flex: rework patches to avoid host/target difference

2017-10-11T21:51:47+00:00

Currently, the target and host flex packages do not behave the same in terms of patching: the target variant has a patch hook that disables building the programs (because they are not needed, and do not build on no-MMU platforms). However, this hook is obviously not executed for host-flex, because we really want the host flex binary to be built. In preparation for the introduction of out-of-tree package build, it is important that we don't do different things in the patch hooks for the target and host variant of a given package, because the source tree will be shared between the target and host builds. To solve this, we introduce a --disable-program configure option, through a patch to the flex configure.ac and Makefile.am. This patch makes the current 0001-flex-disable-documentation.patch no longer needed. Furthermore, building the documentation is a PITA: flex.1 depends on configure.ac and a few other files generated during the build. Touching flex.1 does not work, because automake will forcibly remove the files when its prerequisites are too old, so pre-requisites of flex.1 will always be more recent than flex.1. So, we add a patch that adds a --disable-doc configure option.

flex: Fix segfault of stage1flex when host has glibc 2.26 or newer

2017-09-27T21:28:35+00:00

When the host uses glibc 2.26 or newer, Flex will try to use the newly-introduced reallocarray() function, but as it would not define _GNU_SOURCE a segmentation fault would occur later on due to the compiler assumming that the function is implicitly defined. This issue manifests itself due to a crash of "stage1flex" during the Flex bootstrap: ./stage1flex -o stage1scan.c ./scan.l make[2]: *** [Makefile:1725: stage1scan.c] Segmentation fault (core dumped) This imports the patch from the upstream Git repository, and adds flags in the .mk file to rebuild the Autotools scripts and support files. Due to the latter, the patch to disable the documentation is changed so it modifies the .am file instead. Signed-off-by: Adrian Perez de Castro [Arnout: - Add Adrian's Sob and upstream ref to new patch; - Keep patch 1 as patch 1; - Keep Vicente as author of path 1; - Add reason for autoreconf in a comment.] Signed-off-by: Arnout Vandecappelle (Essensium/Mind)

package/flex: disable reallocarray

2017-09-27T20:56:32+00:00

This doesn't compile with glibc 2.26 where reallocarray() as been introduced. It's a nasty issue, when reallocarray() is available for the target, flex will build a small tool called stage1flex for the host (using _FOR_BUILD) but with the config.h generated for the target. When the host doesn't have a glibc >= 2.26, reallocarray() is never defined while building stage1flex: misc.c:147:8: warning : implicit declaration of function « reallocarray » [-Wimplicit-function-declaration] mem = reallocarray(NULL, (size_t) size, element_size); ^~~~~~~~~~~~ misc.c:147:6: warning : assignment makes pointer from integer without a cast [-Wint-conversion] mem = reallocarray(NULL, (size_t) size, element_size); ^ Disable reallocarray for now, reallocarray() support may be enabled in a followup patch. Fixes: stage1flex-misc.o: In function `allocate_array': misc.c:(.text+0x38f): undefined reference to `reallocarray' stage1flex-misc.o: In function `reallocate_array': misc.c:(.text+0xc8a): undefined reference to `reallocarray' collect2: error: ld returned 1 exit status Signed-off-by: Romain Naour Signed-off-by: Arnout Vandecappelle (Essensium/Mind)

flex: use the new gettext logic

2017-07-04T23:27:25+00:00

This commit switches to use the new gettext logic, which involves: - using TARGET_NLS_DEPENDENCIES instead of hand-encoded dependencies on gettext/host-gettext - dropping BR2_PACKAGE_GETTEXT selection Signed-off-by: Thomas Petazzoni

flex: remove bogus comment

2017-07-04T17:09:42+00:00

The comment that explains why we were defining HOST_FLEX_DEPENDENCIES instead of inheriting from FLEX_DEPENDENCIES no longer makes sense, since we remove such automatic inheritance of host dependencies from target dependencies a while ago.

flex: only prevent the flex binary to be built for target, not for host

2017-05-23T13:48:02+00:00

We do want to build the flex binary when building host-flex since it's needed as a build dependency for other packages. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

flex: bump version to 2.6.4

2017-05-11T19:43:53+00:00

- 0001 patch removed. It doesn't apply on this version and is also not necessary since the AR binary is now handled correctly with AR = @AR@. - 0002 patch removed. It's already included in this release: https://github.com/westes/flex/commit/a5cbe929ac3255d371e698f62dc256afe7006466 - The flex project has moved to GitHub, so modify the URLs in both flex.mk and Config.in files. - The sed command over Makefile.in to prevent the flex binary to be built fails, so remove it. That logic has been moved to src/Makefile.in, and whenever we disable the flex binary to be built then the compilation fails when building the documentation because some bits require "../src/flex", which is the flex binary. We prevent building the flex binary and the documentation using a new patch. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni
