c - libcurl 出现编译错误

Question

我正在尝试使用 Openssl 和 SSH2(手动构建)编译 libcurl。这是我的配置命令:

./configure  --with-ssl=/home/yuvi/development/openssl --with-libssh2=/home/yuvi/development/ssh --enable-debug --prefix=/home/yuvi/development/curl CPPFLAGS="-I/home/yuvi/development/openssl/include -I/home/yuvi/development/ssh/include" LDFLAGS="-L/home/yuvi/development/openssl/lib -L/home/yuvi/development/ssh/lib" PKG_CONFIG_PATH=/home/yuvi/development/openssl/lib/pkgconfig:/home/yuvi/development/ssh/lib/pkgconfig LIBS="-lssl -lssh2 -lcrypto"

在 libtool 阶段我遇到以下错误:

有人可以帮我吗？我错过了什么？

您需要使用 -fPIC 重新编译/home/yuvi/development/openssl/lib/libssl.a
