c++ - Cross compile on Fedora 18 for Centos 6.4 -


i working on project, uses classes c++11 standard, on fedora 18 machine , want deploy on centos 6.4 server.

i able resolve loader errors except libc , libc++ versions, glibc_2.11, glibcxx_3.4.15 , on fedora machine glibc_2.14 , @ least glibcxx_3.4.17 respectively.

is possible tell compiler compile/link server versions or older compatible versions of libraries?

when run ldd executable 

./executable: /lib64/libc.so.6: version `glibc_2.14' not found (required ./executable) ./executable: /usr/lib64/libstdc++.so.6: version `glibcxx_3.4.15' not found (required ./executable)

thanks in advance!

instead of manually copying libraries separate directory set chroot contaiing centos build env, using mock , epel-6-x86_64 config.

use yum in mock chroot install packages want (e.g. qt) , build in there, ensure code uses centos 6 libs installed in chroot, not rest of packages on fedora os.

update:

when i'm using mock chroot building gcc this:

# need these steps once setup chroot mock -r fedora-19-x86_64 --init mock -r fedora-19-x86_64 --install yum mock -r fedora-19-x86_64 --shell 'mkdir -p /builddir/gcc/src /builddir/gcc/build' su -c 'mount --bind $path_to_gcc_sources /var/lib/mock/fedora-19-x86_64/root/builddir/gcc/src' # enter root password mock -r fedora-19-x86_64 --shell # in chroot yum install gmp-devel mpfr-devel libmpc-devel flex autogen su - mockbuild cd gcc/build ../src/configure --prefix=/builddir/gcc/install ... etc. ...

for purpose you'd replace fedora-19 epel-6

the bind mount means don't need have gcc sources in chroot, can use existing copy in normal filesystem. see http://gcc.gnu.org/wiki/installinggcc info on building gcc

once install gcc in chroot can use build own programs package them centos.

to go chroot again later:

mock -r fedora-19-x86_64 --shell su - mockbuild

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
