I'm following this article to install qt for embedded linux on my host machine (which runs Ubuntu). So far, I successfully ./configure'd it but when I type "make" or "make install" it gives this error:
make: * No targets specified and no makefile found. Stop.
I'm a Linux newbie so I don't know if I'm missing obvious here, so I'd appreciate if you could help me.
Changing command line to this solved my problem. ./configure -embedded arm -xplatform qws/linux-arm-g++ -prefix \ /usr/local/qt -little-endian -webkit -no-qt3support -no-cups -no-largefile \ -optimized-qmake -no-openssl -nomake tools -qt-mouse-tslib -qt-kbd-linuxinput

I am trying to run RISC-V linux on Qemu, following the instruction: Running 64- and 32-bit RISC-V Linux on QEMU
I have downloaded and installed the RISC-V GNU compiller Toolchain
./configure --prefix=/opt/riscv
make linux
and when I execute the command:
make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- defconfig
I got the following error:
:~/Documents/riscv64-linux/linux$ make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- defconfig
*** Default configuration is based on 'defconfig'
scripts/Kconfig.include:39: compiler 'riscv64-unknown-linux-gnu-gcc' not found
make[1]: *** [scripts/kconfig/Makefile:73: defconfig] Error 1
make: *** [Makefile:602: defconfig] Error 2
Kindly, advice how can I fix this problem.
This is standart problem, try to type whereis riscv64-unknown-linux-gnu-gcc if it get nothing, try to type riscv64- and press tab, you should see necessary prefix you need paste after CROSS_COMPILE=. Also maybe you also need add PATH variable with path to riscv-toolchain's bin in ~/.bashrc or/and in ~/.profile.
Build own linux is a big task, maybe you should learn some manuals about toolchain and building linux.

Having a heck of a time trying to build CodeLite for an ARM-based Ubuntu Linux target. (Build instructions here: http://codelite.org/Developers/Linux). I get an error from CMAKE that says Could not locate GTK2. Looking in the CmakeLists.txt file I can see that this is a result of find_package(GTK2) failing to find GTK2. I think I have installed gtk according to what the CodeLite build instructions say to do using the command sudo apt-get install libgtk2.0-dev.
In terms of cmake, I don't understand what a "package" is. How would I [manually] locate this package on my filesystem and how do I get cmake to find it?
For my aarch64 ubuntu 17.04, the libraries and headers were under /usr/lib/aarch64-linux-gnu, so invoking cmake with them produced the correct build files:
cmake -DCMAKE_INCLUDE_PATH=/usr/lib/aarch64-linux-gnu/ -DCMAKE_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/ -DCMAKE_BUILD_TYPE=Release .. -DCOPY_WX_LIBS=1
I've seen some articles about how to compile and uses FFmpeg for Android.
These are 2 good examples - example1 and example2
Unfortunately, non off them, or others I found helped me. In those two examples a build_android.sh is created and configure the FFmpeg's configuraion file and call to make. Every time when I'm running the script I'm getting the following error:
c:\android\development\android-ndk-r9\sources\ffmpeg>sh build_android.sh
c:/android/development/android-ndk-r9/toolchains/arm-linux-androideabi-4.8/prebu
ilt/windows-x86_64/arm-linux-androideabi/bin/bin/arm-linux-androideabi-gcc is un
able to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user#ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

If someone encountered and solved this issue it'll be much appreciated!
After trying the suggested script I ran into a new problem that I couldn't solved, this is the output of the script:

Can you paste what's in your build_android.sh file which you've copied inside the FFmpeg directory?
I've got the same error when one of the variables defined at the start of the script where set incorrectly. Check to see if your NDK or SYSROOT or TOOLCHAIN variables are set to a valid path!
I've tried using the following steps and it worked for me:
1) Download FFmpeg
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
2) Create a file called build_android.sh inside the FFmpeg directory
cd ffmpeg; touch build_ffmpeg_for_android.sh;
3) Add the following content to the file
#!/usr/bin/env bash
NDK=$HOME/Software/Android/android-ndk-r10/
SYSROOT=$NDK/platforms/android-19/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
function build_one

./configure \

--disable-static \
--disable-doc \
--disable-ffmpeg \
--disable-ffplay \
--disable-ffprobe \
--disable-ffserver \

$ADDITIONAL_CONFIGURE_FLAG
make clean
make -j4
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS="-marm"
build_one
4) Make the script executable
chmod +x build_ffmpeg_for_android.sh
5) Start the build of FFmpeg for Android (ARM)
(run the script with Bash, i.e. /usr/bin/bash not /usr/bin/sh)
./build_ffmpeg_for_android.sh
I was getting the same errors as #powerX and I was able to solve the issue using a different method from #dZkF9RWJT6wN8ux.
Though I am using Ubuntu 13.10, I hope you find my answer helpful. With android NDK r9 and FFMPEG 2.2 "Muybridge" release, I was finally able to accomplish the third step entitled "Build FFMPEG" from #powerX example1 link: http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/
I finally fixed this by changing the SYSROOT variable in the build_android.sh file to point to ".../android-19/arch-arm" instead of .../android-9/arch-arm".
Hope this helps.
I am trying to compile Qt5. I download Qt 5.1 from here: download.qt-project.org/official_releases/qt/5.1/5.1.0/single/qt-everywhere-opensource-src-5.1.0.tar.gz. But after "make" command I get this error:
ssl/qsslsocket_openssl.cpp:1414: error: q_ssl_ctrl was not decleared in this scope
I can not find anything on Google. How can I fix it?
configure qt with builtin ssl or compile openssl yourself and add it to your libraries in configure. I attach a expample configure line (was for qt4.8 static commercial installer on msvc2008!)
configure -static -commercial -release -no-fast -qt-sql-sqlite -qt-sql-mysql -qt-zlib -mmx -3dnow -sse -sse2 -openssl-linked -script -scripttools -no-declarative -arch windows -no-style-cde -no-style-motif -no-style-cleanlooks -no-style-plastique -no-webkit -nomake examples -nomake demos -no-qt3support -no-phonon -no-multimedia -no-dbus -no-opengl -no-xmlpatterns -platform win32-msvc2008 -I mysql\include -L mysql\lib -l mysqlclient -l libmysql
make sure you have the development files of openssl v1.0.0 or greater installed.
or use qt internal version as described by Sebastian
I am new to linux or LFS. I am building LFS 7.3 on virtual machine. I use Ubuntu 12.10.
For unknown reason, I can't partition the hard drive using cfdisk, so I create partition while installing the OS. I change the $LFS to /home/lost+found (the new partition).
Other than that, I followed all the tutorial in the LFS book precisely and I have successfully installed until point 5.6 in the book.
Now I am stuck at installing the first Glibc-2.17.
I use the following command to configure:
../glibc-2.17/configure \
--prefix=/tools \
--host=$LFS_TGT \
--build=$(../glibc-2.17/scripts/config.guess) \
--disable-profile \
--enable-kernel=2.6.25 \
--with-headers=/tools/include \
libc_cv_forced_unwind=yes \
libc_cv_ctors_header=yes \
libc_cv_c_cleanup=yes
I've tried to install gawk, and the error message did change. But I still got the following error when configuring:
checking for .preinit_array/.init_array/.fini_array support... no
configure: error: Need linker with .init_array/.fini_array support.
user#user:/home/lost+found/glibc-build$
What is probably wrong?
your probably trying to use bad Compiler flags -- over optimization or -fPIC or some kind of SSP/ hardening . Try the default optimization flags and see if it compiles ok
echo $CFLAGS
echo $CXXFLAGS
echo $CPPFLAGS
and examine the configparm file in your glibc build folder for your specs
It seems I forgot some special configuration for 64-bit host. I tried to install again using ubuntu 32-bit and everything works fine.
