Android 在windows上编译pjsip“；C编译器无法创建可执行文件；

我在windows上通过cygwin编译pjsip时遇到问题。 我尝试使用pjsip表单的android branc 以及适用于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

有人能告诉我如何解决这个问题吗…

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

我设法克服了这个错误，但仍然没有编译pjsip。我切换到了linux，在linux中，一切都正常运行……

如果您查看config.log，您将看到如下内容：

a数字：2841： /cygdrive/c/android-ndk-r9/toolschains/arm-linux-androideabi-4.4.3/prebuild/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/c/android-ndk-r9/platforms/lib/conftest.c-lc-lgcc>&5

C:/android-ndk-r9/toolschains/arm-linux-androideabi-4.4.3/prebuild/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（在arch-arm/usr/lib/中），但它不喜欢cygwin路径。行中的更改

export LDFLAGS=“${LDFLAGS}-nostdlib-L${ANDROID\u SYSROOT}/usr/lib/”

对这样的事情：

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

我对777 ndk dir结构进行了建模…您是否检查了有错误的行？（27702823，…），您是否也对ndk目录或/ndk/toolchains/arm-linux-AndroidABI-4.4.3/prebuild/windows/bin目录进行了chmod？1.我不知道要查找什么2770IS（eval“$ac_编译器$ac_选项>&5”）2>conftest.err ln2823 is（eval“$ac_链接默认值”）2>&5。。。。2.嗯，我递归地对它进行了建模。。。应该没问题……你还记得你是怎么通过这个错误的吗？也许你能帮我。谢谢
