:ENOEM)
mmal: Camera not detected. please check carefully the camera module is installed correctly
I tried everything, touch to remove clock skew checked raspistill and vid they work, enabled the raspicam using raspi-config but unable to detect the cause. please help.
urgently needed.
thank you!

Any idea ?
Hi I have same error, do u find ant solutions ???
HI! I’m new to all of this and I’m getting an error when entering the following command:
cp /opt/vc/userland/host_applications/linux/apps/raspicam/* .
mv RaspiStill.c camcv.c
cp: target ‘camcv.c’ is not a directory
Don’t know why it says that, can anyone please help me?
It’s two different commands. Firstly, enter the first one. Then enter the second one…
are you executing all that on the same line?
because mv RaspiStill.c camcv.c is only a commando to rename the file to camcv.c
And the error message says that camcv.c is not a directory, as if you are trying to copy all with the previous cp command.
Getting the following error when entering make
In file included from /home/pi/camcv/camcv.c:77:0:
/home/pi/camcv/RaspiTex.h:33:21: fatal error: EGL/egl.h: No such file or directory

I am on a Raspberry Pi 2 with NOOBs Raspian and finally got this to work after a long time of sorting through all these comments on errors people had and trying different things. Maybe this will help someone out.
I primarily used the method from 王毅博 and added “pthread” and “-lm” at the end of target_link_libraries. I ended up deleting the whole camcv folder and starting over a few times so I recommend deleting that folder and copying it fresh using “sudo” and “-r” in your cp command because otherwise it would not copy in the gl_scenes folder.
Process:
cd ~
mkdir camcv
//while in camcv folder
sudo cp -r /opt/vc/userland/host_applications/linux/apps/raspicam/* .
//Delete everything in CMakeLists.txt and add:
//Note the “pthread” and “-lm” at the end of target_link_libraries
cmake_minimum_required(VERSION 2.8)

Please check If you could help me out with this. I am trying to interface cam since 2 months now.
Warm Regards
Amit
I was able to compile it…………!!!!!!!
the issue was my the folder “userland” used here is named as “userland-master” so I changed the name at all the places and it worked. I could have renamed the folder itself but anyway now its compiled.
🙂
I am glad you figured it out!
Hey brad
i found error while copying
//copy RaspiTex.h and RaspiTexUtil.h file to the gl_scenes folder.
cp RaspiTex.h /gl_scenes/RaspiTex.h
cp: accessing ‘/gl_scenes/RaspiTex.h’: is not a directory
i do have directory named gl_scenes. please help. same happens with secong copy command.
Hey Kevin u can use the following syntax.
cd /opt/vc/
cp RaspiTex.h /gl_scenes
cp RaspiUtilTex.h /gl_scenes
I am not sure if u need ‘/’ as currently I am not having the hardware to test but I also faced the same issue and that got it solved. I am now stuck in the next step
https://thinkrpi.wordpress.com/2013/05/22/opencvpi-cam-step-4-link-with-opencv/
interfacing with open cv. I have already installed OpenCv 2.4.9. In that again you have to change this file.
Regards
Amit
Hello Amit, i tried what you have mentioned as follows
sudo su
cd /opt/vc/
cp RaspiTex.h /gl_scenes
error: no such file or directory
but still i’m unable to copy it, please help me out
YOU are a lifesaver! thank you!

Now change the lines 33 to 36 in RaspiTex.h as follows.

Then correct the code as mentioned in step 5 above. you would have to delete/comment few code parts in ‘camcv.c’.

remove their folder paths, sorry that I can’t copy paste the code. I tried it didn’t work 😦

i’m trying to test an example using the raspberry pi camera board with opencv the code is from https://github.com/robidouille/robidouille/blob/master/raspicam_cv/RaspiCamCV.c
when typying make i get the error : undefined reference to symbol ‘cvSaveImage’
i have the header that contain the fonction cvSaveImage when i d’ont use cvSaveImage it compile successfully plz help 🙂
how to do step 5 [optional] Clean file. camcv.c is a long file with a lot of useless lines for us. All these following function could be delete (or commented). Remove of course all call to these functions in the remaining code.

Hey, I have hit nearly every error and am now in a similar position as sparkgo. the error i’m seeing after i run make is:
/user/bin/ld: cannot find -llism
so, I am not sure what package i am supposed to download or what and haven’t found anything else through googling. The full outptut is:
Linking C executable camcv
/usr/bin/ld: cannot find -llism
collect2: error: ld return 1 exit status
CMakeFiles/camcv.dir/build.make242: recipe for target ‘camcv’ failed
make[2]: *** [camcv] Error 1

make[1]: *** [CMakeFiles/camcv.dir/all] Error 2

Any help would be appreciated greatly,
Thanks
I dont know if people are still attempting this but I have been working through this and got camcv to build after modifying the CMakeLists.txt file a bit. My problem is when i run the command ./camcv -t 1000 i get the following errors:
mmal: Unable to set JPEG restart interval
mmal: main: Failed to create encode component
mmal: Failed to run camera app. Please check for firmware updates.
Has anyone else seen this and fixed it? Can anyone please help? Thanks.
Anyone have an idea why i have this error message please?

The Userland repository has changed every year and the makefile is very confused. Like everyone else in this place, I’ve met with a lot of mistakes. Here are the CMakefilelists.txt working for me;
