Error while compiling static Qt 5.10.0 with PostgreSQL

Question

I'm trying to compile Qt 5.10.0 with PostgreSQL 10 (or 9.2, but same error) using mingw on Windows 7.

However when I include the psql include and lib dirs I always get the following Error after mingw32-make:

I googled and found a thread on the qt forums where someone had the same Error, but no solution: https://forum.qt.io/topic/66218/trubble-with-static-qt5-6-0-with-qt-sql-psql-compiling-from-source

My configure command looks like this:

configure -prefix C:\Qt\Static\5.10.0 -static -release -nomake tests -nomake   examples -confirm-license -I"C:\POSTGRESQL\10\include" -L"C:\POSTGRESQL\10\lib" -opensource -qt-zlib -qt-libpng -qt-libjpeg -sql-psql -opengl desktop

the compilation works just fine if I remove

-I"C:\POSTGRESQL\10\include"
-L"C:\POSTGRESQL\10\lib"

but without psql obviously.

Any ideas on how to resolve this issue would be highly appreciated, thanks.

It seems like you haven't built Qt recently (post 5.8) - the -I and -L configuration syntax is no longer supported.

For me postgres just works, all I need is the -sql-psql configuration flag and the library in my system path.

If that alone doesn't work, you could specify the paths via the addition of the following configuration flags:

PSQL_INCDIR=C:\POSTGRESQL\10\include
PSQL_LIBDIR=C:\POSTGRESQL\10\lib
