6 years ago That particular file is present in the target root system:
manuel@vader:~/src/Commander-Genius/build$ find /opt/rpi_root/usr/include -name stdlib-bsearch.h /opt/rpi_root/usr/include/arm-linux-gnueabihf/bits/stdlib-bsearch.h
...but it seems the buildsystem does not look for headers in that arm-linux-gnueabihf subdirectory. How can I convince it to do so, to look in the arm-linux-gnueabihf subdir too?
You say "target root". Can it be that it isn't available in the host root ? Have you rsynced /usr and /lib to the host system ?
I'm trying to cross-build a project that uses CMAKE. I am using a toolchain file for this. First I export the path with the arm cross-compiler:
PATH=$PATH:$HOME/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin `
Then I have created a toolchain file with these contents (the target system usr,lib,and opt directories from Raspbian are in /opt/rpi_root):
SET(CMAKE_SYSTEM_NAME Linux) SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER arm-bcm2708hardfp-linux-gnueabi-gcc) SET(CMAKE_CXX_COMPILER arm-bcm2708hardfp-linux-gnueabi-g++)
SET(CMAKE_FIND_ROOT_PATH /opt/rpi_root)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
Then I use cmake like this, passing the toolchain file to it:
cmake -DUSE_SDL2=yes -DBUILD_TARGET=LINUX -DCMAKE_BUILD_TYPE=Release -DOGG=no -DTREMOR=NO -DOPENGL=no -DREFKEEN=no -DCMAKE_TOOLCHAIN_FILE=~/src/raspi.cmake ..
It results on the buildsystem to find everything alright, apparently:
manuel@vader:~/src/Commander-Genius/build$ cmake -DUSE_SDL2=yes -DBUILD_TARGET=LINUX -DCMAKE_BUILD_TYPE=Release -DOGG=no -DTREMOR=NO -DOPENGL=no -DREFKEEN=no -DCMAKE_TOOLCHAIN_FILE=~/src/raspi.cmake .. -- The C compiler identification is GNU 4.7.1 -- The CXX compiler identification is GNU 4.7.1 -- Check for working C compiler: /home/manuel/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-gcc -- Check for working C compiler: /home/manuel/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /home/manuel/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-g++ -- Check for working CXX compiler: /home/manuel/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-g++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- cotire 1.7.6 loaded. -- Preparing the Build-System for Commander Genius -- Setting SYSTEM_DATA_DIR to /usr/local/ -- Found PkgConfig: /usr/bin/pkg-config (found version "0.28") -- checking for one of the modules 'sdl2' -- Using shared SDL Version 2 for Commander Genius -- Boost version: 1.55.0 -- checking for one of the modules 'SDL2_image>=2.0.0' -- Using shared SDL Version 2 for Commander Genius -- DOSBox-Fusion: OFF -- Internal Downloader: OFF -- Refkeen for Keen Dreams: no -- CXX target CGeniusExe cotired. -- CPACK_PACKAGE_VERSION = 1.9.1-Beta -- Build system is prepared.

BUT when I try to build it, there are problems with header file location:
[ 14%] Building CXX object src/graphics/CMakeFiles/graphics.dir/effects/CColorMerge.cpp.o In file included from /usr/include/SDL2/SDL_stdinc.h:40:0, from /usr/include/SDL2/SDL_main.h:25, from /usr/include/SDL2/SDL.h:32, from /home/manuel/src/Commander-Genius/src/graphics/effects/CColorMerge.h:14, from /home/manuel/src/Commander-Genius/src/graphics/effects/CColorMerge.cpp:8: /opt/rpi_root/usr/include/stdlib.h:760:34: fatal error: bits/stdlib-bsearch.h: No such file or directory compilation terminated. src/graphics/CMakeFiles/graphics.dir/build.make:54: recipe for target 'src/graphics/CMakeFiles/graphics.dir/effects/CColorMerge.cpp.o' failed make[2]: * [src/graphics/CMakeFiles/graphics.dir/effects/CColorMerge.cpp.o] Error 1 CMakeFiles/Makefile2:1213: recipe for target 'src/graphics/CMakeFiles/graphics.dir/all' failed make[1]: * [src/graphics/CMakeFiles/graphics.dir/all] Error 2 Makefile:136: recipe for target 'all' failed make: *\ [all] Error 2
That particular file is present in the target root system:
manuel@vader:~/src/Commander-Genius/build$ find /opt/rpi_root/usr/include -name stdlib-bsearch.h /opt/rpi_root/usr/include/arm-linux-gnueabihf/bits/stdlib-bsearch.h
...but it seems the buildsystem does not look for headers in that arm-linux-gnueabihf subdirectory. How can I convince it to do so, to look in the arm-linux-gnueabihf subdir too?
