This convention follows that of man files written in mdoc, contributes to the clarity of the source code, and simplifies the tracking of changes. Updating a sentence may require reformatting it into 72 columns, which affects the entire block of text in question. In this case, the change is now limited to the single sentence rather than the entire paragraph.

Remove CMake support

Several updates to the Makefile

2026-05-13T12:53:26Z

commit bd3891b42e548e0f239c3c3610bc808df56bd31e parent 82c77fb069073aae8fa264f1916791f631e2c3f5 Author: Vincent Forest Date: Wed, 13 May 2026 14:53:26 +0200 Several updates to the Makefile Delete the make.sh script. It implemented functions which, while contributing to the clarity of the Makefile, made the build system less compact. All these functions can be implemented with just a few lines of shell code, without any major impact on the clarity of the Makefile. Perhaps on the contrary, since it's all in one place. Add the LIBPREFIX and INCPREFIX macros to control the subdirectories into which libraries and header files are copied. Systems may use locations other than those proposed by default. Remove the "distclean" Makefile target. In fact, it does the wrong thing. distclean, in addition to a normal cleanup target, should also delete files created by a dist target, i.e. a target generating files for distribution, such as a compressed archive. But it was used to delete automatically generated dependency files. These files can simply be removed by normal cleanup. What's more, as the project is designed to be installed by compiling its sources directly, no distribution target is implemented, so no distclean is required. Dependencies are grouped in the INCS and LIBS macros using a single call to the pkg-config program. In the Makefile, the CFLAGS and LDFLAGS variables for the library and tests have been written into their own macro to make the command lines more compact. Dependency checking is now performed with as few call to pkg-config, without any additional code, because displaying a hand-written error message adds no value to the clarity of what is being done and what happens in case of missing dependencies.

Make generated binaries safer and more robust

2023-10-12T14:47:46Z

commit 82c77fb069073aae8fa264f1916791f631e2c3f5 parent 414ed3449df205cdb104e5a999266d6205ff6d4e Author: Vincent Forest Date: Thu, 12 Oct 2023 16:47:46 +0200 Make generated binaries safer and more robust Define the CFLAGS_HARDENED and LDFLAGS_HARDENED macros, which list compiler and linker options that activate various hardening features aimed at increasing the security and robustness of generated binaries. The link editor options have all been available since at least ld 2.25. So you don't have to worry about compatibility issues. The compiler options are in fact some of those that will be enabled by the -fhardened option to be introduced in GCC 14. In the following, we list them and indicate the version of GCC from which they are documented in the manual, i.e. from which version of GCC they would appear to be available: -D_FORTIFY_SOURCE [GCC 5.5] -fcf-protection options [GCC 8.5] -fstack-protector-strong [GCC 6.5] -fstack-clash-protection [GCC 8.5] -ftrivial-auto-var-init [GCC 12.3] The latter, -ftrivial-auto-var-init, is too recent. To avoid any compatibility problems, we haven't activated it yet.

Write a POSIX Makefile to replace CMake

2023-10-12T10:06:19Z

commit bd09b0edcf81dc3e2cc81c3c2d955ffac4911a39 parent dddb6d83cfc96380cff1db18415967ddc629e33b Author: Vincent Forest Date: Thu, 12 Oct 2023 12:06:19 +0200 Write a POSIX Makefile to replace CMake The build procedure is written in POSIX make, which the user can configure via the config.mk file. The make.sh script contains commands that could be found directly in POSIX make, but which are placed here to simplify writing the Makefile. Finally, a pkg-config file is provided to link the library as an external dependency. In addition to the features already provided in its CMake alternative, this Makefile supports the construction of static libraries and provides an uninstall target. In any case, the main motivation behind its writing is to use a good old well-established standard with simple features, available on all UNIX systems, thus simplifying its portability and support while being much lighter.

The resulting acceleration structures are comparable to the ones built by previous Star-3D versions that rely on Embree2 rather than Embree3. Per realisation performances are thus comparable while previously, Star-3D with Embree3 was up to 5 times slower than Star-3D with Embree2 since its build criteria were far more exigents.

commit 47de63c3c9a62ef4b0c5a605154c811393d9cdd1 parent e22a1821b16b63a81a32d4b1c33b30d9da6eee71 Author: Vincent Forest Date: Thu, 15 Oct 2015 14:50:50 +0200 Fix the Schiff estimator whit several sampled directions The Monte Carlo weight of the sampled directions were incorrectly accumulated. Let N directions sampled for a given geometry, the resulting MC weight is W = 1/N Sum_i^N(w).
