Package libcurl was not found in the pkgconfig search path.

1、问题

2、检查相关变量、目录

root@PC1:/test# locate libcurl.pc
root@PC1:/test# echo PKG_CONFIG_PATH
PKG_CONFIG_PATH
root@PC1:/test# ls /usr/lib/pkgconfig/
ibus-table.pc  libR.pc
root@PC1:/test#

3、

 wget https://curl.haxx.se/download/curl-7.65.3.tar.xz

root@PC1:/home/software# tar xf curl-7.65.3.tar.xz

root@PC1:/home/software# cd curl-7.65.3/

root@PC1:/home/software/curl-7.65.3# ./configure --prefix=/usr --disable-static --enable-threaded-resolver --with-ca-path=/etc/ssl/certs

root@PC1:/home/software/curl-7.65.3# make

root@PC1:/home/software/curl-7.65.3# make install && rm -rf docs/examples/.deps && find docs \( -name Makefile\* -o -name \*.1 -o -name \*.3 \) -exec rm {} \; && install -v -d -m755 /usr/share/doc/curl-7.65.3 && cp -v -R docs/*     /usr/share/doc/curl-7.65.3

4、检查配置文件 libcurl.pc

root@PC1:/home/software/curl-7.65.3# find / -name "libcurl.pc"
/home/software/curl-7.65.3/libcurl.pc
/usr/lib/pkgconfig/libcurl.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/libcurl.pc

5、测试，。。。。。， 貌似这个问题解决了
