When i follow instructions here, i get this error when running latest instruction that is "make":
make[1]: Entering directory '/home/fasegiar/Downloads/openconnect-8.08'

The TARGET that i use is: armv7a-linux-androideabi
My TOOLCHAIN is: /home/fasegiar/Documents/android-ndk-r21/toolchains/llvm/prebuilt/linux-x86_64
Here is the output of the config.log after ./configure call
回答1:
From the snippet you posted I can already tell you this is not going to work. When cross-compiling you need to cross-compile all dependencies first for your target platform (ie Android) and then tell the configure script where to find the installed dependencies. For openconnect the dependencies are:
Required:
- libxml2 (this in turn requires libicu, as your error points out)
- zlib (this is bundled)
- Either OpenSSL or GnuTLS (v3.2.10+) (see NDKPorts)
Optional:
- p11-kit (for PKCS#11 support)
- libp11 (also needed for PKCS#11 support if using OpenSSL)
- libproxy
- trousers (for TPMv1 support if using GnuTLS)
- libtasn1 and either tss2-esys or IBM's TPM 2.0 TSS. (for TPMv2 support if using GnuTLS)
- libstoken (for SecurID software token support)
- libpskc (for RFC6030 PSKC file storage of HOTP/TOTP keys)
- libpcsclite (for Yubikey hardware HOTP/HOTP support)
