# gunzip poco-XYtar.gz# tar -xf poco-XYtar# cd poco-XY# ./configure# gmake -s In the above steps, you have assumed that the first step is to install MySQL. And ODBC, if the user does not install, you need to declare this step in the ./configure specified directory. Parameter explanation: --omit exclude (not compiled), --prefix installation path, command sample (prefix part can not be written): 
# ./configure --omit=Data/ODBC,Data/SQLite -- Prefix=/usr --static --shared If there is no --static --shared The default is shared Do not compile static library Attach a piece of experience from the network: If you use static library under x64 system, remember to add -fPIC, Dynamic library does not need . ./configure --omit=Data/ODBC, Data/SQLite --prefix=/usr --cflags=-fPIC --static above, do not forget the last command: 
# gmake -s Install At this point, the installation of POCO on CentOS7 ended successfully.
