Missing header files

[Nybon]

Hello.

I'm building mpp into a Qt program and facing difficulties while importing the necessary header files. I'm building my program on a Linux distribution and the media library struggles to find header files located in other folders of the library.

Here is a picture illustrating what I am talking about. My code finds every header file, but the header files can't find other header files that are not located in the same folder. As shown in the picture, _mpp-develop\mpp\base\mpp_bufslot.cpp is looking for _mpplog.h, but it crashes since it is not in the same folder.

So, what is actually the correct way of handling the library files? Where do I place the folders from this API?

The cmake script handled the include directories by include_directories in CMakeLists.txt

[Nybon]

I changed my build system to cmake and here is my CMakeLists.txt file. What should I add to my CMakeLists.txt?

[HermanChen]

include_directories(your_directory)

[Nybon]

I'm now able to find all the headers, but I am not able to use the functions. What should I write in my CMakeLists.txt to fix this?

[HermanChen]

You also need to add more source code. The mpp_packet is in mpp/base/

[Nybon]

This example https://github.com/WainDing/mpp_linux_cpp/blob/master/CMakeLists.txt imports the whole library with target_link_libraries(mpp_linux_demo mpp pthread drm).

Can I use something similar in my situation?

I added these lines to my CMakeLists.txt file: include_directories(inc) include_directories(utils) include_directories(osal/inc) include_directories(mpp/inc) add_subdirectory(mpp)

[HermanChen]

Yes, it is right.

[Nybon]

I am using target_link_libraries(mpp_linux_demo mpp pthread drm).

I have included the following directories: include_directories(inc) include_directories(utils) include_directories(osal/inc) include_directories(mpp/inc) include_directories(mpp/hal/inc) add_subdirectory(mpp)

And I am still getting the error messages shown in the picture above.

[HermanChen]

Sub-directory should be also added. The sub-diretory CMakeLists.txt should be recursively included.

[Nybon]

I have added: add_subdirectory(mpp) add_subdirectory(osal) add_subdirectory(utils) add_subdirectory(test) add_subdirectory(mpp-develop) add_subdirectory(hal) add_subdirectory(base) add_subdirectory(codec) add_subdirectory(mpp/legacy) add_subdirectory(mpp/hal) add_subdirectory(mpp) add_subdirectory(osal) add_subdirectory(test) add_subdirectory(utils) add_subdirectory(mpp/hal) add_subdirectory(mpp/base) add_subdirectory(mpp/codec) add_subdirectory(mpp/vproc) add_subdirectory(osal/test) add_subdirectory(mpp/legacy) add_subdirectory(mpp/hal/vpu) add_subdirectory(mpp/codec/rc) add_subdirectory(mpp/base/test) add_subdirectory(mpp/codec/dec) add_subdirectory(mpp/codec/enc) add_subdirectory(mpp/hal/dummy) add_subdirectory(mpp/hal/rkenc) add_subdirectory(mpp/vproc/iep) add_subdirectory(mpp/vproc/rga) add_subdirectory(mpp/hal/common) add_subdirectory(mpp/hal/vpu/common) add_subdirectory(mpp/vproc/iep/test)

But nothing new happens.

[HermanChen]

add_subdirectory is to add the CMakeLists.txt in the subdirectory. Use include_directories also to add include directory.

Dear @Nybon did you solve the problem? could you please share your experience?

I never got it to work, but I found another solution. The project contains samples that will run fine. Try editing the samples instead of building the whole thing from scrath. It may be a bit messy, but it will at least work. Please share a better way to do this if you find one. Remember to keep the same file positions!

I'm trying to make a simple and clear C++ example. let you know if I do.

dear @Nybon I finally could Make it and use Opencv frame as input frame. https://github.com/EhsanVahab/rockchip-mpp-encoder
