我在通过 cygwin 在 Windows 上编译 pjsip 时遇到问题。我尝试使用 pjsip 形式的 android branc http://svn.pjsip.org/repos/pjproject/branches/projects/android/ 和适用于 Windows 的 Android NDK r8c。

这是我尝试配置 pjsip 时的输出。

$ ./configure-android

这是 config.log 的摘录

谁能告诉我如何解决这个问题......

确保您在 Windows 上以管理员身份启动 Cygwin，如果不这样做，我会很挣扎^^

我设法克服了那个错误，但仍然没有设法编译 pjsip。我切换到linux，一切正常......

如果您查看 config.log，您会看到如下内容：

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 >&5

C:/android-ndk-r9/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../ ../../arm-linux-androideabi/bin/ld.exe：找不到-lc

NDK 的 ld.exe 正在寻找 libc（位于 arch-arm/usr/lib/ 中），但它不喜欢 cygwin 路径。在configure-android改行

导出 LDFLAGS="${LDFLAGS} -nostdlib -L${ANDROID_SYSROOT}/usr/lib/"

像这样：

导出 LDFLAGS="${LDFLAGS} -nostdlib -Lc:/android-ndk-r9/platforms/android-18/arch-arm/usr/lib/"
