gdb的教程建议使用'gcc -g'进行编译,以使用调试符号编译程序.

但是,我想调试用make编译的程序.如何指示make使用调试符号进行编译？

谢谢.

如何使用Android NDK的独立工具链构建libsdl？我不能使用标准的ndk-build,因为我必须与现有的构建系统集成.

我知道我可能必须分别在我的PATH和CC环境变量中放置交叉编译器的路径和名称,但我认为还有许多其他事情需要完成 - 例如SSE和3DNow可能需要禁用(目标架构是ARM)等

这是我到目前为止:

$ HOSTCONF=arm-eabi-linux
$ TOOLCHAIN=$HOME/android/toolchain
$ export ARCH=armv7-a
$ export SYSROOT=$TOOLCHAIN/sysroot
$ export PATH=$PATH:$TOOLCHAIN/bin:$SYSROOT/usr/local/bin
$ export CROSS_COMPILE=arm-linux-androideabi
$ export CC=${CROSS_COMPILE}-gcc
$ export CXX=${CROSS_COMPILE}-g++
$ export CFLAGS="-DANDROID -mandroid -fomit-frame-pointer --sysroot $SYSROOT -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb"
$ export CXXFLAGS=$CFLAGS
$ ./configure --host=$HOSTCONF --build=i686-pc-linux-gnu  --with-sysroot=$SYSROOT --prefix=$SYSROOT/usr/local --disable-joystick
$ make
$ make install

我正在尝试用Android NDK独立编译器工具链构建一些东西,但是我收到了这个错误:

任何人都可以告诉我为什么这可能会失败:

afeder@ubuntu:~/android/toolchain/sysroot$ ls $PKG_CONFIG_SYSROOT_DIR/usr/local/lib/pkgconfig/mozjs185.pc
/home/afeder/android/toolchain/sysroot/usr/local/lib/pkgconfig/mozjs185.pc

afeder@ubuntu:~/android/toolchain/sysroot$ pkg-config mozjs185 --cflags
Package mozjs185 was not found in the pkg-config search path.
Perhaps you should add the directory containing `mozjs185.pc'
to the PKG_CONFIG_PATH environment variable
No package 'mozjs185' found

根据pkg-config的手册页,/usr/local/lib/pkgconfig应该是默认搜索路径之一.
