SQLite ICU MinGW

Let us create “sqlite/build” subfolder and attempt to run a default build:

#!/bin/bash

cd ./sqlite
mkdir -p build && cd ./build
../configure
make -j4

Configure created “Makefile” and five other files in the “build” folder and exited successfully. “make” should have generated additional files/folders but it failed with error message containing references to files in /usr/include. Note, /usr/include folder belong to the MSYS toolchain, so MinGW and MSYS toolchains have been mixed. “make” should only use files located inside ${MINGW_PREFIX} and its subfolders, but inspection of the compiler’s command line reveals “-I/usr/include” option.

The “sqlite/build/Makefile” should be inspected next, and it provides a hint that configure script generated this option for the TCL library (compare with “sqlite/Makefile.in”). TCL is used extensively by the SQLite build process for preprocessing of the source files. The makefile also builds a TCL-SQLite interface. To find TCL-related compiler options, the configure script looks for the “tclsh” file and checks for several versioned variants first. Note that MSYS/MinGW setup described above installs TCL in all toolchains. The “tclsh” file has a version suffix in the MSYS package but not in the MinGW package. Because both MinGW and MSYS binary directories are in the path, configure picks the wrong TCL package. Also, note that “$(READLINE_FLAGS)” in the “sqlite/build/Makefile” points to the MSYS toolchain. The SQLite configure script has options:

  • ”–with-tcl=DIR” - directory containing tcl configuration (tclConfig.sh);
  • ”–with-readline-lib” - specify readline library;
  • ”–with-readline-inc” - specify readline include paths.

It turns out that “$(READLINE_FLAGS)” does not affect the build process, and we will fix it in the final script. Let us add the “–with-tcl=${MINGW_PREFIX}/lib” configure option only and run configure/Makefile again. “make” should fail with a “libtool” error message about library linking. According to information available from the Internet, “libtool” has a bug. To skip the problematic code section, “configure” should be executed as follows:

lt_cv_deplibs_check_method="pass_all" ../configure "--with-tcl=${MINGW_PREFIX}/lib

and “make” should now succeed.
