为 arm-linux-gnueabi 构建 libcurl：为什么 curl 忽略 openssl？

Question

1。构建openssl

git clone https://github.com/openssl/openssl.git -b OpenSSL_1_1_1-stable --depth 1 openssl-1.1.1
cd openssl-1.1.1
./Configure --prefix=/usr linux-generic32 shared  \
      --cross-compile-prefix=arm-linux-gnueabihf-
make depend -j7
make -j7
make DESTDIR=/Volumes/lpd-dev/armhf/ install_sw install_ssldirs

2。构建卷曲

git clone https://github.com/curl/curl.git -b curl-7_64_1 --depth 1 curl-7.64.1
cd curl-7.64.1
./buildconf
./configure --host=arm-linux-gnueabihf --prefix=/usr --with-ssl=/Volumes/lpd-dev/armhf/usr

这个输出：

...

dev/armhf/usr/lib/pkgconfig"

已找到 pkgconfig，但警告：SSL 已禁用

Answer 1

在写问题的过程中，我重读了更多./configure 的输出，并理解“/Volumes/lpd-dev/armhf/usr/lib/pkgconfig”指向--prefix=/usr，但由于我们是交叉编译点到错误的位置！

只需移动或删除.../armhf/usr/lib/pkgconfig 已解决的问题。

    ...
