cannot configure libcurl with SSL support for Android

[AnDu]

I'am trying to compile libcurl 7.30.0 with SSL support for a native Android application. I am using Cygwin. I have followed these steps:

 - creating standalone tool-chain: /cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/build/tools/make-standalone-toolchain.sh --ndk-dir=/cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/ --system=windows --install-dir=/cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/standalone --platform=android-14

export PATH=/cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/standalone/sysroot:$PATH

export PATH=/cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/standalone/bin:$PATH

- compiling libcurl:./configure --host=arm-linux-androideabi --with-ssl=/cygdrive/c/Android/android-sdk/external/openssl --with-random=/dev/urandom --with-sysroot=/cygdrive/d/android-ndk-r8b-windows/android-ndk-r8b/standalone/sysroot --enable-tls-srp

make

In /cygdrive/c/Android/android-sdk/external/openssl I have libcrypto.a and libssl.a previously compiled. But ./configure fails to enable SSL, the following is a copy paste from config.log from curl:

configure:21548: PKG_CONFIG_LIBDIR will be set to "/cygdrive/c/Android/android-sdk/external/openssl/lib/pkgconfig"

Anybody has an idea how can I solve this issue?

Thanks a lot!

I succeeded configuring without errors by running ./configure command in bash.exe from Cygwin, instead of using Cygwin terminal.
