This is a port of pkg-config 0.25 to MSDOS/DJGPP.
The pkg-config program is used to retrieve information about installed
libraries in the system. It is typically used to compile and to link
against one or more libraries.
DJGPP specific changes.
- The port honours the PATH_SEPARATOR environment variable to select
the path separator to be used. If no one is given it defaults to
semi-colon as seprator.
- This pkg-config version is the last one that can be compiled with
disabled multi-threading support. All later pkg-config versions no
longer include the GLib library and those library versions require
MT support that can only be provided by one of the two DJGPP ports
either pth207b or fpth314b. Neither of them perform really well.
Although pth207b has the more complete pthread implementation it
requires the installation of the Watt-32 library. Also it may be
necessary to recompile the library to get the required functionalities
available. Due to the amount of work to get the GLib library working
on DOS I have decided that the effort is not worth the result.
DOS is and will always be a single user single task OS where all
multi-threading efforts are superflous.
- The port has been configured to be used as a tool in the DJGPP
enviroment, thus all internal path assumptions are done based
on the value of the DJDIR environment variable. If it is not
set, the tool will not work properly. If you want to use the
program as a stand alone tool then you will have to set all its
controling environment variables to the appropriate values.
- The port has been configured and compiled on WinXP SP3, Win98SE and
MS-DOS 6.22 with DOSLFN v0.41f. There is no guarantee that this may
be possible with any other DOS-like OS. Due to the use of long file
names it will not be possible to configure and compile without LFN
support. The port has been compiled using gcc346 and bnu2351b.
As usual, all djgpp specific files (diffs, README files, etc.) are
stored in the "djgpp" directory. The sources have been configured
to be build in the "0build" directory. If for some reason it does
not work for you, delete its contents and configure from scratch
Please read the docs to become familiar with this product.
Here is an extract of the NEWS file showing the user visible changes
from the last port (pkg-config 0.23) to this one:
- 0.24 included a too strict whitespace/shell metacharacter filter
leading to some legal characters like = and : being escaped in the
output. This has been fixed.
- when building with newer and external libpopt, it would be confused
over being asked to split an empty string, leading to errors with
packages that included empty fields in their .pc files.
- Make the COPYING file explicitly GPLv2. The COPYING file in 0.24
was inadvertently GPLv3 rather than the correct GPLv2.
- Minor changes to documentation
- Fix up bug in PKG_CONFIG_SYSROOT handling which mangled non-I and
- Put /usr/lib/pkgconfig and /usr/share/pkgconfig into the default
search path when no prefix is passed to configure.
- Portability fixes for Windows and NetBSD
- Various man page updates
- Add logging support to log how pkg-config is being called.
- Skip Requires.private unless we need them for Cflags
- Add a variable, pc_path to the compiled-in pkg-config package that
you can query for the compiled-in PKG_CONFIG_PC_PATH.
- Various updates to pkg.m4.
- Update rpmvercmp with bugfixes from upstream.
- Add introductory guide to pkg-config, thanks to Dan Nicholson for
- Add listing of variables in a package
- Make it possible to use external popt.
- Add --print-provides and --print-requires(-private) options
- Add support for paths containing whitespace and shell metacharacters
