configure

Which path should I pass to the --prefix option when doing cross compiling: should I specify the path on my build machine or the path on the target platform? Suppose I build the code into /home/me/arm/build/target_fs/usr , after that I copy the files into my target platform where they will be located at /usr . Should I use --prefix=/home/me/arm/build/target_fs/usr or just --prefix=/usr and then make install DESTDIR=/home/me/arm/build/target_fs ? I thought that the --prefix is not the path for build but the path for running environment (i.e. the path on target platform). The answers here makes

I'm trying to remote debug an application running on arm9 So far I've been able to cross compile and execute gdbserver on my device. get gdb (7.2) sources and extract them ./configure --target=arm-none-linux-gnueabi --with-expat=/usr/local/lib/ make cd gdb/gdbserver ./configure --host=arm-none-linux-gnueabi make tftp gdbserver to my device run and connect via gdb to the device gdbserver "seems" to start correctly and attach itself to my helloworld application When I try to gdb to the remote server, I get "warning: Can not parse XML target description; XML support was disabled at compile time"

When running configure it fails with checking for leptonica... yes checking for pixCreate in -llept... no configure: error: leptonica library missing But I have leptonica 1.69 built (downloaded source and ran ./configure && make install ) Edit I think configure: error: leptonica library missing is a bit misleading, please note that it first says checking for leptonica... yes , and then fails on checking for pixCreate in -llept... no . So maybe the problem is not that the library is missing, but something else. I finally managed to make it compile, after reading this and this thread. The proper

I am running on an RHEL 6.x box, which of course has GCC 4.4 installed. I wish to have LLVM running on this machine. In order to do so, I must compile it from source. In order to do that , I need a more modern version of GCC. So, following the instructions , I have built GCC 4.8.2: [snip] % $PWD/../gcc-4.8.2/configure --prefix=$HOME/toolchains --enable-languages=c,c++ % make -j$(nproc) % make install I'm logged in as root, so $HOME/toolchains resolves to /root/toolchains . After satisfying prerequisites for LLVM, I'm ready to configure and build LLVM. root@dev06 /root/llvm-build # ~/llvm

I'm looking at all the options that can be run for the configure script provided with Qt. (specifically qt-everywhere-opensource-src-5.2.0). After considerable searching, I've determined this stuff is poorly documented at best so I was hoping I could get some help. When I look at the descriptions for prefix and sysroot configuration options: ~/qt-everywhere-opensource-src-5.2.0$ ./configure -help | grep "sysroot" -extprefix <dir> ... When -sysroot is used, install everything to <dir> , -sysroot <dir> ...... Sets <dir> as the target compiler's and qmake's sysroot and also sets pkg-config paths.
