2023-08-06move release version into VERSION.txtBrandon Maier1-6/+2
To synchronize the release version of the Makefile and Meson build systems, pull the version info from a shared file. Meson requires that the shared library version follow the X.Y.Z numbering scheme. But the Makefile supported building shared libraries with an EXTRAVERSION appended, for example X.Y.Z-rc1. We want to keep the output of both systems the same to avoid issues, so we drop support for the Makefile EXTRAVERSION.

2023-05-14yaml: Depend on libyaml >= 0.2.3Uwe Kleine-König1-1/+5
libyaml before 0.2.3 expects non-const string parameters. Supporting both variants would require either cpp magic or ignoring "discarded-qualifiers" compiler warnings. For the sake of simplicity just support libyaml 0.2.3 and newer. Note that NO_YAML can be overwritten on the make command line. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

2022-09-26Makefile: fix infinite recursion by dropping non-existent `%.output`Sergei Trofimovich1-1/+1
Without the change GNU `make-4.4` falls into infinite recursion of trying to generate %.output files (bison is not passed flags to generate debug output). This happens on GNU `make-4.4` only after GNU make change to more eagerly rebuild all target outputs in multiple targets: https://savannah.gnu.org/bugs/index.php?63098 The recursion here is the following: - Makefile depends on *.d files - *.d files depend on *.c files - *.c files are generated by bison - bison is triggered whenever some of it's multiple targets are missing In our case `%.output` is always missing and bison is always reran. *.d files are always regenerated on `make` run. And make is always restarted as *.d files are always regenerated. The fix removes infeasible `%.output`.

2022-09-26Makefile: limit make re-execution to avoid infinite spinSergei Trofimovich1-0/+4
make-4.4 became intentionally more eager at rebuilding outdated Makefile includes. Currently this causes `dtc` to spin infinitely in parser/dependency loop: $ make ...

2020-03-04Encode $(NO_PYTHON) consistently with other variablesDavid Gibson1-3/+5
We have several $(NO_*) variables used to disable optional features. $(NO_PYTHON) is encoded as empty for "include Python support" and anything else for "disable Python support". However the other variables - $(NO_YAML) and $(NO_VALGRIND) - use 0 for "include" and 1 for "disable". Change $(NO_PYTHON) to work consistently with the others.

Add a new ASSUME_MASK option, which allows for some control over the checks used in libfdt.

2019-07-22Makefile: Add EXTRA_CFLAGS variableJoel Stanley1-1/+1
Distributions packaging dtc may need to set extra flags. Currently when they do that it overrides the ones set by the makefile. This is particularly problematic when compiling without yaml, as the yaml detection is ignored. ld: dtc.o: in function `main': dtc.c:(.text.startup+0x718): undefined reference to `dt_to_yaml' This patch provides a EXTRA_CFLAGS variable that is added to the list of CFLAGS, and can be set on the command line when packaging.

2019-05-10Fix bogus error on rebuildDavid Gibson1-1/+1

2019-03-29Link tools and tests against libfdt shared libraryDavid Gibson1-4/+5
Currently the libfdt based tools (fdtput, fdtget, etc.) and all the test binaries using libfdt are linked against the static version of libfdt. That's made it very easy in the past to forget to properly update the version.lds file which is needed to make functions publicaly accessible from the shared library. To avoid problems like that in future, alter the build so that we link and run the tests against the shared library version of libfdt. That immediately points out several important symbols that are still missing from the version.lds, so fix those as well. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-03-29Clean up LDLIBS handlingDavid Gibson1-2/+2
We currently set LDLIBS to include libyaml globally if we're using it. However only dtc itself actually needs to link with libyaml - the other tool binaries don't. Avoid that unnecessary inclusion by making LDLIBS handling per-target. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-03-29Rebuild libfdt shared object if versioning linker script changesDavid Gibson1-5/+5
The usable content of the shared library varies depending on the symbol versions given in the version.lds linker script, however it's not currently in the make dependencies.

2018-09-13Add support for YAML encoded outputGrant Likely1-1/+8
YAML encoded DT is useful for validation of DTs using binding schemas. The YAML encoding is an intermediate format used for validation and is therefore subject to change as needed.

2018-09-10Make valgrind optionalDavid Gibson1-0/+7
Some platforms don't have valgrind support, and sometimes you simply might not want to use valgrind. But at present, dtc, or more specifically its testsuite, won't compile without valgrind because we use the valgrind client interface in some places to improve our testing and suppress false positives. This adds some Makefile detection to correctly handle the case where valgrind is not available. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2018-01-08Avoid installing pylibfdt when dependencies are missingSimon Glass1-8/+16
At present we have a build check that python-dev and swig are available. If they are not, we print a message and skip building pylibfdt. However this check is not currently present with 'make install'. The install is attempted, and fails. See crbug.com/789189 Split the check out into a separate script and use it twice, once for the build and once for the install. This corrects the error.

2017-09-27pylibfdt: Use Python2 explicitlyDavid Gibson1-1/+1
The pylibfdt code is written for Python2, not Python3. So, it's safer to explicitly request Python2 in our scripts and when checking pkg-config. On Arch Linux at least, there isn't actually a plain "python" link, just "python2" and "python3", so the current setup won't work at all. According to https://www.python.org/dev/peps/pep-0394/ using "python2" should work, and is preferred. Updating pylibfdt to work with Python3 would be nice, but is a problem for another day.

2017-04-08pylibfdt: Allow setup.py to operate stand-aloneSimon Glass1-0/+1
At present we require that setup.py is executed from the Makefile, which sets up various important things like the list of files to build and the version number. However many installation systems expect to be able to change to the directory containing setup.py and run it. This allows them to support (for example) building/installing for multiple Python versions, varying installation paths, particular C flags, etc. The problem in implementing this is that we don't want to duplicate the information in the Makefile. A common solution (so I am told) is to parse the Makefile to obtain the required information. Update the setup.py script to read a few Makefiles when it does not see the required information in its environment.
