下载libpq库
找了以打晌儿就是找不到咋办放弃吧等等好像在postgresql源码中。
下载源码看看有没有。
官网走起https://www.postgresql.org/
两会期间网速贼慢物理吐槽等版半天打开了一次就不知道怎么遭到下载地址了。
先按照ubuntu18源中的版本进行下载。
$ dpkg -L libpq-dev | grep -F .pc | xargs cat
Name: libpq
Description: PostgreSQL libpq library
Url: http://www.postgresql.org/
Version: 10.23
Requires:
Requires.private:
Cflags: -I/usr/include/postgresql
Libs: -L/usr/lib/x86_64-linux-gnu -lpq
Libs.private: -L/usr/lib/x86_64-linux-gnu/mit-krb5 -lssl -lcrypto -lgssapi_krb5 -lcrypt -lldap_r
最终的下载位置为https://ftp.postgresql.org/pub/source/v10.23/postgresql-10.23.tar.gz 需要其他版本呢自己找,自己在官网找好了。
看看有没有libpq库
解压后搜一下libpq关键字

If you have readline already installed, see config.log for details on the

尝试单独编译libpq库
人家就是不支持非得单独编译嗨
头文件直接不分离实在不行开发时把真个头文件目录整个拷贝过去多了也没有关系。

好像没有问题
编译
make make install
报错

CNMconfigure时不报错非得在编译时报错。
再编译
./configure --prefix/opt/libpqxx --with-postgres-include/opt/postgresql/include --with-postgres-lib/opt/postgresql/lib --disable-documentation make make install

操了没有动态库。make clean再来。
再再编译
make clean ./configure --prefix/opt/libpqxx --with-postgres-include/opt/postgresql/include --with-postgres-lib/opt/postgresql/lib --disable-documentation --enable-sharedyes make make install
