Author: tml Date: 2001-09-29 21:05:25 GMT 2001-09-30 Tor Lillqvist <tml@iki.fi> Changes for "pure" Win32 (without Cygwin or similar) support. The most important differences compared to pkg-config on Unix are: We don't use hardcoded PKGLIBDIR paths but deduce the installation prefix at runtime. Use the normal GLib DLL, not a private copy. Yes, this does introduce a circular dependency, but that can be worked around. * README.win32: New file. * configure.in: Check for Win32. If so, define USE_INSTALLED_GLIB, and don't configure in the included glib-1.2.8. Set GLIB_CFLAGS and GLIB_LIBS assuming that GLib is installed in the same location pkgconfig will be. Check for dirent.h, unistd.h and sys/wait.h headers. * Makefile.am: If USE_INSTALLED_GLIB, use the GLIB_* values set above, and don't make in the glib-1.2.8 subdir. * autogen.sh: Use perl -p -i.bak, works better on Win32 (and Cygwin). * *.c: Conditionalize inclusions of unistd.h and sys/wait.h. * findme.c: Define X_OK on Win32 if necessary. * parse.c * popthelp.c: Minor Win32 portability ifdefs. * parse.c: No need to include <windows.h>. * pkg.c: Don't hardcode PKGLIBDIR, but use g_win32_get_package_installation_directory() to deduce it. (scan_dir): Make a temp copy of dirname with potential superfluous trailing slash removed. The Win32 opendir implementation doesn't always like those. * pkg.h: If USE_INSTALLED_GLIB, include <glib.h> instead of partial-glib.h. * popt.c (execCommand): Don't compile on Win32. * poptconfig.c (configLine): Don't bother with the "exec" stuff on Win32, too complex to port, at least for now. (poptReadDefaultConfig) Don't bother compiling on Win32, this function isn't even called.
