android 交叉编译 openconnect-8.08 时出错

Question

当我按照说明 here 进行操作时，我在运行最新说明 "make" 时收到此错误：

make[1]: Entering directory '/home/fasegiar/Downloads/openconnect-8.08'

我使用的目标是：armv7a-linux-androideabi

我的工具链是：/home/fasegiar/Documents/android-ndk-r21/toolchains/llvm/prebuilt/linux-x86_64

Here is the output of the config.log after ./configure call

根据您发布的代码片段，我已经可以告诉您这是行不通的。交叉编译时，您需要首先针对您的目标平台（即Android）交叉编译所有依赖项，然后告诉配置脚本在哪里可以找到已安装的依赖项。对于 openconnect，依赖项是：

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)
