Compile Readline for x86 system (static mode)

I am writing a program in QT Creator, for the x86 architecture, using Debian 9 x86. The program will use GNU Readline library [8.0]. Also, my program must be statically built (QT is already statically built). For this I downloaded Readline from here. Then performed the configuration for the static assembly:

./configure —prefix=/home/out/readlinelibs/ —enable-static —with-curses

then i performed the construction:

make

and installing libraries

make install

In QT's pro file I added the path to the libraries:

LIBS += -L/home/out/readlinelibs/lib -static -lreadline -ltinfo

When compiling the program I get the following error in QT:

error: cannot find -ltinfo

How to build readline in static mode? Thanks.

P.S.: in Debian x64 I also built readline and everything works well.

Solution

  • It was the lack of a tinfo library, as mbieren advised. I performed the installation on a 64-bit system as follows:

    1. Added ability to install 32-bit packages:

      sudo dpkg --add-architecture i386

    2. I scanned the package and found that i need. You can do the scan so:

      sudo apt-cache search tinfo

    3. Finally i installed that i need:

      sudo apt-get install lib32tinfo5 lib32tinfo-dev

    Now the compilation of my program for 32-bit architecture is completed successfully!
