hi!

I try to cross-compile OpenCV for arm as described in the tutorial and have the following problem: I get following error after starting make:

root@debian:/home/martin/OpenCVArm/opencv-2.4.10/platforms/linux/build# make [ 1%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/adler32.c.o [ 1%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/compress.c.o [ 2%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/crc32.c.o [ 3%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/deflate.c.o [ 3%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/gzclose.c.o [ 4%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/gzlib.c.o [ 4%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/gzread.c.o [ 5%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/gzwrite.c.o [ 5%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/inflate.c.o [ 6%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/infback.c.o [ 6%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/inftrees.c.o [ 7%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/inffast.c.o [ 7%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/trees.c.o [ 8%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/uncompr.c.o [ 9%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/zutil.c.o Linking C static library ../lib/libzlib.a Error running link command: No such file or directory make[2]: * [3rdparty/lib/libzlib.a] Fehler 2 make[1]: [3rdparty/zlib/CMakeFiles/zlib.dir/all] Fehler 2 make: ** [all] Fehler 2

When I start cmake I get the following warning: cmake -DCMAKE_TOOLCHAIN_FILE=../armgnueabi.toolchain.cmake../../.. -- Detected version of GNU GCC: 49 (409) -- Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR) -- Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) (Required is at least versio ...

Anyone an idea? Thanks in advance!

I found a workaround:

After running cmake and generating the make files, edit opencv/opencv/platforms/linux/<your_build_dir>/CMakeFiles/3.5.1/CMakeCCompiler.cmake and replace set(CMAKE_AR "CMAKE_AR-NOTFOUND") with set(CMAKE_AR "/usr/bin/arm-linux-gnueabi-ar")

Note that setting the variable CMAKE_AR in the cmake line (CMAKE_AR="/usr/bin/arm-linux-gnueabi-ar") does not work. Seems like this sets the flag to empty.

I had the same problem.

Make sure that the following line in your arm-gnueabi.toolchain.cmake file is pointing to the correct address

set(ARM_LINUX_SYSROOT /root/work/codesourcery/arm-2013.05 CACHE PATH "ARM cross compilation system root")
