我在通过cygwin在windows上编译pjsip时遇到了麻烦。 我试图使用pjsip形式的android branc http://svn.pjsip.org/repos/pjproject/branches/projects/android/ 适用于Windows的Android NDK r8c。
当我尝试配置pjsip时输出。

任何人都可以告诉我该如何解决这个问题....

确保你在Windows上启动Cygwin作为管理员，这让我在没有这么做的时候有点挣扎^^

我设法克服了这个错误，但仍然没有设法编译pjsip。我切换到linux，所有的工作都应该...... [/ p>

如果你看一下config.log，你会看到这样的东西：
aconfigure：2841： /cygdrive/c/android-ndk-r9/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-gcc -I / cygdrive / c / android-ndk-r9 / platforms / android-18 / arch-arm / usr / include -I / cygdrive / c / android-ndk-r9 / platforms / android-18 / arch-arm / usr / include -nostdlib -L / cygdrive / c / android-ndk-r9 / platforms / android-18 / arch-arm / usr / lib / conftest.c -lc -lgcc＆gt;＆amp; 5
C：/android-ndk-r9/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin /../ LIB / GCC /臂-Linux的androideabi / 4.4.3 /../ ../../../arm-linux-androideabi/bin/ld.exe：找不到-lc
NDK的ld.exe正在寻找libc（在arch-arm / usr / lib /中），但它不喜欢cygwin路径。更改 configure-android 行
export LDFLAGS =“$ {LDFLAGS} -nostdlib -L $ {ANDROID_SYSROOT} / usr / lib /”
这样的事情：
export LDFLAGS =“$ {LDFLAGS} -nostdlib -Lc：/机器人-NDK-R9 /平台/机器人-18 /拱形臂/ usr / lib中/“
