you need to create a proper CMake toolchain file for cross compilation.
for example, you can take the toolchain file and CMake from current android NDK and cross compile with that. The standard help for cmake https://cmake.org/cmake/help/v3.14/manual/cmake-toolchains.7.html might help here, as the issue is mostly setting the correct variables so that CMake searches the correct folders for your libraries. regards Armin On 5/6/19 7:34 AM, Kaushal Gupta via FreeRDP-devel wrote: > Hi, > There is no clarity on cross-compiling freeRDP for arm platform. > I compile this in ubuntu 16.04 for desktop within arm-linux-gnueabihf-gcc. > and compile zlib, openssl with arm-linux-gnueabihf-gcc too; but could not > succeed with configuration even. > > #cmake . -DZLIB_INCLUDE_DIR=/.....zlib//include > -DZLIB_LIBRARY=/.....zlib/lib -DOPENSSL_ROOT_DIR=/...../openssl > -DLIB_EAY=/.....openssl/lib/libcrypto.a > -DSSL_EAY=....../openssl/lib/libssl.a -DCMAKE_INSTALL_PREFIX=./freerdp-arm > -DWITH_CUPS=OFF -DWITH_ALSA=OFF -DWITH_FFMPEG=OFF -DWITH_GSTREAMER_1_0=OFF > -DWITH_XINERAMA=OFF -DWITH_XV=OFF -DWITH_XRANDR=ON -DWITH_NEON=OFF > -DCMAKE_BUILD_TYPE=Debug -DGlib_INCLUDE_DIR=/....../libc/usr/include > -DGlibConfig_INCLUDE_DIR=/..../libc/usr/include > -DGlib_LIBRARY=/..../arm-linux-gnueabihf/libc/lib > -DGobject_LIBRARY=/...../arm-linux-gnueabihf/libc/lib > -DBUILS_SHARED_LIBS=OFF > > getting below error msg while cofiguring. > FREERDP_VERSION=2.0.0-rc4 > -- Git Revision b9718af > -- Performing Test Wno-unused-result > -- Performing Test Wno-unused-result -
